“…Common assumption in simplified models considers the drill acting like a punch that pierces the laminate, see for instance [17,18]. This was the approach used by Durao et al [19] and Singn et al [20] when studying GFRP drilling; they showed the influence of the drill point angle in the induced damage.…”

CFRPs Drilling Delamination ModelingDelamination is one of the undesired effects of machining using non appropriate cutting parameters or worn drill. Finite element modeling of drilling of Carbon Fiber Reinforced Polymer (CFRP) composites is an interesting tool for damage prediction. Recently, complete modeling of the process including the rotatory movement of the drill, penetration in the composite plate and element erosion has been developed in the scientific literature. Computational cost of these complex models is a great disadvantage when comparing them with simplified models that consider the drill acting like a punch that pierces the laminate. In this paper both complete and simplified models were developed and compared in terms of delamination prediction. The simplified model, presenting reduced computational cost, slightly overestimates the delamination factor when compared with the complex model. The influence on delamination of thrust force, clamping area at the bottom surface of the laminate and the stacking sequence is studied using the simplified model.

“…Isik et al [9] reported, after a series of drilling experiments on glass fibre reinforced composites plate, that the delamination factor is higher at high feed rate and it is also increasing with the number of lutes and at high point angle. Singh et al [10] performed finite element analysis on drilling of composites reinforced with glass fibre and concluded that thrust is predominantly affected by the point angle and feed. Similarly, the thrust force and damage increases with increasing feed rate while performing drilling experiments on glass fibre reinforced composites [11,12].…”

Abstract. In this work, a new composite plate with natural jute fibre as the reinforcement fibres and isophthalic polyester as the resin was manufactured and subjected to a series of end milling operation by changing three input factors namely speed, feed rate and depth of cut. During each operation, the output responses namely thrust force and torque were measured. The responses were analyzed using Taguchi method to examine the relation between the input factors and output responses, and also to know the most influencing factors on the responses. The data was also analyzed using fuzzy rule model for prediction of responses for a range of input factors. The results showed that all three factors chosen have significant effect on the responses. The fuzzy model data in comparison with the experimental values shows only a marginal error and hence the prediction was highly satisfactory.

“…Therefore, metal removal processes like milling, drilling etc. are needed to meet the requirements of quality and dimension in assembly [6]. For example, structural weight of above 50% of Boeing 787 airplane is of composite materials and about 55000 drilling processes are performed in manufacturing of structural components in airplane [7,8].…”

Abstract. Surface damages and delamination occurred in drilling of the carbon fiber reinforced polymer composite materials, which change depending on their physical and mechanical properties and cutting conditions, and so affect the hole quality. Therefore, it is requires to be selective with regards to drill geometry and drilling parameters during drilling of CFRP. This study investigated the effects of cutting parameters and drill geometry on the hole quality in terms of hole diameter and surface roughness during the drilling of CFRP composite laminate. Drilling experiments were performed with three different levels of drilling parameters that are point angle, cutting speed and feed rate. At the end of the drilling tests, it has determined that if the feed rate increases, the surface roughness value increases while the hole diameter decreases. The feed rate was determined as the most important parameter with a PCR of 78.02% according to analysis of variance. The better hole quality was obtained with 130° drill among the three drill geometry.
