Technology optimization of PPS/C composite milling using Taguchi method

This paper focuses on machining of thermoplastic composite PPS (polyphenol sulfide) with carbon fibers. This material is one of the most promising materials in industry today. PPS/C is a commonly used material in the aerospace and aircraft industry for internal panel design etc. Trimming using milling technology is a possible technology for finishing of the workpiece after prefabrication. In this paper three cutting tools are compared based on the criterion of the final quality of the machined surface edge using Taguchi method design of experiment (DOE). The criteria of comparison are surface roughness, pullout fibers and proportion of forces.
