Influence of Cutting Parameters on Abrasive Machining of C/SiC Ceramic Matrix Composite

Abstract:

Ceramic Matrix Composites (CMC) are becoming increasingly important in aeronautical and space applications due to their excellent mechanical properties and wear resistance at high temperatures. Abrasive processes are commonly used for CMC machining due to its high hardness. In this work, an experimental analysis of the influence of grinding parameters has been carried out. Namely, the effect of the variation of cutting speed and feed speed have been studied when grinding a Cf/SiC composite with diamond wheels. Forces were registered during the tests and workpiece quality was analyzed by means of optical techniques. Results show that higher feed rates increase normal force values, while higher cutting speeds lead to lower normal machining forces. Moreover, a relationship between grain aggressiveness and specific grinding energy was observed. Decreasing machining forces also helped to preserve surface integrity of the machined parts.
