If an existing operation is not safe to employees, automation may be more desirable.

Automation is especially attractive in processes where manual interaction can result in quality or safety issues or in situations where a human worker simply can’t operate at the pace of a machine. The key is to identify which processes are most suitable for automation and can generate the highest return on investment. Almost any manufacturer can benefit from automating certain steps in the manufacturing process. This doesn’t diminish the value of automation, however. “If this value exceeds a two-year return, the investment is less desirable.”Įven if the investment does make sense, the products may have too much variation to effectively automate 100 percent of the process. “If a client requests a lights-out manufacturing system, satisfactory criteria include determining what the relationship between the cost of the equipment versus the return of investment is in terms of labor, quality, scrap, and production-throughput predictability,” Gratschmayr says. If a machine passes these three steps, it’s deemed viable for continuous operation.īut even if the machines can handle the continuous workload, going lights-out may not always be the best investment. MWES also performs a failure mode and effects analysis (FMEA) to evaluate potential failures, as well as a flow analysis for incoming and outgoing product. C pk is a measure of process robustness, and 1.67 is a generally accepted measure for “four 9s” capability that is, 99.9999 percent of parts will meet requirements, which provides a failure rate of one in a million. To test whether a machine is capable of continuous operation, MWES first determines whether the process capability ( C pk) exceeds 1.67. Scrap rates and field failures are also reduced.” Energy requirements for HVAC control systems and lights are reduced. “Some of the advantages to implementing lights-out manufacturing are reducing and stabilizing labor costs to be reliably consistent,” says MWES Senior Sales Engineer Peter Gratschmayr.

Wisconsin-based Midwest Engineering Systems (MWES) is a provider of custom machine design and automation solutions to enable manufacturers to go lights-out. But to entrust manufacturing operations to the machines, companies must first have their automation systems in place. What FANUC started is becoming more commonplace in factories in the United States and abroad. With customers such as Tesla Motors and Apple and a February 2015 pledge of $1 billion to expand its operations, job stability for FANUC’s self-replicating robots is at an all-time high. Presently, FANUC produces between 22,000 and 23,000 CNC machines per month. The complex houses 22 factories where a huge population of honeybee-yellow robots replicate themselves 24 hours a day, seven days a week. FANUC Robotics America Vice President Gary Zywiol said about FANUC’s capabilities, “Not only is it lights out, we turn off the air conditioning and heat, too.” At FANUC (factor automated numerical control), robots produce other robots without the presence of humans. Probably the most well-known lights-out manufacturing facility is FANUC in Japan.

Lights-out manufacturing is a term that describes manufacturing operations and factories that do not need humans physically present to run properly: The factory can run “with the lights out.” Despite concerns from science-fiction authors, lights-out manufacturing operations do exist. But if you ask most people how robots, automation systems, and lights-out manufacturing are affecting the products they buy, they probably won’t have a clue. The narrative follows the attempts of humans to regain control of production-possibly a forward-thinking cautionary tale?ĭystopian visions may be entertaining, but what are robots really producing on their own? Most people in the general public have an awareness that robots are being programmed to defeat humans at games like chess, poker, and Jeopardy.

The “autofacs” become increasingly autonomous in deciding what to produce and why.

The story revolves around a post-apocalyptic world where the human survivors have lost control of self-replicating robots designed to provide them with resources. Dick’s short story “Autofac,” first published in the November 1955 issue of Galaxy magazine. “Naturally, Man should want to stand on his own two feet … but how can he when his own machines cut the ground out from under him?”
