CAM (Computer Aided Manufacturing) is an operation in manufacturing used to make a part program from a design file.
It is performed by certain software programs developed to analyze the geometric data of a design and convert it to G-code.
This article lists and reviews the best CAM software programs to work with CNC machines.

SOLIDWORKS CAM is an add-on software that works in unison with SOLIDWORKS CAD, the main software.
To access the features of SOLIDWORKS CAM, you must have SOLIDWORKS CAD pre-installed on your computer.
It only works on PCs running on 64-bit Windows OS. It's a memory-intensive software that requires 16 GB of RAM and at least a 3.3 GHz processor.
SOLIDWORKS is best suited for professionals, allowing you to make codes for 2D and 3D designs.
It is paid software, but the developers provide a free license for startups and entrepreneurs. To access the free license, you can contact Dassault Systems.
They offer good support to the customers. You can download learning resources, training materials, and tutorials from the customer portal.
|EstlCAM||Windows||No||Free (unlimited trial)|
EstlCAM is a simple beginner-friendly CAM software. You can use the software for free as an unlimited trial or buy a full license for around $60.
Unlike other software, it does not require a powerful computer but is only supported for Windows computers.
To make it compatible with different versions of Windows OS, the developer has made separate drivers.
The software accepts many different file formats and is compatible with 3D designs. Some of the formats it accepts are the following.
EstlCAM has a simple workflow. Once you import the design file, it'll ask you to set the tool details, based on which the software will automatically generate a toolpath.
For toolpath files like G-code and NC, EstlCAM has an integrated CNC controller interface to send the code to the CNC machine.
EstlCAM also allows you to configure it with popular CNC control software like Mach 3 and Mach 4, LinuxCNC, PlanetCNC, Carbide Motion, and firmware like Marlin and GRBL.
If you are a hobbyist, then the free version will do the job for you, but if you work with CNC machines regularly, I recommend getting an Estlcam License as it provides toolpaths faster.
Christian Knull (the developer) uploads many educational videos of EstlCAM software on YouTube. You can refer to those to visually learn the software.
You can run EstlCAM software offline, and it doesn't need internet access to operate. You can activate it online or use an offline license key for initial authentication.
Here's a more detailed review of EstlCAM software.
As it's clear from its name, OpenBuilds CAM is a free CAM software from OpenBuilds. They are known for their open-source software and hardware products.
OpenBuilds CAM runs on internet browsers. Hence it is OS-independent and compatible with most devices.
Unfortunately, you'll need to have access to the internet to use the software.
The software has simple controls that are well spread out on the user interface. It gives out part programs in G-code format.
You can learn the software easily from its community through forums, YouTube videos, and using the quick start documentation on its website.
Once you open the software, it'll ask you to configure some options. You must set your machine, controller, and tool configuration for the software to work.
They have some common values preloaded on the software for easy access, but you can also enter your custom values.
OpenBuilds CAM can also work with their control software, OpenBuilds CONTROL.
The control software is not browser-based. It works on computers running Windows, Mac, and Linux OS.
|CamBam software||Windows||Yes||Free & Paid|
CamBam is a CAM software for Windows PCs. It is a good CAM solution for hobbyists and businesses.
The CAD-compatible software allows you to make simple designs using lines and basic shapes, but cannot be considered a replacement for full-fledged CAD software.
If you import and make changes to the design file, CamBam automatically optimizes toolpaths to match the initial design.
The software is compatible with 2D, 2.5D, and 3D designs. Some of the supported file types include DXF, STL, RAW, 3DS, etc.
CamBam also supports 4th-axis wrapping, which is helpful when working on cylindrical workpieces.
The plugin support is a helpful feature. It allows you to further enhance the capabilities of CamBam software with additional pieces of software.
CamBam provides a 40 sessions free trial where you can try and test all the features of the software.
After crossing the trial sessions, you'll need to purchase the full version of the software to access all the features. Else you'll have to use it for free with limited features.

MeshCAM has a simple user interface. It allows you to easily navigate and work with different parameters.
It is compatible with STL and DXF file formats which most CAD software supports. MeshCAM is known to process large design files of up to 500 MB.
You can also import 2D files like JPEG into MeshCAM and extract them into 3D designs to make toolpaths.
The post-processors loaded onto the software allows you to get a G-code that works with most CNC machines.
If you can't find a post-processor built for your machine, the developers allow you to raise a request to make one that works for your machine.
MeshCAM uses different settings on the same design for generating toolpath for different operations.
You can run the software on computers running on Windows or Mac OS. Also, it requires at least 4GB of RAM to run smoothly.
MeshCAM doesn't need an active internet connection to work. It only requires internet access for the initial installation and license authentication.
If you are looking for more advanced software, check out the Pro version of MeshCAM. It offers extra features like toolpath simulation, pocket toolpath, contour toolpath, etc.
To check the generated toolpath's simulation, you can use any free CNC simulation software and save some money.
Here's a more detailed review of MeshCAM software.
The controllers onboard CNC machines cannot analyze the design files. It needs to be converted to a language that the controllers on these CNC machines can understand.
A CAM software program is the most efficient way to convert a design file to code that's ready to be sent to a CNC machine.
Frequently Asked Questions
What are CAD, CAM, and control in CNC?
CAD, CAM, and control in CNC are different operations performed sequentially to make something using a CNC machine. CAD, short for Computer-Aided Design, is the process of making designs on a computer. CAM, short for Computer-Aided Manufacturing, is the process of converting the design to code that CNC machines can understand. Control is the process of setting the optimal machining parameters to execute the machining process. All these operations are done using their dedicated software.
Which language is used in CNC programming?
In CNC, G-code programming language is used. It is an alphanumerical language that CNC controllers can read, and it has details about the cutter location, speeds, tools, RPM, etc. Generally, CAM software automatically generates these program codes, but they can also be programmed manually.
What are some of the best CNC software?
Some of the best CNC software are Easel, Carbide Create, VCarve Pro, Autodesk Fusion 360, SOLIDWORKS, Inkscape, AutoCAD, DeskProto, MeshCAM, CamBam, Estlcam, Openbuilds CAM, Mach 3 or 4, GRBL Candle, etc.
