Title:
TOOL PATH GENERATION METHOD, TOOL PATH GENERATION DEVICE, AND MACHINE TOOL CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/117893
Kind Code:
A1
Abstract:
Provided is a tool path generation method for generating a tool path (Tp), along which a workpiece is machined as a tool (T) moves over a tool movement curved surface (So) generated along a work surface of the workpiece. In this method: a scanning policy is set, which is a rule for establishing a path along which the tool is to move over the tool movement curved surface (So); a dividing line (Cd) is disposed on the tool movement curved surface (So); and the location of an intersection of the dividing line and a trajectory of the tool moving over the tool movement curved surface is calculated on the basis of the scanning policy. A tool path is generated, the path being represented by a movement command for curve interpolation using a curve that passes through the location of the intersection.
