Abstract

PURPOSE: For improving accuracy, to control the position of a tool in accordance with the output of the computation that is made as to the compensation for the wear loss on the basis of the boundary wear loss at the distance corresponding to 1/2 of feed distance per revolution backward of the tip of said tool, of said blade portion.
CONSTITUTION: A detector 13 is fixedly provided to detect the wear loss of the blade tip of the tool 10 fitted on a tool rest 9 and a relative operator circuit 19 is furnished to perform operation of the boundary wear loss (B0-B1) at the distance corresponding to 1/2 of feed distance per revolution backward of the tip in the feed direction of said tool 10 on the basis of the output from said detector 13. Further, a tool compensating circuit 22 is provided to perform operation of the compensation of said tool 10 on the basis of the output from said relative operator circuit 19, and a numerical controller 11 to control the position of said tool 10 in accordance with the output of said compensating circuit 22. A value of surface roughness (A1-B1) from said relative operator circuit 19 is compared with the setting thereof by a judging circuit 23, and a machine tool 21 is operated in accordance with the output of said controller 11.
