Abstract
This paper presents a study on the experimental physical model of the orthogonal cutting on the composite polyetheretherketone (PEEK) and PEEK CF30 (reinforced with 30% of carbon fiber). The objective of this study is evaluating the influence of the reinforcement on the chip thickness ratio ( R), chip deformation ( ε), friction angle ( ρ), shear angle ( ϕ), normal stress ( σ) and shear stress ( τ) under prefixed cutting parameters (cutting velocity and feed rate). The experimental physical model was compared with the Merchant equation.
