Abstract:
1. A method for processing a workpiece in which a tool smaller than the workpiece is caused to scan the workpiece, the method comprising the steps of: dwelling a tool on a dummy work for a predetermined time to process the dummy work; measuring the dummy work to determine a unit removal shape; causing the tool to scan the dummy work, and processing the dummy work while continuously changing a dwell time of the tool so that the dwell time is a linear function with respect to a scanning position of the tool; measuring a change of a depth or volume of a removal shape processed in the dummy work, to thereby determine a removal rate corresponding to a continuous change of the dwell time of the tool; determining a tentative dwell time to dwell the tool at respective processed points from a target removal shape of the workpiece and the unit removal shape; determining the removal rate corresponding to the tentative dwell time at the respective processed points; determining a true dwell time at the respective processed points from the removal rate at the respective processed points; and dwelling the tool for the true dwell time at the respective processed points to process the workpiece.
