CLEVELAND, OH—November 12, 2012—Ramcel Engineering Company, Northbrook, IL, has received the 2012 Link Systems Process Control Award as part of the Precision Metalforming Association (PMA) Awards of Excellence in Metalforming. The company employs more than 50 associates and a wide variety of processes ranging from the automotive industry to electronics and hand tools.
Ramcel Engineering won the award for developing an automated cell to inspect parts that incorporates high-speed measurement accuracy and data management. A progressive lamination die is used to produce 21-piece laminated stacks. The part is used in an automotive electronic power steering application. It requires 100 percent inspection and requires several areas of measurement, including height and flatness, size and location of ID/OD, and size and location of magnetic window slots.
The RamcelVision automated cell uses a turntable to progress the product to each station, while a PLC keeps track of each part in the cell. Every location on the turntable is a clear glass insert that allows the part to be illuminated from underneath. The lamp emits parallel light that allows the camera to look “through” the part. The camera grabs a still image and begins to process all of the dimensions. The station after the camera contains three high-precision contact probes, which each take a measurement. A sensor detects the difference from the highest and lowest value and determines if the part is in tolerance for flatness. In the final station, if a part is rejected, it drops down into a crusher which guarantees that all rejected parts will never be mixed with a good product.
The Ramcel vision system performs more than 80 individual measurements per cycle. The application communicates with the PLC and the data server, feeding all collected measurements of every part into an Excel spreadsheet, giving Ramcel and its customer 100 percent traceability. Checking parts by hand would take 60-120 sec. each, whereas the automated cell has reduced cycle times to only 4 sec.
The Process Control Award is one of eight Awards of Excellence in Metalforming, presented annually by the Precision Metalforming Association (PMA). Sponsored by Link Systems in Nashville, TN, this award promotes the application of electronic-analog closed-loop process controls in the metalforming process by recognizing innovative electronic solutions implemented by a North American manufacturing company, which have resulted in significant quality, cost reduction and/or productivity improvements. Along with recognition in industry publications and at events, Ramcel Engineering Company will receive a $1,500 cash prize.
PMA is the full-service trade association representing the $113-billion metalforming industry of North America—the industry that creates precision metal products using stamping, fabricating, spinning, slide forming and roll forming technologies, and other value-added processes. Its nearly 900 member companies also include suppliers of equipment, materials and services to the industry. PMA leads innovative member companies toward superior competitiveness and profitability through advocacy, networking, statistics, the PMA Educational Foundation, FABTECH and METALFORM tradeshows, and MetalForming magazine.
