Influence of Cutting Parameters on the Surface Quality of High Volume Fraction SiCp/Al2024 Composite

This paper studies the milling process of SiCp/Al2024 composite with high volume fraction and large particle size. The mechanism is analyzed. influence cutting depth feed per tooth on surface quality It reveals subsurface damage workpiece. results show that in composite, because edge radius much larger than radius, main form removal crushing. defects workpiece mainly include pits, cracks, scratches indentations. Appropriately increasing cut can improve increase will result increased deterioration quality. When increases from 4 ?m to 8 ?m, thickness layer 47.7 60.5 ?m. ratio between minimum blunt circle should be less 8%.
