PURPOSE:To improve the workability considerably, by rewriting speed data in a memory immediately when a speed rewrite command switch is turned on in the state where an override switch is turned on. CONSTITUTION:If the worker depresses a speed rewrite command switch 7 for the purpose of using an overriding feed speed for the next work when a feed driving motor 4 is driven in this feed speed, a microprocessor 9 generates a rewrite permission signal muP2 at the moment of cycle switching in a period other than the period where a preliminarily programmed fixed speed is set, and the signal muP2, an override effective signal OVS, and a speed rewrite command signal PB are inputted to an AND circuit 23. The circuit 23 rewrites contents of a designated address in a table 8b of a memory 8 with speed data stored in a register 22, namely, overriding speed data. |
