Modeling and optimization of cylindrical grinding of Al/SiC composites using genetic algorithms

The Al/SiC composites have received more commercial attention than other kinds of Metal Matrix Composites (MMCs) due to their high performance. However, a continuing problem with MMCs is that they are difficult to machine, due to the hardness and abrasive nature of the SiC particles. Grinding is often the method of choice for machining Al/SiC composites to acquire high dimensional accuracy and surface finish in large scale production. Based on the full factorial design (3(4)), a total of 81 experiments, each having a combination of different levels of variables, are carried out to study the ef...
