1. What is Feed per Tooth?

Feed per Tooth is defined as the amount of work piece entering the machining per tooth. It is a critical parameter in machining operations that determines the material removal rate and affects tool life and surface finish quality.

2. How Does the Calculator Work?

The calculator uses the Feed per Tooth formula:

\[ f = \frac{F_{cutter}}{z \times N} \]

Where:

\( f \) — Feed per Tooth (m)
\( F_{cutter} \) — Feed rate of the cutter (m)
\( z \) — Number of teeth on the cutter
\( N \) — Spindle Speed (rad/s)

Explanation: The formula calculates the amount of material each tooth removes per revolution by dividing the total feed rate by the product of the number of teeth and spindle speed.

3. Importance of Feed per Tooth Calculation

Details: Accurate Feed per Tooth calculation is crucial for optimizing machining processes, ensuring proper chip load, maximizing tool life, achieving desired surface finish, and preventing tool breakage or premature wear.

4. Using the Calculator

Tips: Enter feed in meters, number of teeth (must be at least 1), and spindle speed in rad/s. All values must be positive numbers for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: Why is Feed per Tooth important in machining?
A: Feed per Tooth determines the chip load on each cutting edge, which affects tool life, surface finish, cutting forces, and overall machining efficiency.

Q2: What are typical Feed per Tooth values?
A: Typical values range from 0.05-0.5 mm per tooth for most materials, but vary significantly based on material, tool type, and machining conditions.

Q3: How does Feed per Tooth affect tool life?
A: Too low feed per tooth can cause rubbing instead of cutting, leading to premature tool wear. Too high feed per tooth can cause tool breakage or excessive wear.

Q4: Can this calculator be used for different units?
A: The calculator uses meters for feed and rad/s for spindle speed. For other units, convert your values to these units before calculation.

Q5: What if I have multiple cutting tools?
A: The calculation applies to individual cutting tools. For multiple tools, calculate feed per tooth separately for each tool based on its specific parameters.
