“…It is noticed that 150% higher feed rate resulted to an increase inFy between 67% and 78.1% depending on the spindle speed. It can be also observed that when the spindle speed increases 100% ,Fy decreased between 26.7% and 30% depending on the feed rate.The simulation is consistent with the experimental observation [8].…”

Abstract-With wide application of carbon fiber reinforced plastics (CFRP) in aeronautic and astronautic products, the machining of FRP, particularly by means of milling is gaining more and more attention. In order to analysis the milling mechanism and process, both macro-mechanical and micromechanical 3-D finite element (FE) models were developed in this paper for machining simulation of unidirectional CFRP. Three-dimensional Hashin criterion is used for material damage prediction. The milling force simulated by two models was analyzed. The delamination is also simulated based on cohesive element in micro-mechanical model. The simulation result shows that the milling force and the delamination increase with increasing feeding rate, and decrease with an increase of the cutting speed, as is consistent with experimental observations.

“…Integrated process cells can be adapted to specific material requirements and to new process elements including laser based techniques for cutting applications [8][9][10]. Today, different cutting techniques like milling or water jet cutting are used, revealing respective advantages and disadvantages [11][12][13][14]. Laser cutting using high power laser sources offers many advantages, such as no tool wear, no water or moisture uptake and highest feed rates.…”

Abstract. In consequence of an increased interest in using endless carbon fibre reinforced thermoplastic composites (TPC), automated and highly productive processing technologies for cutting and trimming steps of consolidated materials are sought. In this paper, the influence on the thermal effect caused by laser cutting with respect to static strength properties of TPC based on a polyphenylene sulfide (PPS) matrix is studied. For the cutting experiments, consolidated TPC laminates at varying thicknesses up to s = 3.1 mm and a disc laser emitting at a wavelength of ! = 1030 nm at a maximum output power of P L = 2 kW are used. For the first time, the resulting magnitude of the heat affected zone (HAZ) at the cutting edge of the composite material is correlated with interlaminar shear strength tests. The results are compared to specimens prepared by milling and abrasive water jet cutting. Depending on the laminate thickness, the laser treated TPC samples show comparable properties to those of conventionally processed specimens. A reduced load bearing area, as a consequence of damaged fibre-matrix-adhesion due to laser impact, is identified as main factor for the reduction of interlaminar shear strengths for higher laminate thicknesses.

“…It was specified that the increase in the number of flutes and helix angles adversely affected the surface quality. 5 According to another study, the feed rate is also the most significant factor affecting the surface roughness. 31 Even the wear of the machining edge causes a high increase in the cutting resistance, which, in turn, leads to a plastic strain of the surface layers of the sample and delamination.…”

In this study, milling of a carbon-fiber-reinforced polymer composite material (CFRP) was investigated experimentally using various carbide end mills. The input parameters included the spindle speed, feed rate and cutting tool, whereas the output parameters were defined as the cutting force and surface roughness. The experimental design was based on the Taguchi L18 (6 1 ×3 2 ) orthogonal array. In the tests, six different carbide end mills with a 10 mm diameter were used: an uncoated two-flute 30°helix-angled one; carbide-coated two-, three-and four-flute 30°helix-angled ones; and TiAl-coated three-and four-flute 45°h elix-angled ones. The cutting parameters included three different feed rates (0.03, 0.06, 0.09) mm/tooth and three different spindle speeds (3800, 4800, 5800) min -1 . The Taguchi method was applied to select the most appropriate cutting parameters (cutting force, feed rate) for the tests. With the analysis of variance (ANOVA), the feed-rate factor was found to be the most effective one among these parameters (cutting forces and surface roughness). The results of the experiments showed that the uncoated carbide end mill had a better performance in terms of the cutting forces and surface roughness. Besides, it was also seen that the surface roughness increases with the increasing number of flutes and helix angle. Keywords: CFRP, cutting forces, surface roughness, Taguchi method, ANOVA V {tudiji je bil eksperimentalno prou~evano rezkanje polimernega kompozitnega materiala, oja~anega z ogljikovimi vlakni (CFRP) z uporabo rezkarjev z razli~nim karbidnimi nanosi. Vhodni parametri so vklju~evali hitrost vrtenja vretena, hitrost podajanja in rezalno orodje, medtem ko sta bila izhodna parametra sila rezanja in hrapavost povr{ine. Zasnova eksperimenta je temeljila na Taguchi L18 (6 1 ×3 2 ) ortogonalni matriki. Pri preskusih je bilo uporabljenih {est razli~nih cilindri~nih rezkarjev s premerom 10 mm, dvorezni s kotom spirale 30°brez nanosa, dvo, tri in {tirirezni s kotom spirale 30°prekriti s karbidi ter tri-in {tirirezni rezkar s kotom spirale 45°in nanosom TiAl. Uporabljeni parametri rezanja so vklju~evali tri razli~ne hitrosti podajanja (0.03, 0.06, 0.09) mm/zob in tri razli~ne hitrosti vrtenja vretena (3800, 4800, 5800) min -1 . Za izbiro najprimernej{ih uporabljenih parametrov (sila rezanja, hitrost podajanja), je bila uporabljena Taguchi metoda. Med uporabljenimi parametri (sila rezanja in hrapavost povr{ine) se je pokazalo, s pomo~jo analize variance (ANOVA), da je hitrost podajanja najbolj vpliven faktor. Rezultati preskusov so pokazali, da ima rezkar brez nanosa karbida, bolj{e zmogljivosti glede na sile rezanja in hrapavost povr{ine. Poleg tega se je pokazalo, da hrapavost povr{ine nara{~a z ve~anjem {tevila utorov in kota vija~nice.
