4. Conclusion

Cutting materials have evolved and progressed significantly in recent years. Given the technical, economic, and geopolitical difficulties in accessing raw materials, one of the major challenges for the coming years will be the development of materials based on new compounds (for example, cutting material manufacturers have been working for several years on replacing cobalt).

Development trends are also focused on improving existing materials in order to increase their potential applications. For example, some suppliers have recently developed diamonds that are compatible with steel machining, which was impossible just a few years ago.

Emerging machining assistance processes such as supercritical CO₂ may lead to changes in cutting materials, particularly carbides, to make them more resistant to the cold generated by this process.
