Abstract
In this paper, turning input parameters were defined for 12 different polymer materials that can be used in technical practices. Our goal was to determine turning input parameters where chip formation is favourable or continuous chips do not cause any problems. Our tests included the examination of detached chips and the values of the average surface roughness of the machined surfaces.
Highlights
Polymers that exhibit good levels of machinability favour the development of chip formation
In this research, turning tests were performed to determine input parameters that can be used in practice to avoid such problems, e.g. melted surfaces, caused by continuously flowing chips
Even though the quality of the machined surfaces can be improved by tools with bigger radius, chips can still cause problems
Summary
The literature is mainly concerned with the study of types of chips generated during the machining of metallic materials such as C45 [1, 2], Al/SiCp [3] and AISI D2 tool steel [4]. Kharlevich and Venuvinod analysed the formation of 3D chips in general as a result of metal cutting [5,6], while others have researched methods of chip breaking for machining tools [7, 8]. Chip detachment and formation are very important aspects in machining, in the case of polymers, this area has not yet been investigated. 12 different polymer materials were tested, namely PA6 G-H, PA66 GF30, PET TF, PET, POM-C, POM-GF25, POM-H, PP, PTFE, PVC, textile bakelite and UHMWPE.
