Abstract

PURPOSE:To allow the machining with the precision of sub-micron or less by detecting the movement in the direction rectangular to the table sliding direction of a support bed with a position detecting light receiving element and varying the voltage applied to a piezoelectric element in response to the detection quantity. CONSTITUTION:Laser rays R from the laser 6 are first radiated to the center of a photo-diode 5, and an air slide 1 is driven at 0.33mm/sec. If a support bed 3 is even slightly moved in the Y direction in relation to the air slide 1 at this time, the laser rays R are biased from the original center of the photo-diode 5, light quantities entering the right and left portions of the light receiving section of the photo-diode differ, a current is generated by detecting the difference, and the signal by this current is inputted to a control block 8. The voltage is applied to a piezoelectric element 7 so that the laser rays R are returned to the center of the photo-diode 5, and the applied voltage is made zero when the laser rays are returned to the center. A cutting tool 4 fixed on the support bed 3 is moved in the X direction regardless of the movement of a movable table 2 in the Y direction, and the precision of the machining face is improved.
