CAD, CAM and CNC Machining Softwares in 2023(Free & Paid)

A Computer Numerical Control (CNC) software enables to create programs to run a machine tool. Each part of the machine requires its own CNC program. The primary CNC programming language is G-Code. Alternate to G-Code, there are Heidenhain and Mazak also in use. 

G- Code is programmed in such a way that it controls the movement of a machine by adjusting the position of x, y, and z-axis. It is capable of controlling the speed of rotation and rate of the movement.

In CNC machining, the commonly used file formats are STEP and IGES. These formats can be used across platforms.

From design to manufacturing stage, a CNC machine uses three different kinds of softwares namely, CAD, CAM and CNC controller software. You first need a design in a vector file, unless you already have G-Code. This design is converted to G-Code using CAM program.  

G- Code is used to communicate with the CNC machines and enables the machine to move in the desired pattern. 

Since we know that a lot of our readers are newbies who are looking for the woodworking tools and recommendations.

We have curated the article from our own experience and research which will enable you to find the software for CNC machine but also multiple different options which are both paid and free. 

Step 1: Create a vector file (DXF) using a Computer-Aided Design (CAD) software.

To get started with the design stage, you require a vector file(A vector file has coordinates for the tools to move in different axis). You can create designs and vectors using CAD software where CAD stands for Computer Aided Design.

The most common vector file format is DXF. This is the file extension for a graphic image and enables data interoperability between CAD and other programs. You can open DXF files in Mac and Windows OS.

Bonus: GrabCAD has an interesting feature called Workbench that allows user to collaborate on a CAD design with others. It is a platform where people from all walks of designing like woodworkers, architects and professional designers can work together and download a ton of different CAD files. Acquired by Stsratasys, they now have two products: GrabCAD Workbench and GrabCAD Print 

Step 2: Convert the vector file to G-Code using Computer-Aided Manufacturing (CAM) software.

From CAD program, the vector file is converted to G -Code. This is the language used in CNC machining. This process is done with the help of CAM software which stands for Computer-Aided Manufacturing. CAM software can generate G- Code from a CAD design or an image. This software uses the models and assemblies created in CAD software to generate toolpaths that drive machine tools to turn designs into physical parts.

It can eradicate the gap between design and manufacturing by the appropriate realization of drawings, designs, and models and provide the anticipated output. Eventually, this expands the scope of production and manufacturing.Some CAM programs can directly edit the CAD file and generate corresponding G-Codes using CAD Editing Programs. There are G-Code editing programs that can be used to convert G Code to Conversation CNC or to simulate the G -Code itself.G-Code is one of the most popular and widely used programming languages. A G-Code is used to instruct and control automated tools. This also provides the direction in which the machine should move.

It directs the machine on the speed and depth of the movement. There are many types of G -Code files, the most popular G-code file types are .CNC,.NC and.TAP.For simple requirements such as circles and lines, you can easily create G-Code manually. But it is even easier to produce the same with the help of CAM software. In the latest CNC Machining system, the 2D drawings are no longer required for manufactures a machine. The current machining systems can directly interpret the part geometry from 3D CAD files. Let’s have a look at the CAM softwares. Once a CAD model is imported into CAM, the software starts making the model for machining.

Step 3: Use CNC software to process the G-Code to run the machine in the desired manner.

The G-Code from CAM software is processed by CNC software. The main task of CNC software is now to input G-Code and deliver the right electrical outputs to make the CNC router work. There are two types of CNC control software. One control software built into your machine and other is PC-based software.If you are using a CNC machine such as HAAS Vertical Machining, you would require a complete solution complete hardware and software solution that is built into the machine. In this, you can transfer G-code directly to the machine.

CNC for Woodworking

Woodworking is the most widely used application of a CNC router since it offers a lot of benefits and flexibility when working with wood than with any other material. Newbies or hobby woodworkers often start work with single CNC routers to create DIY stuff and projects.

For such users, we have reviewed the woodworking software since there are a lot of things to consider when getting your first woodworking design software that will allow the functioning of tools and elements that you want.

3 woodworking software for your cnc router:


What is G-code and M-Code?

Both G-code and M-code carry different information. A G-Code (Geometry) is related to the placement of the hardware relative to the workpiece like cutting tasks and determining units. M-code (Miscellaneous) is about different functions and configurations like the On/off commands, speed, tool changes and coolant. 

Is CNC Machining hard to learn?

A CNC machining is not hard to learn. Though if you new to CNC routers/machines then you can find it slightly difficult to get accustomed to the number of different functions in the NC machines. But once you get the hook of it, everything will be easy with time. It’s just like learning a new piece of art. 


The major benefits of using CNC machines in each industry are:

  • Better machining accuracy
  • Enables to perform complex tasks easily
  • Provides flexibility
  • Maintenance cost is very less unless you do heavy tasks
  • It retains its design and the labor is less.
  • Reduces the time to perform a job drastically.
  • They could run for the entire day.
  • No possibility of human error and manual intervention.

By using a CNC machine software, you can take complete control of all the processes involved in the manufacturing and monitor end to end process. The production process of a CNC router reduces the number of steps required to make a part.

The entire fabrication process is automated and by choosing the right CNC software at each step, you improve the efficiency. 

The same components can be reproduced and replicated as many times as required without compromising the quality. A single person can supervise multiple CNC routers with ease if he gets accustomed with the cnc software.

There is no need to make a prototype model. You can directly simulate the requirements in the software.

There are a few limitations associated with CNC. Based on the age and sophistication, CNC machines have limited capabilities in control and drive systems.

Most CNC control softwares only interpret straight line movements and circular arcs. In many cases, the arcs are restricted to the principal XYZ planes. 

The demand for the CNC router with immense capabilities is still on the rise. Though it has many limitations, its advantages outnumber them. Hence, CNC is here to stay long and enhance its capabilities now and then.

  1. Hello! I am a beginner with a style cnc router 6090. I am doing memorial stones and would like to know what is the best software out there for a beginner?
    Thank you

        • Hi Stephen

          You’re correct. The software has been discontinued by Autodesk since 2018, however some of our users were still able to download and use it from opensource resource.

          But we will now add a line next to it with some of the alternatives to ArtCam. Let me know if you have any recommendations for us.

          • Carveco bought the rights to Artcam. I converted to it when Autodesk dumped Artcam. It even reads all Artcam files.

  2. Hello –
    I am in the process of purchasing a CNC router that engraves on stone and the images are quite large. The apparatus is special as it is the framework without a platform and it is placed on a railing system that lies over the stone and engraves. Because the images are quite large, sometimes larger than the apparatus, I am looking for a software that allows you to pick up the apparatus and move it while keeping place of where the image has stopped and will start up again to finish the engraving. Can you recommend a software that will accomplish that?

  3. Hello
    Thank you for this wonderful article!
    I am in the market to buy CNC machine to produce custom furniture with lots of carvings and engrave in the wood (including custom design for the fabric) , if you were me what machine would you buy and which softwares would have been your choice for CAM and CAD ?

    • Hi Anna

      Thanks for dropping by, Sure so if I was looking for a CNC machine that can make custom furniture which means there will be a lots of operations that will involve wood as a material. I will recommend you a CNC machine like Genmitsu CNC or the Yofuly CNC machine, else if you could let us know your budget, I can recommend you better options. As far as the software is concerned, i will go for Autodesk CAD/CAM software due to the features and the easy UI.

      Feel free to ask more questions.


      • Hi friend, i have a cnc router what i brought from china and we don’t have the software for the machine, if you work in this area we need support, I would like to speak with you and reach an agreement to put this machine to work, since the company from which we bought the machine never supported us.

  4. Hey great article thank you for the excellent information.. I have a a 3018. I have upgraded the spindle mount and spindle from 200 to 500. I lost the CD for grbl for it. So I downloaded bCNC as I am running it on a Pi4 2gb. I’ve made designs in tinkercad and I want to send them to bCNC! Would you suggest I use Pycam as my cam sorfware. Or could I use easel? Any advice would be very appreciated. Thank you

  5. Thank you for this article, found it to be more informative than anything else i’ve looked at. But still at a bit of a loss on how to proceed.
    I’ve purchased a 3018 which is have Candle 1.0 software provided.
    I want to create simple text along with a basic imported image, which software would you go for to generate the appropriate g-code?

    Thank you

  6. Those looking for an inexpensive option for CAD/CAM CNC software should also check out ProNest LT Subscriptions. Monthly plans start at $29.99(USD) and includes unlimited tech support access & training!

  7. Hi

    Hope you are well. We are an architecture firm and we have recently purchased a 3 axis CNC machine. We use Revit and Autocad. What software would you recommend for cutting timber for building architecture models?


  8. I need to urgently replace an old unrepairable ISEL Controller for a 3 axis cnc machine with stepper motors. I have been using Autocad for the last 25 years and the old software converts HPGL plot files to machine language very simply. Everything now points to G code which seems cumbersome in comparison and which I have no knowledge of. Any suggestions and advice will be most welcome.

  9. Aloha! I’ve briefly worked with a Maverick CNC at a previous job (I was much more familiar with laser cutting) I’d like to try my hand at some small-scale modeling at home. I have CorelDRAW and AdobeSuite, and am enjoying my Glowforge. Is there a small tabletop or desktop milling unit/software you would recommend for 3D carving? (I had my hands full with laser orders and just TOUCHED Aspire as a program here n there)

  10. We have an Italian CNC machine called Rover A and operating system is biesseworks. We normally use either cabinet vision or alphacam to do the geometrics. And we do all sorts of carpentry works, such as doors and cabinets doors and a variety of different designs on wood.

    What I’m looking for is someone who has the programs and can design the work and do the geometrics for me to be able to just put on the machine and get it working.

    Thank you very much!
    I really appreciate your help!

  11. Thank you for the wonderful article. I am just starting down the process of setting up a CNC routing for wood and soft metal projects. I have not made any purchases and want to know if there are spec variations or recommended CAD, CAM and CNC machining software specifically for use with a Mac.

  12. Thank you for the article! I really learned a lot from it.
    I am new to CNC Machining and looking to learning how to design different products like shoe soles, plastic bottles, e.t.c. Can you please advice on the best software to use and the best CNC machine which can be used to produce the moulds of the designed products. I was looking at fusion 360, but I am not so sure.

    Thank you!

  13. Anyone ever use InventorCam to generate G code? How does it compare with Mastercam? I work with Grade 9-12 schools and we just installed Fusion and Inventor in our Windows Virtual Desktop environment. Rather than transferring to Mastercam, I’m wondering if it’s easier to stay in InventorCam. Anything I’d be missing terribly by doing this?

  14. Thanks a lot Sir, for the fantastic info. Very well explained about different software for CNC usage.

    Highly appreciated
    Sam Parasuraman

  15. Hello I was wondering if anyone mows if one CBC will work with my Langmuir CBC plasma I tried fusion 360 and can’t even draw a Square box the program is to touchy for just flat work I am looking for a similar program thanks

  16. Thanks for sharing so many good options for CAD designs. It seems like it would be great to have talented workers to do this. I’m sure it takes a lot of work to learn this software.
