This paper proposed solutions for profiling the disc tool in machining a helical cylindrical surface with constant pitch. A section method has been developed in AutoCAD environment together with a Boolean operation. Especially, this work presented a computational problem of determining the any section of a helical surface, 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 in designing cutting tool for machining helical cylindrical surfaces. |
