A force-controlled clamping element for intelligent fixturing

摘要

This paper deals with the design of a force-controlled clamping element to be applied for intelligent fixturing with the aim to minimise workpiece deformation and distortion under a machining operation. An electro-mechanically controlled clamp isdesigned, fabricated and tested. Test results have shown that the designed-system is capable of controlling clamping force with an accuracy of +/-1 N over the full range of 700 N with rather fast response time of 200 msec.
