Abstract

The necessity of understanding the influence of cutting variables in orthogonal cutting of Carbon Fiber Reinforced Polymer (CFRP) is vital because of their significant influences to the quality of manufactured parts. In this present research work the influences of different cutting depths to the cutting and thrust forces have been analyzed and a comparison between an equivalent homogeneous material (EHM) macro-model and experimental results have been made. The reasons of the beginning high cutting and thrust forces have been studied and explained. The post analysis of the experimental machined surfaces has been done to analyze the generated surface roughness and fiber-matrix interface crack generation. Five different cutting depths and four individual fiber orientations have been tested both numerically and experimentally. Significant influence of cutting depths to the cutting force has been found and the surface quality of newly generated machined part is discovered as a function of cutting depth and fiber orientation.
正交切削中不同切削深度对CFRP零件切削力及加工质量的影响:数值与实验比较
碳纤维增强聚合物(CFRP)正交切削中切削变量的影响对制件质量有重要影响,因此了解切削变量的影响至关重要。本文分析了不同切削深度对切削力和推力的影响,并将等效均质材料(EHM)宏观模型与实验结果进行了比较。研究并解释了初切力和推力大的原因。对实验加工表面进行了后置分析,分析了表面粗糙度和纤维-基体界面裂纹产生情况。对五种不同的切割深度和四种不同的纤维取向进行了数值和实验测试。发现切削深度对切削力有显著影响,并发现新加工零件的表面质量是切削深度和纤维取向的函数。
