Dry milling of the ultra-high-strength steel 30CrMnSiNi2A with coated carbide inserts

The superior mechanical and physical properties of ultra-high strength steel 30Cr3SiNiMoVA have awarded the material such desirable and increasing demands in aerospace and aviation industries. Due to its excellent properties, 30Cr3SiNiMoVA is usually classified as a difficult-to-cut material. The machining process of ultra-high strength steel is often characterized by high cutting forces, low surface finish and severe tool wear. In actual production, hard cutting which is a profitable alternative to finish grinding is usually employed in order to improve machining efficiency and reduce processing cost. Therefore, this research concerns the machinability evaluation in hard milling of 30Cr3SiNiMoVA by using TiAlN coated carbide tools. The machinability of the steel was investigated with respect to cutting forces, surface roughness, chip morphology and tool wear, respectively. Finally, a comparative test was also conducted between hard milling and grinding process. The results pointed out that hard milling and coated tools were suitable, beneficial and effective for manufacturing ultra-high strength steel 30Cr3SiNiMoVA.

Coated Carbide

Ultra-high strength steel 30Cr3SiNiMoVA is a typical difficult-to-cut material. During the machining process of 30Cr3SiNiMoVA, tool wear is an important factor which needs to be investigated seriously. In this work, one kind of CVD coated tools was used to investigate the tool wear mechanism of face milling of Ultra-high Strength Steel 30Cr3SiNiMoVA. Cutting forces during the wear process were measured with a kistler dyna-mometer. Surface roughness and tool wear evolution were determined.
