In precision abrasive machining, it is important to control process va
riables such as the material removal rate, normal force and power inpu
t, as these factors influence surface finish, dimensional precision, a
nd material damage. In this research, a linear grinding process model,
with enhancements over past models, is developed relating normal forc
e to material removal rates. Two experimental procedures for the deter
mination of the grinding model's parameters are presented. Simulations
are performed to validate the grinding model. The determined model is
found to be a valid representation of she grinding process that shoul
d prove useful in adaptive control with realtime parameter estimation.
