Rich Curless knows where machine tool customers are headed: They want an operator to be able to walk up to a machine, push the start button and have that machine make all its own decisions on how to start pumping out the parts automatically.
Curless, who leads R&D and product development for Cincinnati Lamb, Hebron, Ky., says that is the goal of an industry/government coalition on smart machines. Initially spearheaded by the National Institute of Science and Technology, the group has evolved into Smart Machines Coalition. Included are the National Center for Manufacturing Sciences, the National Center for Defense Machining and Manufacturing, and the Association for Manufacturing Technology (AMT).
Machine intelligence is part of an evolutionary process that was well under way by 1970, observes AMT's Paul Warndorf, vice president, technology. He's referring to how punched-tape numerical control (NC) -- which originated in the mid-'50s was transitioning to computer NC in the 1970s. Instead of the NC machine being controlled by a punched paper tape, the source of the control directives evolved to be a computer hard drive. Another epochal event was the innovation of the programmable logic controller by Dick Morley to replace relay logic, says Warndorf.
Also, globalization and multi-tasking machines remade the course of machine tool history during the 1970s and 1980s, notes Cincinnati Lamb's Dan D. Janka, president. "With the multi-tasking concept, one setup on one machine could do the work that required three setups on three machines," Janka says. The emerging presence of Japanese firms such as Mazak and Mori Seiki signaled the globalization of the U.S. machine tool market.
