“…Due to the complexity of the drilling process, mechanistic modeling approaches have been used to model drilling forces and torques. Lazar and Xirouchakis [10] made an extensive review of existing mechanistic drilling models in the literature and also introduced a new mechanistic model to predict drilling forces. Karpat et al [11] proposed a mechanistic drilling model for double point angle PCD drills where cutting force coefficients were represented as a function of fiber direction.…”

Carbon fiber reinforced polymers (CFRPs) are known to be difficult to cut due to the abrasive nature of carbon fibers and the low thermal conductivity of the polymer matrix. Polycrystalline diamond (PCD) drills are commonly employed in CFRP drilling to satisfy hole quality conditions with an acceptable tool life. Drill geometry is known to be influential on the hole quality and productivity of the process. Considering the variety of CFRP laminates and available PCD drills on the market, selecting the suitable drill design and process parameters for the CFRP material being machined is usually performed through trial and error. In this study, machining performances of four different PCD drills are investigated. A mechanistic model of drilling is used to reveal trade-offs in drill designs and it is shown that it can be used to select suitable feed rate for a given CFRP drilling process.

“…is manufacturing method has an important place as it is used about 33% among traditional manufacturing methods [2]. In the drilling process, researchers conducted many works after having completed complicated operations and manufacturing processes in order to obtain the required highest sensibility and best quality [3]. A lot of parameters such as drill point angle, material used for drilling, and properties of drilling equipment affect the drilling process.…”

e chip slenderness ratio is a vital parameter in theoretical and applicable machining operations. In predrilled drilling operations of AISI 1050 steel alloy, HSS drills were employed, and the effect of the selected parameters on the chip slenderness ratio and also the effect of the chip slenderness ratio on the thrust force, surface roughness, drilled hole delamination, tool wear, and chip morphology were investigated. e major parameters, influential on the chip slenderness ratio, were feed rate and point angle, while spindle speed was too small to be negligible. With increasing the chip slenderness ratio, the thrust force and the tool wear decreased, which resulted in appropriate chip morphology, but there were increases in surface roughness. However, the chip slenderness ratio had no effect on the drilled hole delamination.
