Abstract
In a moving apparatus of an arm for a tool edge sensor, the arm can be moved between a housing position which does not obstruct a processing work and a detecting position projected from the housing position. The apparatus is provided with a detecting sensor at a forward end of the arm, a moving device for moving the arm between the housing position and the detecting position, end a positioning device formed of at least six-point contacts arranged separately for three-dimensionally restricting the arm at the detecting position. When the arm is moved between the housing position and a position right before the detecting position, it is moved by the moving device, and at the detecting position of the arm, the arm is released from the moving device and positioned only by the positioning device. Since a positioning error due to the moving device at the time of positioning the detecting position does not occur, the arm can be positioned extremely accurately.
