Title: Tool compensating device for the computerized numerically controlled machine tool

Abstract: An apparatus for sensing a position of a cutting tool in a computer numerical controlled machine tool is provided including an arm supporting and moving a sensor that cooperates with the cutting tool. Also provided is a housing including a gear assembly and a driving motor for moving the arm, and a stopper for defining an operating position of the arm. The driving motor supplies rotation force to the gear assembly so as to pivot the arm against the stopper and then apply force to an elastic member. When the driving motor is stopped, the elastic member applies a force, through the gear assembly, urging the arm against the stopper in the operating position.
