Abstract
A control command is provided to a control computer, by which a workpiece can be machined by a machine tool over a predetermined total height and a predetermined contiguous region by cutting, in particular by turning with a lathe. The control computer automatically determines, based on the control command, a number of travel paths, based on which the workpiece is machined in the predetermined region over a partial height until reaching the total height. The control computer determines the travel paths so that the partial height is varied.
Claims12
A computer-aided control method for a machine tool adapted for machining a workpiece by cutting, in particular by lathe turning, over a predetermined region and a total height, the method comprising the steps of:
- providing a control command to a control computer;
- and
- having the control computer, based on the control command, to automatically determine a plurality of travel paths of the machine tool, whereby the workpiece is machined over a partial height of the workpiece, with the partial height being varied during at least one of the plurality of travel paths when the workpiece is machined by the plurality of travel movements of the machine tool, wherein the partial height varies between a minimum value and a maximum value and the ratio of the minimum value to the maximum value is between 0.5 and 0.9.
A computer program product executing on a control computer for controlling a machine tool adapted for machining a workpiece by cutting, in particular by lathe turning, over a predetermined region and a total height, the computer program product comprising computer instructions for:
- providing a control command to the control computer;
- and
- instructing the control computer, based on the control command, to automatically determine a plurality of travel paths of the machine tool, whereby the workpiece is machined over a partial height of the workpiece, with the partial height being varied during at least one of the plurality of travel movements when the workpiece is machined by the plurality of travel paths of the machine tool, wherein the partial height varies between a minimum value and a maximum value and the ratio of the minimum value to the maximum value is between 0.5 and 0.9.
A control computer for controlling a machine tool adapted far machining a workpiece by cutting, in particular by lathe turning, over a predetermined region and a total height, the control computer comprising:
- means for providing a control command to a control computer;
- and
- means for automatically determining, based on the control command, a plurality of travel movements of the machine tool, whereby the workpiece is machined over a partial height of the workpiece, with the partial height being varied during at least one of the plurality of travel paths when the workpiece is machined by the plurality of travel paths of the machine tool, wherein the partial height varies between a minimum value and a maximum value and the ratio of the minimum value to the maximum value is between 0.5 and 0.9.
