”Never before has an automaker brought this combination of joining techniques together for a single vehicle,” says Travis Hester, CT6 executive chief engineer. The two framing processes were choreographed to compensate for different microscopic vibrations.
The robots are mounted above and beside the vehicle and can also reach beneath it.
To weld both the inner and outer vehicle frames, 28 robots descend on the vehicle body in two separate framing stations, joining the body-in-white together from all angles. Aluminum arc welding and structural adhesiveĪmong the five techniques, the CT6’s engineers were able to select the best joining method depending on material combination and body location (for machine equipment access).Flow drill screws, which are able to join different types or materials and used in conjunction with adhesive.Self-piercing rivets, which are able to join different types of materials together with a clean appearance.Aluminum laser welding, which creates a seamless joining of exterior panels.Material joining techniques prominent in the body construction of the CT6 include: GM developed some of those systems for the aluminum-framed Corvette and the Volt, which makes extensive use of lightweight metals in exterior panels.Ĭombining different types of joining methods, the team overcame previous manufacturing difficulties involving the joining of traditionally dissimilar materials, while still allowing the engineering team to optimize every panel for its desired purpose. The CT6 will use high-strength steel and aluminum in its body and external structures, requiring mixed-material technology. “We have invested $300 million in the Detroit-Hamtramck Assembly plant to make this possible.” “For the Cadillac CT6 we have developed additional new body construction techniques and technologies allowing various types of advanced and lightweight materials to be combined within the manufacturing environment like never before,” Cadillac President Johan de Nysschen says at the Washington Auto Show. The fully automated, roughly 138,000ft 2 shop is dedicated to the manufacturing of the high-end luxury sedan. A new body shop with new tooling and advanced technologies – including 205 robots – has been added to the plant. The CT6, which goes on sale in the fourth quarter of 2015, will be built at the Detroit-Hamtramck Assembly plant, using a unique combination of joining techniques, a first for any General Motors’ model. – Cadillac will apply lessons learned from the Chevrolet Corvette sports car and Chevy Volt electric vehicle, using advanced mixed-material manufacturing techniques to build its new CT6 sedan, allowing creation of a large luxury sedan with the agility and efficiency of a smaller vehicle.
(We) have come to the conclusion that in order to further create corporate value, it will be the best solution that they are operated together in an integrated manner.” In its filings, executives with the Japanese portion of the machine tool company say, “The business collaboration between CO (the Japanese portion of the company) and AG (the German side) has brought more success than was expected at the time of the start of their collaboration. Germany’s DMG merged with Mori Seiki in 2009. The German portion of DMG Mori Seiki says it will respond to the tender offer after all documents have been filed with German financial regulators. The Japanese portion of the company expects to announce a settlement of the issue by June. Gaining all German shares would cost $1.9 billion. Getting enough stock to cross the 50% mark would cost $633 million, based on the offer. The Japanese side of the company currently owns 24% of the company, and it has made its tender bid for at least 50% of the combined company. Ltd.’s bid for DMG More Seiki AG represents about a 7.5% premium on the German company’s stock price from Wednesday’s close. Cleveland, Ohio – The Japanese portion of machine tool company DMG Mori Seiki has bid as much as $1.9 billion to take over the German half of the combined company.ĭMG Mori Seiki Co.
