Title: Numerical Travel Control System.

IPC: G05B19/408
Filed: 1967-12-20
Abstract: 1,187,151. Programmed control of machine tool. STARKSTROM-ANLAGENBAU KARLMARX-STADT, VEB. Dec.20, 1967, No.57787/67. Heading G3N. In a numerical travel control system position or feed-rate change values are fed to an internal computer and after computation stored and used by an output mechanism to control relays determining the feed-rate of a drive, and the output mechanism calls up for computation the feed-rate change values corresponding to travel differences. As shown, ring counters Z1, Z2 are controlled by main pulses from a pulse generator, not shown, whereby on complete of a cycle in counter 21, the counter 22 is stepped. The counters Z1, Z2 are connected respectively, to the lines 1-5 and columns 11-14 of a matrix which is inter-connected by AND-elements. The columns 11-14 are allotted to numerical digit values of ascending magnitude and the lines 1-5 to the tool datum position, tool radius, required position, feed-rate change values and actual tool position respectively. The columns are connected through an OR-element 20 to an internal computing device 21, having a store and a subsidiary pulse generator, not shown. In the course of each main pulse two subsidiary pulse trains A, B are generated, each of which comprises an erasing and a writing pulse. The A erasing pulse erases the value present in the internal computer 21 and the A write pulse then sets in the computer the next line digit in the column together the value in a carry store U2-U5. The calculated value is transferred to the computer store. The B erase pulse erases an arithmetic store 22 and the carry store for the next line and the B write pulse transfers the calculated value to the store 22 and the carry output to the next carry store. The main pulse disappears and the subsequent main pulse initiates the calculation of the next line in the column. After the completion of a column the ring-counter Z1 steps on to 1 and the ring-counter Z2 is stepped to the next column. In the main pulse for the final stages of both counters Z1, Z2 an AND-element 25 opens and the output of carry-store U5 reaches a directiondetermining store 27 via an output unit 26. Simultaneously with the input to the direction store 27 the unit 26 steps once and a relay 28 is initiated, causing the tool to move at a 'rapid movement' feed-rate, and open an AND-gate 31 setting in a 'working' feed-rate on line 4a into the calculation. A subsequent change in sign of the signal to direction store 27 at co-incidence initiates the 'working' feed-rate through a relay 29, the closure of a gate 31 and the opening of a gate 32, setting in an'inching'feed-rate on line 4b. A subsequent signal changes initiates a relay 30 for inching and a final signal change to the store 27 stops the travel, since no further feed-rate change position values are called into the calculation.
