Advanced Programming for Coordinate-Measuring Machines
NX enables you to generate complete machine inspection programs for coordinate-measuring machines (CMM). NX CMM Inspection Programming reduces programming time, frees-up expensive CMM machine resources and ensures fast responses to design changes.
You can reduce inspection programming time by as much as 80 percent by using the product and manufacturing information (PMI) – including GD&T and 3D annotation – that is associated with the CAD model. NX CMM programming can use this data to generate inspection programs automatically. You can further automate the programming process by applying your own standard inspection path methods, tools and project templates.
By selecting the appropriate postprocessor, you can have the NX CMM software create machine instructions in DMIS or machine-specific formats. Before sending the program to the shop floor, you can make sure that inspection programs are collision free and match the intended measurement strategy. NX also provides inspection program verification and full machine simulation, including a number of standard CMM machine models. The kinematic model-based simulations of the machine allow you verify that all features are reachable, and that machine limits are not exceeded.
You can rapidly update inspection programs based on design and manufacturing changes by using the associativity between NX CAD, CAM and CMM applications. Siemens also offers CMM Inspection and Execution software to drive coordinate-measuring machines using the output from NX CMM.
Visualize: With NX CMM’s data analysis capabilities, you can quickly see and evaluate your “as-built” measurements in a graphical environment, right next to the “as-designed” models that drive your CMM inspection programs. Putting the measurement results into context helps you find the most effective approaches to achieve quality improvements.
Analyze: CMM measurements are read back into NX as .mea or .dml files. They are compared to the measured data, including the associated tolerances according to ANSI Y14.5, ASME Y14.5 or ISO 1011 standards. Measurements are displayed in the operation navigator as a list and linked to the graphical display for each measurement. Best-fit analysis and verification help you find the possible causes of tolerance failure and assist in decision-making that will improve component quality.
You can use Teamcenter for process and data management to ensure that you are always working with the correct file version regardless of your geographic location. The integration between Teamcenter and NX allows you to:
- Store the inspection part in Teamcenter as an NX model using NX interface.
- Attach the DMIS inspection file to the revision of the product item.
- View the 3D inspection model in Teamcenter as NX or JT data.
- Release the inspection model and the DMIS file for shop floor inspection.
