Abstract

PURPOSE:To prevent the malfunction of a numerical control system, by providing a means to check the operation of each part of a machine tool. CONSTITUTION:A numerical controller NC contains a control part CNT, a monitor memory MNM and a monitor circuit MNT. The part CNT carries out an ordinary numerical control process as well as the writing/reading of the monitor data to the memory MNM plus the control of the circut MNT. The memory MNM stores the monitor data read out of an NC tape TP based on the control of the part CNT and then delivers the data to a comparator CMP. The circuit MNT contains a memory SNM to store the outputs of the comparator CMP plus sensors SNS and PSNS. The comparator CMP compares the proper value of the prescribed state or physical quantity stored in the memory MNM with the sensor output stored in the memory SNM and then delivers an alarm when the difference exceeds the range of allowance.
