Frigate uses real-time acoustic sensing and multi-step finishing with variable-helix cutters to maintain compressive stress. Validation by Barkhausen noise and X-ray diffraction ensures fatigue resistance in load-bearing railway components.
Precision in Long-Part Machining
Dual-spindle synchronization, thermally compensated fixtures, and slideway feedback maintain sub-10 micron accuracy over long parts. Volumetric error mapping and laser tracker verification ensure straightness and squareness in structural rail components.
Multi-Axis Machining of Preforms
Five-axis probing and scanned mesh overlays adapt tool paths for asymmetric cast and welded parts. Machine learning reduces chatter, while gantry mills handle heavy preforms with precise lift compensation and tight tolerances.
- Step-by-Step Machining Approach
Our CNC Machining Process
Adaptive toolpath control combined with real-time sensor feedback and thermal compensation ensures consistent dimensional accuracy and subsurface integrity across complex railway components.
Advanced algorithms optimize tool paths, minimizing tool wear, reducing cycle times, and improving surface finishes. This involves strategically planning the sequence of movements and cuts to enhance efficiency.
Modern CNC machines often utilize 5-axis or even 6-axis capabilities, allowing for complex geometries and intricate shapes. This reduces the need to reposition the part, ensuring higher accuracy and a more refined finish.
CNC machines may integrate adaptive cutting strategies, where cutting conditions (speed, feed, depth of cut) adjust dynamically based on real-time sensor feedback or cutting force monitoring. This helps prevent tool breakage and ensures optimal material removal rates.
Specialized techniques like high-speed machining enable faster spindle speeds and advanced feed rates. This increases material removal rates while maintaining fine tolerances and reducing thermal distortion.
Some CNC setups incorporate in-process measuring systems (like laser scanners or probe-based systems) to check the part’s dimensions as it’s being machined. These systems can send real-time data back to the machine, allowing for automatic adjustments during production.
CNC machines with automated tool changers enhance efficiency by switching tools automatically without operator intervention. This allows for uninterrupted multi-operation machining without downtime, improving productivity in complex jobs with several cutting tools.

Frigate employs active thermal compensation algorithms in its CNC controls to adjust for heat buildup during extended runs. Machine enclosures maintain stable ambient temperatures within ±1 °C of the setpoint. Real‐time temperature probes on critical axes feed data into the control system for live parameter tuning. This prevents dimensional drift and machining errors over long production cycles.
After rough and finish machining, Frigate uses on‐machine probing systems to capture 3D surface coordinates. These measurements are compared against CAD datums to within ±0.01 mm accuracy. Any deviation triggers an automatic revision of tool offsets and toolpath adjustments. Final verification is performed with portable CMMs before shipment.
Frigate selects advanced carbide and PCD tooling tailored for AAR M‐70 grade steels, maximizing wear resistance. Adaptive feed‐rate control slows cutting when tool wear thresholds are detected by spindle‐load monitoring. A scheduled tool‐change strategy ensures blades are replaced before performance degrades. This approach extends tool life by up to 30% compared to fixed‐parameter machining.
Frigate’s process planning software nests finish allowances into the CNC program based on chosen coating or hardening treatments. Post‐machining parts are tracked via RFID through cleaning, plating, or induction‐hardening stages. Treatment‐induced growth estimates feed back into revised machining allowances for future batches. This closed‐loop system guarantees final dimensions within specified tolerance windows.
Frigate’s machines employ low‐frequency damped spindle assemblies to attenuate process‐induced vibrations. Prior to actual cutting, a test cut and vibration scan characterize the natural frequencies of each workpiece setup. CNC parameters are then dynamically adjusted to avoid resonance during heavy material removal. Continuous vibration monitoring ensures the process remains within safe limits, preserving surface integrity.
