The sheet metal fabrication sector is witnessing a dramatic change, and that change is being driven by CNC (Computer Numeric Control) technology. It is now the standard to work to in this industry—precise, efficient, and with a kind of versatility that offers many more available options compared to some traditional methods a fabricator might employ. Yet, even this very advanced technology continues to move forward and evolve, so what are the prospects for CNC Sheet Metal Technology? No doubt this very 21st-century technology will continue to penetrate the market more and more, offering even many more opportunities for fabricators to serve their customers.
CNC technology offers a major benefit in precision and accuracy for sheet metal fabrication. Operating with programming that is highly specific—within micrometer ranges—they yield artifacts that are consistent throughout and accurate to their intended design. The machines themselves are error-proof; errors that might have occurred in the programming stage are not present in a program that’s been vetted by a competent user. In the end, these machines give good quality, and they give it without any wasted effort or material.
The use of CNC technology in sheet metal fabrication results in astounding efficiency and productivity improvements. We owe these gains primarily to the introduction of CAD/CAM software, which lets us create not just 2D drawings but also detailed 3D models of the parts we work with. Thanks to these models, we can perform accurate simulations and design modifications that are both efficient and, for our purposes, quite easy to manage. The vacuum cleaner housing you see above was a part we fabricated using something close to these modern methods. We used to make them by hand, which is no longer the case.
Sheet metal fabrication achieved a new level of sophistication with the advent of CNC machinery. For one thing, the cutting, punching, bending, and other operations accomplished by these machines are performed with incredible precision. But CNC machines in themselves do not offer significant advantages over other punch presses and panel benders if they operate as dumb tools, without any real intelligence behind their operation. The real advantage of a CNC machine over other types of equipment is the intelligence that comes with the programming; CNCs are only as good as the programmers that operate them. Programmers must come up with a code that accomplishes the same objectives as a smart punch press or a smart panel bender—but at a fraction of the price.
CNC technology works hand-in-glove with automation and robotics—further extending the reach and power of these technologies. When robotic arms are used in conjunction with CNC machines, the automation of material handling, tool changing, and all sorts of other repetitive tasks becomes possible—and these tasks can be done with more safety and efficiency than ever before. Downtime between sequential operations can be reduced to virtually nothing, and the combination of these two powerful technologies can realize the Holy Grail of manufacturing: continuous production with lights-out capability.
The sheet metal fabrication industry can look forward to some very positive developments stemming from CNC technology. This technology has not one, but several, unique aspects that will permit it to serve in this particular capacity. First and foremost is the exceptional precision that CNC machining can achieve. This is followed by the efficiency that the machining operations can maintain, even when doing different types of work on different parts, and the ability to make "perfect" parts every time. Then there is the versatility; the same machines can perform many different operations, in many different ways, on many different kinds of material. Finally, there's the ease with which a whole line of sheet metal CNC machines can be integrated into an automated production system.
