In this study, high-speed steel cutting tools after cryogenic treatment on cutting SUS 316 stainless steel milling it and tool wear affect the characteristics for analysis, cutting parameters using numerical control milling machine set spindle speed, feed rate, cutting depth, cutting width of SUS 316 stainless steel milling . The cutter was Nachi 4SE HSS-Co high-speed steel four-blade end mill, where tool diameters ø 6 mm, ø 8 mm, ø 10 mm three kinds of tool diameter, explore the tool cryogenic treatment, no cryogenic treatment of SUS 316 stainless steel milling process Characteristics.
The experimental results, the use of sophisticated electronic weighing before and after the milling tool weight measured before and after the investigation milling tool wear. After the measurements were milling length 200 mm, 400 mm, 600 mm tool weight were measured, after measuring the weight before milling workpiece measuring parts in weight after milling, in the calculation of the workpiece weight difference before and after. Stainless steel part using a surface roughness tester roughness measurement data integration tool wear angle section with an optical microscope to measure tool wear angle and width measurement tool wear, super cool place to explore the tool in the tool-free angle between the two super-cold treatment abrasion and wear width difference, then the data from the study Integration of high-speed steel cold treatment and no cryogenic treatment on tool wear.
Keywords: high-speed steel, cryogenic treatment, tool wear
