Robots aren't just for movies or kids' toys

The Rock Island Arsenal now owns one of the few seven-axis machines in the world. It can perform a series of functions all at the same time.

Few Quad-Cities families have Rosie the Robots to do the laundry, but robotics and computer-controlled machines are standard at many Quad-Cities industries.

They are used in every kind of manufacturing imaginable.

-- M. A. Ford Manufacturing, in northwest Davenport, uses computer-numeric control (CNC) machines to make industrial cutting tools.

-- Seaberg Industries, in Rock Island, uses CNC machines to make machine parts for Caterpillar and other companies.

-- Olsen Engineering, in Eldridge, uses CNC machines to make pins and other precision parts for clients like Case Corp., Deere & Co. and others.

-- Modform Inc., in East Moline, uses CNC lathes and mills to make parts for manufacturers like Harley Davidson, Caterpillar and Deere & Co. Modform vice president and general manger Ken Huss said the flexibility of the programmable machines saves money, because one machine can do the work of many.

``The program tells the machine what to do,'' Mr. Huss said, ``so it can make an ashtray on this pass and a coffee cup on the next, if you wanted.''

Genesis Systems Group, in Davenport, has made robotics its business. The company makes robotic systems for arc welding, spot welding and thermal cutting systems.

The Rock Island Arsenal is one of the most significant local users of CNC and robotics technology in manufacturing. The arsenal has CNC machines for milling, turning, grinding, cutting and other tasks.

The arsenal first began using computer-controlled machines in 1958, according to Howard Husson, chief of operations support division. His division supplies tools, programs and work methods for the manufacturing operations.

Like the computers that control them, CNC machines have evolved greatly over the years, but basic operating principles remain the same. Computer programs are downloaded into the CNC machine's memory, and the machine then repeats the programmed motions over and over.

Machines controlled by computers rather than operated conventionally by humans have many advantages, Mr. Husson said. One of the greatest is cost savings.

CNC machines make parts faster, because time needed to set up the machine and run through the production schedule is reduced by 40 to 50 percent over conventional machines.

The machines also can perform many tasks, such as cutting lines or punching holes, at once, Mr. Husson said. Conventional machines perform one task at a time, which increases the likelihood of measurements being off.

CNC machines also are highly accurate, often to plus or minus one-thousandth of an inch, he said.

``Overall operations are more controlled and consistent,'' Mr. Husson said, ``because they are running off a program, rather than an operator.''

The arsenal has used robotic technology for about 15 years, Mr. Husson said. Robotics basically mimic a person's arm motion, enabling a machine to perform many of the same tasks human operators once did. They often have greater ranges of motion and can bend and twist where human arms cannot.

Robotics often are used to perform tasks that would be dangerous for people to do. The arsenal uses robotic arms for welding, painting and forging, Mr. Husson said. Robotic welders and forgers do not need protection from burns, and robotic painters do not have to be protected with breathing apparatuses.

Robotic forgers, for example, can pick up hot chunks of metal straight from a furnace and stick them into a hammer, Mr. Husson said. They also can lift several hundred pounds at a time.

Like CNC machines, robotic arms produce absolutely consistent work, Mr. Husson said. Once programmed, robotic arms will repeat a motion every time, exactly.

CNC machines also have disadvantages, though, Mr. Husson said. They are more complex than conventional machines, so they need more maintenance. Also, the machine operators must be more skilled than workers who run conventional machines.

Plenty of training is available, though. Black Hawk College professor Mike Drefchinski has taught classes on setting up, programming and running CNC machines since 1967.

Many more industries use CNC technology today than did decades ago, Mr. Drefchinski said.

``When I started teaching, CNC was primarily used in defense and aircraft,'' he said. ``Now it's pretty much just required to be able to function in a manufacturing environment.''
