Large scale metrology

One soft­ware fits all sizes

Highly accu­rate mea­sure­ments are more and more demanded in a large vari­ety of man­u­fac­tur­ing areas that have tra­di­tion­ally bypassed the qual­ity lab­o­ra­tory because they are quite sim­ply too big to fit.

When speak­ing of large vol­ume spec­i­mens, the most cur­rent exam­ples that come to mind are air­crafts, trains and ships. The safety of these means of trans­port depends on the qual­ity of the thou­sands of machined parts and assem­blies that make their struc­ture. They can be chal­leng­ing to con­trol directly on the shop floor because of their mag­ni­tude and complexity.

Some air­craft part inspec­tions, like wing spars, require a CMM that can mea­sure large dimen­sional com­plex geome­tries. The ribs of an aircraft’s wings and cen­ter wing box require a mea­sure­ment sys­tem that can smartly accom­mo­date their large pro­por­tions. Sub-​assemblies like air­frames or air­craft sec­tions require a flex­i­ble and highly accu­rate mea­sure­ment sys­tem that can be installed close to the pro­duc­tion line to improve the man­u­fac­tur­ing cycle time.

Whatever the mea­sur­ing equip­ment, all these com­plex parts are all sub­ject to high load, stresses, harsh envi­ron­men­tal con­di­tions and no com­pro­mise on qual­ity is accepted. That is why, at Metrologic Group, we have been work­ing for decades on the most reli­able 3D inspec­tion soft­ware.  A highly accu­rate dimen­sional mea­sure­ment for over­size work­pieces in all kinds of work­ing con­di­tions. We don’t just claim it. We do it!

Dive into a whole new level of per­for­mance and pre­ci­sion with Metrolog X4. The perfect-​match for the most ambi­tious and heavy-​duty projects

Most cur­rent chal­lenges in large scale Metrology
  • Oversize parts within the largest mea­sur­ing range
  • Large mea­sure­ment vol­umes with tight tolerances
  • Challenging inci­dent angles
  • Complex geome­tries
  • Harshest of con­di­tions on the fac­tory floor
  • Difficult-​to-​reach or inac­ces­si­ble fea­tures inside and outside

Only a com­pre­hen­sive soft­ware solu­tion like Metrolog can help address these short­com­ings and make your mea­sur­ing equip­ment per­form better.

Metrolog X4 for large scale qual­ity control

Experience first-​hand the poten­tial of highly pre­cise qual­ity con­trol for large vol­umes with Metrolog X4.

  • Fully com­pat­i­ble with all avail­able 3D mea­sur­ing equip­ment for large scale inspec­tion. Interfaces with all brands, all mod­els (large-​size CMMs, laser track­ers, laser radars & mobile opti­cal systems)
  • All com­mon CAD exchange and native for­mats are sup­ported, includ­ing CATIA
  • Extraordinary ease of oper­a­tion and max­i­mum per­for­mance granted by years of pro­gram­ming expe­ri­ence with 64-​bit oper­at­ing sys­tems. Metrolog X4 soft­ware archi­tec­ture uses all avail­able mem­ory and opti­miza­tion, always push­ing the enve­lope to achieve the best data quality.
  • Not only does the archi­tec­ture enable ease of use, but also the import and pro­cess­ing of large CAD files and heavy point clouds. High vol­ume 3D point cloud data is processed with­out decimation. 
  • The multi-​connection mode pro­vides the abil­ity to net­work instru­ments together to get the best accu­racy, bundling sev­eral instru­ment locations.
  • Measurement uncer­tainty cal­cu­la­tion due to instru­ments, tem­per­a­ture variations…
  • Tracking and man­age­ment of raw data
  • Flush and gap inspection
  • Remote con­trol allows real-​time mea­sure­ment data visu­al­iza­tion where it is needed and remote con­trol of mea­sur­ing instru­ments from any portable device free of charge (smart­phone, tablet, PC…).
