Abstract
A method for processing a workpiece with a tool is provided with holding the workpiece, holding the tool, and moving the held tool relative to the held workpiece in accordance with an NC program including an arithmetic expression to calculate a position of the held tool.
Claims6
A method for processing a workpiece with a tool, comprising:
- holding the workpiece;
- holding the tool;
- with an NC program including an arithmetic expression configured to calculate a position of the held tool, wherein the arithmetic expression includes values for correcting errors in a contour of the held tool, wherein the values for correcting the errors in the arithmetic expression are calculated as to one or more processing points of the held tool:
- determining a cut-off frequency from a numerical difference between a radius of a surface to be processed on the held workpiece and a radius of an arc portion of the held tool,
- filtering a curve depicting the errors in the contour of the held tool to remove frequency components from the curve that are higher than the cut-off frequency, and
- reflecting the filtered curve in the arithmetic expression;
- and
- moving the held tool relative to the held workpiece in accordance with the NC program including the arithmetic expression configured to calculate the position of the held tool.

A machine for processing a workpiece with a tool, comprising:
- a holding section configured to hold the workpiece;
- a tool holding section configured to hold the tool;
- a control section including an NC program including an arithmetic expression configured to calculate a position of the held tool, the control section being configured to:
- determine a cut-off frequency from a numerical difference between a radius of a surface to be processed on the held workpiece and a radius of an arc portion of the held tool,
- filter a curve depicting errors in the contour of the held tool to remove frequency components from the curve that are higher than the cut-off frequency, and
- reflect the filtered curve in the arithmetic expression;
- and
- a moving section configured to move the held tool relative to the held workpiece, the moving section being controlled by the control section.
