Title:
NUMERICAL CONTROL DEVICE, MACHINE TOOL, NUMERICAL CONTROL METHOD, AND NUMERICAL CONTROL PROGRAM
Document Type and Number:
WIPO Patent Application WO/2024/057910
Kind Code:
A1
Abstract:
Provided are a numerical control device, a machine tool, a numerical control method, and a numerical control program which contribute in achieving an advantage that an increase in moving time of a moving part is suppressed while suppressing the amount of computation for calculating a speed curve prior to acceleration/deceleration processing. A CPU of this numerical control device reads the current block Nnow and a prefetch block and determines a target block Nd and a target speed Vd at a command point for the target block Nd. The CPU calculates a first rising speed V1 at the position where tip acceleration becomes zero from the current tip acceleration. The CPU calculates a reverse interpolation point Prev. Every time the reverse interpolation point Prev is calculated, the CPU calculates a second rising speed V2 at the position where the tip acceleration becomes zero from the tip acceleration at the reverse interpolation point Prev.
