“…In some drill geometries, the effect of spindle speed on torque were negligible [27][28][29][30][31][32][33]. At higher spindle speeds, the decrease in thrust force and torque is due to a softening of the matrix caused by a temperature increase and low coefficient of thermal conductivity of the fibers [29].…”

In the past few decades, polymer based fiber reinforced composites have been the prime materials chosen over the conventional materials in many industries, whereby drilling has been the secondary manufacturing process adopted for structural integration. Many specific characteristics of composites such as marked anisotropy, structural non-homogeneity, abrasiveness and lack of plastic deformation determine the behavior of composites during machining; this has makes it different than machining conventional materials in many respects. The principal objective of this work is to present a detailed literature review on drilling polymer composites with a focus on delamination. Aspects such as delamination mechanisms, fabrication methods, the type of drilling process adopted by various researchers, cutting parameters employed during drilling, mathematical delamination modelling, effect of thrust force, spindle speed, thermal loads, tool wear, surface roughness, tool geometry and tool materials on delamination and hole quality are summarized. In addition, the role of digital image processing in delamination assessment was also studied. Considerable efforts have been made by various researchers to comprehend delamination mechanisms, and there is still a demand for characterizing delamination with the implementation of nano-filler materials, the use of blended epoxy resins, reduced wear on drill tools, real-time drilling monitoring, the effect of stack supports and fiber stacking order, higher quality hole production and avoiding de-burring.

In this study, drilling of unreinforced polyamide and carbon black reinforced electrically conductive polyamide was performed with drill tools having different drill point angle at different cutting speeds and feeds. The surface roughness of drilled holes was measured and the chip forms were investigated. The experimental studies were designed by utilizing Taguchi L9 orthogonal series in order to obtain optimum drilling parameters and analysis of variance (ANOVA) statistical method was used to specify the effects of the process parameters on the surface roughness.

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.
