“…The specific mechanism could be explained by the well-known phenomenon namely as "chip size effect" [61,62], which stated that there was a substantial reduction of the specific cutting energy with an increase of the uncut chip size. Such findings also agreed well with some experimental observations in either metal alloy cutting [61,62] or CFRP composite cutting [48,63] from the literature.…”

In manufacturing sectors, machining hybrid CFRP/Ti is usually an extremely challenging task due to the disparate natures of each stacked constituent involved and their respectively poor machinability. The current research focus of hybrid CFRP/Ti cutting was primarily made via the experimental studies, which exhibited high cost and time consuming. In this paper, a new contribution was provided to study the key frictional responses dominating the bi-material machining via the numerical approach. To this aim, a multi-physical model was developed by implementing different constitutive laws and damage criteria to construct the anisotropic machinability of the stacked composite. The interrelated effects of the multi-toolwork frictional behavior on hybrid CFRP/Ti cutting were precisely investigated with respect to the specific cutting energy consumption, machined surface morphology, and affected subsurface damage. A special focus was made to clarify the cutting sequence's influences on the hybrid cutting operation. The numerical results highlighted the reasonable CFRP → Ti cutting sequence for hybrid composite machining and the pivotal role of multi-tool-work interaction in affecting the frictional responses induced by cutting.

“…The influence of cutting parameters and fiber orientation on specific cutting energy in CFRP orthogonal cutting was studied. The specific energy will decrease with increasing of cutting speed and depth of cut [34]. However, the influence of γ0 and θ on the cutting energy distribution in CFRP orthogonal cutting process has not been reported in the literature.…”

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.

“…In the aerospace industry, thousands of high-quality holes have to be machined in order to assemble CFRP parts [6,7]. However, CFRP composites are difficult-to-cut materials due to their (i) anisotropic and (ii) inhomogeneous features, and because of (iii) the abrasive wear effects of their carbon fibres on the cutting tool [8][9][10][11][12]. Furthermore, in this case, carbon-chip treatment is also problematic [13] as the chips have to be removed from the machining zone due to (i) health issues and (ii) the wear effect of the carbon fibres on the different parts of the machine tool.…”

Due to its excellent specific mechanical properties, carbon fibre-reinforced polymer (CFRP) composite is a widely used structural material in the aerospace industry. However, this material is difficult to cut, mainly due to its inhomogeneity and anisotropic features and because of the strong wear effects of its carbon fibres. In the scope of aerospace industrial uses of this material, thousands of holes have to be machined for purposes of assembly. Nevertheless, conventional drilling technologyeven if special drilling tools are usedis only moderately able to manufacture good quality holes. Wobble milling is a novel advanced hole-making technology, which has been developed to minimize machining-induced geometrical defects like delamination or uncut fibres. The main objective of the present paper is to compare wobble milling, helical milling and conventional drilling technologies concerning unidirectional CFRPs. In addition, the kinematics of wobble milling technology is discussed in detail. In the scope of this paper, numerous machining experiments were conducted in unidirectional CFRPs: herein the impact of the type of cutting tool and of process parameters on the quality of machined holes are analysed and discussed (diameter of holes, circularity error and characteristics of uncut fibres). During these investigations, experimental data were evaluated with the help of digital image processing (DIP) and with the help of analysis of variance (ANOVA) techniques. Experimental results show that the amount of uncut fibres can significantly be minimized through the application of wobble milling technology.
