Abstract
PURPOSE: To reduce noncutting time with a higher feed speed by discriminating it detecting a load during the cutting operation of an NC machine tool.
CONSTITUTION: A load current of a spindle motor or a Z axis servomotor M is detected with a detector 6 and fed to an input buffer circuit 7. The value of the load current at the start of the command is held in an initial value holding circuit 4 as a value for the time of noncutting. The value is compared with the initial value held by a comparator 5. An overriding setting circuit 8 is set at a maximum value so as to maximize the feed speed. When a cutting load current is detected by the comparator 5, the overriding reaches a level of 100% and is sent to an NC equipment by way of an output circuit 9. Then, the equipment is operated with a command value of a command tape.
