Abstract
The use of high pressure coolant supply results in a significant reduction in the tool-chip contact length, and hence the contact area. The reduction in tool-chip contact length and contact area with little change in the cutting forces will increase the compressive stress at the tool edge. The high pressure coolant supply reduces the temperature at the tool cutting edge when machining Inconel 901. The inserts were mainly rejected because of notching which is the result of the increase in compressive stresses at the tool edge due to the high pressure coolant jet. This may promote an increase in work hardening. The subsequent displacement of the work hardened layer towards the depth-of-cut-line and the consequent formation of a burr results in shorter tool life.
