How to Calculate Tool Changing Cost given Optimum Spindle Speed?
Tool Changing Cost given Optimum Spindle Speed calculator uses Cost of changing each Tool = (Cost of a Tool*Maximum Tool Life/(((Rotational Frequency of Spindle*2*pi*Outside Radius of the Workpiece/Reference Cutting Velocity)^(1/Taylor's Tool Life Exponent))*(1-(Workpiece Radius Ratio^((1+Taylor's Tool Life Exponent)/Taylor's Tool Life Exponent)))*(1-Taylor's Tool Life Exponent)/((1+Taylor's Tool Life Exponent)*(1-Workpiece Radius Ratio))))-Cost of a Tool to calculate the Cost of changing each Tool, The Tool Changing Cost given Optimum Spindle Speed is a method to determine the cost that arises due to the time taken by the operator in changing 1 Cutting Tool such that the production cost is minimum. Cost of changing each Tool is denoted by CCT symbol.
How to calculate Tool Changing Cost given Optimum Spindle Speed using this online calculator? To use this online calculator for Tool Changing Cost given Optimum Spindle Speed, enter Cost of a Tool (Ct), Maximum Tool Life (Tmax), Rotational Frequency of Spindle (ns), Outside Radius of the Workpiece (ro), Reference Cutting Velocity (Vref), Taylor's Tool Life Exponent (n) & Workpiece Radius Ratio (ar) and hit the calculate button. Here is how the Tool Changing Cost given Optimum Spindle Speed calculation can be explained with given input values -> -69.932938 = (70*420000/(((10*2*pi*1/0.0833333333333333)^(1/0.5))*(1-(0.45^((1+0.5)/0.5)))*(1-0.5)/((1+0.5)*(1-0.45))))-70.
