采用金属压铸法制备了A03190/304复合材料网络增强体试件。采用单因素试验方法对A03190/304复合材料试件进行了车削试验，并对加工表面粗糙度和完整性进行了分析。实验结果表明，加工表面粗糙度随切削速度的增加而减小，随进给量的增加而增大。加工表面粗糙度随切削深度的变化在车间操作的数值范围内变化不大。完整性研究表明，在加工过程中，有时会出现切屑的附着或嵌入及其划伤、基体与增强体之间的裂纹、增强体的剥离、增强体的凸起、基体的撕裂和基体的微裂纹等加工表面缺陷。试验结果表明，减小进给量、减小切削深度或提高切削速度，可以有效地控制已加工表面缺陷。(C)2016年卡拉布克大学。出版社：Elsevier B.

A03190/304 composite specimen with network reinforcement has been prepared by means of metal die casting. Turning experiments and analysis of roughness and integrity of machined surface on A03190/304 composite specimen have been done with single-factor experimental method. Experimental results show that machined surface roughness decreases with the increasing of cutting speed, increases with the increasing of feeding rate. Machined surface roughness changes slightly as the variation of cutting depth within the value range of workshop operation. The investigation of integrity shows machined surface defects happened sometimes such as the attachment or insert of chip and its scratching, crack between matrix and reinforcement, stripping of reinforcement, bump of reinforcement, tearing of matrix and micro cracks of matrix. Experiment results show that machined surface defects can be controlled by means of decreasing feeding rate and cutting depth or increasing cutting speed. (C) 2016 Karabuk University.
