3. Machined material properties and machinability

3.1 Importance of the problem

The materials used for the machined parts were selected according to their final destination.

But the composition of a steel, for example (structure, additional elements) affects its machinability.

Numerous metals with "improved machinability" have been developed to reduce cutting time (increase in v _c and f ), reduce downtime (less frequent tool changes) and improve machining quality (lower roughness, in particular), while maintaining the functional characteristics of the manufactured part.

This is important in the highly competitive field of machining, where manufacturers need to optimize their production.
