Abstract

Peripheral milling of very flexible components is a common manufacturing process in the aerospace industry. Many components used in the aerospace industry are usually thin-walled structures which is very flexible. Thin-walled structures are not rigid hence easily deflect due to cutting force during peripheral milling operation. The tool-workpiece deflection results in significant dimensional surface error which is highly undesirable. There is usually a significant deviation between the planned and machined part profiles that the machined parts may no longer be able to serve its original designated functionality. The geometry of cutting tool is one of the factors that must be considered in obtaining high quality milling. Primary relief angle is one of significant tool geometry that must be considered to obtain high cutting performance. This research studies on the effects of primary relief angle of endmill on the dimensional surface error of peripheral milling of thin-walled structure. Besides, the cutting force and surface roughness of the milled thin wall also investigated. The results obtained show that primary relief angle has significant effect to the dimensional surface error of thin-wall components where smaller primary relief angle has lower surface error.
