Abstract: A two-dimensional plane single grit cutting model is established by using finite element analysis software of ABAQUS.The machining process of a single abrasive particle for cutting SiCp/Al composites with volume fraction of 45 % was studied.The effect of different machining parameters on cutting force and machined surface topography after cutting was analyzed through the experiment and simulation method.The experimental and simulation results show that the cutting depth has much more effect on the cutting force than the cutting speed in certain conditions.When the cutting depth are the fixed value,the cutting speed has little effect on the cutting force;when the cutting speed are fixed value,the more depth of cut is,the more force of the cutting can be gained.The effect of single diamond grit on reinforcement in composite materials is embodied in the rotation and movement of SiC.Discrete holes of the SiC particles are the main formed surface defects in the process.

Key words: SiCp/Al, single grit, diamond, cutting force, surface topography
