Modeling of Workpiece Location Error Due to Fixture Geometric Error and Fixture-Workpiece Compliance

Several fixture-related error sources contribute to workpiece location error in a machining system. Inaccurate part placement in the fixture relative to the cutting tool, for example, can negatively affect the quality of the part. In this paper, the following major sources of error are considered: fixture geometric error and elastic deformation of the fixture and workpiece due to fixturing forces. The workpiece location error is predicted by...
