Abstract

For the increasing demand of jewelry products, a self-designed multi-axis jewellery lathe is developed, which uses a PC control system based on VC and motion control card. In the process of development of the open CNC control system software, the unconventional ellipse curve and ellipsoidal helix interpolation besides the conventional line and circle interpolation should also be used during the CNC machining process. This paper specially studies the two interpolation algorithms based on the spacial structure of the lathe, and the achievements of the study has been put into practice.
