“…The mechanism of machining has been recognized as a process different from that of homogeneous and isotropic metal removal of conventional materials. Moreover, several undesirable forms of damage (such as matrix cracking, delamination and fiber breakage) induced by drilling drastically reduce strength against fatigue, thus degrading the long-term performance of composite laminates [3,4].…”

“…However, drilling of NFRC is a rather intricate task due to the mechanical anisotropic and inhomogeneous structure, high abrasiveness, and hard reinforced fibers. Several note-worthy problems are related to the machining processes, particularly in drilling, including delamination, fiber peel up, thermal degradation, uncut fiber, fiber pullout, spalling and hole shrinkage (Kavad et al 2014). Among these, drilling-induced delamination is considered as the most critical damage because of its high level of impact on the quality of the drilled holes as well as their accuracy (Ismail et al 2016a).…”

This paper aims to investigate the effects of machining parameters such as spindle speed, feed rate and drill diameter on machinability of flax/poly(lactic acid) bio-composites, to analyze the relations among cutting forces, drillinginduced damages and crack propagation of the drilled samples. In particular, a set of drilling experiments were conducted using different drilling conditions and a new low-cost measurement set-up was developed to measure the cutting force during the drilling operation. In addition, the analysis of variance (ANOVA) was applied to identify the significance of each individual cutting parameter. The experimental results indicate the relation between the thrust force and the machinability parameters of flax fiber reinforced bio-composite.The increase in spindle speed reduces thrust force and delamination size of the drilled holes, whereas an increase in feed and drill diameter leads to a considerable increase in both thrust force and delamination factor. The effect of spindle speed on peripheral damage was not significant for the drills tested, though the feed rate was found to play the key role on the delamination damage area. The best hole quality was achieved with the samples drilled at spindle speed and feed rate of 3000 rpm and 0.11 mm/rev, respectively.

“…Kavad et al [19] reported a review work about drilling of GFRP and the following conclusions can be drawn: Cutting speed feed rate and tool material are the most influential factors on the delaminating in conventional area. So machining at higher cutting speed, hard tool material and lower feed rate cause lower failure of the GFRP.…”

Original scientific paper This paper has presented and discussed machinability in the drilling of SMC (Sheet Mould Compound) A-Class composite materials using Taguchi's DoE method. The thrust forces, surface roughness and push-out -peel-up delamination behaviour in drilling process for glass fibre reinforced SMC composites have been evaluated. The experimental results and the contribution ratio of parameters on machinability outputs have been statistically analysed by ANOVA. Analysis of variance shows that drill bit angle is the prominent parameter followed by feed rate and cutting speed that contributes towards output responses. Confirmation experiments performed with the optimum parameter condition levels show a reduction in thrust force by 9,8 %, surface roughness by 33,3 %, push-out delamination by 2,5 % and peel-up delamination by 1,38 %. A detailed deformation analysis was investigated for SMC composites. For the empirical modelling of machinability, outputs of SMC composites can be modelled with the quadratic polynomial regression model in a higher range of accuracy.

Procjenjivale su se potisne sile, površinska hrapavost i raslojavanje listanjem -ljuštenjem SMC kompozita ojačanih staklenim vlaknima u postupku bušenja. Eksperimentalni rezultati i veličina doprinosa parametara na rezultate obrade analizirani su pomoću ANOVA-e. Analiza varijance je pokazala da su važni parametri za izlazne rezultate prije svega kut alata za bušenje te brzina posmaka i brzina rezanja. Potvrdni eksperimenti provedeni uz optimalne parameter pokazuju smanjenje potisne sile od 9,8 %, površinske hrapavosti od 33,3 %, raslojavanja od 2,5 % i raslojavanja listanjem od 1,38 %. Provedena je detaljna analiza deformacije SMC kompozita. Za empirijsko modeliranje obradljivosti, rezultati SMC kompozita mogu se modelirati kvadratnom polinomskom regresijom u viši stupanj točnosti.
