Abstract

PURPOSE: To achieve high reliability by providing a means to obtain warning and stop signals of machines by the bias ratio of the average values, estimated defective rate of finished dimensions, etc. from the measured datas of multiple number of machined items through a post-process mechanism.
CONSTITUTION: Warning and stopping signals by number of defective items in dimensions, FB signals by bias ratio of the average calues of finished dimensions of acceptable items, and warning and stopping signals by the defective rate of finished dimensions estimated from the number of acceted items are obtained from the measured datas of multiple number of machined items through a post-process mechanism. Machine tools under continuous machining operation are controlled by these signals.
