Demand for machining titanium for aerospace applications won’t abate any time soon. It is driving OEMs and the supply chain in the commercial airplane market to find ways to dramatically increase machining output. Whatever date you pick from now until 2030, there’s a sufficient backlog of commercial airliners for both structural and jet engine applications to keep spindles humming around the clock cutting titanium.
Until the middle of 2010, first-tier subcontract machinist, JJ Churchill, could produce turbine blades only if they had their fir-tree root-forms preground elsewhere, or if they were subsequently added by another subcontractor. No longer is this the case.
Why use a metrology device on or near a machine tool? It isn’t just useful for making sure a tool is present or monitoring tools for wear or breakage. On-machine measurement technologies can save time and money, by speeding up processes and eliminating extra personnel, and they are a critical step in the movement towards “lights-out” manufacturing.
The challenges to manufacturing as it evolves into the 21st century are now familiar, and impact how metrology must contribute. Manufacturers face uncertain production volumes with roller-coaster demand, shorter production runs and faster product development cycles. Automation, while alluring as a way to reduce cost, needs to adjust.
Overall, there are two overriding customer needs: reducing cycle time and machine downtime. They want higher feed rates and depth of cut for greater metal removal.
Glenn Bridgman describes the difference between his shop’s manual grinders and its newest state-of-the-art CNC ID/OD grinder, a Studer CT960 OD/ID from United Grinding (Miamisburg, OH), as “feel vs. facts.” Bridgman, president of Bridge Tool & Die (Buckley, MI), believes that manual grinding is a somewhat personal operation.
Machine tool orders fell slightly on a monthly basis in July but posted a solid gain compared with a year earlier.
May U.S. cutting tool consumption totaled $215.13 million, according to the U.S. Cutting Tool Institute (USCTI) and AMT—The Association For Manufacturing Technology.
GE Appliances (GEA) has been designing and manufacturing consumer appliances for over 125 years. The iconic brand, headquartered in Louisville, KY, employs nearly 6000 people, a number that rose to 12,000 employed globally after its acquisition by Haier, making the company part of the largest appliance manufacturer in the world.
It’s the machine tool acronym you never bother to put into words: CNC. And much of the time it’s probably OK to view your “computer numerical control” as a black box doing magic. But if you’re struggling with high-speed machining, need better surface finishes or higher accuracy, have training and retention problems, or want a better handle on your production efficiency, the answer just might be the latest iterations of those three little letters.
