Abstract: A positioning strategy is presented to minimize the error
range based on one parameter envelope theory for flank milling
undevelopable ruled surfaces with cylindrical cutter and conical cutter.
Based on three propositions, a global optimization theory of tool
positioning is described in detail. Firstly, a positioning strategy of
cylindrical cutter with least square is presented. Based on the method
of cylindrical cutter, a positioning strategy of conical cutter is
presented subsequently. At last, two examples are given to verify the
effectiveness of the developed flank milling technique. The results show
that the two methods are accurate and effective.
