What is Stripping Force and Why Should You Care?
Stripping Force is essentially the total shear force that acts on the thickness of an object being cut. Imagine you're cutting through a thick apple with a knife—the force it takes to slice through the apple and pull the knife back out is akin to Stripping Force. Typically, this force is about 10-20% of the Cutting Force.
Why should you care about Stripping Force? If you don't calculate it properly, you can end up with problems. Too much force can break your tools or deform your parts. Too little, and you might not get a clean cut or strip. Calculating it accurately ensures you pick the right tools, settings, and parameters to optimize efficiency and safety in your machining operations.
How to Calculate Stripping Force
Calculating the Stripping Force follows a specific formula:
[\text{Stripping Force} = \frac{\text{Cutting Force} \times \text{Stripping Percentage}}{100}]
Where:
- Stripping Force is the force required to strip the material in Newtons (N)
- Cutting Force is the total force applied during the cutting process in Newtons (N)
- Stripping Percentage is the percentage of the cutting force involved in stripping (usually 10-20%)
In a nutshell, you multiply the Cutting Force by the percentage of it that goes into stripping, then divide by 100.
Calculation Example
Suppose you have a cutting force of 40 N, and the percentage of the cutting force involved in stripping is 12%. How do you find the Stripping Force?
Plug your numbers into the formula:
[\text{Stripping Force} = \frac{40 \text{ N} \times 12}{100}]
[\text{Stripping Force} = \frac{480}{100}]
[\text{Stripping Force} = 4.8 \text{ N}]
The Stripping Force in this example is 4.8 N.
