Abstract:
Float glass, which is a hard and brittle material, is generally machined and drilled using rotary ultrasonic machining and conventional drilling to create products such as solar panels, metrological instruments, etc. But researchers are facing serious issues with regard to tool wear and opting for best shape of tool for the drilling purpose. In this study, blind holes are made on float glass specimen using rotary ultrasonic drilling and CNC conventional drilling process with the aid of multi-shaped tools. The opted tools are namely hollow abrasive tool, pin-pointed conical tool, flat cylindrical tools, and concave circular tool. The entire experimental work is accomplished by considering industrial conditions. Multi-shaped tool’s weight is computed at three stages i.e. (a) fresh tool, (b) after rotary ultrasonic drilling, and (c) after conventional drilling to analyze the overall tool wear. Apparently, micro-studies are used to investigate the phenomena of lateral and end face tool wear while creating blind holes at these three stages. It is revealed that the concave circular tool achieved a minimum percentage of weight loss i.e. 4.92% after conventional drilling and 1.96% after rotary ultrasonic drilling process, which could be preferred for drilling purpose followed by the hollow abrasive tool.

Abstract:
Aiming at the problem of poor machinability in conventional drilling of aramid/epoxy composites, the formation reason for fuzzing damage was analyzed. In order to obtain better machining quality, a combined machining technology based on sawing and grinding mechanism was proposed and the corresponding drilling tools were developed. Drilling experiments were conducted to explain the machining performance of the drilling tools. The results show that the sawing drilling tool with negative rake angle can effectively restrain fuzzing damage and the sawing-grinding drilling tool decreases the thrust force about 20%~55% with electroplated diamond abrasives. The combined machining technology of sawing and grinding achieves damage-free machining quality in drilling of aramid/epoxy composites.

Abstract:
The directional well drilling technology is extensively utilized and developed throughout the world. However, series of drilling problems occurred in the operation process of directional drilling. In order to reduce the friction of drilling tools, an oscillation tool with a fluidic amplifier has been field tested, and the pressure pulse of oscillation tool has been obtained. Field test results have shown that the oscillation tool has an extensive flexibility to directional well drilling, and the oscillation tool could stably actuate the drilling tool to have reciprocating vibration, which contributes to the friction and drag reduction of drilling tools. Furthermore, it can be concluded that the pressure pulse value generated by pumped fluid varies with input flow rate, and the pressure of oscillation tool increases while the flow rate is increasing. In addition, the motion frequency of the oscillation tool is exponentially increasing with the raise of pumped flow rate.

Abstract:
In orthopedic and trauma surgical operations, drilling of bone is one of the commonly used procedures performed in hospitals and is a clinical practice for fixing the fractured parts of human bones. Force, torque and temperature play a significant role during the bone drilling and decide the stability of the medical implants. Therefore, it is necessary to minimize force, torque and temperature while drilling to avoid the thermal necrosis and osteosynthesis. This study focused on studying the influence of various types of bone drilling parameters (rotational speed, feed rate, drill diameter and ultrasonic amplitude), tools (solid tool, hollow tool and conventional twist drill bit) and techniques (conventional surgical drilling, rotary ultrasonic bone drilling and rotary bone drilling) on force, torque, temperature and microcracks produced in the drilled surface of the bone. The experimental investigations were conducted on porcine bone samples to perform the comparative study. Results revealed that increasing the diameter of drill tool and feed rate results in the increase in force, torque and temperature, while low rotational speed (500 r/min) generated a low temperature, high cutting force and torque for all types of drilling processes and tools evaluated in this study. Experimental results also revealed that rotary ultrasonic bone drilling with hollow tool generated the lowest cutting force, torque, temperature (<47 °C) and microcracks in the drilled surface of the bone as compared to the other four types of drilling techniques evaluated in this study. Influence of external irrigation technique on temperature was also studied with respect to the rotary ultrasonic bone drilling with a hollow tool, which could eliminate the problem of thermal necrosis. In conclusion, this study revealed that the rotary ultrasonic bone drilling process with hollow tool produced lesser cutting force as compared to rotary bone drilling and conventional surgical drilling for hollow and solid tools. The study also revealed that rotary ultrasonic bone drilling process has the potential to minimize the cutting force, torque and temperature as compared to the conventional surgical drilling for orthopedic surgery.

Abstract:
This study describes a novel process to drill small holes in brittle materials such as glass, silicon and ceramic using a self-elastic polycrystalline diamond (PCD) drilling tool. In order to improve the surface roughness and reduce crack of the small holes, a new type of self-elastic PCD drilling tool equipped with vibration absorbing materials inside the housing was developed to fabricate small holes in glass in this study. The self-elastic PCD drilling tools could absorb the mechanical force by the vibration absorbing materials while the PCD tool penetrates into the small holes. Compared to conventional PCD drilling tools, the experimental results show that high-quality small holes drilled in glass can be achieved with cracking as small as 0.02mm on the outlet surface using the self-elastic PCD drilling tool.

Abstract:
Dry drilling of aluminum is environmentally friendly machining technique; in the meanwhile it is difficult to carry out due to aluminums gummy behavior and its tendency to adhere to cutting tools which diminishes hole quality. In spite of recent developments in cutting tool technology, HSS tools are still a cost effective choice due to relatively high toughness and feasibility to manufacture complex geometries of HSS drills besides its low price, make this tool a common choice for drilling soft materials such as aluminum. In this study effect of tool wear on thrust force and torque analyzed and hole quality assessed with respect to tool wear along tool life. Dry drilling on aluminum 2024, performed using HSS and HSCo drills at constant feed rate of 0.04 mm/rev and two cutting speeds of 28 and 94 m/min. Results revealed that the abrasive wear on flank face and BUE on chisel edge, margin and cutting lips were dominant mechanisms in all drills. It was found that with propagating the wear land on tool, thrust force and torque increased in both tools.

Abstract:
In this study, machinability of Zr-based bulk metallic glass (Zr52.5Ti5Cu17.9Ni14.6Al10) (BMG) material was investigated by conducting a set of milling and drilling experiments. In milling, two different tool paths, spiral and slot milling, were used. To investigate the behavior of BMG in drilling by two different tools at different feed rates, two sets of drilling experiments are conducted. Crown shaped exit burr formation are observed in drilling of BMG. Best results on thrust force, exit burr formation and hole surface roughness is obtained while using micrograin WC tool on BMG drilling. No chip light emission was observed during all tests. This study concludes that BMG can be achieved machining with good surface roughness, (Ra=0.113 µm), using conventional cutting tools.

Abstract:
The economics of drilling offshore wells is important as we drill more wells in deeper water. Drilling-related problems, including stuck pipe, lost circulation, and excessive mud cost, show the need for better drilling technology. If we can solve these problems, the economics of drilling the wells will improve, thus enabling the industry to drill wells that were previously uneconomical. Managed pressure drilling (MPD) is a new technology that enables a driller to more precisely control annular pressures in the wellbore to prevent these drillingrelated problems. This paper traces the history of MPD, showing how different techniques can reduce drilling problems. MPD improves the economics of drilling wells by reducing drilling problems. Further economic studies are necessary to determine exactly how much cost savings MPD can provide in certain situation. Furter research is also necessary on the various MPD techniques to increase their effectiveness.

Abstract:
The main objective of the work presented in this thesis is to investigate the two sides of the flute, the face and the heel of a twist drill. The flute face was designed to yield straight diametral lips which could be extended to eliminate the chisel edge, and consequently a single cutting edge will be obtained. Since drill rigidity and space for chip conveyance have to be a compromise a theoretical expression is deduced which enables optimum chip disposal capacity to be described in terms of drill parameters. This expression is used to describe the flute heel side. Another main objective is to study the effect on drill performance of changing the conventional drill flute. Drills were manufactured according to the new flute design. Tests were run in order to compare the performance of a conventional flute drill and non conventional design put forward. The results showed that 50% reduction in thrust force and approximately 18% reduction in torque were attained for the new design. The flank wear was measured at the outer corner and found to be less for the new design drill than for the conventional one in the majority of cases. Hole quality, roundness, size and roughness were also considered as a further aspect of drill performance. Improvement in hole quality is shown to arise under certain cutting conditions. Accordingly it might be possible to use a hole which is produced in one pass of the new drill which previously would have required a drilled and reamed hole. A subsidiary objective is to design the form milling cutter that should be employed for milling the foregoing special flute from drill blank allowing for the interference effect. A mathematical analysis in conjunction with computing technique and computers is used. To control the grinding parameter, a prototype drill grinder was designed and built upon the framework of an existing cincinnati cutter grinder. The design and build of the new grinder is based on a computer aided drill point geometry analysis. In addition to the conical grinding concept, the new grinder is also used to produce spherical point utilizing a computer aided drill point geometry analysis.

Abstract:
Drilling is a standard process for producing holes in metal materials. With an increased hole depth the demands increase on both machine and tool. Deep hole drilling is a complex process which ischaracterized by a high metal removal rate and hole accuracy. A hole deeper than ten times the diameter can be considered a deep hole which requires a specialized drilling technique. During adeep hole drilling process, the forces generated on the deep hole drill give a rise to a resultant radial force. The resultant radial force pushes the drill in a radial direction during a drilling operation. The radial force direction is of crucial importance in regard of tool guidance, stability and hole size accuracy. This force affects tool performance, reduces tool life and has an impact on the bore surface. Due to the complex nature of deep hole drilling, Sandvik Coromant wishes to get a better understanding of how their current deep hole drilling tools are balanced. The purpose of this study is to conduct a survey of a number of drills of Sandvik Coromant deep hole drill assortment. The main aim of this study is to calculate and measure the resultant radial force generated during a deep hole drilling operation. The forces are calculated with the aid of a calculation program and test-runs on a number of drills. This report presents the calculated magnitude and direction of the resultant radial force duringentrance, full intersection and at the exit of the workpiece. In addition to the measured values of theresultant radial force during entry and full intersection. Four different drill geometries are evaluated which of two are competitor drills. A deep hole drill geometry is re-modified in aspect to drill stability based on the outcome of the measured and calculated results. The results acquired from the performed calculation and measurements of the resultant showed that the resultant radial force acts in an angular direction that was outside the range between the support pads. This true for three of the four evaluated drill geometries. There were minor differences between the measured and calculated forces which enforce the reliability of the used calculation program. The modified drill geometry of a deep hole drill gave an indication of which geometry variables have impact on the resultant radial force magnitude and angular direction. The data presented in this report can be a base for future development of a deep hole drill toolgeometry in regard to the resultant radial force. Variables affecting the calculated results and theresultant radial force are presented and discussed. The study is concluded with suggestions of futurework based on the acquired data.

DTS is an oil and gas services company that delivers drilling tools to six major customer districts in the continental U.S. After the tools are used at a rig, they are transported to the closest repair and maintenance (MTC) facility in either Colorado (CO) or Oklahoma (OK) where they are disassembled and reconditioned for use on a future job. The tools are modular and require custom assembly and programming, depending on the requirements of the well. On occasion, DTS receives urgent orders for drilling tools to replace failed tools or to cater to unexpected demand. These urgent orders are expected to be delivered to customer sites in less than 24 hours from when an order is received. DTS wants to analyze the supply chain impact of consolidating MTC activities to a single facility for operational efficiencies. The rationalization of MTC activities to the CO facility affects DTS's ability to deliver tools within 24 hours due to the longer transportation times to customer districts. How can this longer transportation time be mitigated? Our research shows that using the OK facility as a postponement and distribution hub allows DTS to continue servicing expedited orders within 24 hours and results in a 28% logistics cost savings over a direct shipment method. The postponement strategy entails staging reconditioned inventory at both the OK and CO facility where they can be configured for use within 4 hours of receiving an order. By simulating the movement of inventory around the closed inventory loop, we determined that the total number of tools in the network and the MTC capacity are two important levers of control that affect the availability of reconditioned inventory to service demand. We found that we were able to fulfill a target item fill rate by calculating capital inventory required using an "order up to" inventory policy and setting facility capacity at one standard deviation above average demand.

Abstract:
Epiroc Drilling Tools is a manufacturing company that produces tools for rock mining and excavation. The company adopted the principles and framework of Lean Product Development in their R&D department with few practices of an agile framework called Scrum. These agile practices are used in the pre-study phase or the knowledge value stream of their lean product development. Hence, this research is limited to the knowledge value stream within the R&D department. The use of agile project management in manufacturing industry is unique and majority of the agile frameworks are specifically designed to suit the needs of software development companies. Several theories like Scrum, Lean, Kanban and DSDM were studied by the researchers to scrutinize the current framework of the department. The challenges and the similarities of the currently used framework with several other agile frameworks and the companies are discussed. Several qualitative research methods were adopted to know the viewpoints of the working employees in the department which are compared with other companies like Volvo Cars, ABB, LShift, EnergySoftware and from another division of Epiroc called Rocktec Automation who faced some similar challenges while practicing agile project management. After further research on the theories and comparison of the process, roles of the working employees and documentations within the knowledge value stream, DSDM had more similarities with the currently used framework than Scrum. This allowed to recommend ways that can fill the missing gaps using practices of DSDM without altering the existing working procedure in the knowledge value stream. This ensures that the improvement in the knowledge value stream remains continuous. On the contrary, a brief discussion is included on whether there is a need to be agile for manufacturing industries or is it just a changing trend in the field of project management.

Abstract:
The present work evaluates the performance of step drills, new and after regrinding. The tools were made of P20 cemented carbide coated with TiAlN. The routine of re-coating them after regrinding were varied (no recoating, recoating over the previous coating and recoating after removing the previous coating). The output parameters considered for determining the machining performance were: tool life, thrust force, torque, form errors (roundness and cylindricity) and surface roughness (Ra and Rz parameters). The results generated with the resharpened tools were compared to those obtained with a new tool (first time used). The results showed that in general the reground tools showed worse performance than the new tools, regardless the parameter considered. Only the tools that have undergone the process of cleanness of the previous coating and then reground and recoated (with the same type of coating) showed results similar to the new tools. The tools with no recoating and those that received the recoating over the previous showed, practically in all tests, higher thrust force and torque, larger form errors and worse surface roughness than the new tools.

Abstract:
This paper aims to investigate the effectiveness of super-hard ceramic coatings by evaluating tool wear when drilling carbon fiber reinforced plastics (CFRP) composite. The drilling experiments of CFRP are conducted with diamond-like coating (DLC) coated, AlMgB14 (BAM) coated, AlCrSiN coated, and uncoated tungsten carbide drills. Tool wear evolution is measured qualitatively as well as quantitatively using the scanning electron and confocal laser scanning microscopes. Both DLC and BAM coatings failed when drilling CFRP only within 10 holes while AlCrSiN coating did not fail. Failure mechanisms of each coating when drilling CFRP are discussed.
