Abstract:

Real-time optimization of drilling parameters during drilling operations aims to optimize weight on bit, bit rotation speed for obtaining maximum drilling rate as well as minimizing the drilling cost. The process is considered to be formation specific. A statistical method such as multiple linear regression technique has been used for the drilling optimization. An extensive literature survey on drilling optimization was conducted for this research study. A model is developed for this purpose using actual field data collected through modern well monitoring and data recording systems, which pred

Abstract:

<p>In the woodworking industry, drilling (boring) is one of the most extensively used processes. Due to the traditional nature of the woodworking industry, not much data on machining has been recorded, only a fraction of this on drilling. This lack of information hinders the understanding and thus improvement in the process of drilling. The objective of this research is to provide a pilot study on chip clogging and the surface finish generated while drilling wood and also to examine the surface breakout at the point of drill entry and exit while drilling. This will help the industry by giving

Stabilitet och vibrationer inom invändiga svarvningsprocesser är ett område som kräver mer forskning. Tidigare studier visar att problem med stabilitet och utböjning är vanligt vid dessa processer och att de orsakar oönskade vibrationer i processen. Vibrationerna har en negativ effekt på bland annat ytjämnheten, som har visat sig vara en viktig parameter vid invändig svarvning. Syftet med den här studien var därför bland annat varit att undersöka utifrån vilka olika skärparametrar en konstruktions stabilitet kan säkerställas för att uppnå kravspecificerad ytjämnhet.

However, large scale use of NFRCs is still considered as challenging due to the difficulties in manufacturing, limited knowledge of its machinability and appropriate parameter settings, and being prone to machining-induced defects.

Abstract:

Dental implants are an effective alternative for the replacement of missing teeth. The success of the implant depends on how well a bone heals around the implant, a process known as osseointegration. However, excessive heat generated during the bone drilling will cause cell death and may prevent osseointegration of the implant, resulting in early failure. There are many factors which contribute to the heat generation during drilling. Experiments were carried out to investigate the affect of variable drilling factors on heat generation during drilling operation. Natural bone is not an ideal mat

Abstract:

Drilling operation expanded through deep water environments starting from mid-1980. As water depth increased, hydrate bearing formation in the shallow ocean floor is observed and that started to cause problems during drilling and production operations. Problems due to hydrate dissociation and forming during operations are also reported by the companies working in those environments many times. Although there are several factors affect the dissociation of shallow hydrate bearing sediments, heat flux from deeper sections of the well through shallower section during the operation is the major one

Abstract:

No<br>Optimisation of the drilling operations is becoming increasingly important as it can significantly reduce the oil well development cost. One of the major objectives in oil well drilling is to increase the penetration rate by selecting the optimum drilling bit based on offset wells data, and adjust the drilling factors to keep the bit in good condition during the operation. At the same time, it is important to predict the bit wear and the time to pull out the bit out of hole to prevent fishing jobs. Numerous models have been suggested in the literature for predicting the time to pull the

Abstract:

碩士<br>國立臺灣科技大學<br>材料科學與工程系<br>105<br>The demand for better tool performance in machining printed circuit boards (PCBs) is increasing due to the extensive usage of PCBs in digital electronic products. Therefore, higher density PCBs with smaller hole diameters, produced by small sized drill bits are required. However, the chip adhesion became more serious for drill bits with small diameters e.g. micro-drill bit, leading to a poor drilling performance as well as short drill life. To improve the drilling performance of micro-drill bits, surface modification, such as coating, have been widely appli
