“…For these reasons, research developments have been carried out with the purpose of optimising the cutting conditions to reach a specific surface roughness [3,4]. The required quality of the machined surface depends on the mechanisms of material removal and the kinetics of machining processes affecting the performance of the cutting tools [5]. The works of a number of authors [6][7][8][9][10][11][12], when reporting on milling of FRP, show that the type and orientation of the fibre, cutting parameters, and tool geometry have an essential influence on the machinability.…”

The machining of fibre reinforced composites is an important activity for optimal application of these advanced materials into engineering fields. During machining any excessive cutting forces have to be avoided in order to prevent any waste product in the last stages of production cycle. Therefore, the ability to predict the cutting forces is essential to select process parameters necessary for an optimal machining. In this paper the effect of cutting conditions during milling machining on cutting force and surface roughness has been investigated. In particular the cutting force components have been analysed in function of the principal process parameters and of the contact angle. This work proposes experimental models for the determination of cutting force components for CFRP milling.

“…In a typical case of CFRP cutting, the orientation direction of the carbon fibers is an important factor in determining the wear process during the cutting process (Sakuma and Seto, 1983;Kaneeda, 1991;Wang, et al, 1995;Sreejith, et al, 2000). In addition, the cutting configuration (i.e., up or down cut) is also an important parameter.…”

“…The use of unidirectional CFRP laminates simplifies the analysis; it is easy to understand the mechanical interaction between a unidirectional CFRP laminate and a cutting tool. The mechanical response and cutting mechanism are highly dependent on the relative angle between the orientation of the carbon fibers and the traveling direction of the tool edge (Sakuma and Seto, 1983;Kaneeda, 1991;Wang, et al, 1995;Sreejith, et al, 2000) However, this study was focused on the effects of the type of material and the clearance angle of a two-layer tool on the reduction in cutting forces. In most of the tests conducted in this study, a unidirectional CFRP laminate with a thickness of 3 mm was used.…”

This paper describes a novel design concept for a tool for cutting carbon-fiber-reinforced plastic (CFRP) composites. The cutting tool, which is termed a two-layer tool, was fabricated from two materials with a spatial distribution of hardness around the tool edge. In the two-layer tool, the rake face is made of a material with a relatively high wear resistance, i.e., polycrystalline diamond (PCD), whereas the flank face is made of a material with a relatively low wear resistance, i.e., tungsten carbide (WC-Co). The results of milling tests conducted with a unidirectional CFRP laminate and the two-layer tool showed that the existence of a hardness distribution works to reduce cutting forces, because the wear process of the two-layer tool develops with a constant roundness at the tool edge over relatively long cutting distances. A simplified model was developed to describe how friction force is reduced. Increasing the difference between the wear resistances of the PCD layer and the WC-Co substrate and increasing the clearance angle of the tool edge were found to be effective in reducing the cutting forces. The finding of this study will be helpful in the development of novel design concepts for extending the life of tools for cutting CFRP composites.

“…[2] Milling composite material is significantly affected by the tendency of these materials to delaminate under the action of cutting force, feed force and depth force respectively. [3,4] Surface roughness is a characteristic that could influence the dimensional precision, the performance of the mechanical pieces and production cost. For these reasons there has been a lot of Research and Development with the objective of optimizing cutting conditions to obtain a determined surface roughness.…”

This Paper presents a study of surface roughness, precision and delamination factor in use of Ti-Namite carbide K10 end mill, Solid carbide K10 end mill and Tipped Carbide K10 end mill. A plan of experiment based on Taguchi was established with prefixed cutting parameters and the machining was performed. An Surfcoder to examine the surface roughness and Infrared Thermography to examine the delamination of chopped Glass fiber-reinforced plastic (GFRP) laminates was used. Earlier works reports that cutting velocity and feed rate makes significant contribution to overall performance. But, the experimental results of this paper indicates that the depth of cut are recognised to make the most significant contribution to the overall performance as compared to cutting velocity and feed rate. The objective was to establish a correlation between cutting velocity, feed rate and depth of cut with surface roughness and delamination in a GFRP laminate. The correlation was obtained by multiple-variable linear regression using Minitab14 software.
