Title:
WORKPIECE MACHINING METHOD AND WORKPIECE MACHINING DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/230568
Kind Code:
A1
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.
