Numerical control system and numerical control device

Abstract

A technique is provided to prevent the robot's movement speed from locally slowing down. The numerical control device 2 includes: a block information generation unit 15 that generates block information containing a block number and a command speed, wherein the block number corresponds to a robot control command included in the numerical control program, and the command speed corresponds to the robot control command; a command modification unit 25 that generates a notification to change the command speed based on the block information and the actual movement speed of the robot 30 obtained in advance corresponding to the block information; and a command generation unit 14 that generates a robot command signal indicating that the command speed has been changed based on the robot control command and the notification from the command modification unit 25.
