Electronic control device for individual drives of machining machines and process for controlling the individual drives

An electronic control device for individual drives of machining machines, particularly of machine tools with a plurality of tool and/or workpiece drive apparatuses, for the machining of workpieces in machining cycles, characterised by

• a counting pulse generator (34) which generates a definite number of counting pulses (Z) during each machining cycle (B);
• a pulse counter (35);
• a memory unit (36) having memories (41-43) which contain a plurality of path information values (h) for each drive apparatus (13, 14, 15, 18, 19, 20);
• and
• a computer unit (37) which is connected to the pulse counter (35) and to the memory unit (36), and which scans the counter state (k) at the pulse counter (35) at equal time intervals (scanning period) and extracts the path information values (h) assigned to the counter state (k) from the memory unit (36) at the scanning instant each time and converts them into control values (s) necessary for machining, which control values are fed as set values to a control circuit (30, 31, 32) for the respective drive apparatus (18, 19, 20).
