An Analytical and Experimental Study of Grinding Temperature for Heavy Duty Cam

In order to further study the grinding mechanism and to improve the grinding quality of non-circular cams a mathematical heat transfer model for cam grinding was set up based on the heat transfer theory with reasonable assumptions and simplifications on a heavy duty cam grinding. Internal distributions of temperature, stress, and deformation of the cam were achieved from the cam grinding simulation by ANSYS with calculation and analysis on instantaneous thermal transfer. Results from the simulation truly reflected the heat distribution in the cam grinding. Supported by experiments, the temperature fields from ANSYS were matched by large by what from on line infra red cameras, with an average relative difference about 8.83%. This offers help in solving the problem of cam surface thermal damage and deformation and others during cam grinding.
