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.
Micro components continue to shrink in size, demanding ever-greater precision and improved handling of parts with sub-micron-sized features. New approaches in micro machining technology include higher-precision systems from traditional micro machining developers, as well as techniques using additive manufacturing processes and semiconductor wafer-scale technology on the smallest of micro parts.
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.
Metrology-grade laser scanners are expanding their range of applications. New users are finding the main attractions of laser scanners—speed and ease of use. What prevented more widespread use in the past were laser scanners’ perceived tradeoffs. Using one usually meant sacrificing accuracy or working with noisy data.
Fiber laser welding is all about control of the process, according to Kurt Magedanz, laser process engineer at Ace Precision Machining Corp., Oconomowoc, Wis. With its new Laserdyne 430 systems, Ace Precision has made huge strides with weld quality while reducing operator intervention in the process.
Simcenter Testlab enables better usage of test-based data, from design and simulation to validation and certification.
Tool coating is ubiquitous. The variations are dizzying. And, we’re at an inflection point in the technology in the U.S. So, whether you’re a tool user or a tool manufacturer, it’s a good time to dive into this topic.
Adaptive Milling. Dynamic Motion. hyperMILL. Profit Milling. VoluMill. Waveform machining. If you’re one of the lucky people who machines parts for a living, chances are about 50-50 that you’re using one of these or a comparable high-performance programming technology.
