Abstract

Abstract: Machining performance can be improved by cooling with cryogenic assistance. This paper focuses on the influence of cryogenic cooling conditions using dry ice, solid carbon dioxide when drilling of PE-HD1000 plastic parts. The goal was to determine how the surface roughness of the drilled hole changes as a function of the cutting speed and the feed rate at room temperature and when cryogenic cooling is applied. The function relations were determined using Factorial Experiment Design. Improvement of the machinability of low temperature drilling results the improvement of roughness of the drilled hole.
