Nobody's perfect. Even the best trained, most experienced assemblers can make mistakes on the line, especially in high-mix production environments. Fortunately, a variety of software products are available to help prevent assembly errors.
For basic welding jobs, companies often rely on blueprints, tools and tape measures to build and weld the parts. However, when using these conventional tools, there's a high risk of mistakes being made and, at the end, having to break the parts loose, which is expensive and time consuming.
There are good and bad aspects to repetition. On one hand, it's a proven way to learn to expertly perform a task. On the other, it can lead to physical problems like carpal tunnel syndrome, and bad arthritis in the hands, arms, legs and back.
The notion of making products close to where you sell them may be coming back into vogue among manufacturers worldwide, but it’s nothing new to Japanese tractor manufacturer Kubota. The company started manufacturing here in 1988, and it has continued to invest heavily in its U.S. presence ever since.
Manufacturers of complex products, such as engines and transmissions, have long been using radio frequency identification (RFID) technology to error-proof their processes, document quality, and deal with high-mix production.
Construction equipment, farm tractors and other off-highway machines need more than just diesel engines, big tires and metal tracks to operate. They require hydraulic mechanisms to steer, raise booms, open buckets or tilt blades.
Multistation automated assembly systems are a wonder to behold. A well-designed system can mass-produce hundreds of assemblies per minute with minimal human intervention.
