Abstract
A system for controlling motion in machine tools and industrial robots. From the specification of a part to be cut or a path to be followed by a machine tool or a robot, the system calculates, for each axis, for each incremental step along the path, a position command, a time delay between successive position commands, and, optionally, a force command based on a prediction of predicted resistive forces. Calculations are specified for precisely controlling velocity, acceleration, and jerk. The generated data is stored in a memory device and subsequently directed to the machine tool or robot.
