How to Calculate Reference Cutting Velocity given Optimum Spindle Speed?
Reference Cutting Velocity given Optimum Spindle Speed calculator uses Reference Cutting Velocity = Rotational Frequency of Spindle*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 Reference Cutting Velocity, The Reference Cutting Velocity given Optimum Spindle Speed is a method to determine the Cutting Velocity for the reference condition when the Facing Operation has to be finished at minimum expense. Reference Cutting Velocity is denoted by Vref symbol.
How to calculate Reference Cutting Velocity given Optimum Spindle Speed using this online calculator? To use this online calculator for Reference Cutting Velocity given Optimum Spindle Speed, enter Rotational Frequency of Spindle (ns), 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 Reference Cutting Velocity given Optimum Spindle Speed calculation can be explained with given input values -> 3E+9 = 0.050885*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).
