Pulse control method and system using multiplier

摘要

A method and system for controlling pulse-driven actuators on multidimensional coordinates includes a cutting tool connected to the actuators of a machine tool. The cutting tool is controlled with a specified path and a specified velocity by controlling the output pulses of a multiplier. Data on the coordinates of a plurality of points including points A and B on the specified path and on the specified velocity F is received along with a command indicating an interpolation type. A linear interpolation is performed by a straight line between the point A and the point B, and the interpolated straight line is divided into minute lengths DELTA L and a minute length DELTA La correspondingly to a minute time DELTA T. DELTA T is changed by sending either a first control signal for keeping the specified velocity F corresponding to the minute length DELTA L or a second control signal for keeping the specified velocity F corresponding to the minute length DELTA La to a pulse oscillator for supplying pulses to the multiplier. If the selection of the control signals is appropriate, the cutting tool can keep the specified velocity F when it moves on either portion of DELTA L or DELTA La.
