 Multistage Manufacturing Processes of Cylinder Block

Abstract

Abstract:

Abstract： Four types of coordinate systemsare defined for the multistage manufacturing process (MMP) of cylinder blocks. The coupling relationships between datum error, fixture error and tool error areanalyzed.Through the finite element analysis of the cylinder block manufacturing process, the cutting forceinduced deformation displacements of the processed surface are simulated with tool error. The specific characteristic dimension is described by using differential motion vectors (DMV) of multiple featurepoints. The state space model of the stream of variations (SoV) based on the DMV of a single point is extended based on the DMV description by considering the cutting forceinduced deformation displacements. The effectiveness and feasibility of the model are validated by a case study of the B12 cylinder block.

Key words:
