Flankwear

Cutting tool wear The edge of a cutting tool wears down during machining which impairs the ability to achieve the desired tolerances and consistent quality.

C. Notch wear Streaked wear on the bottom of the edge. Caused by mechanical abrasion from harder workpieces which, in the same way as crater wear, occurs due to hard particle diffusion. If a larger notch occurs among the smaller ones, it is probably due to the surface deformation from a previous cuttin pass. The notches can also appear on the rake side of the insert.

D. Comb cracks  Small cracks across the edge. Caused by repeated thermal changes that cause the material to expand and contract, which leads to cracks and subsequent chipping.

A. Crater wear Crater-shaped wear on the cutting edge of the insert. Caused by mechanical abrasion when hard particles in the chip, eg oxides or carbides, meet the cutting surface. Diffusion between the material and the insert accelerates the formation of the crater wear.

B. Flank wear Smooth wear on the flank of the insert. Caused by mechanical abrasion which, similar to crater wear, occurs due to wear from hard particles.

Types of tool wearpdf

Cutting forces The wear is strongly associated with the cutting forces that a cutting insert is subjected to, which are a result of the tool's design, the angle of the tool holder, the cutting speeds, the choice of material, vibrations etc. Actual cutting forces are thus impossible calculate.

The cause of tool wear can be divided into the following types, that individually or in combination, will inevitably require a tool change.
