Abstract
An approach to optimisation of the polishing of ceramic blocks with multiple performance characteristics, based on reliability analysis, Taguchi and grey methods, has been studied. Speed, load, diamond size and concentration are optimised polishing parameters when the performance characteristics, which include Weibull modulus and removal rate, are taken into consideration. Optimisation with multiple performance characteristics is found to be the highest speed and greatest load, and diamond particles of 3 μm size and 45% concentration. Analysis of variance shows that the most significant polishing parameters are load (52.46%) and speed (33.09%), followed by diamond particle size (8.21%) and concentration (6.24%). Experimental results have shown that the multiple performance characteristics of polishing of ceramic blocks are greatly improved through this approach.
