Titanium Machining Calculator

Calculate optimal CNC machining parameters for titanium alloys: Ti-6Al-4V Grade 5 (aerospace), Ti-6Al-4V ELI (medical), CP Ti Grade 2/4, Ti-6Al-2Sn-4Zr-2Mo with critical safety warnings for South African aerospace and medical manufacturing.

CRITICAL SAFETY: High-pressure coolant REQUIRED - titanium fire risk if machined dry

Extremely low thermal conductivity - heat stays in cutting zone

🔥 TITANIUM MACHINING SAFETY - CRITICAL

• NEVER machine titanium dry - fire and explosion risk (chips ignite at 600°C)
• High-pressure coolant (70+ bar) REQUIRED - minimum 20 liters/min flow
• Sharp tools essential - dull tools cause instant galling and heat buildup
• Constant feed critical - stopping while engaged causes work hardening
• Wet chip collection mandatory - keep chips submerged, remove frequently
