A built-up-edge is formed while machining __________

A built-up-edge is formed while machining __________ Correct Answer ductile materials at low speed

When machining ductile materials, conditions of high local temperature and extreme pressure in the cutting zone and also high friction in the tool chip interface, may cause the work material to adhere or weld to the cutting edge of the tool forming the built-up edge. Low-cutting speed contributes to the formation of the built-up edge. Increasing the cutting speed, increasing the rake angle and using a cutting fluid contribute to the reduction or elimination of built-up edge.
