Roughness value given corner radius Solution

STEP 0: Pre-Calculation Summary

Formula Used

Roughness Value = 0.0321*(Feed)^2/Corner Radius of Tool
R = 0.0321*(f)^2/r_c
This formula uses 3 Variables

Variables Used

Roughness Value - (Measured in Meter) - Roughness Value is the arithmetic average of the absolute values of the roughness profile ordinates.
Feed - (Measured in Meter) - The Feed is the distance as the cutting tool advances along the length of the work for every revolution of the spindle.
Corner Radius of Tool - (Measured in Meter) - The Corner Radius of Tool is a measurement describing the curve on the corners of labels.

STEP 1: Convert Input(s) to Base Unit

Feed: 0.9 Millimeter --> 0.0009 Meter (Check conversion here)
Corner Radius of Tool: 1.523466 Millimeter --> 0.001523466 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

R = 0.0321*(f)^2/r_c --> 0.0321*(0.0009)^2/0.001523466

Evaluating ... ...

R = 1.70670037926675E-05

STEP 3: Convert Result to Output's Unit

1.70670037926675E-05 Meter -->0.0170670037926675 Millimeter (Check conversion here)

FINAL ANSWER

0.0170670037926675 ≈ 0.017067 Millimeter <-- Roughness Value

< Cutting Force and Surface Roughness Calculators

Cutting Force given Specific Cutting Energy in Machining

Go Cutting Force = Specific Cutting Energy in Machining*Cross Sectional Area of Uncut Chip

Cutting Force given Rate of Energy Consumption during Machining

Go Cutting Force = Rate of Energy Consumption during Machining/Cutting Speed

Resultant Cutting Force using Force required to remove Chip

Go Resultant Cutting Force = Force required to Remove Chip+Plowing Force

Force required to remove Chip and Acting on Tool Face

Go Force required to Remove Chip = Resultant Cutting Force-Plowing Force

Roughness value given corner radius Formula

Roughness Value = 0.0321*(Feed)^2/Corner Radius of Tool
R = 0.0321*(f)^2/r_c

How does the corner radius of the tool influence the surface roughness?

The larger corner radius of the main cutting edge leads to the increase of tool life, to the decrease of cutting forces and to the decrease of surface roughness indices.

How to Calculate Roughness value given corner radius?

Roughness value given corner radius calculator uses Roughness Value = 0.0321*(Feed)^2/Corner Radius of Tool to calculate the Roughness Value, Roughness value given corner radius refers to the surface roughness of the material after a machining process that involves a corner radius. Surface roughness, often represented by Ra is a measure of the texture of the surface and is generally determined by the machining parameters and the tool geometry. Roughness Value is denoted by R symbol.

FAQ

What is Roughness value given corner radius?

Roughness value given corner radius refers to the surface roughness of the material after a machining process that involves a corner radius. Surface roughness, often represented by Ra is a measure of the texture of the surface and is generally determined by the machining parameters and the tool geometry and is represented as R = 0.0321*(f)^2/r_c or Roughness Value = 0.0321*(Feed)^2/Corner Radius of Tool. The Feed is the distance as the cutting tool advances along the length of the work for every revolution of the spindle & The Corner Radius of Tool is a measurement describing the curve on the corners of labels.

How to calculate Roughness value given corner radius?

Roughness value given corner radius refers to the surface roughness of the material after a machining process that involves a corner radius. Surface roughness, often represented by Ra is a measure of the texture of the surface and is generally determined by the machining parameters and the tool geometry is calculated using Roughness Value = 0.0321*(Feed)^2/Corner Radius of Tool. To calculate Roughness value given corner radius, you need Feed (f) & Corner Radius of Tool (r_c). With our tool, you need to enter the respective value for Feed & Corner Radius of Tool and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.

How many ways are there to calculate Roughness Value?

In this formula, Roughness Value uses Feed & Corner Radius of Tool. We can use 3 other way(s) to calculate the same, which is/are as follows -

Roughness Value = Feed/(4*(cot(Working Major Cutting Edge Angle)+cot(Working Minor Cutting Edge)))
Roughness Value = (0.0642*(Feed Speed)^2)/(Diameter of Cutter*(Rotational Frequency of Cutter)^2)
Roughness Value = 0.0321*(Feed)^2/Corner Radius of Tool
