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.
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.
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.
GE Appliances (GEA) has been designing and manufacturing consumer appliances for over 125 years. The iconic brand, headquartered in Louisville, KY, employs nearly 6000 people, a number that rose to 12,000 employed globally after its acquisition by Haier, making the company part of the largest appliance manufacturer in the world.
More and more manufacturers are seeing productivity as a crucial factor to their business success. In the meantime, business models are changing from the large quantities and few variants to small quantities with frequently changed variants. This change requires high flexibility during production.
Manufacturing got smart when companies figured out how to make products in one market and sell them in another. Today, we call this supply chain logistics. But somewhere along the way, the innovation chain connecting supply (manufacturing) and logistics (the supporting infrastructure) started to diverge.
Makers of workholding devices face a moving target. The machine tools they work with are changing. There’s more high-speed machining. More high-feed machining. More multi-axis machines. New uses of coolant to reduce temperatures during cutting operations.
Hard turning has long been used for finishing when it comes to high-volume applications. Now, tooling suppliers have pushed cubic boron nitride (CBN) insert technology further, with geometric innovations that further increase the efficiency—and cost-effectiveness—of hard turning.
The keynote for Haimer USA’s May Open House at its headquarters in Villa Park, Illinois, was delivered by President Brendt Holden, who remarked that his company’s toolholding and related products are designed to provide consistent setup for their customers’ machining jobs.
You don’t have to look too far to find tooling presetters that fit the machining requirements of just about any size shop. The value of off-line tool presetting—rather than stopping machine spindles to touch off tools as machines sit idle—continues to prove itself invaluable, especially to the smallest first-time user shops.
