1. What is the Cutting Rate Formula?

The Cutting Rate formula calculates material removal rate in square inches per minute (in²/min) based on surface feet per minute (SFM) and a dimensionless feed factor. This LENOX proprietary calculation helps optimize sawing operations.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• SFM — Surface feet per minute (cutting speed)
• Feed Factor — Dimensionless value based on material and saw type

Explanation: The formula provides the area of material removed per minute, which is crucial for optimizing sawing efficiency and tool life.

3. Importance of Cutting Rate Calculation

Details: Proper cutting rate calculation ensures optimal saw performance, maximizes blade life, and maintains cutting quality while preventing excessive wear or breakage.

4. Using the Calculator

Tips: Enter SFM (cutting speed) in feet per minute and the appropriate feed factor for your material and saw type. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Where do I find the feed factor?
A: Feed factors are typically provided in LENOX technical documentation or can be obtained from their engineering team based on material and saw specifications.

Q2: What are typical SFM values?
A: SFM varies by material, ranging from 50-150 for steels to 300-1000 for non-ferrous metals. Always consult material-specific recommendations.

Q3: How does cutting rate affect blade life?
A: Higher cutting rates increase productivity but may reduce blade life if pushed beyond recommended parameters. Optimal balance is key.

Q4: Can this be used for all saw types?
A: The formula applies to band saws, circular saws, and other continuous cutting operations, but specific feed factors may vary.

Q5: How precise should these calculations be?
A: While the calculation provides theoretical values, actual conditions (coolant, material consistency, machine condition) may require adjustments.
