What is Flank Surface in Cutting Tool? Principal

A cutting tool may have one or more flank surfaces. It is worth noting that total number of flank surfaces present in a cutting tool depends on the number of cutting edges. A single point cutter contains only one flank surface; while, a multi-point cutter contains multiple (equals to number of cutting edges) flank surfaces. Therefore, for every

Tool Wear: Meaning, Types and Causes Metal Cutting

Crater wear, flank wear (or wear land formation) and chipping of cutting edge affect performance of the cutting tool in various ways. Crater wear may, however under certain circumstances, reduce forces by effectively increasing the rake angle of the tool. Clearance face (Flank or wear-land) wear and chipping almost invariably increase the cutting forces due to increased rubbing forces.

With normal flank wear, a uniform wear scar will form along the insert's cutting edge. Occasionally, metal from the workpiece smears over the cutting edge and exaggerates the apparent size of the wear scar on the insert. Rapid flank wear, which looks the same as normal wear, is undesirable because it reduces tool life and time in the cut.
