Manufacturer turns to the cloud

Tech Manufacturing Co. already was running CNC machine tools 24/7 when the aerospace parts manufacturer sought Brea, California-based Moxa Americas Inc.’s help to raise production capacity, reduce lead times for clients’ largest and most urgent orders and expand the useful service life of existing machines. The Wright City, Missouri, company machines parts made of aluminum, titanium, Inconel, stainless steel and beryllium copper with tolerances as tight as 1.27 µm (0.00005″) for helicopters, as well as military, remotely piloted and commercial aircraft. Customers include Boeing Co., Lockheed Martin Corp., Bombardier Inc., Embraer SA and Gulfstream Aerospace Corp.

“We needed a better understanding of how our machines were actually performing for us in real time,” said Jerry Halley, chief engineer at Tech Manufacturing, which has about 70 employees. “Live and historical machine performance data would also help us identify technical or process issues that were detrimental to productivity.”

Purchasing additional machines would have increased production capacity, but he said the company wanted a “smarter,” more efficient approach that didn’t require a large capital investment. Tech Manufacturing determined that a CNC monitoring system was the smarter way, which would enable the company to collect, analyze and visualize necessary performance metrics.

Before taking the next step, however, Halley said he carefully weighed the productivity gains of a system against the cost and effort of deployment, especially if it involved a new, unfamiliar server-based information technology infrastructure. The ideal system would be deployed easily without specialized IT equipment, knowledge or effort, and the system would not require repeated software installation, updates or configuration.

To assist with integration of a cloud-based CNC monitoring system, Tech Manufacturing turned to Shop Floor Automations Inc. in La Mesa, California. Each of Tech Manufacturing’s CNC machines was connected to the existing local area network to avoid adding IT infrastructure.

For legacy machines that did not have an Ethernet port, Shop Floor Automations provided an easy-to-deploy solution based on Moxa NPort W2150A and W2250A wireless device servers, which permit communications software to access serial and Ethernet devices over a wireless LAN. Being wireless, the device servers, which can be moved from place to place, required far fewer cables and let users roam among several access points.
