Title:
MACHINING PROGRAM CREATION METHOD, WORKPIECE MACHINING METHOD, AND MACHINE TOOL CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/149639
Kind Code:
A1
Abstract:
In the high-efficiency machining of blade parts according to the present invention, there is no reversal of the operating direction of a rotating shaft, and a high-quality machined surface can be obtained rapidly. A machining program is created for a workpiece such that: when a part having a convex curved surface and a concave curved surface, with a pair of edge portions as a boundary, is removal-machined, a virtual convex curve, the curvature of which is not inverted with respect to the convex curved surface, with the curves of the pair of edges as the tangent line, is set for the concave curved surface; a drive surface, for defining tool orientation without curvature inversion, is created by using the virtual convex curve, the convex curve set on the convex curved surface, and the convex curves set on the pair of edges; and a tool axis direction during removal machining is set on the basis of the normal direction of the drive surface for tool orientation definition.
