Title:
METHOD AND DEVICE FOR GENERATING TOOL PATHS
Document Type and Number:
WIPO Patent Application WO/2019/167650
Kind Code:
A1
Abstract:
This method comprises a step for performing machine learning and a step for generating a new tool path. The step for performing machine learning includes, for each of a plurality of known workpieces: acquiring shape data; acquiring geometric information for each of a plurality of machining faces; acquiring a tool path pattern selected for each of the plurality of machining faces from among a plurality of tool path patterns; and performing machine learning by using the geometric data for the plurality of known workpieces and the tool path patterns wherein the input is the geometric information for the machining faces and the output is the tool path pattern for the machining faces. The step for generating a new tool path includes: acquiring shape data for the workpiece to be machined; acquiring geometric information for each of the plurality of machining faces of the workpiece to be machined; and generating a tool path pattern for each of the plurality of machining faces on the workpiece to be machined on the basis of the results of the machine learning using the geometric information of the workpiece to be machined.
