sequentially measuring whether the workpiece of each clamping position is clamped in place or not through the probe, when the measurement result is negative, alarming, correspondingly recording the clamping position as a first operation, and continuously measuring the next clamping position; when the measurement result is yes, correspondingly recording the clamping position as a second operation, and continuing to measure the next clamping position until all the clamping positions are completely measured; and performing skipping operation on the workpieces clamped by the clamping positions recorded as the first operation, and sequentially performing machining operation on the workpieces clamped by the clamping positions recorded as the second operation until all the workpieces clamped by the clamping positions recorded as the second operation are completely machined.
10. The process of claim 9, wherein: after all the clamping positions are measured, the method further comprises the following steps:
detecting the cutter through a cutter detection device, judging whether the cutter is normal or not, and alarming and prompting to replace the cutter when the cutter is judged to be broken; when the cutter is judged to be normal, normal skipping is carried out; the cutter checking device feeds back the judgment result to the system, the system receives the information fed back by the cutter checking device and records the service life of the cutter, after the cutter is replaced, the system clears the recorded value of the service life of the cutter and records the service life of the cutter again according to the measurement result of the probe; and when the cutter is judged to be normal, the system carries out accumulated record on the service life of the cutter according to the measurement result of the probe.
