Inspection Technologies

Inspection Technologies

1. Application-specific software refers to programs written for certain types of parts

   • Gear checking
   • Thread checking
   • Cam checking
   • Automobile body checking

2. Coordinate measuring machines are most appropriate for applications possessing the following characteristics:

   • Many inspectors are currently performing repetitive manual inspection operations
   • The application involves post-process inspection.
   • Measurement of geometric features requires multiple contact points.
   • Complex part geometry.
   • A wide variety of parts must be inspected
   • Repeat orders are common.

3. Post-Inspection Software

   • Graphical data representation.
   • Statistical analysis.

4. the advantages of using CMMs over manual inspection methods

   • Reduced inspection cycle time
   • Flexibility.
   • Reduced operator errors
   • Greater inherent accuracy and precision
   • Avoidance of multiple setups.

5. Core programs normally include the following:

   • Probe calibration
   • Part coordinate system definition.
   • Geometric feature construction
   • Tolerance analysis

6. Nearly all CMMs have a mechanical structure that fits into one of the following six types,

   • Cantilever.
   • Moving bridge.
   • Fixed bridge
   • Horizontal arm
   • Gantry
   • Column

7. The principal contact inspection technologies are the following

   • Conventional measuring and gaging instruments
   • Coordinate measuring machines (CMMs) and related techniques to measure mechanical dimensions
   • Stylus-type surface texture measuring machines to measure surface characteristics such as roughness and waviness
   • Electrical contact probes for testing integrated circuits and printed circuit boards

8. The choice of a device for a given application should emphasize those criteria that are most important

   • Accuracy and Precision.
