Abstract

In line with the advancement of precision and ultra-precision manufacturing, the demand for higher level of accuracy of products is getting utmost importance, especially in the case of miniature products requiring higher dimensional accuracy and surface quality. In addition, due to the requirement of stringent functional qualities, products need to have extreme accuracy to get rid of rejection. To arrive at these targets machined products need to have tolerance-fee dimensions, flawless and nano-level surface finish. Consequently, it becomes necessary to manufacture extreme products having extreme dimensional accuracy to meet extreme functionality. Thus, there arises the necessity to get rid of the possibilities of errors from their sources.  These aims and objectives can be achieved only through; (i) the fabrication of dimensional tolerance-free or at least near-tolerance-free components, (ii) development of machine tools capable of manufacturing such products and (iii) through the development of extreme processes.  An attempt has been made in this study to evaluate the current status of the above-mentioned areas of manufacturing and to propose what needs to be done to arrive at the targets.
