A mathematical model of heat transfer in steel parts 
in force grinding is considered. The model allows one to determine 
parameters of grinding at which the layer of steel of the given  thickness 
is heated to the temperatures of quenching. The main laws governing 
the changes in the temperature of the part being ground are presented. 
The situation of the appearance of cleavages and melting of the edge 
of a wedge-like body in grinding and sharpening is analyzed.
