Hexagon Metrology’s Cognitens WLS400M helps deliver high level quality for the new Honda Civic

With the Cognitens WLS400M, Honda in the UK now carries out a root cause analysis in one shift instead of several days. Measurements that used to take 1.5 hours are now taken in 15 minutes. For Honda of the UK Manufacturing Ltd, customer satisfaction is everything. Precision measurement is employed at every stage of the manufacturing process to ensure that everything from the engine to the fit and finish of the body is as good as it can be. During the development phase of the award winning new Honda Civic, the Complex Analysis Team for High Accuracy Body (CAT HAB) used the Cognitens system to help the maturation process of crucial parts such as door assemblies and tail gates.

These critical areas affect both the aesthetics and the functionality of the vehicle. If a boot doesn’t shut properly or the gap between the door and main body doesn’t look right – customers aren’t happy and neither is Honda. This quest for accuracy is combined with a strict production deadline that must be hit in order to meet business objectives. Therefore the measurement strategy in the development phase must combine high accuracy with speed and efficiency.

The need for speed (and accuracy)
The CAT HAB team sits as a quality function in the Weld Division but brings together people from Paint, Assembly Frame and Product Engineering to pool experience and focus on complex issues that cut across departments. By using the Cognitens White Light scanning system from Hexagon Metrology the team were able to focus on specific areas and speed up root cause analysis of any imperfections in the development phase. The objective being to optimise fit and finish before mass production starts – and for customers to receive cars that meet the quality standard they expect from Honda.

The process begins with receiving the drawings from Japan and defining some critical parameters – then the first trial builds of the car are critiqued on a company basis. Focus areas are identified and the Cognitens WLS400M is used to verify child parts of sub-assemblies (stage measurement) as well as critical areas such as tail gates. The CAT HAB team leaders scan parts using Cognitens at different stages of the build process. For example a tail gate can be scanned when it arrives from Weld and before and after Paint, Assembly Frame and other departments. The tail gate scans can then be overlaid on each other to show where any changes have occurred and whether they sit outside agreed parameters. The Cognitens WLS400 sensor works by projecting a random pattern on...
