Methods to Improve Surface Finish of Parts Produced by Fused Deposition Modeling
Fused deposition modeling (FDM) is one of the rapid prototyping technologies that can use plastic material, which can be effectively used for making patterns for investment casting. The surface finish of the investment casting depends upon the surface finish of the pattern. But the surface finish of the parts produced by using FDM is not very good as compared to wax patterns, which are conventi...
متن کاملSurface Finish and Residual Stresses Induced by Orthogonal Dry Machining of AA7075-T651
The surface finish was extensively studied in usual machining processes (turning, milling, and drilling). For these processes, the surface finish is strongly influenced by the cutting feed and the tool nose radius. However, a basic understanding of tool/surface finish interaction and residual stress generation has been lacking. This paper aims to investigate the surface finish and residual stre...
متن کاملRanking of fibre-reinforced composite plate surface finish quality by wavelet texture analysis
In the automotive and other industries, the visual appearance of external surfaces is a key factor in perceived product quality. Traditionally, the quality of automotive surface finish has been judged by expert human auditors. A set of 17 fibre-reinforced composite plates was previously manufactured to have a range of surface finish quality, and these plates were previously ranked by three expe...
متن کاملEffect of Process Variables in Abrasive Flow Machining
When an abrasive mixed with a polymer of special rheological properties and forced through a restricting medium, the abrasive and polymer will act as a self forming tool that precisely removes work piece material and improve the surface finish at those areas restricting to the medium flow. It is capable of machining areas which are difficult to reach by conventional machining and can be used to...
متن کاملExperimental study of Roller burnishing process on plain carrier of planetary type gear box
Burnishing is cold working process where hard roller are being pressed against irregular surface, so that surface finish and the micro hardness increases. In this study internal roller burnishing tool is used to burnish the drilled hole. Speed, feed, and number of passes have been varied using taguchi method to examine the surface finish and microhardness. Anova analysis is carried out. Surface...
