Abstract
A control system for a crankshaft-milling or grinding machine having a milling carriage movable in a plane perpendicular to the longitudinal axis of the crankshaft to be machined. A pulse-generating rotary transducer coupled to the workpiece spindle supplies pulses to a computer to indicate both rotary speed and angular position, the computer issuing the requisite control data. The computer is fed pictorial or construction-point data concerning crank pins and crank webs of arbitrary configuration, the computer issuing the requisite control data for feed speed and position after it itself has calculated such data, the data being issued with a clocking rate and updated at such clocking rate at a frequency corresponding to the required degree of dimensional accuracy.
