TURNINGTAPPINGHOLEMAKINGSOLID END MILLINGINDEXABLE MILLING High-Performance Solid Carbide End Mills Trochoidal Milling TTDifferences between hm and hx In conventional milling, it makes sense to calculate the load to the cutting edge through hm. With reducing the ae to very low values, you can calculate with the maximum chip thickness hx to make sure that the feed per tooth is set up correctly. Conventional Smart Machining hm = 360º/p∙fs∙ae/D∙fz∙sin x hx = 360º/p∙fs∙2∙ae/D∙fz∙sin x hm [mm] = average chip thickness hx [mm] = maximum chip thickness fs [°] = engagement angle fs [°] = engagement angle ae [mm] = width of engagement ae [mm] = width of engagement D1 [mm] = outer diameter tool D1 [mm] = outer diameter tool fz [mm] = feed per tooth fz [mm] = feed per tooth c [°] = lead angle c [°] = lead angle l [°] = helix angle * l [°] = helix angle * * Solid End Mills: c = 90°-l Trochoidal Milling can be performed with solid or indexable milling tools. widia.com B57
