Precision cylindrical face grinding

The mathematical models and experimental validations of precision cylindric al face grinding using a narrow ring superabrasive wheel are presented. The high pressure seal in diesel engine fuel systems demands the mu m-scale fo rm tolerance specifications and has driven the development of precision fac e grinding using the superabrasive wheel. Two mathematical models were deve loped: one was applied to predict the convex or concave face profile and an other was used to simulate the abrasive trajectories, which become the cros s-hatch grinding marks on the ground face. Cylindrical face grinding experi ments were conducted. Experimental measurements of face profile and abrasiv e trajectories were used to validate the theoretical results. For high-pres sure sealing surfaces, the height of face profile and grinding trajectories were two critical characteristics for design and manufacturing. Two design tools, a linear approximate solution for the profile height and an atlas f or grinding trajectories, were developed to assist the selection of process parameters for the machine setup.
