Ogihara Leads Supplier Industry Using Optigo by Cognitens
Ogihara - USA
O.A.C. operates in the US from Howell, Michigan. Ogihara’s production facilities provide critical parts and assemblies to General Motors, Ford and DaimlerChrysler as well as to several Japanese “transplants” across North America.
As part of the Ogihara tradition both O.A.C. facilities along with more than a dozen other Ogihara facilities around the world share common processes for ensuring lean and streamlined operation. Common processes help Ogihara develop and manufacture more cost effectively while ensuring the best quality for the customer at all times.
From reactive to proactive
In 2001, as part of the ongoing effort to improve operational performance, Ogihara conducted a thorough evaluation of their quality processes and systems. Ogihara’s objective< was to raise their quality standards even higher by transforming reactive quality processes to proactive ones, thus considerably lowering customer reported quality issues and maintaining best quality ratings. As a result of this evaluation, Ogihara’s engineers developed a unique process planned to be fully integrated into their product development and manufacturing program.
This new comprehensive quality process called for an advanced non- contact dimensional measurement system which could be easily operated in a shop floor environment and help resolve quality concerns using root cause analysis methodology. However, it seemed that at that time, Ogihara had developed a process which was more advanced than the available technology and there was no product to be found which could fully meet the various Ogihara requirements.
Evaluations find a versatile solution
Following a long period of evaluations and benchmarking, Ogihara identified CogniTens’ Optigo as the only non-contact measurement system capable of meeting the demanding Ogihara criteria. Throughout tests and trials Optigo’s performance proved it was suited for versatile operation on the engineering and production floor and highly useful in supporting multiple measurement activities from die tryout to assembly tool adjustment and quick quality analysis of parts and sub-assemblies.
Initial implementation of the CogniTens products in the Howell facility took only a couple of months to complete. Then a joint team consisting of Ogihara, CogniTens and customer representatives worked together to further integrate this new solution into dozens of business processes based on Ogihara quality process guidelines. As a result of this joint effort, within a year, the new Ogihara Quality process was further enhanced and fully implemented in daily plant operations using CogniTens products.
Following the successful implementation in the Howell, Michigan facility, Ogihara expanded its use of CogniTens Optigo based solution to the Birmingham, Alabama plant producing stamping parts and sub-assemblies for a large OEM assembly plant. CogniTens’ solution was rapidly implemented in the Birmingham facility based on the experience garnered during the first stage and maintained the Ogihara tradition for process commonality and standard methods between the two facilities.
Ogihara’s vision realized
Combining Ogihara’s unique processes and quality methodologies together with CogniTens dimensional measurement platform and software products resulted in the realization of the Ogihara vision for a fully proactive quality system.
Today Ogihara utilizes the Optigo based solution throughout the die build and tryout process, in supporting part approval for production (PPAP) activities and standard data submittals to the OEMs, for re-engineering an existing part or tool to support vehicle “Face Lifts” as well as in assembly processes.
Unique “Functional Build” process
Using Optigo, a fully portable dimensional measurement platform and CogniTens software products Ogihara’s Quality department has developed a unique Functional Build process to filter out possible assembly problems even before building the tools for the actual assembly operations.
Ogihara reports several benefits in using the CogniTens dimensional measurement solution. The times to measure a panel and compare results to design intent were reduced from a full day using a CMM to a couple of hours using Optigo. Cost savings in root cause assembly quality analysis were realized. Typically, customer quality concerns are resolved in less than half the time compared to CMMs by using Optigo’s CoreView results for effective communication, analysis and resolution. In addition, tool maintenance operations were optimized using proactive quality evaluation of both tools and produced parts and assemblies.
Meaningful dimensional data
“Optigo’s full surface measurement, virtual assembly analysis and highly accurate feature measurement opened countless applications which CMM just could not support”,
says Steve Peca, Quality Executive at Ogihara America. “With Optigo, we’re able to get meaningful dimensional data on automotive panels and assemblies, which support our
Total Program Management methodology. Using CogniTens full 3D measurement and meaningful CoreView format results we can also see where the forming and assembly
tools are deteriorating and schedule maintenance checks and upgrades.
