Abstract
In conventional chucking-system, workpieces such as thin-walled components and low-rigidity parts. have been deformed by chucking-force. And they could not be chucked by the magnetic property of a workpiece. The purpose of this study is to develop a new chucking system, in which the chucking force does not act on the workpiece directly. In the new chucking system, the workpiece can be chucked regardless of magnetic property of the workpiece. The characteristics in which the ice adsorbs the thing is applied. A thermoelectric element is used in order to cool the chucking plate. The high temperature side of the thermoelectric element is radiated by the compressed air. This new chucking system can be used in anywhere, if there is the compressed air. In this study, a design manual for an air-cooling chuck system is proposed, and the validity of the design manual is examined on a basic design by FEM. The performances of the air-cooling chuck are verified by temperature characteristic, adsorption force and cutting test. The test results verify the effectiveness of the proposed systems for practical application.
