“…In addition, a slight increase in surface roughness was observed when the depth of cut increases from 30 to 70 μm, which implies that larger depth of cut is not preferred for higher surface quality in machining CFRP composite. These simulated results are in good agreement with the experimental data [7,8]. The relations of surface roughness versus the fiber orientation angle and depth of cut are plotted in Fig.…”

“…An end-milling test on carbon nanotube reinforced composites has been conducted in [6], in which the surface roughness under various cutting parameters has been investigated by using the analysis of variance. The multiple regression analysis model of the surface roughness was offered to reveal the significant effects of feed rate, spindle speed, and depth of cut on surface quality in milling [7] and turning [8] glass FRP composites. A mathematical model of surface roughness was further studied based on the response surface methodology [9,10].…”

A three-dimensional (3D) micromechanical finite element (FE) model of machining of fiber-reinforced polymer (FRP) composites was developed in the paper. The FE modeling considers the three phases of a composite, in which the interphase between the fiber and matrix can realize interfacial debonding to represent the failure of composites and allow heat transfer. The machined surface observations and surface roughness measurements of carbon fiber-reinforced polymer (CFRP) composites at different fiber orientations were done firstly, and then, the model predictions of the machining responses, such as cutting force, temperature, and surface roughness, at different fiber orientations were compared with various experimental data for model validation. It is indicated that the three-phase micromechanical model is capable of precisely predicting machining responses and describing the failure modes of fiber shearing or bending related with fiber orientations in the chip formation process. To investigate the complex coupling influences of multiple machining parameters on the key responses of CFRP composites, the singlefactor analyses of each machining parameter were first carried out, and then, the multi-factorial analysis of multiple machining parameters was performed based on the orthogonal design of experiment and the analysis of variance (ANOVA) to quantitatively compare the influences of these key machining parameters on the cutting force and surface roughness. It was found that the fiber orientation angle, depth of cut, and cutting speed prove to be the important factors affecting the cutting force and surface roughness and that the coupling effects of these machining parameters all are relatively negligible in the machining of CFRP composites.

“…In a variance analysis, Davim and Reis (2005) studied the influence of various process parameters on different quality variables in the milling of CFRP with twill weave. Azmi et al (2013) recognized feed rate, depth of cut, number of teeth and cutting speed as main influencing parameters on delamination when milling GFRP with plain weave using unworn tools. Both studies do not consider any influence by the position of the milled edge relative to the yarn undulation.…”

“…It was found that the temperature within the CFRP just beneath the cutting point becomes lower as the cutting speed becomes higher. Azmi et al [23] researched the effects of cutting parameters on different machinability characteristics of GFRP milling and found that feed rate has the most dominant role in influencing the surface roughness. Phadnis et al [24] investigated the influence of drilling parameters on thrust force and torque both experimentally and numerically.…”

The cutting temperature and cutting force are some of the main factors that influence the surface quality of carbon fiber-reinforced polymer (CFRP). However, few investigations have been done on cutting temperature because it is difficult to capture the dynamic response of the temperature measurement system. Degradation of resin will occur within the machined surface or surface layer as the temperature exceeds the glass-transition temperature of the resin matrix. In this research, the relationship between cutting parameters and cutting temperature, cutting force were developed by response surface methodology (RSM). The experiments were designed using the tool-workpiece thermocouple technique. Taking into consideration the effect of the glass-transition temperature, the influence of cutting force and cutting temperature on surface quality of CFRP was analyzed. Analysis results showed that Spindle speed is the key parameter which influenced the cutting temperature while feed rate is the key parameter which influenced the cutting force in milling of CFRP. When the cutting temperature exceeds the glass-transition temperature (T g ), the matrix cannot provide enough support to the fibers, and the machining quality of composite material is poor.
