Microcutting is a precision technology that offers flexible fabrication of microfeatures or complex three-dimensional components with high machining accuracy and superior surface quality. This technology may offer great potential as well as advantageous process capabilities for the machining of hard-to-cut materials, such as tungsten carbide. The geometrical design and dimension of the tool cutting edge is a key factor that determines the size and form accuracy possible in the machined workpiece. Currently, the majority of commercial microtools are scaled-down versions of conventional macrotool designs. This approach does not impart optimal performance due to size effects and associated phenomena. Consequently, in-depth analysis and implementation of microcutting mechanics and fundamentals are required to enable successful industrial adaptation in microtool design and fabrication methods. This paper serves as a review of recent microtool designs, materials, and fabrication methods. Analysis of tool performance is discussed, and new approaches and techniques are examined. Of particular focus is tool wear suppression in the machining of hard materials and associated process parameters, including internal cooling and surface patterning techniques. The review concludes with suggestions for an integrated design and fabrication process chain which can aid industrial microtool manufacture.

“…An approach for machining tools represents the combination of mechanical x, y, z, B, and C axes, moving the tool with a galvo scanner for fast beam guiding. 14 This setup is suited for radial (orthogonal) and tangential processing where the position of the laser beam at the tangential incidence defines the final shape of the workpiece. This technology leads to a very high surface quality 15 but needs sophisticated path calculations.…”

Ultrafast lasers are frequently used to machine rotational symmetric workpieces either with tangential processing for tools or with a helical gravure approach for structuring cylinders for printing and embossing applications. The highest precision and repeatability for seamless multilayer processing on the surface of a rotational symmetric workpiece can be achieved by synchronizing a galvo scanner and a rotatory axis with the seed of the used laser system. With this technology, a repeatability of better than ±1μm is kept for hundreds of revolutions as it will be demonstrated for applications such as tube cutting and structuring of small embossing rollers.
