  • Drilling operations are perhaps the most popular machining process being undertaken today, with their origins being traced back to cutting tool developments in North America in the 19th century. In 1864 toward the latter part of the American Civil War, Steven Morse (i.e. later to design the significant ‘Morse taper’ – for accurate location of the ‘sleeved drills’ into their mating machine tool spindles) founded the Morse Twist Drill and Machine Company in the ‘North’.

  • Machining (turning, milling, drilling) is the most widespread metal shaping process in mechanical manufacturing industry. Worldwide investment in metal-machining machine tools holds steady or continues to increase year by year, the only exception being in the worst of recessions. The wealth of nations can be judged by this investment. Figure 1.1 shows the annual expenditure on machine tools by each of the most successful countries – Germany, Japan and the USA. For each,

  • The dissemination of micro-electronics during the 1980s led to innovation. On the leading edge of these technologies was the machine tool subsector. However, the Japanese were the first to apply advanced controls and gained shares in global markets propelled by their lead. Since then Europe has caught up and ME competes at eye level with Japan. 10 A detailed assessment of the technological position in this area and other fields of relevance for ME, such as nanotechnology, optics, new materials and composites, is performed in Chapter 0.

  • Drilling is the process most commonly associated with producing machined holes. Although many other processes contribute to the production of holes, including boring, reaming, broaching, and internal grinding, drilling accounts for the majority of holes produced in the machine shop. This is because drilling is a simple, quick, and economical method of hole

  • Machining operations (e.g., drilling, milling) are shape transformation processes in which metal is removed from a stock of material to produce a part. The objective of these operations is to produce parts with specified quality as productively as possible. Many phenomena that are detrimental to this objective occur naturally in

  • Circumferences of circles are used in calculating speeds of rotating machine parts, including drills, reamers, milling cutters, grinding wheels, gears, and pulleys. These speeds are variously referred to as surface speed, circumferential speed, and peripheral speed; meaning for each, the distance that a point on the surface or circumference would travel in one minute.

  • Medical devices are instruments, apparatuses, implements, machines, contrivances, implants, or in vitro diagnostics and are intended for the cure, mitigation, treatment, diagnosis, or prevention of disease. They are intended to affect the structure or function of the body through means other than chemical action and independently of being metabolized. In the past few decades there has been greater recognition of how critical they are to delivering state-of-the-art medical care, as their use in the delivery of medical care has always been ubiquitous.

  • Not all materials can be etched in an easy and cheap way. Especially, noble metals or tantalum are stable against most of these corrosive structuring methods. Hence, precision machining may be used to generate microstructures from these metals as well as from standard metal alloys such as stainless steel or hastelloy. Depending on the material, precision machining can be performed by spark erosion (wire spark erosion and countersunk spark erosion), laser machining or mechanical precision machining.

  • Whereas spark erosion and lasermachining are suitable for any metal, the use of mechanical precision machining and the tools suitable for this type depend on the stability of the alloy. For brass and copper, natural diamondmicrotools are suitable and widely used, while for stainless steel and nickel- based alloys, hardmetal tools are needed. Figure 1.3 shows a natural diamond cutter, whereas Figure 1.4 shows a hard metal drill. Figure 1.5 shows photos of a rhodium honeycombmicrochannel catalyst system.
