Innovative PMI-Based Inspection Planning for Planar and Cylindrical Features

TLDR: PMI-based inspection planning, the CAD model affixed with PMI is fed to the inspection software, then most of the traditional inspection steps are automated by reading and extracting PMI from the CAD models, identifying the feature associated with a PMI and then developing an inspection strategy on the identified feature.

Abstract: Coordinate Measuring Machine is used to inspect the manufactured products to ensure that they meet the desired specifications. In most of the inspection software, including PMI, the inspection process involves loading of the CAD model, selecting an inspection feature, feeding the PMI into the inspection software, and selecting an appropriate inspection strategy depending on the type of feature. Inspection results are then compared with the nominal tolerance values. This process involves the application engineer’s input at multiple stages. The automatic inspection process is becoming an important requirement in industries, which adds value to the inspection software and eliminates human intervention. In PMI-based inspection planning, the CAD model affixed with PMI is fed to the inspection software, then most of the traditional inspection steps are automated by reading and extracting PMI from the CAD model, identifying the feature associated with a PMI and then developing an inspection strategy on the identified feature. Later, results are validated by feeding the inspection points in the inspection software.
