Cutting conditions in cermate and tungsten carbide inserts

The performance of turning operations depends on tool life and material removal rate (MRR). AISI P20 material is commonly used in die manufacturing, with tungsten carbide inserts being the standard choice for turning. However, modern industries demand higher productivity, requiring better tool life and MRR under similar parameters. Cermet inserts, a combination of ceramic and metal materials, address these requirements effectively. This investigation experimentally compares tungsten carbide and cermet inserts for turning AISI P20 material to identify the most suitable insert for enhanced performance.
