CONTRIBUTION TO ESTABLISH THE OPTIMAL GRINDING WHEEL EXTERNAL DIAMETER WHEN PLAIN CAMS CONTOUR IS GRINDED

摘要

Grinding is the machining operation which has the capability to remove the machining allowance prescribed for finishing plain cams contour after final heat treatment, in such way to obtain a low roughness value and high contact surface. If the grinding wheel diameter is right established then high precision for cam profile will be obtained, without affecting superficial layer prescribed physico-mechanical properties. Also, machining time will be reduced obtaining in such way economical advantages.
