APPLICATION VERSATILITY New technology exists in the form of a large field-of-view benchtop vision measurement solution that is capable of being used in either a vertical or horizontal orientation, features a high-resolution digital video camera and precision optics for accurate, large FOV measurements. The latest system lends itself to an extremely wide array of applications from flat parts to turned, threaded and complex shaped parts such as orthopedic joint implants. A main operator interface displays a live video image with touch-screen enabled software measurement tools and graphical digital display of measurements. A part image can be resized using pan and pinch zoom. Measurements can be taken by simply touching a feature on the monitor screen. A wireless keyboard and pointing device can be used to enter file names and target key functions. Software includes 2D geometric functions such as points, lines, circles, arcs, rectangles, distances, slots, angles and skew, and utilizing the part design DXF/ CAD file digital overlay makes part inspection simple.
New, innovative HVR100-FLIP large field-of-vision (FOV) Bench-top Vision Measurement System is capable of being used in either a vertical or horizontal orientation, features a high- resolution digital video camera and minimal optical distortion for accurate FOV measurements of up to 90mm (3.65").
SELECTION TIPS For the best outcome, it is prudent to consult with an expert in this field. In addition, the following tips and considerations aid the selection process. 1. Measurement complexity . A 2D optical comparator may suffice for simple measurements and visual comparison, but more complex medical parts may require a multi-sensor metrology systems with CMM style touch-probe capability. 2. Measurement throughput . A manual system may be an option for prototypes, occasional and short run measurements by the QC department, but an automatic, CNC system is a more economical solution if complete production runs are to be verified.
3. Tolerance requirements . A Vision metrology system with a granite base may be required for meeting right tolerances, crucial for manufacturing medical parts. Tight tolerance may also indicate the need for higher magnification optics. 4. Size and weight of parts . A benchtop optical comparator or video metrology system may be appropriate for small parts, while a larger, floor-standing system can be helpful for large and heavy parts. 5. Harshness of environment . Most optical comparators are designed for typical machining environments sometimes found in machine shops. Varying temperatures, vibration, dust and oil particles can be present and need to be taken into consideration. 6. Man-made interface . Various interface options are now available for both optical comparators and video- based measurement systems including digital readouts, touch-screen PC solutions and rack-mounted computers with monitors/ software. 7. Software features . Capabilities can range from a simple two-axis readout to 3D multi-sensor capability with a rich set of measurement software tools, CNC control, statistical packages, DXF CAD file import and export, touch-screen operation with Windows Operating Systems and network connectivity.
The QC of medical devices is critical to ensure compliance to federal regulations.
The HDV Horizontal Digital Video Comparators combine the best features of a horizontal optical comparator and a vision metrology system.
