Research Abstract

This study deals with the development of the device for machining holes with variously changing cross sections, i.e., cross section's changing holes, which cannot be fabricated by means of conventional machining methods, and the formulation of one of the important parts constituting the software system for creating holes with complicatedly changing cross sections by making good use of the developed device. The results obtained in the machining experiments using the device and software show that the holes with complicatedly changing cross sections whose shape are previously designed can be created. This proves the effectiveness of the device and software.
