摘　　要：非金属材料3204环氧玻璃布板在加工过程中容易出现变形、表面鼓包和端面片状撕裂等问题,故对材料特性进行了分析,指出了加工中存在的问题,包括零件精度和表面质量、切削温度对刀具的影响、加工工艺流程等,提出了调整优化加工工艺办法。选用合理的刀具几何角度,手工刃磨刀具,改善切削受力方向,以有效改善零件表面的撕裂状况,满足零件表面质量、尺寸精度和形位公差的要求,为加工低强度非金属材料提供了新思路。Non-metallic material 3204 epoxy glass cloth board is prone to transformation, bulge on the surface and sheet-like torn on the end face, etc. The study analyzes the characteristics of the materials;points out the problems, such as the influence of parts accuracy, surface quality and cutting temperature on the tool, and the processing, etc;and proposes the methods of the adjustment and optimization of processing. It is suggested to rationally select geometric angle of the tool and manual sharpen knives, improve cutting force direction, to effectively improve the tearing situation of spare parts’ surface, satisfy the requirements of component surface quality, dimensional accuracy, and form and location tolerance, and provide new thinking path for the processing of low strength non-metallic materials.
