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).

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.

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.

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.

It’s said you don’t know where you’re going if you don’t know where you’ve been. For Industry 4.0 and advanced manufacturing, digital libraries provide that map.

On race day, everybody sees the race on TV, but behind the scenes there’s a competition going on between shops where time is everything, according to Matt Gimbel, Team Penske’s production manager.

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.

Manufacturing companies are responsible for creating products to deliver to their customers. Of course, a production system needs to be in place to understand how much product needs to be made.

With advances in material sciences and the ability to design composite parts with new virtual software technology, cutting tool manufacturers are being challenged to continually evolve and develop solutions for these versatile materials.

At Lyall, we’ve been manufacturing components in the natural gas distribution industry for over 45 years, and we’ve spent the past 16 of those years implementing lean manufacturing principles in everything we do.
