Analysis of the Lubrication Performance of Low-Carbon Steel Sheets in the Presence of Pressurised Lubricant

Abstract In sheet metal forming processes, friction increases the force parameters of process and produces a deterioration in quality surface components. The basic way to reduce unfavourable impact is lubricate with commercial oils. This article presents results experimental studies analysis variance (ANOVA) DC01 low-carbon steel sheets using strip drawing test. For these tests, special device was built containing countersamples flat made 145Cr6 covered protective AlTiN coating. Lubricants different viscosities were fed into contact zone under forced pressure. effect pressure on value coefficient also determined. predicted R² 0.9227 reasonable agreement adjusted 0.9411 confirming that ANOVA model reliable. It found increasing lubricant had beneficial reducing friction. higher pressure, more effectively pressurised oil reduced
