Abstract
Surface engineering is important for carried out to improve the quality of the surface layer of the material. It is important that in special applications of corrosion resistant steel, low surface roughness is obtained. Duplex stainless steel is becoming more widely used for example in the petrochemical industry or shipbuilding. Duplex stainless steel is a material classified as difficult-to-cut. It is therefore important to investigate the impact of machining parameters on the durability and wear of a cutting tool. In the paper has determined the influence of variables machining: feed rate, depth of cut, cutting speed, on the maximum tool flank wear. Surface machining was carry out with carbide tipped inserts. The criterion of the smallest roughness and the highest wear was proposed.

Stainless steels currently enjoy high interest shows that every year takes place a few percent increase in production
After turning finishing duplex stainless steel, it was determined that the machining parameters affect the surface quality and knife wear
Even smaller values of the Ra = 1.05 m parameter were determined for the cutting parameters: feed rate of f = 0.1 mm/rev, with a constant cutting speed vc = 70 m/min and depth of cut ap=0.5mm, using a CCMT 09T304-UM cutting insert carbides of the 2025 grade with a CVD Ti(C,N)/Al2O3/TiN
Summary
Stainless steels currently enjoy high interest shows that every year takes place a few percent increase in production. Cutting parameters were selected based on own research for longitudinal turning: feed rate f = 0.1 ÷ 0.2 mm/rev, depth of cut ap = 0.5 mm, cutting speed vc = 50 ÷ 100 m/min, on the maximum tool flank wear VB.
