Design Creation

Engineers design the part using CAD (Computer-Aided Design) software. The design includes all dimensions and specifications.

Converting Design to CNC Code

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. 

Setting Up the Machine

Operators prepare the CNC milling machine by securing the material (workpiece) and installing the appropriate cutting tools. 

Running the Machine

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.

Monitoring and Adjusting

The machine monitors the cutting operations throughout the process. Operators may make adjustments to ensure precision and quality. 

Finishing Touches

After milling, the part may undergo additional processes like deburring or polishing to achieve the final specifications.

Quality Check

The finished part is thoroughly inspected to meet all design requirements and tolerances.

Having Doubts? Our FAQ

Check all our Frequently Asked Questions in CNC Milling

How does Frigate achieve repeatable tolerances in small-batch R&D prototype runs?

Frigate uses programmable digital offsets and toolpath mirroring to replicate part geometry across multiple runs. Custom fixturing blocks are indexed using master datum alignment to ensure zero shift during repositioning. Short-run quality loops validate critical dimensions after each cycle. High-resolution spindle encoders help maintain sub-0.01 mm tolerances even under low-volume conditions. This ensures consistent geometry in all prototypes produced across different iterations. 

What techniques does Frigate use to prevent thin-walled deformation during milling of early-stage prototypes?

Frigate employs low-pressure clamping systems and radial engagement control to reduce force transfer on unsupported features. Cutter entry angles are optimized using simulation to minimize lateral push. For extremely thin sections, intermediate roughing steps are applied before finish passes. Real-time force monitoring adjusts feed rates dynamically. These strategies protect thin-walled zones from deflection or collapse during testing preparation. 

How does Frigate support dimensional integrity in multi-step prototypes with mixed-feature complexity?

Frigate uses compound zeroing routines and intermediate probing checkpoints to maintain dimensional reference across all setup stages. Indexed rotary tables allow multi-plane milling without resetting the part. CAM-driven tolerancing ensures adaptive toolpath adjustments for intersecting features. Every geometry layer is inspected using high-magnification metrology tools. This approach ensures feature alignment and integrity across complex prototype builds. 

What method does Frigate apply to ensure accurate surface roughness for sensor enclosure prototypes?

Frigate selects finishing cutters with specific corner radii designed to meet RA and RZ standards relevant to enclosure interfaces. Step-over values are calibrated per material conductivity to reduce micro-vibration marks. In-cycle feedback from spindle load variations is used to detect tool deflection and make real-time corrections. Final surface quality is verified using non-contact profilometers. This guarantees the enclosure performs reliably in EMI-sensitive testing.

How does Frigate validate part geometry across revised CAD versions during iterative prototyping?

Frigate retains version-controlled CNC programs linked to specific drawing revisions. Each incoming CAD update undergoes deviation mapping against prior runs using 3D comparison software. Toolpaths are adjusted only where geometry has changed, ensuring continuity in shared features. Reference datums are revalidated using tactile probe systems. This methodology supports rapid design evolution without sacrificing prototype part consistency.
