Body assembly
Geometrical tolerances on assembled bodies always get tighter: new welding techniques create seam welds that are nearly invisible, at the same time customers are very sensitive to the appearance of gaps.

In-line inspection

In-line measurements have as clear advantage that every body on the assembly line is inspected. This however also requires a very flexible solution as multiple body variants are assembled on the same production line. At the same time there is the need to adapt the measurement program over time. In the short production cycle time only a subset of all possible body parameters can be measured.  This subset can change over time based upon the experience that is built-up. Finally some of the body features are hard to access.
 
Putting the K-Scan laser scanning solution on a robot offers some distinct advantages:

  • Robots are common tools in automotive assembly, renowned for their flexibility
  • K-Scan laser scanning provides absolute measurement data that can be compared directly to CAD data
  • Absolute measurements eliminate the need for a reference body in order to “calibrate” the set-up
  • Laser scanning provides more comprehensive information than the single values derived from point and shoot measurements
 
Next-to-the-line measurements
 
For detailed inspection, bodies can be taken from the assembly line at fixed time intervals and measured on a horizontal arm machine like the Metris LK HC90. This machine can be equipped with the “Dynamic Temperature Compensation” (DTEC) option to compensate for temperature variations which are common in a production environment. DTEC provides the highest precision in a temperature range from 10 to 35°C. The machine can be equipped with touch trigger probes and Metris LC/XC laser scanners for maximum operating flexibility.
