End M ill End M ill Technical information i Trochoidal milling High Feed Milling - Milling strategy developed to reduce chip thickness by using a tool with a special face geometry. This kind of a tool allows machining with several times higher feed rates than conventional machining. Very small milling width ae and small wrap angle of the tool - reduction of chip thickness hex and radial forces Highest possible cutting speed Vc and number of flutes - high feed speeds and productivity Full length of cutting edges in use – even wear of cutting edges Tool path Tool path Milling a groove in a full material Trochoidal milling HFM - High Feed Milling High Feed Milling - Milling strategy developed to reduce chip thickness by using a tool with a special face geometry. This kind of a tool allows machining with several times higher feed rates than conventional machining. Very low cutting depth ap - reduced chip thickness hex and radial forces Large cutting width ae and feed per tooth fz - even wear of the specially shaped cutting edge Highest possible feed per tooth and number of teeth - high feed speeds and productivity Face of standard end mill Face of milling cutter Comparison of the chip for High Feed Milling shape with the same feed per tooth Machine requirements: High speed spindle High dynamics of the machine - frequent changes of direction and feed values Balancing tools with a tool holder Necessity to be able to program the toolpath - CAM softwareProper tool design 12 327
