Hi Don, I am trying to calculate for the hob rpm. Using the sfm for the material I want to cut, 70 sfm.(Found in machinists ready reference). What would the formula be to find hob rpm? I only have a few choices on my machine but I would like to get as close as I could for the best cutting performance and production times. Thank you. Tim
