Feed Per Tooth Calculator

The Feed Per Tooth Calculator is a crucial tool in machining and manufacturing. It helps determine the feed rate per individual tooth of a cutting tool, which is vital for optimizing the machining process and ensuring tool longevity. This calculation is particularly important in milling operations, where precision and efficiency are key.

Historical Background

Machining has evolved from manual processes to highly sophisticated computer-controlled operations. Understanding the feed per tooth allows machinists to fine-tune their operations to achieve the best surface finish and avoid excessive tool wear.

Calculation Formula

The formula to calculate feed per tooth is as follows:

\[ \text{Feed Per Tooth} = \frac{\text{Feed Rate (mm/min)}}{\text{Spindle Speed (RPM)} \times \text{Number of Teeth}} \]

Example Calculation

If your feed rate is 1000 mm/min, spindle speed is 500 RPM, and the tool has 4 teeth, the calculation would be:

\[ \text{Feed Per Tooth} = \frac{1000}{500 \times 4} = \frac{1000}{2000} = 0.5 \text{ mm/tooth} \]

Importance and Usage Scenarios

Calculating the feed per tooth is essential for selecting appropriate cutting conditions that improve tool life, enhance surface finish, and increase the efficiency of the machining process. It is particularly relevant in high-precision industries such as aerospace, automotive, and tool manufacturing.
