This study aims to determine the extent to which coating composition and workpiece properties impact machinability and tool selection when turning Compacted Graphite Iron (CGI) under extreme roughing conditions. Two CGI workpieces. differing in pearlite content and graphite nodularity. were machined at a cutting speed of 180 m/min. https://hollandscountryclothinges.shop/product-category/bridle-bags/
