Title:
NUMERICAL CONTROL DEVICE AND CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2022/024975
Kind Code:
A1
Abstract:
The purpose of the present invention is to shorten the machining path and shorten the cycle time in turning In the present invention, a numerical control device comprises an NC command decoding unit for decoding a command of a machining program, and a tool information storage/generation unit for generating geometric information for a tool. The NC command decoding unit is provided with: a cut amount decoding unit for decoding the cut amount for rough machining from the command, a machining shape generation unit for generating a finishing shape from the command; a machining pathway generation unit for generating a path for rough machining on the basis of the cut amount and the finishing shape; a tool direction provisional determining unit for provisionally determining the direction of the tool from the geometric information and the round-up path and the cut of the path for rough machining; a path joining assessment unit for assessing whether or not to omit a round-up operation from the round-up path and the cut and the provisionally determined direction of the tool; a machining path joining unit for generating a new path for directly moving to the end point of the next operation after the round-up operation if the round-up operation is to be omitted; and a tool direction determining unit for determining the direction of the tool at each machining shape change point on a path for rough machining including the new path.
