Current obstacles

Programming is a skilled bottleneckEach new part requires a trained CAM programmer to write toolpaths and validate in simulation.
Setup dominates for small batchesFor aerospace work with many designs in small batches, fixturing and probing cost more than cutting.

Physics limits

Tool life limits cutting speedFaster spindle speeds cut faster, but tools wear quickly at high temperature with hard thermal limits.
Rigid tooling needs exact part placementPreprogrammed paths work only when parts arrive exactly where expected without human intervention.

How it works

3 parts

Programmed motion

G-code to servo commands

CAD file becomes G-code; the CNC fires servo motors thousands of times per second.

Accuracy

Repeating to micron precision

Joint encoders and thermal compensation yield variations of only microns across thousands of parts.

Multi-axis work

Five-axis in one setup

Five-axis machines tilt parts to reach complex shapes without multiple workstation moves.
