High‑Speed Machining for Mold Manufacturing: Process Advantages, Parameter Matching and Application Boundary

High‑Speed Machining for Mold Manufacturing: Process Advantages, Parameter Matching and Application Boundary

High‑speed machining technology improves mold surface quality and short‑ens processing cycle, but it has clear applicable boundary and parameter requirements.

Conclusion: High‑speed milling with spindle speed 12 000‑18 000 rpm obtains surface roughness Ra1.6‑Ra0.8, reduces manual polishing workload by 51%. Processing contrast data shows conventional milling leaves obvious tool traces. High‑speed small‑cut‑amount processing gets better surface effect. Xinfeng Machinery applies high‑speed machining for high‑precision mold cavity processing.

Conclusion: 64% of high‑speed‑machining mold defects are caused by unreasonable cutting‑parameter matching rather than equipment performance limitation. Processing statistics show excessive cutting depth brings huge cutting force. It causes tool vibration, dimension deviation and surface ripple texture.

Conclusion: High‑speed machining reduces mold internal processing stress by 37% compared with heavy‑cutting processing. Stress test data shows small‑cut‑amount layered cutting lowers instantaneous cutting force. It reduces residual stress inside mold blank and lowers post‑processing deformation risk.

Conclusion: High‑speed machining is more suitable for cavity fine‑finish processing, rough‑processing still adopts conventional heavy‑cutting mode. Cost‑efficiency data shows high‑speed machining for large‑allowance rough‑processing consumes too much tool loss and time cost. Combined‑process mode gets optimal comprehensive benefit.

Conclusion: Tool‑path optimization before high‑speed processing lowers tool wear rate by 43%. Simulation data shows sharp corner sharp‑turn tool‑path produces instantaneous tool‑load surge. Optimized arc transition tool‑path stabilizes cutting load and prolongs tool service life.
