CNC Basic Guides & Tutorials for Beginners

The Mechanic Doctor – Resources for Amateur and Pro Auto Mechanics

CNC machining has been around for decades, and it’s only become more popular as the population of manufacturing companies grows. It is a type of machine tool that is used to create computerized numerical control (or CNC) parts with fast, accurate cuts. Most CNC machines are controlled by computers and work in conjunction with CAD design software to make sure they cut precisely what you want them to. This guide will cover basic information about how this process works so that you can get started on your own project!

This article has been created by ensuring the best quality information about CNC machining to make it helpful for beginners. Experts from CNC Now, a well-known CNC service company in China, helped us to ensure the quality of this article.

Concept of CNC machining

CNC machining has been around for decades, and it’s only become more popular as the population of manufacturing companies grows. It is a type of machine tool that is used to create computerized numerical control (or CNC) parts with fast, accurate cuts. Most CNC machines are controlled by computers and work in conjunction with CAD design software to make sure they cut precisely what you want them to. This guide will cover basic information about how this process works so that you can get started on your own project!

The CNC Software Stack

There are three main types of software packages often associated with the creation of CNC programs: CAM/CAM editing program, post-processor or G-code interpreter, part programming environment – these allow you to create and edit CNC programs, interpret the G-code created by CAM software, or use a part programming environment for creating CNC machine steps.

A wide range of CAD/CAM packages is used in conjunction with post-processing to make sure that all your hard work on the design doesn’t go to waste once it’s cut out from the material you’ve chosen. Some popular CAM programs include Fusion 360 (Autodesk), Mastercam X (Mastercam), Carbide Create (Carbide), and Vectric CutPro(Vectric).

Depending on what kind of CNC machine you have, these different types may be more applicable than others! For instance, if you don’t want to buy an expensive pro CNC machine, you might be better off with a DIY CNC machine.

The G-Code created by CAM software is then used to create the actual set of instructions for the material as it’s being cut out from your stock piece of aluminum or other metals. It takes into account everything that would make up the workpiece – size, height and depth of cuts, specific angles on corners, etc. This information is saved onto a file that can be read by pretty much any commercial post-processing program in order to see what will happen when it meets its destiny in the cutter’s head!

CAM programs have also been developed for those who want to use their own CAD/CAM packages but still need something more than an ordinary part programming environment.

CAM Software

CAM software is a program that you use to generate the steps for your machine to cut from the raw material. It takes into account everything that would make up the workpiece – size, height and depth of cuts, specific angles on corners, etc. This information is saved onto a file that can be read by pretty much any commercial post-processing program in order to see what will happen when it meets its destiny in the cutter’s head!

CAM programs have also been developed for those who want to use their own CAD/CAM packages but still need something more than an ordinary part programming environment.

In this guide, we are going to go over some basic concepts as well as how these programs work so anyone with little to no experience can become more confident in using them.

We will also be covering the different types of machines available and what to consider when purchasing or building your own, as well as some tips on how you might go about learning CNC programming if that’s something you’re interested in!

There are many other ways to get started with these programs so it is worth doing a bit of research before choosing one – not only for yourself but because every company has its strengths and weaknesses which may suit you better than others.

For example, if accuracy is really important then a machine with linear rails would be best whereas those who need speed over everything else would want to look into direct drive systems like brushless motors embedded right onto the gantry.

As you can see, there are a lot of considerations when it comes to picking out the perfect CNC machine for your needs.

Whether or not you want to build one yourself from scratch or buy an off-the-shelf model that has everything already included, we have tried and tested all sorts so make sure to take advantage of our advice!

Building or purchasing a CNC machine; what should you do?

When you’re looking to buy a CNC machine, it’s important to consider the purpose of using it.

If speed is your number one priority then an Acrylic or MDF model that uses linear rails would be best whereas those who need precision and quality over everything else should look into direct drive systems like brushless motors embedded right onto the gantry.

Which kind of CNC machine do I want?

The type of machine will depend on a variety of factors including what you want out from it; whether this might just be for hobby use or if you are interested in getting serious with CNC machining.

A hobbyist CNC machinist is typically best suited to a DIY machine with an acrylic or MDF work surface.

The other end of the spectrum would be those who are interested in getting serious and building their own pro-CNC machines from scratch, for these people it’s worth investing in a direct drive system like brushless motors embedded right onto the gantry.

If you have no idea what kind of machine you want then we recommend taking a look at our buyer’s guide below!

What should I consider when buying my first CNC Machine?

There are certain things that need to be taken into account before purchasing your first CNC machine: The size and scale needed; whether this will act as your sole machine for production or not; whether you want to use a CNC router, mill-drill, laser cutter and so on.

The best thing is to take the time to research what’s out there in terms of machines, look at all the benefits they offer then decide which one meets your requirements! It can also help if you ask someone who has experience with these kinds of products for advice. With some guidance from those already knowledgeable about such machinery, it might just save you from making an expensive mistake too.

Which one should I purchase? A new CNC machine or an old one?

There are a couple of factors to consider when deciding this.

The first thing is whether you have the money for it in your budget. If not, then an old one could be worth considering looking at but if you can afford new machinery and want something that will last longer without going wrong as much (all machines do break down eventually!) then go ahead and get a new or nearly-new machine.

It also depends on what type of CNC machining work you’re doing – there are certain types where older models might suit perfectly well while others need newer equipment so think carefully about which application each machine would suit best before settling on anything!

The Final Words

As with all things in life, it is important to have a good foundation and understanding of what you are doing before going ahead. This means taking the time to learn about the concepts that underpin this technology so you can use your machine well. Once you’ve learned some of these fundamentals then go out there and find yourself a bargain!
