Pilot plant
The goal of the pilot plant is to verify all assembly procedures in order to avoid any problems during series production. This requires a thorough dimensional control of every component, subassembly and finally the fully assembled vehicle against CAD data.

Detailed inspection to CAD

With the Metris LK Camio software CMM programs can be prepared off-line starting from the CAD data. This makes sure that inspection can start right after the first series prototypes are available, avoiding a time consuming teach-in process. Metris LK Camio supports the full range of  Metris LK CMM including the LY90 layout machine.
Inspection of master buck

Virtual sheet metal assembly
 
In sheet metal assembly, the shape of the mating surfaces determine to a great extend how well the different parts will fit together. This can be done by physically putting them together on a “master buck”. A better alternative however is to assemble both parts virtually by scanning the mating surfaces and checking the fit in a package like Focus Inspection. For this the CMM can be equipped with a Metris line or cross-scanner or the K-Scan handheld solution can be used.
 
Closure inspection
 
For esthetical reasons, closures have to be fit symmetrically in the body opening. By moving a laser scanner, like the Metris K-Scan handheld scanner, along the circumference of the closure a detailed gap & flush analysis can be done.
 
A less obvious, but equally important analysis is the compression of the seals between body and closure: in case the seal is compressed too much, it will take more effort for the customer to close the door, while he will probably complain about wind noise if the seal isn’t compressed enough. The seal compression can’t be measured directly as it isn’t accessible as soon as the door is closed. The K-Series portable CMM and K-Scan laser scanning system here offers an alternative solution.
