- Process Overview
Our CNC Milling Workflow
Our process integrates multi-axis programming, toolpath simulation, and part stabilization protocols to maintain repeatable outcomes in thick-section and asymmetric parts.
Engineers design the part using CAD (Computer-Aided Design) software. The design includes all dimensions and specifications.
The CAD design is converted into CNC code, often using CAM (Computer-Aided Manufacturing) software. This code tells the milling machine how to move and cut the material.
Operators prepare the CNC milling machine by securing the material (workpiece) and installing the appropriate cutting tools.
The CNC machine reads the code and starts milling. The cutting tool rotates and moves along multiple axes to remove material from the workpiece and shape it into the desired part.
The machine monitors the cutting operations throughout the process. Operators may make adjustments to ensure precision and quality.
After milling, the part may undergo additional processes like deburring or polishing to achieve the final specifications.
The finished part is thoroughly inspected to meet all design requirements and tolerances.

Frigate uses dual-station fixturing and high-torque table locks to prevent material drift across extended lengths. Servo-driven clamps and vibration-isolating pads reduce deflection during milling of open-side frame members. A laser tracker validates linear consistency before and after toolpath execution. This ensures that multi-meter frames retain flatness and dimensional uniformity across every mounting face.
Frigate uses predictive thermal expansion modeling during the CAM phase to adjust toolpaths for thick metal substrates. High-flow coolant systems are combined with thermal-controlled tool holders to neutralize spindle heat migration. Milling operations are divided into balanced passes to reduce localized heat zones. Final geometry is confirmed using infrared scanning to detect any temperature-induced deformation.
Frigate applies low-radial-runout boring tools paired with in-cycle probing to achieve precise hole locations. Pre-machining surface flatness is validated before drilling to reduce axial misalignment. Hole diameters are finished with reaming cycles using HSK tool holders to stabilize spindle contact. The result is high-pressure compatibility across mating hydraulic interfaces.
Frigate controls feed per tooth through real-time feedback loops based on alloy-specific chip morphology. Indexable cutters with edge prep geometry are used for abrasive-resistant steels. High-pressure through-coolant channels reduce tool tip temperature during slotting. This maintains edge integrity and lowers tool failure risk, especially in parts like cutting edges and bushing plates.
Frigate uses sequential toolpath optimization with axial compensation to achieve uniform surface profiles. Each pass is adjusted for tool deflection using digital dial gauge feedback. A coordinate measuring machine (CMM) validates flatness post-machining across defined grid points. Surface finish is inspected using profilometers to meet low-Ra requirements in rotational load zones.
