a study on tool wear and surface roughness in end milling of particulate aluminum metal matrix composited:application of response surface mehodology

Metal matrix composites MMCS have been widely used in industies especially aerospace industris due to their excellent engineering properties however it is difficult to machine them because of the hardness and abrasive nature of reinforcement elements like silico n carbide particles Sicp in the present study an attempt has been made to investigate the influence of spindle speed N feed rate f depth of cut d and various %wt.of silicon carbide s manufactured though stir cast route on tool flank wear and surface roughness during end milling of LM25 Al-SICp metal matrix composites .statistical models based on second order polynomial equations were developed for the different responses analysis of variance ANOVA was carried out to identify the significant factors affecting the tool flank wear and surface roughness the contour plots were generated to study the effect of process parameters as well as their interactions. the process parameters are optimized using desirbility based approach response surface methodology.
