Realize LIVE: Streamline your CAM and CMM Processes Using PMI

By Stephanie Aldrete

Join us on Wednesday, June 24, 12:30 PM – 12:50 PM EDT / 9:30 AM – 9:50 AM PDT

The successful launch of an automated CNC machining line involves a large team working concurrently. Competitive pressures require a lean manufacturing planning process so that time is not wasted by manual re-entry of data at every stage.

The PTME team at Ford is implementing a MBD Strategy in the design of high volume machining lines for automotive powertrain components. The emergence of PMI as an industry standard means that the manufacturing and inspection engineering workflow can be streamlined for higher efficiency and lower cost. This presentation will highlight the benefits of this strategy including higher quality information and the ability to automate repetitive engineering tasks through the reuse of PMI information.

Part 1 of this session will show how PMI information is used to make faster and more consistent CAM decisions.

•Creation of optimized toolpaths using the Machining Knowledge Editor that reflects information embedded in the 3D model. 
•Generation of 3D in-process models that represent the as-cut condition using the capabilities of NX MLP to validate the entire line.
•Customization using the NX Open API to fill in the gaps so that in-process PMI tolerances can be created using mathematical stack-ups.
Part 2 of this session will show how the same PMI information is reused to create CMM programs integrated on the machining line.

•Significant reduction of CMM programming time over interactive input of tolerances.
•Programming of In-process inspection on shop hardened CMMs or On-Machine Probing using the In-Process PMI output from the individual operations.
•End of Line inspection using the finished part PMI.
