9. Recommended Cutting Conditions
Parameters below are starting recommendations. Adjust based on machine rigidity, workpiece condition, and desired surface finish.
| Workpiece Material | Cutting Speed (Vc) | Feed Rate (f) | Depth of Cut (ap) |
|---|---|---|---|
| Mild Steel (C<0.3%) | 220–280 m/min | 0.15–0.40 mm/rev | 1.0–4.0 mm |
| Carbon Steel (C>0.3%) | 180–250 m/min | 0.12–0.35 mm/rev | 1.0–3.5 mm |
| Alloy Steel | 150–220 m/min | 0.10–0.30 mm/rev | 0.8–3.0 mm |
| Tool Steel (Annealed) | 120–180 m/min | 0.10–0.25 mm/rev | 0.5–2.5 mm |
| Stainless Steel (Austenitic) | 100–150 m/min | 0.12–0.25 mm/rev | 0.5–2.0 mm |
10. Operating Guidelines
- Coolant: High-pressure coolant (70–100 bar) recommended for chip evacuation and temperature control. Use water-soluble coolant with 8–10% concentration.
- Entry Angle: Maintain 91–95° tool entry angle for optimal chip control and minimal notch wear.
- Edge Preparation: Standard T-land (0.05 mm × 20°) suitable for most steel applications. For interrupted cuts, consider honed edge (0.08 mm radius).
- Speed Adjustment: Reduce cutting speed by 15–20% for interrupted cuts or scale/rusty surfaces. Increase by 10% for continuous cuts with stable setup.
- Feed Rate: Minimum feed should not fall below 0.10 mm/rev to ensure proper chip formation and avoid built-up edge.
- Depth of Cut: Avoid depths below 0.3 mm when using chipbreaker inserts to prevent rubbing and premature wear.
- Tool Overhang: Minimize tool overhang to 1.5× insert size for maximum rigidity and vibration damping.
11. Toolholder Compatibility
The SNMG150612PH is compatible with standard ISO toolholders designed for square (80°) inserts with 0° (negative) clearance. Recommended holder styles:
- Standard Holders: MCLNR/L, MCKNR/L (90° toolholders), MCLNN (75° toolholders)
- Insert Clamp: Lever lock or top clamp system with carbide shim
- Shim Requirement: Use carbide shim matching insert size (e.g., 15.875 mm IC shim) for protection and height consistency
- Shim Seat Angle: Must match insert clearance angle (0°)
- Holder Material: Alloy steel (42CrMo4) with hardened pocket (50–55 HRC)
- Compatibility Check: Verify holder pocket size (IC 15.875 mm) and clamp type match insert hole pattern
