Build in ADS
Model tube structures, import geometry, and prepare fabrication-aware parts in Arma Design Studio.
Automation for real fabrication
Move from tube design to finished parts.
ARMA builds practical CAD/CAM software and compact CNC tools for shops that need repeatable tube fabrication without industrial-scale complexity.
The ARMA workflow
Design it. Prepare it. Fabricate it.
Our tools connect the digital model to the work happening on the shop floor: tube frames, chassis, roll cages, bumpers, racks, and other welded structures.
Generate the workflow
Create notches, tabs, slots, bend marks, nesting layouts, and machine-ready output from the same project.
Make repeatable parts
Use compact CNC hardware and clear setup information to move from a design to real welded assemblies.
Featured products
Capability that fits the shop you have.
Start with the software, add CNC tube cutting, or automate bending when your workflow is ready for it.

Tools shaped by the work they need to do.
ARMA Automation grew out of the same chassis, vehicle, and fabrication projects behind ARMA Automotive. That means the workflow starts with practical questions: how do parts fit, how are they supported, and how can a small shop repeat the result?
