Abstract This paper concerns the tool wear in hard turning of AISI 52100 hardened steel by means PCBN tools. The purposes this work are development a model and its implementation FEM-based procedure for predicting crater flank progression during machining operations studying influence on process terms geometry modifications stress variation tool. developed model, able to update worn as function...

In this paper, the improvement of characteristics different steels that are subjected to extreme operating conditions, including used in manufacture various military components, AISI 52100, bearings, and other types parts also severe conditions were analyzed regarding cold spraying, which uses powders increase performance materials. The cold, thermal spraying technology “Cold Spray” is a method...

Gaseous carbonitriding of AISI 52100 steel was investigated under various processing conditions. The process parameters studied involve ammonia content (2.5–7.5 vol%), carbon potential (0.8–1.2%), and temperature (780–880 °C). carbon/nitrogen concentration-depth profiles that developed during were determined by light element analysis. microstructural residual stress evolution, the thermal-mecha...

Abrasive machining is one of the most non-conventional processes for finishing. It is widely used in industry to machine the materials like mild steel, aluminum, copper, titanium, glass, hard rock material, graphite, composite material, ceramics etc.Like in abrasive jet machining. This technique uses jet which contains abrasive material. Now a day water-magnetic abrasive machining is one of the...
