Formulas:
- Roughing RPM = 6,000 / Diameter (inches)
- Finishing RPM = 9,000 / Diameter (inches)
- Rim Speed (FPM) = (π × Diameter × RPM) / 12
Setup Checklist
- [ ] Inspect workpiece for defects (cracks, knots, metal)
- [ ] Mark centers on both ends
- [ ] Mount drive center/chuck/faceplate
- [ ] Install live center in tailstock (if needed)
