Abstract

A process and device for computer-aided adaptation of an application program for a machine tool is described. A sequence of control commands for feed axes of the machine tool defines a contour to be traveled by a tool relative to a workpiece. Based on the sequence of control commands, a computer determines sequential instructions for a round axle of the machine tool to track the contour and determines if, and possibly at which locations, the contour has angular or curvature discontinuities. When such angular or curvature discontinuities occur, the computer determines sequential instructions, so that the round axle begins to start accelerating before the angle or curvature discontinuities occurs, and the acceleration of the round axle terminates only after the angle or curvature discontinuity has ended.
