Title: Digital indicator for feed amount of machine tool and the like
Inventor: NAKAOKI TOORU
IPC: G01D5/245
Filed: 1980-03-22
Abstract: PURPOSE:To enable correct indication of a feed amount of a machine tool in prevention from influence due to backlash, by a method wherein, through the detection of starting of a moving craddle of a machine tool through a feed screw, an input gate of a turning encoder pulse to a reversible counter is controlled. CONSTITUTION:A feed stand 10 reflects an ultrasonic pulse sent from an ultrasonic oscillator 38, and a receiver 40 receives the pulse. A hold-comparison circuit 42 compares a wave-receiving distance and detects a start of an actual movement of the stand 10 through changes in a wave-receiving distance to open a gate circuit 46. This causes up- or down-computation of an encoder pulse, which is outputted by a retary encoder 36 providing with an encoder plate rotating in synchronism with the rotation of a feed screw and is generated corresponding to the rotation of the feed screw, through application of the encode pulse to a reverse circuit 48 via a circuit 46. Thus, a correct feed amount of a machine tool, prevented from influence due to a backlash, is indicated in a digital manner in an indicator 50.
