At Cessna Aircraft Company, Wichita, Kansas, a mission critical
machining cell consisting of three Trumpf routers was bogged down due
to persistent control problems. The cell produced 60% of the parts used in
Cessna planes. The backlog in the cell forced Cessna engineers to outsource
work at a cost of a million dollars a month.
Solving the problem was essential. The trouble was, Cessna engineers didn't
want the same old control retrofit choices theyd already
proprietary, and closing off each machine into an isolated unit.
When they discovered MDSI's OpenCNC® software CNC, they recognized the
- OpenCNC was completely independent of proprietary hardware.
- It ran on Microsoft Windows NT, from a single PC, with a single processor.
- OpenCNC was all-software and completely open: The Cessna team could network
the machines, access them remotely from the field, integrate third-party
software technologies, and upload and download part programs in seconds.
Once the routers were retrofitted with OpenCNC, the Cessna engineers saw
- The routers improved feedrates and produced smoother part finishes. Machine
utilization at the cell more than doubled.
- Uptime on the manufacturing cell was maximized to the point that all
outsourcing was stoppedsaving Cessna one million dollars a month.
- Thanks to OpenCNC's patented real-time database for the collection and
distribution of machine production and process data across a network, the
Cessna team was able to identify and improve a key manufacturing process,
the riveting/scrap removal process.
