Title:
CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/269819
Kind Code:
A9
Abstract:
This machine control device comprises an actuator that produces a thrust force, detects the thrust force of the actuator, acquires the temperature, calculates a threshold value that decreases monotonically with respect to the temperature, compares the thrust force of the actuator with the threshold value, and detects abutment when the thrust force exceeds the threshold value. This machine control device comprises an actuator that produces a thrust force, acquires the temperature, calculates a thrust force limit value that decreases monotonically with respect to the temperature, limits the thrust force of the actuator with the thrust force limit value as an upper limit, detects the speed of a part driven by the thrust force of the actuator, and detects abutment when the part has stopped.
