中文摘要：

选择3种核磁兼容非金属材料即聚丙烯、尼龙、聚甲醛进行切削力试验和粗糙度测量,分析不同切削参数下的三维切削力和粗糙度R a的变化规律。在此基础上,结合加工所获切屑形状,运用有向图和矩阵（DAM）法对3种材料的切削加工性进行评价,结果表明：尼龙切削加工性最优,聚甲醛其次,聚丙烯最差,因此宜选择尼龙作为核磁兼容机器人本体制造材料。

英文摘要：

Three kinds of MR-compatible non-metal materials,namely polypropylene,nylon and polyformaldehyde,are chosen for the measurement of their cutting forces and surface roughnesses.The variations of three-dimensional cutting force and roughness in the case of different cutting parameters are discussed.According to the above mentioned experimental results and the shapes of chips obtained during machining,the machinabilities of three materials are evaluated by using digraph and matrix（DAM） method.The result demonstrates that the nylon has the best machinability among the three materials,the polyformaldehyde takes the second place,and the machinability of polypropylene is the worst.Thus the nylon is selected for the main structure of the MR-compatible robot.
