Tool-path Calculation for NC Machining the Helical Surface of Screw Shaft Based on the End Section
With the increasingly wide use of screw components in industry, technologies for efficiently fabricating the complex helical surfaces on these components play an important role in modern metal-working. In this paper, the helical surface of a screw shaft is mathematically modeled based on the profile of its end section, and the whirlwind milling process and its requirements for machining the screw using standard cutter blades are overviewed. Then a theoretical approach to calculating the tool path and the corresponding movements of the machine axes for producing such a helical surface are presented. Finally a case study is provided with an example screw whose end section is described using sampled points.
