In this video tutorial, PROLIM PLM application engineer, Kyle Bentley, covers a brief introduction to NX CMM inspection programming.
Inside the template, there’s the “Machine View” and the “Method View.” The Machine View offers a tool rack with separate probes, while the Method View allows you to specify best practices for inspecting features.
Now, Kyle has some things already saved for new templates, including “Part Alignment features,” such “Teach Point” and the “Teach Point Path” to align the part coordinate system. If you don’t have those features, it’s easy enough to use the “Part Alignment Assistant” to help align the part coordinate system.
After aligning and positioning the part, we’re ready to run the feature “Link to PMI,” since PMI is already authored on the part. This will specify the inspection paths, features and tolerances with just a couple of clicks. Once PMI is successfully linked, you can run the program. You’ll see the features, such as cylinders and planes, be automatically created from the associated PMI.
Below “Features” in the “Program Order” window, you’ll see the created “Inspection Paths” based on the methods and features.
Before simulating, you’ll want to look at “Collision Avoidance.” All you have to do is select your program, then select “Collision Avoidance” in the toolbar. You can specify a safe plane, which Kyle specifies as 50 millimeters above the top of his part. This will optimize your inspection paths.
Now, you can select your program again and select “Simulation” in the toolbar. With no collisions, you can run through the simulation to verify inspection paths then postprocess to a standard DMIS, machine-specific or to a certain software. This will create your post directly from NX CMM.
