ArcelorMittal is the world’s leading steel and mining company, with a presence in 60 countries and an industrial footprint in 18 countries. They are the leading supplier of quality steel in the major global steel markets including automotive, construction, household appliances and packaging.
IKM Haaland AS, part of the IKM group, is one of Norway’s biggest sheet metal processing companies. Founded in the 1930s as a furniture factory, it changed direction in the 1950s to nail production before starting sheet metal production in the 1980s.
Manufacturing sheet metal parts can be particularly difficult. The production cost per component is very low compared with other industries such as metal machining. This drives down the resources available to the quality control process, even though sheet metal parts are often used in the most demanding applications such as aerospace or automotive or in very large production runs, all of which require inspection.
Even before the 1986 NASA Space Shuttle disaster that took the lives of seven crew members, o-ring manufacturers throughout the world have had to place a strong emphasis on the quality of the goods they produce, both in terms of dimensional accuracy and longevity.
Electric lamination inspection is a particularly difficult and demanding application to which the traditional range of metrology equipment is not well suited. Unfortunately, the inspection of laminations is not optional. The tolerances are quite tight and some of the reference features are quite small. The measuring machine must therefore have a very good accuracy and feature resolution.
Gasket and seal inspection is a particularly difficult and demanding application. With the advent of spiral wound, double-jacketed and kamm profile gaskets, gasket inspection has become a lot more difficult. The latest generation of gaskets are no longer manufactured from a simple 2D sheet, they are now a complex 2.5D or even 3D assembly made from a variety of flexible and solid materials.
Daniel Kannegießer, a Mechanical Engineer from Zumtobel told InspecVision we 'were measuring by hand before and this was really time consuming, it was also too inaccurate, slow and not traceable'. These problems now have been addressed with the purchase of their Planar scanner.
Operations Director, Matthew Whitwam stated that "customers began to demand more detailed inspection processed be implemented", and Whitwam's manual methods were not adequate for inspection. This made the purchase of a computerized measuring system to satisfy customer demand a necessity.
Inspecting complex parts manually is extremely time consuming and the "components are quite impossible to be inspected with manual tools" stated Mr. Capitanio. In contrast the Planar system is the fastest 2D inspection system of its kind in the world, which made Verona Lamiere's decision to purchase one easy.
Stephen continues to explain that they 'choose the largest model (P360.50) with dual cameras, so we are able to measure longer parts, up to 118" in length. This reduces the amount of time that we would spend "scanning" and merging the parts in our inspection process.
The Quality Manager at Siemens informed InspecVision that before they purchased the Planar they were 'inspecting parts manually'. Their manual method was very time consuming. They have found that inspection of the parts is 'more effective by using Planar machine than the old manual method used'.
According to Mike Dreikosen Senior Manufacturing Engineer at Maysteel, "Ensuring the quality of our product is essential at Maysteel. We have over 16 CNC turret punching machines, 2 turret/laser combo machines and a free standing laser machine. We use the InspecVision Planar machine to verify the output from all these machines!"
They required a more accurate way to check the 22 to 10 gauge (0.7 to 3.0 mm thick) components after they have been routed and drilled. This is being driven by increasing use in aircraft manufacture of predeterminate assemblies. They require components whose machined features are so precise that they fit together perfectly, without having to use jigs on the factory floor and ream out pilot holes.
Unfortunately, the existing inspection methods such as CMMs are slow, extremely complicated and expensive both to purchase and to run. In addition, conventional CMMs can only be used to measure a limited number of points. Due to the quality demands of industries such as automotive and aerospace, inspection is not an option.
Auto Heinen was acquired by the Scherer Group, but were originally founded in 1933. They manufacture and nish aluminium die-cast parts for leading Automotive companies such as Aston Martin, Ford, Jaguar Land Rover, Continental and Schaef er Gruppe. Their company's dedication to quality management meant that they wanted to find a fast and accurate method of checking their components.
