چکیده

Using the cutting of long fibre reinforced polymer and ceramic particle reinforced aluminium as the examples, this paper tends to understand some common features in the mechanics modelling of machining composites. It demonstrates that an accurate characterisation of matrix deformation, matrix–reinforcement interaction, and reinforcement deformation are key factors for the establishment of amodel to reflect the principalmaterial removalmechanisms. A precise understanding of these factors Composites

Modelling and Numerical Simulation of Cutting Stress in End Milling of Titanium Alloy using Carbide Coated Tool

Based on the cutting force theory, the cutting stress in end milling operation was predicted satisfactorily through simulation of using finite element method. The mechanistic force models were introduced in high accuracy force predictions for most applications. The material properties in the simulations were defined based on the cutting force theory, as a function of strain and strain rate wher...

Analysis of Milling Process Parameters and their Influence on Glass Fiber Reinforced Polymer Composites (RESEARCH NOTE)

Milling of fiber reinforced polymer composites is of great importance for integrated composites with other mating parts. Improper selection of cutting process parameters, excessive cutting forces and other machining conditions would result in rejection of components. Therefore, machining conditions are optimized to reduce the machining forces and damages. This work reports practical experiments...

Monitoring of tool wear using measured machining forces and neuro-fuzzy modelling approaches during machining of GFRP composites

The challenges of machining, particularly milling, glass fibre-reinforced polymer (GFRP) composites are their abrasiveness (which lead to excessive tool wear) and susceptible to workpiece damage when improper machining parameters are used. It is imperative that the condition of cutting tool being monitored during the machining process of GFRP composites so as to re-compensating the effect of to...

Deformation Characteristics of Composite Structures

The composites provide design flexibility because many of them can be moulded into complex shapes. The carbon fibre-reinforced epoxy composites exhibit excellent fatigue tolerance and high specific strength and stiffness which have led to numerous advanced applications ranging from the military and civil aircraft structures to the consumer products. However, the modelling of the beams undergoin...
