Abstract
Micro-parts are often very fragile rendering conventional, mechanical work-holding
fixtures unsuitable for them since they exert large straining forces. Furthermore, macroworkholding
devices occupy a large space which impedes high precision required in micromilling.
Although some micro-clamping fixtures exist, they are limited to specific part
shapes and in most cases expensive to manufacture. Hence this paper focuses on the
application of adhesive forces namely electrostatic, surface tension and van-der-Waals
forces; in work-holding strategies for micro-milling operations. An analysis is given as to
their applicability with reference to micro-milling cutting forces.
