Prognozowanie okresu trwałości ostrza w obróbce na sucho stali nierdzewnej duplex

This paper examines the influence of cutting parameters, namely cutting speed, feed and depth of cut onto tool life in DSS turning process. The study included developing a mathematical model to determine the tool life. Verification research has been carried out on CNC lathe, hence the test plan has been adjusted to the possibility of programmable machines controlling GE Fanuc series 0 - T. The comparison of results obtained by given experimental plan was performed in industrial company.W artykule przedstawiono wpływ parametrów obróbki, a mianowicie prędkości skrawania, posuwu i głębokości skrawania na okres trwałości ostrza w procesie toczenia stali duplex. Badania obejmowały opracowanie modelu matematycznego dla określenia okresu trwałości ostrza skrawającego. Badania weryfikacyjne wykonywano na tokarce sterowanej numerycznie, stąd plan badań dostosowany został do możliwości programowych maszyny ze sterowaniem GE Fanuc seria 0 - T. Porównanie wyników przeprowadzono w warunkach produkcyjnych

Roughness Parameters Calculation By Means Of On-Line Vibration Monitoring Emerging From AWJ Interaction With Material

The paper deals with a study of relations between the measured Ra, Rq, Rz surface roughness parameters, the traverse speed of cutting head v and the vibration parameters, PtP, RMS, vRa, generated during abrasive water jet cutting of the AISI 309 stainless steel. Equations for prediction of the surface roughness parameters were derived according to the vibration parameter and the traverse speed of cutting head. Accuracy of the equations is described according to the Euclidean distances. The results are suitable for an on-line control model simulating abrasive water jet cutting and machining using an accompanying physical phenomenon for the process control which eliminates intervention of the operator
