摘要： Serving to control at least two pulse-controlled drive means for moving a tool along respective coordinate axes, the control system comprises input means for presenting workpiece data and tool data; an arithmetic unit for processing said workpiece data and tool data presented by said input means and for providing section end point data which are related to said coordinate axes and define section end point positions of said tool on a path along which the tool is to be moved by said drive means; clock means operable to produce clock signals at a plurality of clock frequencies; and interpolating means arranged to receive said section end point data and clock signals and to deliver speed control pulses to each of said drive means to cause said drive means to move said tool between successive ones of said section end point positions along path sections having predetermined configurations. The arithmetic unit and interpolating means are comprised in a computer, which is operable in accordance with a fixed program for delivering direction control signals to each of said drive means and for determining the operation of said arithmetic unit to process said workpiece data and tool data, the operation of said interpolating means to determine the configuration of each of said path sections and the delivery of said speed control pulses to each of said drive means at the frequency of a selected one of said clock signals.
