Solutions for Difficult Machining January 1, 2009 The machining challenges for two of the most advanced concepts in cutting tool materials are pretty well known. Cubic boron nitride (CBN) tools of varying designs are being used to cut hardened ferrous metals with or without interrupted cuts, as well as welded and clad metals.
Tooling and Workholding August 1, 2006 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 Certifications in the Knowledge Age May 7, 2018 Technology is changing ever more rapidly. Sometimes this means topics learned in engineering or technical school become obsolete. Whole new fields emerge within a few years, so that even those with freshly minted educations suddenly find themselves faced with new challenges.
Micro Cutting Tool Options Expand as Applications Increase May 2, 2018 Solid-carbide micro cutting tools about the diameter of human hair or smaller—some producing parts visible only under a microscope—are making a huge impact on manufacturing highly advanced electronics, automotive and aerospace fuel injection systems, and medical instruments and implants.
Liquid Nitrogen an Alternative to Traditional Coolants May 30, 2018 Cryogenics offer an alternative to traditional liquid coolants when conventional cooling methods can’t or don’t do the job well enough.
More Shops Take the ‘Through-Way’ for Coolant Applications May 30, 2018 If John Winter of toolmaker Sandvik Coromant (Fair Lawn, NJ) were to start his own machine shop, all of his machines would be equipped for through-spindle coolant (TSC).
Optical Metrology in Three Dimensions May 29, 2018 Basic trends in modern manufacturing are driving growth in 3D optical metrology. “One is the highly complex and high-tech material that manufacturers are using today. For example, in the aerospace turbine blade market, they simply cannot touch the part like they used to—the surface finish of the material is too readily affected by any kind of contact metrology."
Replaceable Tip Drills Offer Versatile Design Improvements April 24, 2018 Since their introduction about 20 years ago, replaceable-tip drills have become increasingly accurate and cost-effective alternatives to solid carbide units.
Workholding Solutions to Reduce Costs, Increase Throughput April 24, 2018 At the Nirvana Machine Shop on planet Perfection, every workpiece is clamped to a custom-built fixture mounted on a dedicated machine tool. Each workpiece is dimensionally identical to the one before and the one after. All the fixtures are totally automatic—instantly positioning, clamping, machining, inspecting, and releasing the part with the ultimate precision.
Big, Heavy, Awkward Parts Need Workholding, Too April 23, 2018 If you’ve ever seen industrial wind turbine components on the back of a flatbed truck rolling down the highway, you have a good idea of what a large, heavy, difficult-to-handle workpiece is. For example, with a single blade on the GE 1.5 mW turbine being almost as long as a football field, the entire blade assembly weighs about the same as 36 small cars.
