How to Calculate Tool Changing Time given Optimum Spindle Speed?
Tool Changing Time given Optimum Spindle Speed calculator uses Time to Change One Tool = Reference Tool Life/((Rotational Frequency of Spindle*2*pi*Outer Radius of 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/Machining and Operating Rate to calculate the Time to Change One Tool, The Tool Changing Time given Optimum Spindle Speed is a method to determine the maximum time that can be spared on each tool to be spent for changing such that the production cost is minimum. Time to Change One Tool is denoted by tc symbol.
How to calculate Tool Changing Time given Optimum Spindle Speed using this online calculator? To use this online calculator for Tool Changing Time given Optimum Spindle Speed, enter Reference Tool Life (Tref), Rotational Frequency of Spindle (ns), Outer Radius of Workpiece (Ro), Reference Cutting Velocity (Vref), Taylor's Tool Life Exponent (n), Workpiece Radius Ratio (ar), Cost of a Tool (Ct) & Machining and Operating Rate (M) and hit the calculate button. Here is how the Tool Changing Time given Optimum Spindle Speed calculation can be explained with given input values -> 0.000231 = 300/((10*2*pi*0.025/0.0833333333333333)^(1/0.5)*(1-0.45^((1+0.5)/0.5))*(1-0.5)/((1+0.5)*(1-0.45)))-70/100.
