CLOSING COST ONLINE CALCULATION TOOL HOW TO
How to calculate Tool Changing Cost in terms of Optimum Spindle Speed using this online calculator? To use this online calculator for Tool Changing Cost in terms of Optimum Spindle Speed, enter Machining and Operating Rate (M), Reference Tool Life (T ref), Rotational Frequency of Spindle (n s), Outside Radius of the Workpiece (r o), Reference Cutting Velocity (V ref), Taylor's Tool Life Exponent (n), Workpiece Radius Ratio (a r) and Cost of a Tool (C t) and hit the calculate button.
Cost of changing each Tool and is denoted by C CT symbol. Tool Changing Cost in terms of Optimum Spindle Speed calculator uses cost_of_changing_each_tool = ( Machining and Operating Rate* Reference 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 in terms of 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. How to Calculate Tool Changing Cost in terms of Optimum Spindle Speed? Cost of a Tool- The Cost of a Tool is simply the cost of one tool being used for machining. Workpiece Radius Ratio- Workpiece Radius Ratio is the ratio of the inner radius of the workpiece to its outer radius. (Measured in Meter per Minute) Taylor's Tool Life Exponent- Taylor's Tool Life Exponent is an experimental exponent that helps in quantifying the rate of Tool Wear. (Measured in Meter) Reference Cutting Velocity - Reference Cutting Velocity is the Cutting Velocity of the tool used in the reference Machining Condition.
(Measured in Hertz) Outside Radius of the Workpiece - Outside Radius of the Workpiece is the radius of the outermost surface of the workpiece, away from the machining tool. (Measured in Day) Rotational Frequency of Spindle - Rotational Frequency of Spindle is the number of turns made by the spindle of the Machine for cutting in one second. Reference Tool Life - Reference Tool Life is the Tool Life of the tool obtained in the reference Machining Condition. Variables Used Machining and Operating Rate- Machining and Operating Rate is the money charged for processing on and operating machines per unit time, including overheads.
