Analyzing Surface Quality Factors in CNC Milling of Polypropylene Plates

Abstract

– This study focuses on the analysis of surface quality factors in the CNC milling of polypropylene plates. Polypropylene, a versatile and widely used polymer, poses specific challenges during the milling process due to its unique properties. The research involves the utilization of a CNC machine to conduct milling operations on polypropylene plates with varying spindle speeds and feed rates. Surface roughness measurements are taken using a Mahr brand surface roughness measurement device, and the average values are recorded. The study aims to identify the key parameters that affect surface quality and to optimize the CNC milling process for polypropylene materials. Looking at the results, it has been observed that the milling of polypropylene plates results in different outcomes for average surface roughness and Rz values under various parameters.
