A method of controlling the movement of a processing head of a machine tool includes monitoring the position of the processing head along a first coordinate direction, monitoring the movement of the processing head along a second coordinate direction different from the first coordinate direction, and limiting the acceleration or the change in acceleration of the processing head along the second coordinate direction to a value below a predetermined maximum value, wherein the predetermined maximum value depends on the position of the processing head along the first coordinate direction.

Machine tool acceleration

A tool for machining workpieces by motion of the machining tool relative to the workpiece has a support extending in the X-axis over a work support table and movable in the Y-axis. A machining tool housing is movable on the support in the Y-axis. A portion of the housing containing the machining tool is movable with respect to the mounted portion in the Y-axis within a limited range of motion. A computer control effects operation of drive motors to move the housing along the support and the support along the machining tool table to machine a workpiece supported on said worktable in X and Y axes, and the computer control can also effect operation of another drive motor to rapidly move of the housing portion and machining tool in the Y-axis when the desired length of motion in the Y-axis is within its range of motion.

Laser cutting machine with two Y-axis drives

A tool for machining workpieces by motion of the machining tool relative to the workpiece in mutually perpendicular X-Y axes has a support extending in one axis over a work support table and movable in the other axis. A machining tool housing is movable on the support in the other axis. A portion of the housing containing the machining tool is movable with respect to the mounted portion in the other axis within a limited range of motion. A computer control effects operation of drive motors to move the housing along the support and the support along the machining tool table to machine a workpiece supported on said worktable in X and Y axes, and the computer control can also effect operation of another drive motor to rapidly move of the housing portion and machining tool in the other axis when the desired length of motion in the other axis is within its range of motion.
