Study on Machining Accuracy of Scroll Shape Workpiece with Polar Coordinate Method

Abstract

This paper deals with machining accuracy of scroll shape. It is not easy to get high accurate machined surface using a end mill due to change of radius of curvature of the scroll. Therefore cutting tests are performed by high-speed machine tool with rotary table controlled by a polar coordinate method. And also the influence of type of milling, spindle speed and radial depth of cut on machining accuracy are considered.
