Rotational Frequency of Spindle given Machining Time for Facing Solution

STEP 0: Pre-Calculation Summary
Formula Used
Rotational Frequency of Spindle = (Outside Radius of the Workpiece-Inner Radius of Workpiece)/(Machining Time*Feed)
ns = (ro-ri)/(tm*f)
This formula uses 5 Variables
Variables Used
Rotational Frequency of Spindle - (Measured in Hertz) - Rotational Frequency of Spindle is the number of turns made by the spindle of the Machine for cutting in one second.
Outside Radius of the Workpiece - (Measured in Meter) - Outside Radius of the Workpiece is the radius of the outermost surface of the workpiece, away from the machining tool.
Inner Radius of Workpiece - (Measured in Meter) - The Inner Radius of Workpiece is the radius of the innermost surface of the workpiece.
Machining Time - (Measured in Second) - Machining Time is the time when a machine is actually processing something. Generally, machining time is the term used when there is a removal of unwanted material.
Feed - (Measured in Meter) - The Feed is the distance the cutting tool advances along the length of the work for every revolution of the spindle.
STEP 1: Convert Input(s) to Base Unit
Outside Radius of the Workpiece: 1000 Millimeter --> 1 Meter (Check conversion here)
Inner Radius of Workpiece: 946 Millimeter --> 0.946 Meter (Check conversion here)
Machining Time: 0.75 Minute --> 45 Second (Check conversion here)
Feed: 0.9 Millimeter --> 0.0009 Meter (Check conversion here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
ns = (ro-ri)/(tm*f) --> (1-0.946)/(45*0.0009)
Evaluating ... ...
ns = 1.33333333333333
STEP 3: Convert Result to Output's Unit
1.33333333333333 Hertz --> No Conversion Required
FINAL ANSWER
1.33333333333333 1.333333 Hertz <-- Rotational Frequency of Spindle
(Calculation completed in 00.004 seconds)
