CuttingParams - Machining Parameter Reference

Purpose: Quick lookup and calculation of cutting parameters. Starting points that work, with adjustment guidance.

When to Activate

"What's the SFM for 316 stainless?"
"Feeds and speeds for 7075 aluminium"
"What RPM for a 12mm endmill in steel?"
"Recommended DOC for titanium roughing"
"Help me optimize my cutting parameters"

Core Formulas

Spindle Speed (RPM)

RPM = (SFM × 3.82) / Diameter (inches)
RPM = (Vc × 1000) / (π × Diameter mm)
RPM = (Vc × 318.3) / Diameter (mm)

Where:
- SFM = Surface Feet per Minute
- Vc = Cutting Speed in m/min

Feed Rate

Turning:

Feed (mm/min) = Feed per Rev (mm/rev) × RPM

Milling:

Feed (mm/min) = Feed per Tooth (mm/tooth) × Number of Teeth × RPM

Metal Removal Rate (MRR)

Turning:

MRR (cm³/min) = DOC × Feed × Vc × 1000

Milling:

MRR (cm³/min) = WOC × DOC × Feed Rate / 1000
