✦ Synopsis

tion distance, s, between the cutter and workpiece axes and the setting angle, ␣, as shown in Figure 1. Each machine setup can lead to a different solution for the required cutter or workpiece profile.

Historically, cutter profiles for helical grooves have been designed by graphical trial-and-error methods (Dudley and Poritsky 1943). To overcome the inherent inaccuracy of this approach, analytical methods were developed to design the required cutter profile or to find the helical groove. These methods can be divided into two classes. The first class is based on graphic reasoning (Friedman, Boleslavski, and Meister 1972;Kaldor and Messinger 1988;Veliko, Nankov, and Kirov 1998), which considers the trajectories of selected points on the cutter profile. The results are visually presented as the envelope of the trajectories in the workpiece transverse section. However, this method cannot be directly applied to finding the cutter profile to generate a
