Rotational Frequency of Workpiece given Roughness Solution

STEP 0: Pre-Calculation Summary

Formula Used

Rotational Frequency of Spindle = 0.18*Length of Workpiece/(Machining Time*(Corner Radius of Tool*Roughness Value)^0.5)
n_w = 0.18*L/(t_m*(r_E*R_a)^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) - 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: 400 Millimeter --> 0.4 Meter (Check conversion here)
Machining Time: 0.74 Minute --> 44.4 Second (Check conversion here)
Corner Radius of Tool: 1.5 Millimeter --> 0.0015 Meter (Check conversion here)
Roughness Value: 0.017531 Millimeter --> 1.7531E-05 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

n_w = 0.18*L/(t_m*(r_E*R_a)^0.5) --> 0.18*0.4/(44.4*(0.0015*1.7531E-05)^0.5)

Evaluating ... ...

n_w = 10.0000127083576

STEP 3: Convert Result to Output's Unit

10.0000127083576 Hertz --> No Conversion Required

FINAL ANSWER

10.0000127083576 ≈ 10.00001 Hertz <-- Rotational Frequency of Spindle

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.
