Multi-Axis Geometric Accuracy
Complex profiles are machined on 5-axis trunnion setups with inverse kinematics, digital twin simulations , and in-cycle probing to maintain true position within 0.01 mm across compound geometries.
Micron-Level Bore Alignment
Hydraulic interfaces and bearing bores are interpolated with synchronized cycles, followed by CMM-guided correction and reaming, achieving H7/g6 fits and precise coaxiality within micron tolerances.
- Step-by-Step Machining Approach
Our CNC Machining Process
Each part is manufactured through a controlled sequence of toolpath simulation, in-cycle probing, and thermal compensation to ensure dimensional fidelity across material batches and machine platforms.
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 preconditions all welded structures through thermal stress relief before machining. We use vibration-damped fixturing and dynamic axis compensation to limit distortion during cutting. Machining sequences are planned to balance internal stress release. Final verification is done with 3D CMM to confirm dimensional integrity across datum surfaces.
We use tool offset management with RFID-tagged tools and in-cycle wear compensation. Each machine cell includes in-line gauging systems to verify diameter and concentricity after each part. Statistical data is logged to monitor Cpk values for critical dimensions. This ensures consistent output across thousands of components.
Frigate selects low-speed, high-torque parameters with coated carbide inserts to manage flank wear. High-pressure coolant systems are used to evacuate chips and reduce thermal buildup. Depth-of-cut is minimized during finish passes to avoid microcracking. All parameters are tested in pre-production trials and logged into tool libraries.
We use extended-reach tools with anti-vibration damping and program Z-axis step-downs with reduced side-load. CAM simulations verify collision clearance and chip evacuation in confined zones. Probing routines reset the local zero after roughing for accurate finishing. Frigate achieves slot flatness and parallelism within ±0.015 mm.
Hole locations are machined in a single setup to avoid compound error stack-up. We use probing before and after machining to validate fixture alignment and part orientation. Positional tolerances are held within 0.01 mm relative to functional datums. Results are captured in an inspection report linked to part ID for traceability.
