As the manufacturing industry increases its focus on quality control, and parts become more diversified and complex automatic measurement programming is on the rise.

Such software uses 3-D CAD and product manufacturing information (PMI) to enable automated generation of measurement programs with one-click. A complex program that previously would have taken five hours to complete manually can now be completed in 15 minutes.

A MBD is a 3-D annotated model, and its data can sometimes be used instead of a traditional drawing. While manufacturers have used MBD for product definition for decades, they have only recently applied it as part of the quality assurance process, as it is efficient in getting CMM results for comparison to CAD models.

MBD enables embedded geometric dimensioning and tolerancing. The 3-D CAD model includes all relevant product information and high-level inspection planning data. MBD helps manufacturers streamline processes by simplifying workflows, speeding up programming, and reducing manufacturing costs due to saved time. 

Model-based definition also eliminates the need for a physical CMM to generate a program.

Manufacturers need only one CAD file to build and inspect a part. Then, all relevant details and notes are transferred into the inspection software, minimizing confusion. Design changes are automatically included, even on the most intricate parts.

This combats inconsistencies between the drawing and the CAD model, which boosts efficiencies.

Model-based definition also boosts traceability, makes it easy to change plan parameters and CMM configurations and improves productivity.
