Simulation Study on the Influence of Drilling Parameters on the Temperature of Skull Drilling
2021 IEEE International Conference on Electrical Engineering and Mechatronics Technology (ICEEMT), 2021Skull drilling is an important and difficult process in neurosurgical craniotomy, which will inevitably produce a lot of heat. Correct understanding of the heat production law of skull drilling has important guiding significance for craniotomy robot. In this study, cortical bone and cancellous bone were layered to establish models according to the 3D ...

Investigation into the effect of drilling parameters on delamination in drilling GFRP
Journal of Reinforced Plastics and Composites, 2010The purpose of this article is to investigate the influence of the cutting parameters, such as cutting speed and feed rate, and point angle on delamination and surface roughness produced when drilling a glass fiber-reinforced plastic composite. All tests were run without coolant at cutting speeds of 5, 10, 15, 20, and 25 m/min and feed rates of 0.1, 0 ...

Optimizing Drilling Parameters Enhances Horizontal Drilling Performance
SPE/IADC Middle East Drilling Technology Conference, 2001AbstractThe optimized selection of bits and mud type during any drilling operation improves significantly the drilling efficiency presented in high rates of penetration consequently less cost per meter.Hydraulics play also great part in optimization cycle by enhancing the ratio of the pressure loss across the bit nozzles to the circulating pressure ...

Publisher Summary Drilling rate is a function of weight on the bit, rotary speed, bit type, and size, hydraulics, bottom-hole cleaning properties of drilling fluid, and formation characteristics. Under controlled conditions of constant bit weight, rotary speed, bit type, and hydraulics, the drilling rate in shales decreases uniformly with depth. This

Cost Parameters in Geothermal Drilling
2021Energy is a basic need used in many fields from past to present. Therefore, the energy demand is increasing gradually. Today, although this energy demand is mainly met from fossil fuels, it can also be met by different methods such as nuclear power plants, geothermal power plants, solar and wind power generation facilities. However, an important factor

A Method for Drilling Parameters Evaluation, Applied for Drill Point Development
CIRP Annals, 1987During an investigation of machining parameters in drilling with Polycrystalline Diamond drills, methods to measure and evaluate the drill performance were developed. These methods enable the acquisition of all cutting forces, as well as cutting force distribution out of one standard drilling experiment.

The Effect of Dynamical Parameters on Precession in Rotary Drilling
Journal of Energy Resources Technology, 2001Precession, which is the rolling motion of the drillstring on the walls of the borehole, is investigated by considering the various possible motions of a rotating disk in a circular hole. Due to the simplicity of the model, closed-form results are derived on the stability of precession and on the evolution of impacting motions towards precession. It is

Effect of drilling parameters on mechanical strength in drilling glass fibre reinforced plastic
International Journal of Computer Applications in Technology, 2007The damage generated during the drilling of Glass Fibre Reinforced Plastics (GFRP) is detrimental for the mechanical behaviour of the composite structure. This work is focused on analysing the influence of drilling parameters (spindle speed and feed) on the strength of the GFR woven fabric laminates and further to study the residual stress distribution
