About Precision CNC Machining: How It Works

precision cnc machining servicesPrecision CNC machining services are essential for dozens of industries. Everything from telecommunications and Fiber Optics to food manufacturing and aerospace technology relies, in some form, on precision CNC machining services.

Computer numerical control (CNC) machines have been providing modern precision services since World War II, becoming industry standard during the late 1960s. Today, since industrial sheet metal is the number one most common type of metal across the manufacturing sector, CNC machining is used much more frequently for sheet metal fabrication than in days gone by. But this type of machining has been providing precision tool automation for decades, and with recent developments in the computer industry, the term “precision machining” has taken on an entirely new meaning.

But how does the actual machining process work?

Computer aided machining now allows for the manufacturing of very precise, very necessary parts with the most precise specifications. This type of machining can produce all kinds of complex components with a degree of accuracy never before seen. Whether it’s lathes, routers, mills, grinders, or dozens of other tools and components, all of these can be controlled by CNC precision machining.

Today, 5 axis machining is similar to traditional CNC machining, but it uses CNC machines to move a workpiece along five different axes simultaneously. Because of the five axes, much higher levels of precision are able to be obtained and very small complex parts can be controlled. Though 5 axis machining involves highly advanced technology and increased accuracy, this process remains quite affordable.

Thanks to a stronger emphasis on precision and accuracy over the years, CNC machining can reach tolerances as low as 0.002 inches. No matter what industry you’re working in, you’re going to need State of the Art programming software, as well as highly accurate and highly capable tools, to ensure success. Proper CNC machining is necessary in all aspect of manufacturing and programming.

Plus, thanks to the Internet, it’s never been easier to share designs with precision CNC machining services, even if they’re on the opposite side of the world. Your specifications and designs can be easily downloaded and stored so that quality machine shops can produce your parts down to the thousandth of an inch.

There are so many careers that would be essentially obsolete if it wasn’t for precision CNC machining. Though the technology has rapidly improved over the last few decades, it looks like CNC machining isn’t going anywhere.

Sheet Metal Fabrication: 3 Aspects to Focus On

sheet metal fabricationSheet metal fabrication is an essential part of the manufacturing market. Dozens of industries are impacted by various sheet metal procedures and not just across the United States. In fact, by the year 2020 the international metal fabrication equipment market is expected to grow by nearly 7%.

Because of the importance of sheet metal fabrication, it’s good to know some of the best ways to manufacture these sheet metal parts. From 5 axis machining to 3D printing, there are all kinds of fabrication methods that require skilled and knowledgeable design workers. Here are some aspects of metal fabrication that you should know about.

Sheet thickness
The metal wall thickness is essential for each piece of sheet metal no matter what it’s being used for. Metal parts should maintain a uniform wall thickness throughout the entirety of the fabrication process, too. It should be relatively easy to maintain the same thickness throughout because the single sheet of metal is all you’ll be using.

Sheet metal brake bends
A sheet’s bends can make or break an entire product. Bends in the same plane should be manufactured to go in the same exact direction as the other bends to avoid the focus of the sheet being drastically shifted during fabrication. If the bends remain consistent, however, you’ll save money and time. A good rule of thumb for preventing sheet fracturing is to have the inside bend radius the same as the sheet’s thickness. In addition to bends, curls are just as important. Sheet holes should be located away from the curl and the curls’ outside radius should be at least twice the sheet’s thickness.

Sheet metal hems
Hems are folds to the edge of a part the result in rounded and safe edges. A sheet’s hems can be flat, tear-dropped, or open, but it all depends on the sheet’s thickness or overall radius. It’s not recommended to use flat hems, however, because they often lead to fractures.

5 Axis Machining 101: How It Works

5 axis machiningMetal fabrication is a complicated process that requires both experienced labor and high quality machinery. The major benefit of 5 axis machining is the ability to machine couples shapes in a single set-up, subsequently providing greater machining productivity and making the entire task more time efficient.

In simpler terms, a block of material is manipulated until the unnecessary bits have been removed and the target object is all that’s left. Hopefully this will help you better understand how 5 axis machining is used within the metal fabrication industry.

5 Axis CNC Machining — Computer numerical control (CNC) manufacturing uses a multiaxis machining software system to support the milling away of access material by either water jet cutting or laser cutting. With these precision CNC machining services, the amount of human labor is drastically reduced for each milling task, a more precise surface finish can be obtained, and much more complex parts can be manufactured.

A 5 axis CNC machine simultaneously moves a tool to perform a milling job and remove excess material from an object. However, 3 axis machining only moves a part in two directions while the tool moves up and down. The number of axes for multi axis machines can range from 2 to 9, with 5 being the most common.

The 5 Axes Configurations — A 5 axis machine’s specific configuration determines which rotational ages (of the three) it will utilize during a milling task. A common style of 5 axis machinery operates with an A-axis rotating about the X-axis and a C-axis rotating about the Z-axis. Consequently, a swivel-rotate-style axis machine operates with a B-axis rotating about the Y-axis and a C-axis rotating about the Z-axis.

Getting The Most Out of 5 Axis Machining — Since 5 axis capabilities are often under-utilized across various industries, it’s important to use high quality equipment and take excellent care of its maintenance needs.

“Some may have the machine but not understand it’s full capability, or they may not have the software that’s needed to create a cutting program that would utilize the machine’s full capabilities,” said Mike Finn, Mazak America’s industrial applications engineering manager. “When you’re doing high-speed 5-axis machining, the servo drives on the machine and the response time is very important to avoid shortcutting or overshooting when machining.”
