Abstract Chemical vapor deposited (CVD) diamond is a promising material to fabricate micro-cutting tools owing to its ultra-high hardness, Young's modulus, and isotropic characteristics. In this research work, a novel compound process of laser-induced graphitization coupled with precision grinding, was proposed to fabricate CVD diamond micro-milling tool.
An important aspect for the development of micromanufactured components and systems is to reduce the time and cost required to reach the prototype stage. At present, this development typically spans several years. Any fabrication approach which would reduce the cost and time-to-prototype would allow for the more rapid development of design concepts and the more rapid …
Because micromilling cutting tools have such small diameters, the spindle speed is often too slow to produce a high cutting feed, which, in turn, limits the maximum attainable feed rate. For example, to maintain a cutting feed of 100 meters per minute with a 10-mm cutter, the spindle should rotate at approximately 3,200 rpm.
