Dec 29, 2009 i took a series of machining classes at a community college in ca years ago. the simple guidance given for cutting steel with hss was 100sfm at the largest diameter. approximating pi allows the simple formula of 4 x cutting speed (sfm) / diameter (inches). for form cutters like your ball endmill, the recommendation was to cut that rpm in.
Different liner designs at different mill speed but with constant filling degree (30%). indeed, as explained previously, at a mill stop, the measurement of ball charge filling degree could be undertaken and will provide the static media charge angle (βstatic = 143 ). an online measurement of the similar angle (βdynamic), when the mill is.
