Abstract

PURPOSE:To elevate the processing accuracy by continuously correcting an error caused by the mechanical system, by means of a moving command pulse, and an error extent of the prescribed extend of the movement. CONSTITUTION:A moving pulse toward the table 19 from the operation part 1 is counted by the counter 3. Each extent of error is read out by said output from the storage device 4 which stores in advance the error extent of position at every prescribed extent of the movement from the reference point, and an interplating pulse is prepared by the interplator DDA8. Subsequently, the interpolating pulse is inserted into the moving command pulse, and it is provided to the resolver 11. In this way, an error caused by the mechanical system, for instance, a pitch error of the leading screw by which the table 19 is moved can be corrected continuously, therefore the processing accuracy of a machine tool can be elevated.
