Carbon fiber solution enables use of smaller payload equipment and cuts the robot investment in half.
Bilsing Automation, a leader in the development and manufacturing of modular tooling systems, has recently proved out the value of its carbon fiber tooling solutions on a recent project where it saved an integrator over $2.7 million in robot investment by enabling use of smaller payload models. The project involved 18 robots that were unable to meet processing requirements when equipped with aluminum end-of-arm tooling.
Bilsing was able to design a 17' x 5' x 2' "H"-style NAAMS carbon fiber frame that reduced the tooling weight by half so that the robots had capacity to hold and move entire automotive body sides at required speeds and positioning. Prior to Bilsing's solution, the company was looking at potential investment in larger robots that were over two times the cost.
In this particular scenario, the robots in question had a payload capacity of 400 kg (1,072 lbs) and the body sides weighed approximately 165 kg (442 lbs). Although the robots had capacity for the combined weight of the aluminum tooling and the workpiece, the inertia load (forces required for load acceleration/ deceleration) failed in many instances. By using carbon fiber, Bilsing was able to cut the tooling weight in half for a combined weight of 288 kg (635 lbs.).
"This application illustrates the great ROI you can achieve using carbon fiber," said Bilsing Automation general manager Benjamin Pauzus, Jr. "Although initial investment is more expensive than steel or aluminum tubing stock -- the costs, in this case, were immediately and dramatically offset by the savings achieved through a smaller robot model."
Pauzus is quick to point out that a project needn't be of this caliber for savings to be achieved through application of carbon fiber. Even a single-robot application would have achieved over $150,000 in savings. Additionally, carbon fiber tooling can help achieve productivity gains of up to 20-percent while helping to extend the service life of robots due to improved harmonics.
Another significant fact is that the carbon fiber "H" frames were developed to meet dimensional specification for body shop applications as designated for NAAMS (North American Automotive Metric Standards) and are able to interface with NAAMS-compliant components. Bilsing can match NAAMS requirements with a carbon fiber solution, resulting in a stronger and lighter solution for improved productivity.
