Abstract
<p>Workpiece rigidity during end-milling processes decreases monotonously. Reduction rates of the rigidity become large when the end-milling operations have large cutting stock such as carve out machining. It becomes popular to utilize side-face clamping methods because of large accessibility of cutting tools. However, workpiece rigidities directly affect to clamping force and workpiece deformation when workpieces are clamped with side-face clamping method. This research deals with transitional workpiece deformations considering workpiece rigidity reduction. At first, measured results of clamping force reduction during machining operations are investigated. Secondly, measured workpiece profiles during machining operations are investigated. Finally, FEM analysis of workpiece deformation considering workpiece change is discussed. From the results of the evaluation, it becomes clear that it is necessary to consider the influence of transitional workpiece rigidity to achieve reliable estimation of machining accuracy.</p>
