Frigate uses advanced GD&T-based machining protocols, ensuring feature-to-feature relationships remain within stackable tolerance limits. Our process simulation models assess how deviations compound across assembled structures. Fixtures are calibrated to preserve datum consistency throughout multi-op turning. This guarantees zero cumulative error at critical interfaces like coupler arms or brake beam housings.
Frigate applies vibration-mode FEA inputs to define turning profiles that avoid stress risers. We tailor fillet radii, relief grooves, and transition zones during turning to dissipate dynamic loads efficiently. Post-turning treatments ensure microstructure integrity remains intact. This minimizes the risk of fatigue crack propagation during prolonged operational cycles.
We model thermal expansion behavior during the CAM stage and apply toolpath strategies that balance heat input. Material removal is distributed to prevent asymmetric heat zones. Coolant flow and spindle speeds are dynamically adjusted to avoid thermal buildup. This results in stable geometry for components used from Arctic to desert conditions.
Frigate integrates metrology feedback loops using CMM and inline probing into the machining cell itself. Inspection data drives adaptive toolpath correction mid-run, ensuring consistent dimensional control. Each component gets a traceable ID linked to its process data set. This allows full visibility across quality, production, and compliance checkpoints.
We use back-cutting techniques and real-time force monitoring to prevent deflection in thin-walled sections. Tool pressure is optimized to maintain form without compromising structural load paths. Machining is validated against modal analysis to avoid resonance-induced deformation. This ensures lightweight parts maintain functional stiffness and safety margins under service loads.
