1. What is Feed Rate Calculation?

Feed Rate Calculation determines the linear velocity at which a cutting tool moves through the material during machining operations. It's a critical parameter in CNC machining and manufacturing processes.

2. How Does the Calculator Work?

The calculator uses the Feed Rate formula:

Where:

• \( RPM \) — Rotations per minute of the cutting tool
• \( mm Per Rev \) — Millimeters of material removed per revolution

Explanation: The formula calculates the linear feed rate in millimeters per minute by multiplying the spindle speed (RPM) by the feed per revolution.

3. Importance of Feed Rate Calculation

Details: Proper feed rate calculation ensures optimal machining performance, extends tool life, improves surface finish quality, and prevents tool breakage or workpiece damage.

4. Using the Calculator

Tips: Enter RPM (rotations per minute) and mm per revolution values. Both values must be positive numbers for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: What units does this calculator use?
A: This calculator uses millimeters per minute (mm/min) for feed rate output, with RPM in revolutions per minute and feed per revolution in millimeters.

Q2: How does feed rate affect machining?
A: Higher feed rates increase material removal rates but may reduce tool life and surface quality. Lower feed rates provide better finish but slower production.

Q3: What factors influence feed per revolution?
A: Feed per revolution depends on tool type, material being cut, desired surface finish, and machine capabilities.

Q4: Can this calculator be used for different materials?
A: Yes, but optimal feed rates vary significantly between materials (aluminum vs. steel vs. plastics) and require adjustment based on material properties.

Q5: How accurate is this calculation?
A: The calculation provides theoretical values. Actual machining conditions may require adjustments for tool deflection, machine rigidity, and cutting forces.
