1. A method of grinding a workpiece with diverse grindability characteristics, comprising:
- (a) interfacing a grinding wheel with a workpiece;
(b) sensing the interface force between the wheel and the workpiece;
(c) generating a signal whose magnitude varies as a function of the sensed force;
(d) utilizing the generated signal to increase the interface force to a predetermined level in response to an increase in sensed force; and
(e) utilizing the generated signal to decrease the interface force to a predetermined level in response to a decrease in sensed force.

Abstract
A method and apparatus for controlling the infeed of a grinding machine senses the interface force between a grinding wheel and a workpiece to control infeed for grinding a workpiece with diverse grindability characteristics. The infeed is increased in response to an increase in the sensed force until the interface force reaches a predetermined level; while the interface force is decreased to a predetermined level in response to a decrease in the sensed force.

2. A grinding machine for grinding workpieces with diverse grindability characteristics, comprising:
-
(a) a base; (b) a grinding wheel rotably mounted upon said base; (c) a workpiece support for supporting a workpiece with diverse grindability characteristics; (d) means for effectuating relative infeed movement between said grinding wheel and said workpiece support; (e) means for generating a signal whose magnitude varies as a function of the interface force between said grinding wheel and a workpiece supported in said workpiece support; (f) first means utilizing said generated signal for increasing the infeed in response to an increase in said sensed force, said first means increasing the infeed until the interface force reaches a predetermined level; and (g) second means utilizing said generated signal for decreasing the infeed in response to a decrease in said sensed force, said means decreasing the infeed until the interface force reaches a predetermined level. - View Dependent Claims (3)
