Delcam PowerInspect 2012 eases inspection tasks

A mirror command that saves programming time for symmetrical components allows the inspection sequence to be mirrored from one half of a component to the other half, or from the left-hand version of a design to the right-hand copy. It can also reduce the possibility of programming errors and improve the consistency of the results between the two halves or between a pair of parts, says Delcam. The range of dimensions that can be displayed on the model has been increased to include more types of distance, angle, and diameters and radii. The options to display the various dimensions from the increased range have been made more versatile, to ensure the reports remain easy to read with only the required dimensions shown in the report. There are two additions to the PowerInspect 2012 point-cloud module for laser scanners and other point cloud devices. STL export provides basic reverse engineering functionality for scanned data. The STL files can be used within Delcam's PowerShape Pro design software for more advanced reverse engineering operations. In addition, point-cloud display has been enhanced with an option to show any back-facing points in a second colour. This highlights any discontinuities in the data, including gaps or other problem areas, and so makes it easier to identify areas that may need re-scanning to capture the complete model. Another enhancement in Delcam's PowerInspect 2012 makes it possible to measure edge points directly: it is no longer necessary to measure the surface first. This makes the process both easier and faster. But it is recommended that both the edge and the surface should be checked if there is any likelihood of the part being distorted, for example, when checking flexible sheet metal or composite components. Delcam has improved the inspection of castings and forgings, and similar near-net shapes, with the addition of a best-fit option. This centres the component within the measurement data so that the largest possible minimum stock is located on the part. It helps to ensure that positive material exists in all areas of any semi-finished part before it is sent for further machining. The approach can be used with the PartAligner option to minimise machining set-up times. A number of enhancements have been included to give faster and easier programming, with less chance of errors. A new 'lock workplane' option automatically creates a datum scheme matching the part's co-ordinate system within Delcam PowerInspect's GD&T True Position, while standard tolerances for Limit and Fit to ISO 286 and ISO 2768 have been included so that they can be selected from a pre-defined list.
