Threading RPM (Revolutions Per Minute) refers to the speed at which a tool or machine, typically a lathe or milling machine, rotates when cutting threads into a material. The RPM is a crucial factor in threading as it impacts the quality of the threads and the tool’s lifespan. It is determined based on the type of material being threaded, the type of tool being used, and the desired thread size and quality.
The formula to calculate threading RPM is:
\[ \text{RPM} = \frac{\text{CS} \times 12}{\text{TPI}} \]
Where:
Let's assume the following values:
Using the formula:
\[ \text{RPM} = \frac{100 \times 12}{10} = 120 \text{ RPM} \]
The threading RPM is 120 RPM.
