SolidWorks® is one of the leading professional CAD packages. It offers various levels of add-ons from CAMWorks, which operates within itself. CAMWorks has a great reputation for CNC router and milling applications. It’s easy to call up the specifications for the machine being programmed, create toolpaths, and automatically update the toolpaths when model changes are made. SolidWorks licenses are expensive, though. They cost thousands of dollars per license. The student version, however, is very low cost for those properly accredited by an institution.

8. eCam

eCAM is an integrated CAD/CAM program with relatively simple CAD tools and good CAM tools.  It can drive CNC mills, routers, and lathes well. The CAD system, however, is limited to basic profiles and simple edits of imported data. eCam is well-liked for its easy generation of toolpaths through conversational programming. A simultaneous split-screen view of the conversational toolpath programming and the resulting G-code accommodates all skill levels of programmers and enhances the rate of learning. eCAM costs $180 for basic milling capabilities and $420 for the full professional mill/lathe package.

9. GRBL

GRBL is a free CAM software developed to enable Arduino boards to be used to control CNC machines. It has an extensive user community. GRBL has been adopted as the native controller software by several machine manufacturers in the hobbyist sector.

24. OpenCNCPilot

OpenCNC Pilot is free firmware specializing in pure CNC machine control. One of the unique features of OpenCNCPilot is its ability to use the CNC machine's position sensors to define the flatness of the section of the raw material that will be engraved to make the current part. The program adjusts the toolpath to compensate for the warpage of the feedstock, resulting in a product with the expected feature sizes and depths. OpenCNCPilot is Windows-based.

25. TurboCNC

TurboCNC is a DOS program. While its GUI is a bit primitive and its approach is archaic,  TurboCNC includes: a code editor, 8-axis common motion with integrated hysteresis compensation, parametric programming, multi-axis threading, and more. Priced at $60, you get the source code and developer support.

What is CNC Software?

The primary purpose of CNC software is to provide instructions to a CNC machine on how to cut a finished part out of a piece of raw material. It may also offer capabilities upstream of the actual machining stage: modeling of designs, creation, and verification of toolpaths, generation of G-code, and finally, machine control.

What Does CNC Software Do?

CNC software controls the CNC machine by generating the instructions to do so. These are often limited tools and they are best used for small edits, rather than for building complex parts and assemblies. The encoding tools turn a completed design into G-code. The simulation tools allow checking of toolpath - avoiding miscuts and in-motion crashes into parts  or machines. Finally, the machine controllers take your validated G-code and drive the machine to deliver the part you have designed.

What Are the Factors to Consider When Selecting CNC Software?

One factor to consider when selecting CNC software is the technical level of the user. Beginners should choose simpler tools, moving to more complex CNC software programs after mastering the basics. Another factor to consider is price. It’s a good idea to try the free version of a program before committing to a purchase. Finally, consider the complexity of the design. Make sure that the CNC machining software you select is capable of all the operations required to create the part.

What Are the Best CNC Software Choices for Beginners?

The best CNC software choice for beginners is Aspire. It is easy to learn, works well, and has enough features to satisfy new users' needs for some time before they feel the need for additional tools and capabilities. 

Is CNC Software Required for a CNC Machine?

Yes, CNC software is required for a CNC machine. To perform any manufacturing task, a CNC machine must receive instructions in a language it can understand, to tell it what to do next. CNC software can improve upon manually controlled machining processes in many ways: finding the optimal tool path, communicating with the machine tools, integrating feedback from sensor probes on the machine to make sure the path is being followed, and precise and complex motion control.
