A high ratio of heats produced during surface grinding
process transfers to a workpiece and can cause various types
of thermal damage to the final product such as the burn
phenomenon, geometric error, residual stress, structure
transformation, and others. These are a measure of the
quality evaluation in the ground surface and should be
limited as a certain range below. The most important
consideration of thermal damages is the geometric
error, which is related to inaccuracy of the final product.
The geometric error is affected not only by a thermal aspect
of the contact zone between workpiece and grinding wheel
but also by a stiffness of the grinding system that
causes some degree of a vertical displacement against
grinding force.
