“…The authors have underscored the insignificant effect of cutting speed on tool wear and surface roughness. Soriano et al 48,70 compared the tool wear of a proposed new tool and conventional surgical drill tool to compare their wear behavior at varying drill speeds between 250 and 1000 r/min by keeping the other parameters constant. The findings have shown high tool wear by increasing the cutting speed.…”

“…The authors have concluded the safe drilling parameters such as drill speed of 370 r/min, the feed rate of 70 mm/min, and applied drilling force of 140 N for minimum damage. Soriano et al 70 have compared the surgical and industrial drill bit to determine the temperature and frictional coefficient of the workpiece material. The findings have depicted the inverse relation of cutting speed with friction and temperature.…”

“…30,37,42,69 Udiljak et al 66 have concluded that feed rate has a direct relation with axial force and an inverse relation with the temperature. Soriano et al 48,70,78 highlighted that torque is directly proportional to feed rate. Some other researchers have mentioned that feed rate is a most influencing parameter affecting the thrust force and torque.…”

Bone drilling is a well-known internal fixation procedure to drill a hole, fixing the bone fragments to reduce the susceptibility of permanent paralysis. The success of bone drilling is evaluated based on the extent of osteonecrosis in terms of heat generation, tissue damage, quality of hole, and drilling forces. The appropriate control of cutting conditions, drill geometric parameters, and bone-specific parameters offer bone drilling a viable solution through conventional and non-conventional drilling techniques. The majority of the published research work considers only limited parameters and tries to optimize the drilling parameters and performance measures. However, bone drilling involves numerous conventional and non-conventional drilling parameters and technologies. In order to develop a better understanding of all the studied parameters and performance measures, there is a dire need to develop a framework. The key objective of this review study is to establish a hierarchy of the framework by collecting almost all the parameters studied until now and addressed the relationship between parameters and performance measures to diminish the controversies in the published literature. Therefore, this framework is novel in nature, organizing all the parameters, performance measures, logical comparisons, and limitations of studies. This holistic review can help medical surgeons and design engineers to understand the complicated relationship among parameters and performance measures associated with this state-of-art technologies. Also, modeling, simulations, and optimization techniques are included to explore the application of such techniques in recent advancements in orthopedic drilling.

“…The thrust force and torque have linear relationships with the chip area [10], and a larger chip area with a higher feed rate leads to a larger thrust force and torque [20]. In addition, the higher forces associated with a deeper cut at a higher feed rate can increase the chip evacuation torque and the friction between the drill margin and the bone [10,11,13,43], and the performance can deteriorate at deeper hole depths. It has been stated that increased torque can cause increased friction, resulting in increasing temperature and tool breakage [16,19,43].…”

Deep-hole bone drilling is critical in many surgical implantation procedures. Unlike most common bone-drilling processes, deep-hole bone drilling is performed using a high drilling depth to drill-bit diameter ratio, which can lead to undesirable mechanical and thermal damage during surgical procedures. The objective of this study was to investigate the thrust force and torque generated in deep-hole bone drilling. Drilling tests were performed on bovine cortical bones at a drilling hole depth of 36 mm using a 2.5 mm diameter twist drill bit with a spindle speed of 3000 rpm and feed rates of 0.05, 0.075, and 0.1 mm/rev. Bone chips were collected at different depths and examined using a fiber-optic microscope. Not only are drilling forces a good indicator to assess drilling performances but also chip formation and morphology are important aspects for understanding bone-drilling behaviors. The force signals revealed two distinct states, which were referred to as normal and abnormal states in this study. In the normal state, the force signals remained constant once the drill tip became fully engaged in bone cutting, whereas after a certain drilling depth, the forces considerably increased in the abnormal state. The results of this study indicate that the rapid increase in the force in the abnormal state is mainly attributed to chip clogging inside the flutes as the drilling depth increases. This study also demonstrated that the chip morphology varies with respect to drilling depth, where fragmented chips are produced at shallow drilling depths and powdery chips are produced at deeper drilling depths.
