Progressive screw shaft manufacturing technology

Abstract

The progressive screw shaft is one of the very challenging part for machining. It might have a decisive influence on the precision of the parts processed by the machine tool. In this paper is presented a new, innovative technology of its manufacturing. The first goal is to develop a technological process for CNC milling machine. Technological process is fully described and with all parameters given and commented. Technology for progressive screw shaft manufacturing is developed in Autodesk Inventor HSM software. The second goal of the paper is a comparative analysis of the here described process for milling the different profile shapes. In the paper are given the milling examples of rectangular and circular profiles. Paper aims to emphasize the advantages and disadvantages of the proposed method. Some conclusions and directions to next research steps are given at the end of the paper.
