Furthermore, processing (cutting) of the workpiece W by the above-mentioned workpiece processing apparatus (the lathe module 30A) will be explained along the flowchart shown in FIG. The control device 47 executes processing according to this flowchart.

In step S102, the control device 47 determines whether there is an instruction to start machining a new workpiece W (predetermined quantity) in the lathe module 30A. If a machining program for machining the workpiece W has been newly started, the control device 47 determines that there is an instruction to start machining the workpiece W ("YES" in step S102), and steps the program. Proceed to S104. If the machining program for machining the workpiece W has not been newly started, the control device 47 determines that there is no instruction to start machining the workpiece W (“NO” in step S102), and starts processing the workpiece W. The determination process in step S102 is repeatedly performed until an instruction to start machining is received.

In step S104, the control device 47 determines whether there has been an instruction to end the machining of the workpiece W (predetermined quantity) that was started earlier. When the machining program has been completed for all the predetermined quantities, the control device 47 determines that there has been an instruction to end the machining of the workpiece W ("YES" in step S104), and ends this flowchart. If the machining program has not ended, the control device 47 determines that there is no instruction to end the machining of the workpiece W ("NO" in step S104), and advances the program to step S106.

In step S106, the control device 47 processes the workpiece W according to the processing program. The machining program includes one or more machining instructions (machining sub-process) for machining (machining) the work W by the cutting tool 43a and non-machining instructions for not machining the work W. , perform machining processing and non-machining processing in accordance with the order of the machining program.

Processing includes cutting, grinding, and the like. Cutting processes include turning, in which a cutting tool is applied to a rotating workpiece W using a lathe or turning center, and milling, in which a rotating cutting tool is applied to a fixed workpiece, using a machining center or milling machine. This includes drilling holes by applying a rotating drill to a fixed workpiece W using a machining center or a drilling machine.

The machining process command is a command (command) for performing machining process, and for example, a block that includes "G1", which is a cutting feed command, "G2", "G3", which are circular interpolation commands, etc. in the G code. (For example, blocks B1, B5-B7 shown in FIG. 5).

In step S108, the control device 47 converts the machining load, which is a physical quantity related to the machining of the work W and is a detectable physical quantity, into machining data D (the machining data D is actual detection data that is actually detected). ) (detection unit). Specifically, the machining load is a load generated when cutting (machining) the workpiece W with the cutting tool 43a, and is a physical quantity (machining resistance) that acts as resistance to machining. Here, the machining load is the force exerted by the workpiece W and the cutting tool 43a (the driven side) that generate machining resistance on the driving side (in this embodiment, each of the above-mentioned servo motors) and the energy consumed. For example, it refers to the torque load applied to the drive shaft.

In step S108, the control device 47 acquires the drive current of the servo motor 42d for driving the spindle 42a from the current sensor 42e that detects the drive current, and uses the detected current to determine the machining load of the servo motor 42d (torque load applied to the spindle 42a). (spindle machining load)) can be derived. For example, the machining load is derived as the machining load corresponding to the detected current by using a map or an arithmetic expression showing the correlation between the drive current and the machining load. Note that this correlation is such that the larger the processing load, the larger the drive current. Similarly to the spindle machining load, the X-axis machining load, which is the machining load of the servo motor 44a2, and the Z-axis machining load, which is the machining load of the servo motor 44b2, can also be derived.

Note that processing load detection is performed every predetermined short time (the sampling period in this embodiment is several msec (for example, 8 msec)). Detection of machining load is carried out at multiple predetermined machining points in a series of machining programs (machining processes).If the machining program is the same, the machining load is detected at the same machining point for each workpiece W. It is possible to detect each. In other words, even in machining sub-processes that correspond to multiple machining instructions included in a machining program, machining load detection is performed at multiple predetermined machining points. processing command), it is possible to detect the machining load at the same machining point for each workpiece W.

For example, the machining load is detected and stored for each machining point for each machining count. In other words, each machining point (sampling point) of the machining data (sampling data) of the first work machining and each machining point (sampling point) of each sampling data of the second and subsequent work machining are all the same machining point. be. The machining point is, for example, an arbitrary machining location during the machining process or even during the machining sub-step, and may also be the machining time, that is, the elapsed time from the machining start time.

In step S110, the control device 47 stores the detected processing load (actual detection data) in the storage device 47b as a series of load data (processing data D (see FIGS. 5 and 6)). The machining data D is stored at machining points (at sampling period intervals) for each workpiece W to be machined. In other words, the load data for each workpiece W can be stored in association with the machining point. That is, the machining correspondence data Da can be associated with a machining sub-process via a machining point, and can further be associated with a machining command associated with the machining sub-process. In this way, the processed data D includes a plurality of pieces of processing corresponding data Da that can be associated with each of the above-mentioned processing commands. For example, FIG. 5 shows a part of the machining data D, and the machining corresponding data Da is load data included in the load monitoring ranges R1 to R14, respectively, and is generated when machining the workpiece W. This is the load data. In this way, the processes in steps S106 to S110 described above are processes for sampling load data.

(Monitoring range automatic specification process)
Next, the control device 47 automatically specifies a monitoring range for monitoring the state of the processing load (detectable physical quantity) (step S114: automatic specifying section). Note that the monitoring range is a range for monitoring (determining) the state of the machining load (detectable physical quantity) along the machining process. If the load data is within the upper and lower limits of the monitoring range, the processing load is in a normal state, and if it is outside the monitoring range, the processing load is in an abnormal state. The monitoring range is the range from the monitoring start point where monitoring starts to the monitoring end point where monitoring ends (this range may be referred to as a monitoring section) in the direction along the processing process. The monitoring range is a range defined by an upper limit value and a lower limit value in a direction along the magnitude of the processing load.

Specifically, the control device 47 advances the program after processing in step S110 to step S112, and determines whether the flag F1 is 1 or not. The control device 47 determines that the flag F1 is "0" from the start of machining the workpiece W until the end of the automatic designation of the monitoring range, determines "NO" in step S112, and executes the program. The process advances to step S114. When the automatic designation of the monitoring range is completed, the control device 47 sets the flag F1 to "1" (step S118), determines "YES" in step S112, and executes the processing in steps S114 and 116. is omitted and the program proceeds to step S120 and thereafter.

Note that the flag F1 is a flag indicating whether or not the automatic designation of the monitoring range has been completed. When the flag F1 is "1", it indicates that the automatic designation of the monitoring range has been completed; When it is "0", it indicates that the automatic designation of the monitoring range has not been completed. Note that the flag F1 is set to "0" when there is an instruction to start machining the workpiece.

Furthermore, in step S116, the control device 47 determines whether automatic designation of the monitoring range has been completed. When the automatic designation of the monitoring range is completed, the control device 47 determines "YES" in step S116, advances the program to step S118, and sets the flag F1 to 1. If the automatic designation of the monitoring range has not been completed, the control device 47 determines "NO" in step S116, returns the program to step S114, and executes the automatic designation of the monitoring range.

In step S114, the control device 47 executes the automatic monitoring range designation subroutine shown in FIG. First, in step S202, the control device 47 automatically sets a temporary monitoring range that is a candidate for the monitoring range. That is, the control device 47 sets a temporary monitoring range for each processing instruction (block) included in the machining program based on the processing instruction type. Specifically, if a block includes a processing instruction, the control device 47 determines that the small processing step by that block (processing block) is within the temporary monitoring range, If a non-processing instruction that is not an instruction is included, it is determined that the process by that block (non-processing block) cannot be within the monitoring range. For example, blocks B1, B5-B7 include processing execution commands (“G1”, “G2”, “G3”, etc.) in the G code, so the control device 47 uses these processing execution commands. It becomes possible to automatically set the machining sub-process corresponding to the block including the block as the temporary monitoring range.

In step S204, the control device 47 acquires load data (processing data) that is linked (associated) with the processing points and ultimately the processing sub-processes from the storage device 47b. Then, in step S206, the control device 47 associates the temporary monitoring range (processing block) automatically set in advance with the processing corresponding data Da. The temporary monitoring range (processing block) is linked (associated) with the processing point, and the processing corresponding data Da is also linked with the processing point. As a result, the control device 47 can associate the temporary monitoring range (processing block) with the processing corresponding data Da via the processing points. In turn, the control device 47 can associate the machining program with the machining data. Thereafter, the control device 47 ends the processing of this subroutine.

(Setting the upper and lower limits of the monitoring range)
The explanation will proceed to step S120 and subsequent steps shown in FIG. That is, when the automatic designation of the monitoring range is completed, the control device 47 sets the upper and lower limits of the designated monitoring range (step S124). That is, the control device 47 automatically sets the upper and lower limits of the monitoring range by machining the workpiece W (workpiece machining) N times and using load data (actual detection data) for N times.

Specifically, the control device 47 performs the first to Nth workpiece machining, stores the load data for each workpiece machining (determined as "NO" in steps S120 and 122, respectively), and stores the load data for each workpiece machining (determined as "NO" in steps S120 and 122, respectively). The upper and lower limit values of the monitoring range are set using the load data (after determining "NO" or "YES" in steps S120 and 122, in step S124). At this time, in step S124, the control device 47 sets an upper limit value and a lower limit value of the monitoring range for each processing point. The maximum value of the load detection values for N processing points can be set as the upper limit value, and the minimum value can be set as the lower limit value.

Further, the control device 47 sets the flag F2 to 1 in step S126. The flag F2 is a flag indicating whether the upper and lower limits of the monitoring range have been set based on N times of load data, and when the flag F2 is "1", it indicates that the upper and lower limits of the monitoring range have been set. , and when the flag F2 is "0", it indicates that the upper and lower limits of the monitoring range have not been set. Note that the flag F2 is set to "0" when there is an instruction to start machining the workpiece.

Note that in step S120, it is determined whether the flag F2 is 1 or not. The control device 47 determines that the flag F2 is "0" from the start of machining the workpiece W until the upper and lower limits of the monitoring range are set, and the determination is "NO" in step S120. When the upper and lower limits of the monitoring range have been set, the control device 47 sets the flag F2 to "1", determines "YES" in step S120, and omits the processes of steps S122 to S126. The program advances to step S128 and subsequent steps.

Further, in step S122, it is determined whether the above-described workpiece machining, machining load detection, and load data storage have been performed N times. After the first workpiece machining is started and before the Nth workpiece machining is completed, the control device 47 determines that the workpiece machining has not been completed N times ("NO" in step S122). ”), the program returns to step S104. When the Nth workpiece machining is completed, the control device 47 determines that the Nth workpiece machining has been completed ("YES" in step S122), and advances the program to step S124.

(Section specification of monitoring range and adjustment of upper and lower limit values by manual operation by worker)
Next, the control device 47 manually specifies a monitoring range (section of the monitoring range (monitoring section)) from the temporary monitoring range that was automatically specified in step S114, and the upper and lower limits of the specified monitoring range. The values (upper and lower limit values automatically set in step S124) are manually adjusted. This allows workers to first specify the monitoring range that requires the monitoring function from within the temporary monitoring range, and then adjust the upper and lower limits of the specified monitoring range through a series of manual operations. becomes. As a result, the monitoring range can be specified and adjusted more easily. Note that the section designation of the monitoring range and the adjustment of the upper and lower limit values may not be performed by continuous operations, but may be performed by separate operations.

(Monitoring range manual specification process)
Specifically, first, the control device 47 manually specifies a monitoring range from among the temporary monitoring ranges automatically specified in step S114 (step S129: specification section (manual specification section)). Specifically, the control device 47 executes the monitoring range manual designation subroutine shown in FIG. 11 in step S129. If there is no manual designation start operation for starting manual designation of the monitoring range, the control device 47 determines "NO" in step S302, and ends the processing of this subroutine. On the other hand, if there is a manual specification start operation, the control device 47 determines "YES" in step S302, and first transfers the associated machining program and machining data to the input/output device 11 in step S206. They are simultaneously displayed on the display panel 11a (display device) (see FIG. 5; step S304).

Note that the manual specification start operation is specifically an operation for displaying processed data on the data display section 110 of the monitoring enablement setting screen 100 (individual enablement setting screen) and displaying blocks on the program display section 200. For example, the manual specification start operation is an operation of displaying the monitoring enable setting screen 100 (individual enable setting screen) shown in FIG. 5 by operating the program display key 130. Note that the manual specification start operation is not limited to the program display key 130, and may be an operation of an operation key for starting manual specification of the monitoring range. Further, the manual specification start operation can be said to be an operation for starting section specification of the monitoring range and adjustment of the upper and lower limit values.

In step S304, the control device 47 transmits the machining program and machining data previously associated in step S206 to an input/output device in order to let the operator determine a monitoring range that requires a monitoring function from among the temporary monitoring ranges. 11 display panels 11a at the same time. Processing data and processing blocks are associated with each other, and when an operator selects any one of the plurality of processing data displayed on the data display section 110 by touching it. In the program display section 200, the machining block associated with the contacted machining corresponding data is displayed in an emphasized manner (highlight display). On the other hand, when the operator performs a selection operation by touching any one of the plurality of machining blocks displayed on the program display section 200, the data display section 110 associates the machining block with the touched machining block. The machining data that has been processed will be highlighted and displayed (highlight display).

If the operator looks at the mutually associated machining corresponding data and machining blocks displayed in this way and thinks that it is necessary to set it as the monitoring range within the temporary monitoring range, the operator can change the temporary monitoring range. Perform the specification operation to specify the monitoring range from among the following. On the other hand, if it is considered that it is not necessary to set the monitoring range among the temporary monitoring ranges, the designation operation for specifying the monitoring range from among the temporary monitoring ranges is not performed.

The specification operation is an operation in which the operator specifies the monitoring range that he or she wants to monitor individually or all at once. Specifically, when specifying them individually, the operator must perform a selection operation to select one or more machining blocks (machining processing instructions) from among the machining blocks (machining processing commands) displayed in the displayed machining program, or A selection operation is performed to select one or more processing compatible data Da from a plurality of processing compatible data Da out of the processed data D that has been processed. This selection operation can be realized by the operator directly touching the corresponding machining block or street machining data Da on the monitoring enablement setting screen 100, or by specifying it with a cursor linked to a mouse or the like. The series of operations described above is an individual designation operation for individually designating the monitoring range.

If the above-mentioned designation operation for the temporary monitoring range has not been performed, the control device 47 determines "NO" in step S306, and ends the processing of this subroutine. On the other hand, if there is a designation operation for the temporary monitoring range, the control device 47 determines "YES" in step S306, and displays the specified temporary monitoring range and processing block in an emphasized manner (highlight display: Step S308). For example, as shown in FIG. 5, block B1, which is a designated processing block, is displayed with hollow characters. Further, in the load monitoring range R8 that corresponds to the specified machining data Da and is associated with the block B1, the range from the monitoring start point to the monitoring end point has a background color different from the background color (for example, black) of other parts. Displayed in color (for example, blue). Note that the cooperative display may be performed using other display methods, for example, the specified temporary monitoring range and processing block may be displayed in a blinking manner.

In step S310, the control device 47 determines whether the operator has performed an enable/disable operation to enable or disable the monitoring function of the temporary monitoring range designated (selected) as described above. . The valid/invalid operation is performed, for example, by turning on the valid/invalid switch key 151 after the monitoring range is specified (selected). That is, when the valid/invalid switch key 151 is turned on (valid operation) when a monitoring range in which the monitoring function is disabled is specified, the monitoring function of that monitoring range is enabled. On the other hand, when the valid/invalid switch key 151 is turned on (invalid operation) when a monitoring range in which the monitoring function is enabled is specified, the monitoring function in that monitoring range is disabled.

If the operator performs a valid operation, the control device 47 determines that it is a "valid operation" in step S310, and in step S312, activates the monitoring function of the specified temporary monitoring range, that is, sets it as the monitoring range. Select and store in the storage device 47b. On the other hand, if the worker performs an invalid operation, the control device 47 determines that it is an "invalid operation" in step S310, and disables the monitoring function of the specified temporary monitoring range in step S314. It is not selected as a range and is stored in the storage device 47b (in other words, it is selected as a non-monitoring range and stored in the storage device 47b). Thereafter, the control device 47 ends this subroutine.

Note that the operator may specify the monitoring range that he or she wants to monitor all at once. In this case, when the operator first operates the program display key 130, the control device 47 displays the monitoring enable setting screen 100 (batch enable setting screen) shown in FIG. In this monitoring enablement setting screen 100, only processed data is displayed on the data display section 110, and no blocks are displayed on the program display section 200. Then, the operator performs a selection operation to select all of the processed data Da from the processed data D. For example, by turning on the all valid key 152, the operator can designate the range (temporary monitoring range) corresponding to all the processing data Da as the monitoring range (all designation). The series of operations described above is a batch designation operation that designates the monitoring range all at once. Incidentally, in order to invalidate the designation of all specified monitoring ranges, it is sufficient to turn on the all invalidation key 153. Furthermore, in this case, the processing in steps S306 and 308 described above may be omitted.

(Adjustment of upper and lower limits of monitoring range)
Next, when the monitoring range manual specification processing (processing of manually specifying the monitoring range in which the monitoring function is enabled) is completed, the control device 47 sets the upper and lower limits of the already set monitoring range according to the operator's adjustment operation. Adjust (step S130: adjustment section). If the operator thinks that it is necessary to adjust the monitoring range, he or she performs an adjustment operation to adjust the monitoring range. Note that if the operator considers that adjustment of the monitoring range is not necessary, the operator performs an operation indicating that adjustment operation is not necessary (adjustment unnecessary operation).

Adjustment operations include selecting the axis that includes the monitoring range that the operator wants to adjust, selecting the monitoring range that the operator wants to adjust, specifying the range that the operator wants to adjust (adjustment range, specified range), and selecting the specified range ( This is an operation for enlarging/reducing the upper limit value of the monitoring range, or enlarging/reducing the lower limit value of the specified range. These operations are performed by operating operation keys (not shown).

If the adjustment of the upper and lower limits of the monitoring ranges has not been completed for all the specified monitoring ranges, the control device 47 determines "NO" in step S132, and returns the program to step S129. When the adjustment of the upper and lower limits of the monitoring ranges has been completed for all specified monitoring ranges, the control device 47 determines "YES" in step S132 and sets the flag F3 to "1" (step S134). After that, the program advances to step S136 and subsequent steps.

The flag F3 is a flag indicating whether or not the section designation and upper/lower limit value adjustment of the monitoring range by manual operation (manual designation/adjustment of the monitoring range) is completed, and when the flag F3 is "1", This indicates that the manual designation/adjustment of the monitoring range has been completed, and when the flag F3 is "0", it indicates that the manual designation/adjustment of the monitoring range has not been completed. Note that the flag F3 is set to "0" when there is an instruction to start machining the workpiece.

Further, in step S128, it is determined whether the flag F3 is 1 or not. In the control device 47, the flag F3 is "0" after the upper and lower limits of the monitoring range are automatically set until the manual designation and adjustment of the monitoring range is completed, and the flag F3 is set to "NO" in step S128. It is determined that When the manual designation and adjustment of the monitoring range is completed, the control device 47 sets the flag F3 to "1", determines "YES" in step S128, and skips the processing of steps S129 to S134 and executes the program. The process proceeds to step S136 and subsequent steps.

In step S136, the control device 47 determines whether the detected load value, which is the detected machining load, is within the upper and lower limits of the monitoring range. If the control device 47 determines that the detected load value is within the upper and lower limits of the monitoring range ("YES" in step S136), the control device 47 returns the program to step S104 and performs steps S104 to S110 described above. A series of processes are executed in accordance with the order of the machining program. If the control device 47 determines that the detected load value is not within the upper and lower limits of the monitoring range (“NO” in step S136), the control device 47 advances the program to step S138 and thereafter, and stops machining the workpiece W. (Step S138) and a warning is issued (Step S140), and then this flowchart ends.

Note that the machining (cutting) of the workpiece W by the above-mentioned machine tool (Dorimill module 30B) can also be controlled according to the flowchart shown in FIG. 9, similarly to the above-mentioned lathe module 30A. In this case, control is performed by the control device 57 instead of the control device 47.

(control devices 47, 57: step S129; input/output devices 47a, 57a).

According to this, the worker can view the machining commands or the machining corresponding data displayed on the input/output devices 47a, 57a while viewing both the machining program and the machining data displayed on the input/output devices 47a, 57a at the same time. By selecting and operating , it becomes possible to specify a necessary monitoring range (monitoring section; monitoring range that the operator considers necessary) out of the monitoring range. As a result, the operator can easily and reliably set the necessary monitoring range (monitoring section).

Furthermore, the monitoring range is automatically set for all the processing instructions constituting the processing program based on the processing instruction type for each processing instruction (step S114).

According to this, it becomes possible to appropriately adjust the upper limit value and/or lower limit value of the necessary monitoring range specified by the operator.

Further, the machining data is displayed on the input/output devices 47a, 57a as a series of data continuously indicating changes in the machining load.
