ABSTRACT:
A cylindrical grinder for effecting stock removal from a cam surface on a workpiece comprising apparatus for supporting the workpiece for rotation about a predetermined axis, grinding assembly including a grinding wheel, apparatus for defining a selected velocity profile for each revolution of the workpiece, the velocity profile having a plurality of acceleration/deceleration segments each having first and second radiused end portions each terminating at one end tangential to the constant velocity direction, the defining apparatus including pulse driven stepping motor apparatus which will rotate the workpiece one complete revolution when issued a predetermined number of pulses, and pulse generating apparatus for driving the stepping motor apparatus including an oscillator for generating a continuous train of pulses at a fixed rate or frequency and divide by N apparatus for defining which pulses of the pulse train will be successively issued to the stepping motor apparatus so as to provide a selected velocity to the cam surface.
