Insert edge problems
To achieve optimized cutting data, best possible workpiece quality and tool life, always remember to check the insert edge. At low speeds, built-up edge (BUE) and chipping are the main insert edge problems; at high speeds, plastic deformation (PD), flank wear and crater wear are the main problems. The solutions are presented in the following table.

When parting to centre and on stainless material, it is almost impossible to avoid BUE. It is important to minimize this phenomenon by using the solutions above. | |||
