Title:
NUMERICAL CONTROL DEVICE, NUMERICAL CONTROL SYSTEM, PROGRAM, AND NUMERICAL CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2022/092115
Kind Code:
A1
Abstract:
The present invention provides a numerical control device, a numerical control system, a program, and a numerical control method which can prevent the influence of noise in distance measurement. This numerical control device comprises a distance control unit, a filter unit, a determination unit, and a setting unit. The distance control unit controls the distance between a first object and a second object to be close to a target distance. The filter unit filters a signal indicating the distance. The determination unit determines, on the basis of the target distance, a time constant obtained from the relationship between the distance and an output signal from a distance sensor that measures the distance. The setting unit sets a time constant of the filter to the time constant determined by the determination unit.
