Speeds and Feeds Calculator
Calculate optimal cutting speed and feed rate for machining operations
📖 Speeds and Feeds
Cutting speed (SFM) and feed rate determine material removal rate and tool life. Proper speeds and feeds ensure efficient machining while protecting the cutting tool.

💡 Tips & Information
- Cutting speed is measured in meters per minute (m/min) or SFM
- Formula: V = π × D × RPM / 1000 (for m/min)
- Feed rate = Feed per tooth × Number of teeth × RPM
- Optimal speeds depend on material, tool type, and operation
- Start with conservative values and adjust based on tool wear and surface finish
