“…The effect of the friction coefficient was found minimal in the proposed mode. This is supported by the work of Nayak et al [10], where they determined the friction coefficient as a function of fibre orientation using pin on disk experiments, then ran simulations with and without friction and found that only thrust force magnitude was marginally affected by friction.…”

“…Among the meshfree parameters, the size of DoI was found more significant than weight function. A good rule of thumb for choosing DoI is to use the minimum value that maintains the invertibility of the A matrix, see Equation (10). An added advantage of smaller DoI is the reduction of the computational cost as fewer nodes are used in stress calculations at each integration point.…”

“…Different studies used various failure criteria, such as Tsai-Hill [8,10,14], maximum stress [10,11], Hashin [11,15,17]. Some studies [8][9][10] combined two failure mechanisms, primary failure for the onset of chip formation and a secondary failure for the progressive failure and completion of chip formation. The progressive failure was modelled through stiffness degradation concept [11] or continuum damage mechanics approach [15][16][17] .…”

As a service to our customers we are providing this early version of the manuscript. The manuscript will undergo copyediting, typesetting, and review of the resulting proof before it is published in its final form. Please note that during the production process errors may be discovered which could affect the content, and all legal disclaimers that apply to the journal pertain. Simulations show that the meshfree model is capable of predicting cutting forces as a function of the fibre orientation. Sensitivity analysis is conducted to investigate the effect of important meshfree parameters such as the domain of influence and weight function on forces. One of the strongest advantages of the proposed model is the simple and automatic set up process, as meshing for domain discretisation is not required.

Abstract:The machining of carbon fiber reinforced polymer (CFRP) composite presents a significant challenge to the industry, and a better understanding of machining mechanism is the essential fundament to enhance the machining quality. In this study, a new energy based analytical method was developed to predict the cutting forces in orthogonal machining of unidirectional CFRP with fiber orientations ranging from 0° to 75°. The subsurface damage in cutting was also considered. Thus, the total specific energy for cutting has been estimated along with the energy consumed for forming new surfaces, friction, fracture in chip formation and subsurface debonding. Experiments were conducted to verify the validity of the proposed model.

This work focuses on the analysis of the influence of mechanical properties of long fiber reinforced polymeric composite (LFRP) on machining operations. Experimental works covering main aspects of the machining process, such as tool selection, wear evolution, and cutting parameters were briefly reviewed. It can be concluded from this analysis that the composite properties strongly influence machining process. The selection of the tool, both cutting material and geometry, should be done depending on the type of composite family (carbon, glass, or aramid). This aspect also influences the evolution and mechanism of tool wear. On the other hand, numerical modeling is a useful tool to get a better knowledge of machining operations. Mechanisms of chip generation, cutting forces, and damage can be evaluated depending on the workpiece properties. Finite element approach involves modeling the mechanical behavior of the composite, material properties influence damage generation through the models formulation.
