Study of Clamping System Plasticity for Reaming Tools

Reaming is finishing technology and its main purpose is to obtain required dimension of the hole and also to improve quality of machined surface, geometric deviations of shape and position. This article deals with problem of tools centering for manufacturing of precise holes by reaming. The goal of this article is verification of new tool system design with defined rigidity, resp. flexibility of clamped tool due to element, which joins tool with a machine tool. The tool system behaviour under the certain type of load is done by FEM analysis. For these analyses are used computing systems Autodesk Nastran In-CAD and Siemens NX 11.0. FEM analyses are verified on the real tool prototype
