Recommended Cutting Conditions
Optimized parameters for CA4515 grade with SNMG120408C geometry. Start with conservative values and increase based on machine capability:
| Workpiece Material | Cutting Speed Vc (m/min) | Feed fn (mm/rev) | Depth of Cut ap (mm) |
|---|---|---|---|
| Carbon Steel (P) | 150-250 | 0.25-0.40 / 0.15-0.25 / 0.08-0.15 | 2.0-4.0 / 1.0-2.0 / 0.3-1.0 |
| Stainless Steel (M) | 100-180 | 0.25-0.40 / 0.15-0.25 / 0.08-0.15 | 2.0-4.0 / 1.0-2.0 / 0.3-1.0 |
| Cast Iron (K) | 120-200 | 0.25-0.40 / 0.15-0.25 / 0.08-0.15 | 2.0-4.0 / 1.0-2.0 / 0.3-1.0 |
*Values shown as: Roughing / Semi-Finishing / Finishing. Adjust based on machine rigidity and workpiece condition.
Operating Guidelines
- Tool Overhang: Minimize overhang to reduce vibration. Use shortest possible toolholder.
- Coolant: High-pressure coolant (70+ bar) recommended for chip evacuation. Use water-soluble coolant at 8-10% concentration.
- Entry Angle: Maintain 45-75° entering angle for optimal chip control and reduced notch wear.
- Edge Preparation: Do not re-sharpen or re-coat inserts. Use only new inserts from sealed packaging.
- Insert Change: Change insert when flank wear (VB) reaches 0.3mm or when surface finish degrades.
- Storage: Store in original packaging at room temperature. Avoid humidity >60% RH.
