Abstract

1391557 Grinding machines R D FERRERA 19 Dec 1972 [24 May 1972] 58564/72 Heading B3D [Also in Divisions G3 and H3] The slide 38 of a grinding machine is reciprocated at high frequency and positioned by hydraulic actuator 34 supplied from pump 10 through a proportional electromagnetically operated valve 20. The slide movement is detected by position transducer TP and velocity transducer TV and the resulting signals are compared with signals representing desired position and velocity supplied from generator 56. In the comparator stages 52, Fig. 2 (not shown), the position signals are initially compared and the error signal added to the velocity signals to provide a control signal for electromagnet 21. The signal generator 56, Fig. 3 (not shown), includes an oscillator consisting of two integrating stages separated by an inversion stage which includes a Zener diode to limit its output. The overall feedback signal can be varied to alter the oscillator frequency and a D.C. signal representing mean position is added to provide the positional signal on line 58. The signal on line 60 is taken from the limited stage output and thus represents velocity.
