Looking for speed feed calculators and recommendations for your Dapra tooling. ### Common Formulas For Milling Operations Speed Feed

Milling Formulas. Speed (RPM) = (SFM x 3.82) D. Feed (IPM) = RPM x FPT x Z. SFM (Surface Feet per Minute) = (RPM x D) 3.82. IPT (Inches per Tooth) = (IPM RPM) Z. MRR (Cubic Inches per Minute) = IPM WOC DOC. AFPT (@ less than 1 2 dia. WOC) = IPM x sqroot of (D WOC) HP (Horsepower Consumption) = MRR x mf. mf - steel = 1. ### Dropping A Ball And Calculating Its Speed Physics

Aug 07, 2014 If the acceleration is -9.8 m s^2 then the speed after t seconds is v= 9.8t+ v0 (v0 is the initial speed and I am taking positive downward) and then the distance traveled is s= 4.8t^2+ v0t. Since the ball is dropped the initial speed is 0 so we have v= 9.8t and s= 4.8t^2. Since the ball falls 50m, solve 4.8t^2= 50 to find t. ### Best Way To Determine The Ball
