Effect of Fiber Directions on the Surface Quality of Milling C/SiC Composites

  Its difficult to guarantee the surface quality when processing the carbon/silicon carbide (C/SiC) composites,and also easy to produce burr defect.So firstly the law of the burrs generated on different direction of fiber was analyzed theoretically.And then we milled the C/SiC composites by electroplating diamond cutting tool with different cutting parameters and fiber directions.The cutting force and the burr area size of the milling surface were also tested.After analyzing the results,the milling burr evaluation method was proposed.Then the burr area size of different fiber directions was analyzed,and the effect on the surface quality of fiber direction during milling process was studied.The result shows that the angle between surface laid carbon fiber direction and cutting direction has a significant influence on the processing quality.Milling surface quality was declined in order as 0°,45°,90° and 135°.So in order to improve the quality of the milling surface,the angle between surface laid fabric fiber direction and cutting direction should be less than 45°.
