High performance cutting for ultra-precision machining

International Journal of Nanomanufacturing (IJNM), Vol. 11, No. 5/6, 2015

Abstract: This keynote paper will present new approaches for high performance ultra-precision machining that are developed to overcome typical shortcomings of the currently applied machining process. Firstly, ultra-precision machining is compared to conventional machining and approaches commonly used in the latter one are evaluated regarding their applicability for ultra-precision machining. Secondly, results for applying high speed spindles will be demonstrated and their effect on the acting process forces will be discussed. The use of high speed spindles in ultra-precision machining, however, increases the need for faster and more precise balancing procedures. Here, new concepts for expanding the sensitivity of unbalance measurements by deliberately reducing the stiffness of the spindle mounting are presented.
