<p>1. A gear shaping machine by the generating process or a hob cutter comprising electronically controlled, separate drives for moving the tool (10) and the workpiece (14) to be machined, said movement being superimposed on a plurality of axes, the drive of the workpiece being readjusted in accordance with the actual position values of the tool, characterized in that a modular control computer system integrated into the machine and comprising a plurality of processors (MPST) is provided that consists of at least one processor (18) for organizing the access to the data bus (BUS), a processor (22) for coupling the rolling movement between the shaping wheel (10) and the work wheel (14), said processor readjusting the rotating position and speed of the clamping table (12) at least every 5 ms to the actual position of the shaping spindle, and a processor (24) for regulating the linear axes and other additional axes as well as the radial feed motion and run-off control of the lifting ram, the access of the processor (22) for the rolling coupling to the actual position values of the relative angular positions of the shaping and work wheels at predetermined time intervals being ensured in that the access to the data bus (BUS) is requested with a lead time which is longer than the longest time during which the data bus is used by the other processors (18, 24).</p> |
