Nonconventional Sources of Movement Used to Obtain High Level Precision Manufacturing

Abstract:

Since the beginning of industrial era it was clear that the goal of perfect machine is far away. Things become more complicated as the tool machinery branch developed in quite a fast way so things as using full production capacity of a machine or working with adaptive control become normal and frequent. Reaching a good precision in manufacturing was realized by strengthening the structure , with related weight growth and use of more material both generating supplementary costs. Probably the best idea was to create a structure not so rigid , that means lighter ,a structure predictable in the way it works that means predictable deformation and their direction. The big advantage of the idea is that knowing the deformation we can take corrective actions so that the final precision at the edge of the cutting tool becomes very high. The corrective action consists in a very fine and very fast movement that composed with the structure deformations makes a great precision. The solution it self-generated a new challenge consisting in the need for almost instant movement , the source of which was not conventional. The authors are proposing a “magnetostrictive” engine as a new way of generating precise correction movements.
