Machinabilty of Advanced Ceramic for CADCAM Applications 2001-01-0766
In almost all-manufacturing processes, there is a trade-off between cost and quality. Parameters that indicate quality include surface texture, dimensional accuracy, mechanical properties and uniformity of physical appearance. Unfortunately, parts with good surface finish, precise geometry and high mechanical strength are usually the most expensive to produce. In order to achieve high quality components at reasonable cost, optimisation of machining is essential. This is usually accomplished by judicious selection of proper cutting tool, cutting method, and the various cutting parameters that control the process.
It is the intention of this paper to demonstrate research efforts aimed at characterizing and machining of CAPTAL‘90’, a hydroxyapatite (HA) material-suitable for human bone tissue replacement. It is expected that experimental knowledge gained and the results will form basis for modification of hydroxyapatite material for better machining performance. Guidelines for future machining of hydroxyapatite and other related advanced ceramic materials are proposed.
