Automatic Vision System

The Starrett AVR Series, CNC Automatic Vision Metrology Systems are ideal for repetitive
measurements and automatic comparisons to CAD files. They are available with dedicated
6:5:1 or 12:s zoom Optics or a quick change bayonet lens mount which accepts the choice
of six interchangeable telecentric lenses for micron level resolution and optical distortion
down to 0.001% for accurate field-of-view measurements. The FOV can encompass an
entire small part up to 51 x 38mm, or a feature of a larger part and be seamlessly
integrated with stage motion to measure parts with up to 200mm AVR20) or 300mm (AVR300).
These systems are also touch probe compatible.

Operator Interface

The AVR Series is built around a 24”touch screen PC, which runs on MetLogix M3 CNC software under Windows 10 Professional. M3 Software supports 3-axis measurements and 2D geometrical constructs(Points, Lines, Angles, rectangles). The screen displays a live video image of the part, plus geometry tools and digital readings. The part image can be resized using pan and zoom and measurement can be taken by simply tapping a feature on the screen. With the M3 DXF/FOV option, CAD files can be imported over a Network and be automatically compared to the actual [part.
