Simulation of Engine Deck Face Distortion During Fixturing and Milling Operations 2000-01-1287
The surface quality of deck face is a major factor affecting the gasket sealing of an engine block. The deck surface quality is mainly governed by external loads (clamping preload and machining force) during machining process. In machining process development, it is highly desirable to predict the quality of a machined surface. The thrust of this study, then, is an attempt to simulate deck face distortion during fixturing and milling operations using finite element analysis. The compliance of fixture components and dynamic response of the fixture-workpiece system are taken into account in this study. Finally, a production v-type engine block is demonstrated.
