There are many things we already know about CNC machines and that’s why many of us consider them an essential part that has influenced almost every form of manufacturing process in one way or another. However, there are certain peculiarities that are yet to be thoroughly discovered and presented.
Here are some basic aspects and tips for CNC machines:
- CNC machines are programmed with a design that can be manufactured numerous times.
- CNC machines can be used non-stop, 24 hours a day, 365 days a year. Only when it comes to maintenance do they ever need to be turned off.
- CNC machines can be modernized and improved by updating the software utilized for the machine’s motion.
- In contrast to manual lathes/milling machines that require skilled engineers, CNC machines can be operated even by people who aren’t as trained/skilled.
- You can get CNC training similar to a computer game that will help you learn and practice how to use CNC machines.
Less known fact about CNC machines is that apart from wood and plastic, they can also be used for cutting aluminum. Here are some useful tips that mustn’t be overlooked if you do decide to take advantage of CNC machining aluminum.
- CNC Routers have the ability to cut aluminum, but they aren’t the ideal tool when it comes to wing spars. Using CNC machining aluminum can also be a little bit more time-consuming.
- With aluminum, only 3 or fewer flutes should be used due to the fact that aluminum produces rather large chips. If you use fewer flutes, there will be more room between the cutting edges, whereas with too many flutes you can end up with a broken cutter.
- The rigidity of a given machine cannot be easily measured. However, spindle power can be used as a proxy. Spindle power is the power that pushes against the workpiece during the process of cutting and the rigidity must fight against it. G-Wizard is able to calculate a “de-rated” spindle power that is in accordance with the work envelope and weight of your machine, thus creating a spindle power that is convenient for that level of rigidity.
CNC machining aluminum is totally doable; you just need to meticulously match the capabilities of the machine to the speeds requirements of the material through careful selection of cutting and tooling parameters. A good G-Wizard can really come in handy for that. And don’t forget the need for lubrication and keeping track of chips piling up and you’ll be all set.
