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.

“…They are also often more expensive than traditional turning machines due to the advanced technologies and materials used in their construction. However, their ability to produce high-precision parts can lead to significant cost savings and improved product quality in many industries [ [5] , [6] , [7] , [8] , [9] , [10] ] Ultra-precision CBN (Cubic Boron Nitride) turning is a machining process that utilizes CBN cutting tools to produce highly accurate parts with tight tolerances and excellent surface quality [ [11] , [12] , [13] ].…”
