“…high thermal and mechanical tool load emerged near the cutting edge and increase the temperature inside the tool and hence tool wear. Based on a study of Bleicher et al [28,29], conventional coolant was led through the cutting insert to dissipate heat directly near the cutting edge. The internal cooling strategy combined with an external coolant supply resulted in a reduction of tool wear when machining P750.…”

“…Compared to cryogenic cooling, the cooling temperature is marginally higher and the heat dissipates directly from the tool tip without any thermal shrinking of the tool as observed by Mayer et al [26]. This cooling strategy shows excellent results for the machining of aluminium and cast iron hybrid components [28,29]. For this reason, using the same cooling approach is expected to show promising results also for machining of austenitic stainless steels.…”

“…For differently prepared cutting inserts, changes in the microstructure of α'-martensite as well as the surface roughness were observed [27]. Bleicher et al [28,29] designed an innovative cooling approach in which cutting inserts are cooled externally or internally with conventional coolant supplied by the machinery. Compared to cryogenic cooling, the cooling temperature is marginally higher and the heat dissipates directly from the tool tip without any thermal shrinking of the tool as observed by Mayer et al [26].…”

Austenitic steels are used in different areas of application where high strength and corrosion resistance are necessary at low and intermediate temperature levels. Machining these materials therefore induces high mechanical and thermal loading and reduces tool life and the overall process performance. A well-known approach to raise tool life is to dissipate the heat from the cutting edge. This paper presents some findings of a combined externally and internally cooled cutting insert compared to a solely externally cooled cutting insert.

“…Precision boring (or in this specific case precision turning) was examined from a diameter of 60 mm up to 67.2 mm in three steps. The experimental tests were performed on a Gildemeister CTX Gamma 1250 TC with an already existing workpiece configuration of preceding research works [8], shown in Figure 4. The workpieces are made of EN-GJS-600-3 as already applied for the theoretical calculations.…”

Poly-crystalline diamond (PCD) is an extremely tough, synthetically produced cutting tool material, which offers outstanding capabilities concerning wear behavior in abrasive cutting environments. Currently, the primary application of PCD cutting tools is the machining of non-ferrous materials, as the diamond’s carbon high affinity towards iron causes diffusion effects while cutting steel with rising temperature. This effect significantly reduces tool life. To lower the occurring temperature of the cutting process, and therefore avoid the reaction of carbon and iron, a thermal functionalization of the cutting inserts has been investigated. The results give insight into making PCD cutting tools economically usable for the machining of iron-carbon materials.

Near–dry machining and dry machining lead to increased temperature of the cutting tools. To reduce tool wear and extend the tool lifetime, and, eventually, to keep the accuracy of manufactured parts within acceptable limits as long as possible, a sustainable cooling technique is required. The technology of internal cooling of the cutting tool appears to be the most promising, because it allows eliminating the presence of the coolant on the manufacturing part and delivers the heat–transferring fluid to the very cutting area of the tool. This paper provides a literature review on the closed–loop internally cooled cutting tools (CLICCT) for turning. The current level of knowledge and experimental machining with prototypes has proven that CLICCT can utilize the benefits of dry cooling, having a longer tool life.
