Helix tools

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.

E. Plastic deformation  Deformation at the edge. Caused by weakening of the cutting tool due to overheating, which reduces its resistance to external impact.

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

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.

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.

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.
