Creaform Inc. helps companies seamlessly create, simulate, verify, and collaborate in 3-D, significantly enhancing their turnaround times and profitability. In addition to designing and selling its 3-D laser scanners/systems, 3-D digitizers, portable CMMs, dual camera sensors, and distributing other 3-D measurement systems and software, Creaform offers design and engineering services, reverse engineering, finite element analysis, 3-D and long-range scanning, inspection, training, and staff outsourcing.

Leader in portable 3D measurement solutions and 3D Engineering Services, announces the installation of probing optical technology and noncontact 3D measurement systems at the BMW plant in Munich, Germany. The TRUaccuracy technology, which is integrated in all Creaform systems, was a key factor in the decision.

Since October 2012, several Creaform 3D measurement tools have been in use throughout the BMW plant, including the MetraSCAN 3D optical CMM 3D scanner, the HandyPROBE arm-free coordinate measuring machine, and the EXAscan portable self-positioning 3D scanner from the Handyscan 3D product line. Also, the BMW Rosslyn plant in Pretoria, South Africa, has been using the HandyPROBE portable coordinate measurement system since 2011.

  • It is fast: Automated inspection and quality control of up to a few hundred parts per day, directly on the production line. 
  • It is versatile: The solution can be fully configured and programmed (inspection programs) to meet inspection automation projects requirements for parts of various sizes and shapes. 
  • It permits highly-accurate measurements: Accuracy of up to 0.085 mm in real-life, shop floor conditions (no matter instability, vibrations, thermal variation, etc.). Accuracy of dimensional measurements is determined by the optical CMM scanner and is independent from the robot. 
  • Automatic alignment available: Instant and reliable alignment phase. Optical reflectors allow automatic detection of the part alignment. 
  • Dynamic referencing available: With the C-Track’s dynamic referencing mode, the coordinate system can be literally “locked” onto the part being measured, thus maintaining part alignment during the entire scanning process. 
  • Self-calibration available: fast calibration process using a certified gauge, which ensures constant accuracy during the MetraSCAN-R entire life cycle. 
  • It permits continuous monitoring of parameters: Monitoring of parameters such as temperature and accuracy ensure constant device accuracy during entire useful life. 

  • On-line inspection in mass production, up to a few hundreds parts/day 
  • On-line inspection of parts ranging from 0.5 to 3 meters in size 
  • Part-to-CAD analysis 
  • Supplier product quality inspection 
  • Conformity assessment of 3D models against original parts or production tooling 
  • Conformity assessment of manufactured parts against originals 

VXelements Data Acquisition Software:
The MetraSCAN-R robot-mounted optical CMM scanners are powered by Creaform’s VXelements data acquisition software, interfaced with Metrologic’s X4 i-Robot.Thanks to VXelements, the Creaform MetraSCAN-R 3D scanners generate a surface quality that compares very favourably with other high end scanning devices on the market. Because they combine Creaform’s 3D scanning capabilities with the robot-driving and inspection capabilities of Metrologic’s i-Robot software solution, the MetraSCAN-R series represents a high end automated scanning solution with diverse applications:
  • Surface optimization algorithm. 
  • Optimized meshing output. 
  • No limitation to the scan resolution: it can be changed at any time before or after the scan. 
  • Recreation of a meshing from raw data previously acquired. 
  • Real-time surface rendering. 
  • Optimization of the meshing such as hole filling, smart decimation (without definition loss on the meshing), or boundary filters. 

Creaform probing and noncontact 3D measurement systems were chosen not only for their flexibility, measurement speed, accuracy, and ease of use, but for the possibility to integrate seamlessly to existing structures. The systems are used for the evaluation of supplier parts, body circumferences, and entire vehicles.

Thanks to the TRUaccuracy technology, which features dynamic referencing, automatic drift detection and alignment, measurements can be taken directly on a vehicle, without having to jack it up and secure it. Vibrations from an unstable measurement system setup do not affect the accuracy.
