DISK TOOL PROFILING FOR HELICAL SURFACES GENERATION USING BOOLEAN OPERATION METHOD

Abstract

In this work, there are suggested solutions for profiling the disc tool in machining a helical cylindrical surface with constant pitch. A graphical method has been developed in AutoCAD environment together with an analytical one. There are presented solutions for the disc tool axial section in both analytical and graphical form. Specially, this work presents a computational problem of determining the true shape on any section of a helical surface, especially on the section normal to the lead helix, while other documents only refer to  the section along axis and cross section. The authors used a combinative method of analytics, graphics and programming to solve that problem, applying to designing cutting tool in machining a helical cylindrical surface.
