Abstract

A workpiece machining device (1) is provided with a positional displacement correction unit (331) that detects the positional displacement between a real contour line (P2) of a radius end mill (3) and an ideal contour line (P1) and corrects the positional displacement of the radius end mill (3). The positional displacement correction unit (331) calculates a first correction value for aligning the center of a first circular-arc portion forming a circular-arc shape in a corner portion of the ideal contour line (P1) with the center of a second circular-arc portion forming a circular-arc shape in a corner portion of the real contour line (P2) in a plane orthogonal to the rotation axis, and corrects a machining point of the radius end mill (3) using the first correction value.

Description

technical field [0001] The invention relates to a workpiece processing method and a workpiece processing device. Background technique [0002] Conventionally, a workpiece processing apparatus has been used that uses an NC program to relatively move an end mill to a workpiece (material to be processed), and to rotate the end mill to perform cutting processing on the workpiece. [0003] In such a machining device, the end mill is clamped and fixed to a tool holding portion such as a spindle, moved relative to a workpiece, and then cutting is performed. Therefore, a positional shift occurs when the end mill is fixed to the tool holding portion due to poor clamping or the like. In addition, initial shape errors may occur in the end mill. In such a case, there is a problem that the end mill cannot be moved to an accurate cutting position with respect to the workpiece, and high-precision cutting cannot be performed. [0004] In addition, Patent Document 1 discloses that when ma...
