“…Simulation studies revealed a jet cooling microchannel internal configuration was the most efficient cooling method. For the WC tooling insert used in the study, modification strengthening of the internal tool structure indicated a 0.8 μm channel diameter located 1 mm away from the locus of the cutting edge, provided for improved mechanical strength [48]. However, the effectiveness of the internal coolant in temperature reduction was minimal overall.…”

“…Ghani [48] investigated the design of internally cooled cutting tools and their potential for machining grade 2 commerically pure (CP) Ti. Analysis of thermocouple, pyrometer, and infrared (IR) cameras indicated that embedded thermocouples were the superior option in terms of reproducibility and accuracy, as measurement of the material surface emissivity proved too difficult for IR sensors.…”

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.

“…In summary, four main steps need to be carried out before establishing the communication with the FANUC CNC controller: FOCAS enables the reading and writing of CNC data from the FANUC controller via Ethernet. The sequence diagram of an application program for the communication with the FANUC CNC controller is depicted in figure 15 [28].…”

This paper presents an innovative design of a smart cutting tool, using two surface acoustic wave (SAW) strain sensors mounted onto the top and side surface of the tool shank respectively, and its implementation and application perspectives. This surface acoustic wave -based smart cutting tool is capable of measuring the cutting force and the feed force in a real machining environment, after a calibration process under known cutting conditions. A hybrid dissimilar workpiece is then machined using the SAW -based smart cutting tool. The hybrid dissimilar material is made of two different materials, NiCu alloy (Monel) and steel, welded together to form a single bar; this can be used to simulate an abrupt change in material properties. The property transition zone is successfully detected by the tool; the sensor feedback can then be used to initiate a change in the machining parameters to compensate for the altered material properties.
