Low-stress grinding (LSG) utilizes special combinations of grinding param-
eters that reduce the heat shock and plastic deformation inherent in all
grinding operations (lower infeed and softer grinding wheels). Under these
conditions, excellent dimensional control, ne surface nish, a minimum of
residual stress, and low workpiece distortion are achieved. LSG was found
suitable when low distortion, absence of cracks, ne nish, and high fatigue
strength are needed (Bellow, 1978).
8.2.2 Wheel Wear
Grinding wheels will wear faster than other cutting tools. The grinding-
wheel ratio represents a generally accepted ...
