Cloud-based computer applications are all around us and continue to expand and influence many aspects of our personal and professional lives. Digital, or computer-based machining (CAM) is no exception.
Although CAM and computer numerically controlled (CNC) technologies have been with us for several decades, cloud-based methods are relatively new, but evolving at a rapid pace.
The first NC machines were built in the 1940s and 1950s, based on existing tools that were modified with servomotors that moved tools or parts to follow points fed into the system on punched tape. These early servomechanisms were rapidly augmented with analog and digital computers, creating the modern CNC machine tools that revolutionized machining, and more recently, cloud-based processes.
Held every two years at McCormick Place in Chicago, the International Manufacturing Technology Show (IMTS) is the one of the largest (over 110,000 attendees), most comprehensive (~2,400 exhibitors), and longest (six days) manufacturing shows conferences in the world, certainly North America. This year’s event marked IMTS’s 31st edition. First timers and long timers are overwhelmed by the sheer size of this event. At over 1.3 million square feet, you better dress comfortably and prepare for an overload of manufacturing technology sights and sounds.
Because IMTS is so comprehensive and massive, planning is everything, and as you walk around the various pavilions, you start to get a sense of trends and likely future impact of just about all of the technological aspects of design, engineering, and manufacturing.
Below are the major manufacturing trends that I experienced this week. Starting next week I’ll detail what I considered to be the most significant technologies and products showcased at IMTS this time around. Next week, I’ll also go over the major software developments that were introduced — mostly CAM, but some significant stuff.
A couple of weeks ago I attended the Hexagon Global Network (HxGN) 2015 Live conference. Although not held in my favorite destination, Las Vegas, this was an opportunity for my first direct exposure to Hexagon. In a word, I was not disappointed. In fact, the experience went far beyond my modest expectations that I had before attending the event.
I went to HxGN specifically for the metrology (science of measurement) portion of the conference with regard to sensing, inspection, QA, and reverse engineering applications – in other words what Hexagon Metrology is all about. However, metrology was not the only area represented, as the company known as Hexagon AB also has a huge presence with its hardware, software, and services in other industry segments, such as geospatial (GPS and surveying); process, power, and marine (PP&M); and security, government, and infrastructure (SG&I). It was a lot to take in and I focused on industrial metrology and related technologies – sensors and software used for optimizing manufacturing processes and throughput.
Founded in 1992 and headquartered in Stockholm, Sweden, Hexagon AB has offices in 46 countries, 15,000+ total employees, and is R&D focused with 11% of net sales and more than 3,400 employees invested in R&D. The industrial side of Hexagon AB, known as Industrial Enterprise Solutions (IES), that includes manufacturing and industrial plant facilities accounts for about half of the company’s sales. Roughly one third of Hexagon’s business is derived from metrology.
