END USER: Trek Bicycle Corp., (920) 478-2191, www.trekbikes.com. CHALLENGE: Improve material yields and speed generation of nesting patterns for carbon fiber composite parts. SOLUTION: CAM software that automatically generates nesting patterns to maximize material yields. SOLUTION PROVIDERS: JetCAM International s.a.r.l., +44 870 760 6469, www.jetcam.com

Known for its professional race-winning and mass-produced bicycles, Trek Bicycle Corp. manufactures high-end carbon fiber bicycle frames at its Waterloo, Wis., facility. With global demand for (and thus cost of) carbon fiber composite materials increasing, engineers there began investigating ways to streamline nesting of composite parts to be knife cut on the plant’s three Gerber machines.

“We were manually generating static nests,” explained Ben Fisher, product manufacturing engineer. “Static nests could take several hours to create and were often inefficient, depending on the creator and the part shapes.” Therefore, the company looked for a way to decrease nesting time, maximize material yield and possibly generate dynamic nests for daily production. “We could not have done dynamic nesting effectively with the manual nest building method,” Fisher added.

Nesting software helped Trek increase material yields 5 to 15 percent and automate nesting of carbon fiber composite parts for knife cutting.

After narrowing the field to two finalists, Trek chose CAM software from JetCAM International s.a.r.l., Monaco. The package delivered a good mix of automation and human interaction, and lets users set cutting speed based on the number of layers of composite material to be cut per pattern, Fisher noted.

Claude Drehfal, a Trek manufacturing engineer who also worked on the project, said, “Based on sample nests of common parts, we were able to justify the cost of the software with less than 1-year payback. Also, the JetCAM reseller allowed us to fully evaluate the software to ensure it met our needs.”
