Title:
WORKPIECE MACHINING METHOD
Document Type and Number:
WIPO Patent Application WO/2021/149638
Kind Code:
A1
Abstract:
The purpose of the present invention is to improve the machined-surface quality of a curved surface of a workpiece without reducing the machining speed when the curved surface is subjected to removal machining. Provided is a workpiece machining method in which a rotating table on which a workpiece is placed and a tool are relatively moved along two linear movement axes orthogonal to each other, the workpiece is rotated about each of a first turning axis and a second turning axis orthogonal to each other by the rotating table, and at least one curved surface of a protruding curved surface and a recessed curved surface is subjected to removal machining. The method includes: disposing the first turning axis so as to be parallel to a first linear movement axis of the two linear movement axes, the motor load during linear movement in the first linear movement axis being relatively small; disposing the second turning axis on a plane perpendicular to the first linear movement axis; and subjecting the curved surface to removal machining along the direction of curvature while moving the workpiece along the first linear movement axis and rotating the workpiece about the second turning axis.
