1. What is Slitting Saw Speed and Feed?

Slitting saw speed and feed calculations determine the optimal rotational speed (RPM) and feed rate for milling operations using slitting saws. Proper calculations ensure efficient material removal while extending tool life.

2. How Does the Calculator Work?

The calculator uses these fundamental formulas:

Where:

• \( RPM \) — Revolutions per minute
• \( SFM \) — Surface feet per minute
• \( D \) — Tool diameter in inches
• \( Feed \) — Feed rate in inches per minute
• \( \text{chip load} \) — Chip load per tooth in inches per revolution

Explanation: The formulas convert surface speed to rotational speed, then calculate feed rate based on desired chip load.

3. Importance of Proper Speed and Feed

Details: Correct speed and feed settings prevent tool breakage, reduce heat buildup, improve surface finish, and maximize material removal rates.

4. Using the Calculator

Tips: Enter SFM based on material being cut, tool diameter, and recommended chip load for your tool and material combination. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What SFM should I use for different materials?
A: Typical SFM ranges: Aluminum 500-1000, Steel 100-300, Stainless 50-150, Plastics 300-800. Consult tool manufacturer recommendations.

Q2: How do I determine chip load?
A: Chip load depends on tool material, workpiece material, and cutting conditions. Start with manufacturer recommendations (typically 0.001-0.010 in/rev for small saws).

Q3: What happens if RPM is too high?
A: Excessive RPM causes heat buildup, premature tool wear, poor surface finish, and potential tool failure.

Q4: What if feed rate is too low?
A: Too low feed causes rubbing instead of cutting, increasing heat and reducing tool life without improving finish.

Q5: Should I adjust for coolant?
A: With coolant, you can typically increase SFM by 10-20%. Always monitor tool performance when adjusting parameters.
