ns = 0.18*L/(tm*((rE*Ra)^0.5))
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.
Length of Workpiece - (Measured in Meter) - Length of Workpiece is the measurement or extent of Workpiece from end to end in the direction of Cut.
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.
Corner Radius of Tool - (Measured in Meter) - The Corner radius of tool is a measurement describing the curve on the corners of your labels.
Roughness Value - (Measured in Meter) - Roughness Value is the arithmetic average of the absolute values of the roughness profile ordinates.
STEP 1: Convert Input(s) to Base Unit
Length of Workpiece: 0.4 Meter --> 0.4 Meter No Conversion Required
Machining Time: 0.75 Minute --> 45 Second (Check conversion here)
Corner Radius of Tool: 1.5 Millimeter --> 0.0015 Meter (Check conversion here)
Roughness Value: 17.067 Micrometer --> 1.7067E-05 Meter (Check conversion here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
ns = 0.18*L/(tm*((rE*Ra)^0.5)) --> 0.18*0.4/(45*((0.0015*1.7067E-05)^0.5))
Evaluating ... ...
ns = 9.99990234518049
STEP 3: Convert Result to Output's Unit
9.99990234518049 Hertz --> No Conversion Required
FINAL ANSWER
9.99990234518049 9.999902 Hertz <-- Rotational Frequency of Spindle
(Calculation completed in 00.004 seconds)

How is Roughness measured?

With a contact-type roughness meter, surface roughness is measured by tracing the probe across the surface of the target. In contrast, a laser-based non-contact roughness meter emits a laser beam onto the target and detects the reflected light to measure the roughness.
