Threading feed rate
WebJan 2, 2024 · Is it possible in Mastercam 2024 (Lathe Toolpath) to change feed rate for the last final pass on a Finish tool pass or do you need to manually edit the NC post file or run/chain another finish pass? Example: 5 final passes, removing .010" each at feed rate of .003/rpm and want final 5th pass at .001"/rpm in order to achieve adequate surface finish. By dividing the full cutting depth of the thread into smaller cuts, the sensitive nose radius of the insert is not overloaded. Example: By taking 0.23–0.10 mm (0.009–0.004 inch) in cutting depth per pass (radial infeed), the full cutting depth (ap) and the profile depth of the thread (0.94 mm (0.037 inch)) are … See more d = Major diameter, external D = Major diameter, internal d1= Minor diameter, external D1= Minor diameter, internal d2= Pitch diameter, external D2= Pitch … See more The lead angle, φ, (helix angle) is dependent on and related to the diameter and the pitch of the thread. This measurement can be represented by a triangle being … See more
