Abstract: The grinding wheel infeed control method provides a constant infeed rate calculated on the average electrical power consumed by the wheel drive motor in rough grinding an immediately preceding workpart. Each subsequent workpart is rough ground at a constant infeed rate established from the wheel drive motor power consumption of the immediately preceding workpart until the grinding wheel is in need of re-trueing or re-dressing. The first workpart ground after wheel re-trueing or re-dressing is ground at a rough (high) infeed rate which is continuously varied by the machine control computer so as to maintain the electrical power consumed by the grinding wheel drive motor substantially constant at a preset level and from which the constant infeed rate for the second workpart is determined.
