Abstract
The tendency of heat checks and cracks to form in the workpiece is shown to be strongly dependent upon work speed. The durability of the cutting edges of tools is shown to be affected by the work speed during sharpening. Based on the rubbing-grain hypothesis, the “theory of heat conducton” is applied to the grinding process to show that lower surface temperatures occur when grinding is done at high work-surface speed.
