Abstract

PURPOSE: To accarately display the edge position of a new tool, by computing the difference between positional vectors of the edges of new and old tools when the old tool is replaced by the new tool, and adding the differential vector to the positional vector of the old tool.
CONSTITUTION: Positional vector of the edge of the old tool 5 is given by OP1, when a tool table 4 is turned the positional vector of the edge of the new tool 6 is given by OP2, when the tools are changed the positional vector of the edge of the tool is given by OP1=OP1+OP2, if the rotational center is designated by Q, OP1= OP1+(QP2+QP1) since the difference of vector between the positional vectors QP1 and QP2 equals the vector difference between the exsisting positions of the edges. Therefore the differential vectors QP1, QP2 with respect to respective tools are previously obtained and inputted into a tape 11, and when the tool is replaced the differential vector is added to the vector of the edge position of the old tool by a control circuit CPU to display the current position by Rx, Rz.
