Experimental Study on Exit Edge Defects in Two Dimension Cutting of SiCp/Al Composites

Abstract:

In this paper, the influence of the tool rake angle, cutting depth and cutting speed on exit edge defect sizes are discussed by the two dimension cutting experiment of SiCp/Al composites. The sizes are measured by using the Keyence VHX-1000C type super preview 3D microscopy. The results indicate that exit edge defect sizes are influenced greatly by tool rake angle and cutting depth, and are influenced slightly by the cutting speed. The edge defect sizes have an overall downward trend when the tool rake angle is smaller than 5°, and have an apparent upward trend when the tool rake angle (γ₀) is 10°.The length (L), height (H) of exit edge defects and the negative shear angle increase with increasing of the cutting depth.
