Back Chip Temperature in Environmentally Conscious Turning with Conventional and Internally Cooled Cutting Tools

Back Chip Temperature in Environmentally Conscious Turning with Conventional and Internally Cooled Cutting Tools

Central to machining processes is the interaction between the tool insert and the chip of material removed from the blank. Chip-insert interaction occurs when the chip slides on the rake face of the insert. Heat is generated by the friction inherent to this sliding process. The temperature in the cu...
