How to Calculate Optimum Spindle Speed?
Optimum Spindle Speed calculator uses Rotational Frequency of Spindle = (Reference Cutting Velocity/(2*pi*Outer Radius of Workpiece))*((((1+Taylor's Tool Life Exponent)*Cost of a Tool*Reference Tool Life*(1-Workpiece Radius Ratio))/((1-Taylor's Tool Life Exponent)*(Cost of a Tool*Time to Change One Tool+Cost of a Tool)*(1-(Workpiece Radius Ratio^((1+Taylor's Tool Life Exponent)/Taylor's Tool Life Exponent)))))^Taylor's Tool Life Exponent) to calculate the Rotational Frequency of Spindle, The Optimum Spindle Speed refers to the rotational frequency of the spindle of the working Tool that results in the minimum Production Cost of Facing. Rotational Frequency of Spindle is denoted by ns symbol.
How to calculate Optimum Spindle Speed using this online calculator? To use this online calculator for Optimum Spindle Speed, enter Reference Cutting Velocity (Vref), Outer Radius of Workpiece (Ro), Taylor's Tool Life Exponent (n), Cost of a Tool (Ct), Reference Tool Life (Tref), Workpiece Radius Ratio (ar) & Time to Change One Tool (tc) and hit the calculate button. Here is how the Optimum Spindle Speed calculation can be explained with given input values -> 0.005088 = (0.0833333333333333/(2*pi*10))*((((1+0.512942)*70*300*(1-0.45))/((1-0.512942)*(70*36+70)*(1-(0.45^((1+0.512942)/0.512942)))))^0.512942).
