## Scope

United States and Europe. The custom-parts manufacturer's annual report says it uses AI in a number of ways, including toolpath verification in CNC machining and automated quality inspection in injection moulding, and that its proprietary software and business process automate the non-recurring manufacturing engineering in many of its services; it says it has used automated digital manufacturing since 1999 to reduce labour dependency. The company's own description of its own plants; it gives no count of programmers or hours, and 'many of our services' mixes machining with moulding and 3D printing.

## What this means

A manufacturer running its own CNC plants checks machine programs with AI and automates much of the per-part engineering.

## What it does not show yet

The company's own description, with no figures on programmers' work, and machining mixed with other processes.

## How to verify it yourself
