Exact Metrology (Brookfield, WI and Cincinnati, OH) has added multi-piece editing as a function of its PolyWorks Inspector. Users can now make changes in one piece that can be propagated to other pieces.
Users with multiple pieces can make changes like creating, editing features, alignments, and reporting items. These changes can then be transmitted to past and future pieces/templates and used to create custom propagations or the changes can be applied just to the current piece. After choosing the propagate option, the user sees the changes in the other pieces and/or templates including report(s) or report items.
Another update of PolyWorks Inspector is augmented GD&T. Center point features can now be reported with more capabilities including circularity, flatness and perpendicularity. Users can also see MIN/MAX deviations and can view the color arrow deviation tags.
An online tutorial shows how to make sure the Hexagon Romer Absolute Arm is still in calibration. First, the bar artifact needs to be placed correctly to scan it. The ideal location is centered with the main axis of the arm at a distance away where it will be just below the elbow when the arm is extended out. To secure the bar, use pre-drilled tapped holes. They accept simple machinist fixturing to hold it in place. C-clamps can also be used to secure the bar to a rigid table. When doing a length checkout, only the 15 mm master probe should be used. Next, the user needs to open RDS Data Collector.
Used with Hexagon Romer Absolute Arm, the software allows the operator to check the accuracy of the arm and probes and calibrate/align the probes and scanner as necessary. To start probing, move the probe to the first position. The probe needs to be properly seated in the conical feature at each end of the bar. Following the prompts in RDS, move the probe to the end conical features and pull the trigger to record a point. Once 10 positions have been recorded, RDS will display the results. The MIN/MAX values should be below the standard values for the type of arm being used.
