  Abstract

Polyetheretherketone (PEEK) composite belongs to a group of high performance thermoplastic polymers and is widely used in structural components. In order to improve mechanical and tribological properties, short fibers are added to unreinforced thermoplastics. Both unreinforced and reinforced PEEK composites find potential applications in manufacturing processes due to high specific properties and hence it is necessary to investigate the machining performance. This paper presents the application of response surface methodology (RSM)-based approach to study the machinability aspects of unreinforced PEEK, reinforced PEEK with 30% of carbon fibers (PEEK CF30) and 30% of glass fibers (PEEK GF30) composites with cemented carbide (K10) tool machining. The experiments are planned as per full factorial design of experiments and second order mathematical models are developed to establish the relationships between cutting conditions (cutting speed and feed rate) and machinability aspects (cutting power and specific cutting force). Analysis of variance is performed to check the adequacy of the models. The parametric analysis indicates that cutting power increases with increase in feed rate while the specific cutting force decreases for both unreinforced and reinforced composites. The results show that K10 tool provides better machinability for PEEK and PEEK CF30 materials as compared to PEEK GF30 work material.
