CNC machines are the backbone of modern manufacturing. Whether you are using a new CNC or buying a used CNC machine, you can get any precise manufacturing work done as per your business requirements. But no matter which brand of CNC you are using or how many axes the machine has, one thing you need to be very careful about is what software is being employed in the CNC machine. The software can be the most important determinant of your machining experience, as it can decide how seamlessly you will be able to carry out the entire machining process. In this blog, we will talk about all the well-known software that is used in CNC machines, and you can choose one among them for the best machining experience. 

Understanding CNC software: The basics: 

CNC software is a digital tool that helps create, process, and deliver instructions, such as G-code or M-code, for CNC machines. You can use the most advanced CNC model or a 20 year old CNC machine; in both cases, you will need CNC software to generate toolpaths, make product designs, and control the machine’s movement. 

There are a total of 4 types of software that are used in a CNC machine: 

  1. CAD software: CAD refers to Computer Aided Design software, which is used to create 2D or 3D models of the products that you want to manufacture. 
  2. CAM software: CAM refers to Computer Aided Manufacturing software, which is used for converting CAD designs into machine-readable instructions, like the G-code, which further helps in guiding the movement of the CNC machine. 
  3. Control software: This interfaces with the CNC machine and gets the G-code, which helps in controlling the spindles, motors, and other parts. 
  4. Simulation software: This software helps in testing the machining process virtually to identify potential issues or errors before the main machining starts. 

CNC software selection criteria: 

Here are the things that you need to keep in mind while choosing which software is going to be best for you: 

  1. Check if the software is easy to use; avoid software with a high learning curve.  
  2. Check the support and ecosystems available with the software, see if the company provides enough support, and if there are enough tutorials available for it. 
  3. They check the costing structure, like the subscription fee for the software.
  4. Check if the software is flexible and can support any further integration with the machine. 
  5. Check the compatibility of the machine, especially for used CNC machines, as modern software versions may not be a good choice for old models of CNCs. 

List of the most popular software: 

So, let’s jump to answering the main question: What are the main CAD and CAM software that you can use in your CNC machine?

  1. Autodesk Fusion 360: Fusion 360 is a cloud-based CAD/CAM platform that integrates designs, manufacturing, and simulation in one package. This works with most of the CNC controllers via post processors.
    Advantages of Autodesk Fusion 360: It is mainly free for hobbyists and small shops, it is very powerful and has a lot of features, provides cloud storage, and has frequent updates for continuous improvement.
    Downsides: Some of the problems with Autodesk Fusion 360 are that some of their most handy features come only with the paid version, and it has so many features that you might feel overwhelmed as a newbie.
  2. MasterCam: Mastercam is one of the most popular CAM software programs that has been used and trusted by industry veterans for decades. It is well celebrated for its versatility across different works like turning, milling, and multi axis machining.
    Key features of Mastercam: some of the most important features of Mastercam are that it supports 2D to 5-axis machining, has an extensive library of machine specific post processors, and advanced simulation for collision detection. This is best for machining shops that need complex toolpath generation for their work.
    This CAM software is mostly compatible with different controllers like Fanuc, Siemens, and Heidenhain. Their pricing is pretty affordable, and a subscription model is also available.
  3. Solidworks+CAMWorks: Solidworks by Dassault Systèmes is one of the finest CAD software programs popular in the world of engineering and manufacturing. It is well celebrated for its complex assemblies and precise design. CAMworks, on the other hand, is a solidworks-integrated CAM solution that is known for its high-speed machining and iMachining technology.
    Advantages of using Solidworks or CAMWorks: some of the top benefits of using these software are that Solidworks has parametric modelling features which help in easy design modification, a large library of standard components for machine designs, and the iMachining feature of CAMWorks helps with faster cutting and longer tool life. They are compatible with most modern and old controllers.
  4. FreeCAD+Path workbench: FreeCAD is a free and open source CAD software, which is quite popular among hobbyists and small machining shops. It is customizable and supports both 2D and 3D design types. FreeCAD’s Path Workbench is an open source CAM module that will help you in generating G-code for your CNC machine.
    Features of FreeCAD and Path workbench: They help in parametric modelling for iterative design, modular architecture for adding CNC specific plugins, and they can help with basic 2D and 3D toolpath generation. The flexibility and zero cost feature of these CAD and CAM software make it more popular among small budget machining shops.

Here’s the list of some of the top control and simulation software for CNC machining: 

  1. Mach3/Mach4: Mach3 is one of the oldest control software in the CNC machining industry, and it’s well celebrated for its affordability and its compatibility with desktop CNC machines. It supports different operations like turning, milling, and plasma cutting, it has a customizable interface for user preference, and is compatible with parallel port and USB controllers. It can work with different legacy controllers. 
  2. LinuxCNC: LinuxCNC is a free, open source control software for CNC machines, which is also highly customizable, and runs on Linux systems. One of the key features of LinuxCNC is that it supports complex machine setups and multi axis machining. Other than that, they also have a real time monitoring feature which helps to minimize errors and also have other advanced features for experienced users. 
  3. G-Wizard editor: G-Wizard editor is a G-code editor and simulator that helps visualize toolpaths and detect errors. One of the finest features of this software is line by line G-code translation for easy debugging. The software is also affordable for small shops and works with most G-code formats. 
  4. NC viewer: NC viewer is a free web-based G-Code simulator that helps you visualize the toolpath without the need for any installation. The software is browser based for easy access, visualizes 2D and 3D toolpaths, and supports the common G-code format.
