Title:
MACHINING RESULT EVALUATION DEVICE, MACHINING RESULT EVALUATION METHOD, MACHINING CONDITION DETERMINATION DEVICE, AND MACHINING CONDITION DETERMINATION METHOD
Document Type and Number:
WIPO Patent Application WO/2023/223471
Kind Code:
A1
Abstract:
A machining result evaluation device (1) that evaluates a machining result of machining performed by a machine tool (4) comprises: a numerical control simulation unit (12) that simulates an operation of a numerical control device (2) for controlling a servo control device (3) and outputs a position command to a drive shaft of the machine tool; a servo control simulation unit (13) that simulates an operation of the servo control device on the basis of the position command and outputs a torque command to the drive shaft; a drive shaft simulation unit (14) that simulates an operation of the drive shaft on the basis of the torque command; and a machining result evaluation unit (15) that evaluates the machining result on the basis of information corresponding to the operation of the drive shaft. The drive shaft simulation unit outputs position information indicating the position of the drive shaft to the servo control simulation unit. The servo control simulation unit uses the position information to simulate feedback control applied to the drive shaft simulation unit. The machining result evaluation unit evaluates the machining result obtained when the feedback control applied to the drive shaft simulation unit is simulated.
