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.

Intelligent factories have existed since manufacturing’s historical inception, but intelligence—defined as the acquisition and application of manufacturing knowledge—resided only with the factory’s staff.

Manufacturers are always looking for signs of what the economy and the business outlook have in store for them. Since the election of President Trump and, more recently, passage of the tax reform law in December, confidence among businesses of all sizes has been overwhelmingly positive.

Despite the addition of more than 750,000 CNC mills in the past 15 years in the US, CNC machining job shops often hover at the bottom of the totem pole, where there’s little room for error as most bids are won by a 1–2% price variance.

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.

Industrial lasers require cooling to remove excess heat generated in the resonator power electronics and the optics system. The type of cooling required is determined by laser wattage, resonator efficiency, resonator and optics temperature requirements, and ambient temperature.

While laser marking and engraving are well-established processes, innovations and investments in the sector are continuing to push performance boundaries.

From producing lithium-ion batteries to processing sheetmetal, new laser welding systems are “pushing the envelope” of light absorption, beam control, speed and programming flexibility.
