Abstract

PURPOSE: To provide a method for controlling the feed rate in a machine tool capable of shortening the time for deciding the position of tool as well as the cycle time for processing the work without increasing the risk to cause mechanical damage of main shaft or the like.
CONSTITUTION: If the information of feed instruction is stored in F register 27, this information of feed rate instruction is supplied to an instruction voltage generator circuit 31, and a rate instruction voltage FCV corresponding to the feed rate instruction is developed as an output from the instruction voltage generator circuit 31. Then, this voltage FCV is converted into an instruction pulse CP by means of anFV converter 32, and the instruction pulse CP of a frequency corresponding to the dimension of FCV is supplied to a gate circuit 33 and a movement quantity counter 34. The gate circuit effects a gate switching based on the information of the moving shaft as developed from a shaft register 29 and the information of the movement direction as developed from a direction register 30
