This formula uses 5 Variables

Variables Used

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.
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.
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.
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)
Rotational Frequency of Spindle: 10 Hertz --> 10 Hertz No Conversion Required
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

t_m = 0.18*L/(n_w*(r_E*R_a)^0.5) --> 0.18*0.4/(10*(0.0015*1.7531E-05)^0.5)

Evaluating ... ...

t_m = 44.4000564251076

STEP 3: Convert Result to Output's Unit

44.4000564251076 Second -->0.740000940418459 Minute (Check conversion here)

FINAL ANSWER

0.740000940418459 ≈ 0.740001 Minute <-- Machining Time
