Comparative analysis of surface finishing for different cutting strategies of parts made from POM C

Abstract

This paper focuses on the comparing the resulting surface after finishing holes machined with different cutting technologies. The machined material is Polyoxymethylene polymer POM C. The cutting technologies that were used are: helicoidal milling, contour milling, head boring, and reaming. The main purpose of this paper is to establish the most appropriate finishing technology for a hole, depending on its functional role. The article compares each finishing process following the qualitative differences that occur. Qualitative analysis refers to the dimensional, shape and quality precision of the obtained surface. Surface quality was evaluated through its main parameters: surface roughness and surface texture. Following the evaluation of the worked surfaces, it was found that there are considerable differences between the finishing strategies that were used. The differences are considerable enough that one should consider using one technology instead of another depending on the use case. The results of this paper help in making faster decisions about what finishing technology to use when finishing holes in a POM C part depending on the functional purpose of the machined hole.
