“…The force increases for the across orientation. A similar behaviour was found for other composites CFRP and GFRP as it is shown in [49]. The orientation transversal to the plane also leads to increased values of the cutting force.…”

Cutting operations in bone are involved in surgical treatments in orthopaedics and traumatology.The importance of guaranteeing the absence of damage in the living workpiece is equivalent in this case to ensuring surface quality. The knowledge in this field is really far from the expertise in industrial cutting of mechanical components. Modeling of bone cutting is a challenge strongly dependent on the accurate modeling of mechanical behaviour of the bone. This paper focuses on modeling of orthogonal cutting of cortical bone. The intrinsic anisotropic nature of the cortical bone that makes it comparable to a compos-ite material is taken into account. The influence of anisotropy is analysed comparing this behaviour with an isotropic approach. It is shown that both chip morphology and temperature are affected by the anisot-ropy of the cortical bone that acts as a workpiece.

“…The concept of degrading the stiffness of the composite in certain directions has been used in study composites failure including machining of composites [11,15,17]. In this study, the stiffness degradation values were adopted from [47] and are shown in Table 2.…”

“…Material failure is governed by composite failure criteria. 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.…”

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.

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.
