Analysis of Micro Burr Formation in Austenitic Stainless Steel X5CrNi18-10

This paper presents the results on the analysis of micro-burr formation for slot milling of austenitic stainless steel X5CrNi18-10. Two-fluted submicron grain cemented carbide tools with a diameter of d = 0.5 mm were used. Applying cutting speeds from vc = 100 m/min to vc = 200 m/min and feeds per tooth from fz = 6 μm to fz = 8 μm the influence of these parameters on the burr formation was investigated. Additionally the effect of the lubrication method – minimum quantity lubrication, flood lubrication and bath lubrication – on the burr formation was analysed.
