While many tend to use Best Fit alignments for inspection, the truth is that the alignment method may not provide the most accurate inspection results. When using a Best Fit alignment process, you are relying on the inspection software to understand the design intent and align the scan of the manufactured part properly to the nominal CAD model. If datums aren’t provided to use for alignment by the inspection drawing or PMI model, you would [...]

In this blog post, we’ll take a look at a scanned part in Geomagic Wrap and show how we can correct its orientation to prepare it for CNC machining. Very often, when we scan parts their orientation is not necessarily known. It could be skewed off plane relative to the angle that the scanner was used when the scans were taken. By cycling through some various orthographic views, you may find that your scan is [...]
https://cimquesttv.wistia.com/medias/d8rs1ft8ak?embedType=async&videoFoam=true&videoWidth=640 Inspect a Scan Without CAD Model - Geomagic Control X Generally when we’re using Control X for inspection, we’re comparing one scan file to another scan file, or a scan file to a nominal cad file. But sometimes, we have the need to inspect or measure a one off part without a CAD file to compare it to.
While most inspection software will use a nominal CAD model during the inspection process for comparison of manufactured features to exact CAD features, Control X can perform a feature-by-feature analysis without utilizing a CAD model. This can come in very handy when a CAD model doesn’t exist for inspection and just a 2D drawing is used. The first step is to import just the mesh file or point cloud into Control X. As a reminder, [...]

This not only saves time by using the proper tool for the job, but also substantial outsourcing costs.

If we want to take this into Mastercam to generate toolpaths, we generally want to square it up.
Let’s take a look at how to interpret 3D and 2D color maps using inspection software. Non-contact inspection software that is designed to show color maps will align the scan of a manufactured part with a nominal CAD model and actual manufacturing tolerances are revealed in a clear, easy to interpret fashion. Some products can show a blended color map whereby a color (typically green) represents a nominal tolerance. For the connecting arm color map [...]
