Starrett vision system offers versatility for high-volume inspection
The new 3-axis vision system allows is well suited for both repetitive, larger part-run applications and routine quality assurance.
The L.S. Starrett Co. (Athol, MA, US), global manufacturer of measuring tools, gages and metrology systems, has introduced its AV450 Automatic Vision System. The new 3-axis vision system is designed for high-volume, repetitive applications and routine quality assurance. The AV450 has a 18-by-14-by-8-inch (457 by 356 by 203 mm) measurement envelope, high-resolution video zoom optics and can be pre-programmed (CNC) for repetitive part inspection, or driven manually via a trackball for individual measurements. Either QC5000 or MetLogix M3 software controls video edge detection and multiple-channel fiber optic or LED illumination. Computer-controlled Quadrant (LED) ring lighting, sub-stage lighting and optional through-the-lens lighting provides illumination.
The reported accuracy of the system is 2.5 + 5L/1000; reading resolution is 4 µin (0.1µm). Magnification on a 24-inch monitor at 1:1 pixel setting is 37x-240x with 6.5:1 zoom, and 25x-300x with 12:1 zoom. The system has a 1.3-megapixel color digital video camera and a granite base. The AV450 has an external motion control unit and includes a Windows-based operating system with an operator interface via a desktop PC with a 24-inch touchscreen monitor, as well as wireless network connectivity. CAD files can be imported and exported and reports can be generated and archived. M3 metrology software supports 3-axis measurements and 2D geometric constructs (such as points, lines, angles, rectangles and slots) and corrections for level, skew and datum origin. Options for the AV450 include a Renishaw touch-probe kit; an Optimet laser probe; 0.5x, 1.5x and 2.0x auxiliary lenses; an LED dark-field quadrant illuminator; and a DXF/field-of-view option for automatic comparison to CAD files. Other options include a CNC rotary axis fixture, touch probe change rack, calibration standards, part fixtures and workholding devices.
