# Surface Finish Calculator

Introduction

Calculating surface finish is crucial in various industries, as it directly impacts the quality and performance of a product. To simplify this process, we’ll introduce a Surface Finish Calculator.

**How to Use**

The Surface Finish Calculator is user-friendly. Follow these steps:

- Input the required parameters in the designated fields.
- Click the “Calculate” button to obtain the surface finish result.

**Formula**

The formula used for surface finish calculation is:

Where:

*Ra* is the average roughness.*A*is a constant based on the material.*f*is the feed rate.*n*is the RPM (revolutions per minute).*k*is a constant based on the cutting tool.

**Example Solve**

Let’s consider an example:

*Ra*=0.5 micrometers*A*=0.16*f*=0.002 inches*n*=1000 RPM*k*=0.35

By plugging in the values and calculating, you’ll get the surface finish.

**FAQs**
