The Best CAD & CAM Software for CNC

CAD (Computer Aided Design) and CAM (Computer Aided Manufacturing) are critical software components of modern CNC (Computer Numerical Control) machining. Most modern machine shops make extensive use of CAD and CAM software because the vast majority of manual machines have been replaced by CNC versions.

If CAD and CAM terminology has you confused, you aren’t alone. Choosing the correct combination of CAD and CAM programs is challenging. This article describes the difference between CAD and CAM and provides a list of the most popular 2023 professional CAD/CAM packages and some free alternatives.
CAD refers to any software that can be used to create 3D models and technical 2D drawings of mechanical components. It’s also critical for the development of complex machine assemblies.
CAD is especially important for designing parts that need to be CNC machined, because machinists must input 3D model data into every CNC device so the machine knows what shape to manufacture. Also, technical drawings are usually developed by designers to indicate the tolerances of all critical features. In some cases, tolerances are indicated directly on the 3D model without the need for drawings — a practice known as MBD (Model Based Definition).
What Is CAM Software?
CAM is the software used by CNC machinists that converts the output from a CAD package — usually a 3D model — into a set of instructions for the CNC machine. These instructions are collectively called G-code.
The G-code includes information about the cutting tools to use for specific features, the cutter’s rotational and translational speeds (also known as speeds and feeds), and the path the cutting head should follow.
Professional (Paid) CAD/CAM
Most professional CAD systems are designed to be integrated with built-in CAM tools to make the transition from CAD to CAM as seamless as possible. However, CAM functionality often does not come with the base software and must be purchased separately. These professional CAD systems do more than just 3D modeling; they’re full-fledged engineering tools.

SOLIDWORKS®
SOLIDWORKS® is CAD software developed by Dassault Systemes. It is an engineering tool that offers all the basic and advanced 3D modeling and 2D drafting features, plus additional functionality like finite element analysis, mechanism simulation, and product rendering. In terms of its use for CNC machining, Solidworks® 3D models can be exported to any CAM package. Solidworks® also supports model-based definition, and compatible CAM software can be purchased at an additional cost.

Inventor®
Inventor® is Autodesk’s product that competes with Solidworks® — it’s comparable in terms of both basic and advanced features. Autodesk Inventor® is especially useful for machine design as it has a large library of standard components. Another advantage of Inventor® is its tight integration with Autodesk’s other engineering programs like Autocad. However, Inventor® has a steeper learning curve than Solidworks®. It also has a standalone CAM package that integrates seamlessly with the program, but must be purchased separately.

Fusion 360®
Fusion 360® is another 3D CAD software package developed by Autodesk. It was built as an all-encompassing engineering tool that covers the entire development cycle — from initial product design through evaluation stages and finishing with advanced CAM capabilities. It gives designers powerful simulation options that can test parts before finalizing designs. The seamless integration between CAD and CAM in Fusion 360® is one of its key features, and it’s one of the most intuitive CAD/CAM software options available. However, some of the advanced CAM features in Fusion 360® are only available for an additional fee.
