Shrink-fit toolholding is a simple concept—an induction coil is adjusted and fits over the top of the toolholder. The induction coil heats the toolholder end of the shrinker, expanding the inside diameter, which opens the engagement bore (IDs of shrink-fit toolholders are smaller than the shank diameter of the cutting tool).
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.
Industry veterans often say the makers of machine tools, cutting tools, CAD/CAM software, and other components push each other in an endless feedback loop to deliver ever faster cutting speeds in ever harder materials. Lately it’s the cutting tool manufacturers who seem to be leading the charge. Let’s see what they’re up to.
As machining has evolved, toolholders have advanced to include rigid, secure systems with anti-pullout protection. These advanced systems are needed to take on difficult-to-machine materials, such as titanium and heat-resistant superalloys (HRSA), and accommodate ambitious removal rates and long tool overhangs. Think of them as insurance against tool pullout and breakage—a situation nobody wants.
Four universities—Iowa State University, University of Minnesota, University of Wisconsin-Madison and North Dakota State University (NDSU)—competed in the inaugural 3M Industrial Adhesives and Tapes Disruptive Design Challenge (DDC) at 3M’s headquarters (St. Paul, MN), Friday, April 13.
In the early days at CNC Software, we saw that our Mastercam CAD/CAM system was only part of a larger manufacturing solution and that an open architecture foundation could allow seamless data communication with complementary devices and systems across the shop floor.
In the near absence of academic programs to teach undergraduate engineering students additive manufacturing, a California-based startup has stepped in to help fill the void through internships.
Machine tool orders began 2018 with mixed results, dropping from December but posting a surge on a year-over-year basis, the Association for Manufacturing Technology (McLean, VA) said in a monthly report.
I’m among the first to dive into the latest manufacturing innovations and see how they can improve our customers’ operations. Yet, I’m also among the first to advise them to pause and ensure that the fundamentals of their manufacturing processes are in place before adding something new into the complex mix of functionality and desired outcomes.
Machining aerospace materials is a challenging task. Not only are machining operations tightly controlled, a wide variety of workpiece materials are employed, including aluminum, titanium, and carbon-fiber reinforced plastics (CFRPs). The following is a brief guide to cutting tool options for successful machining of airframe components. All of the tools referenced are manufactured by Mitsubishi Materials.
