Review of accuracy improvement techniques in high speed 5 axis machining

The modern metal machining industry has overcome their limitations of working in order to machine all the points of the work piece. 5 axis machine tools have demonstrated the capability to perform intricate machining operations. Various machining operations involving undercut areas, deep cavities, sharp corners are demonstrated successfully using 5 axis machine tools. However, to perform these operations, often special fixtures, special tooling, tools with longer out sticks, and expensive electrodes are needed. These auxiliary tools are needed to achieve high quality with shorter manufacturing time. This further also leads to substantial saving of the manufacturing cost. Recent developments in CAD/CAM also have made greater impact on the efficient utilization of the 5 axis machine tools. Special attention is given to cutting tools and tool holding systems that support the whole process. This paper focuses on the review of the techniques applied to utilize 5 axis machine tools to improve the quality of the product with lesser machining time.
