Controlled stock removal and stress relief cycles achieve flatness under 0.03 mm across 250 mm spans. Laser profilometry verifies thermal interface integrity under both ambient and elevated temperatures.
- Machining Workflows
Our CNC Milling Process
Tight component tolerances and fine feature depths are achieved through high-speed, thermally stable CNC milling in cleanroom-compatible workflows.
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 a unified toolpath strategy across both prototyping and volume production platforms. This ensures machining logic, tool approach vectors, and datum references remain identical across builds. Critical features maintain dimensional deviation within ±0.003 mm from EVT to DVT. As a result, connector stack-ups, thermal interface points, and mounting geometries require no re-baselining during validation.
Frigate integrates EMI shielding features—such as knife-edge joints, interference-fit flanges, and internal baffle geometries—directly into the milling process. These features are machined to sub-50 µm precision without relying on gaskets or secondary parts. Shielding effectiveness is validated using near-field RF scans and structural integrity under vibration. This approach delivers over 80 dB attenuation across telecom frequency ranges, even in harsh environments.
Frigate uses pre-machining stress relief cycles and controlled material removal strategies to prevent baseplate distortion. Flatness across thermal interfaces is kept below 0.03 mm over spans up to 300 mm. Laser profilometry is used post-machining to validate planarity under thermal load conditions. This ensures consistent contact resistance and prevents thermal runaway in high-power telecom systems.
Connector mounts are machined using coordinate-based referencing with tolerance stacks managed through GD&T principles. Concentricity and angularity are maintained within ±0.005 mm to avoid mechanical stress on high-frequency RF and fiber connectors. Frigate performs positional validation using optical metrology and CMM routines. This reduces insertion force drift and extends connector life over multiple field cycles.
Frigate combines CMM-based dimensional inspection with DPD-linked digital traceability systems. Each part includes a full-featured inspection record aligned to its functional surfaces, mating features, and thermal zones. Critical-to-function dimensions are monitored via SPC to catch drift across production runs. These protocols ensure readiness for system-level certification without post-machining modification.
