Generally, computer-aided manufacturing software is used to create toolpaths. These aptly named operations define the path the cutting tool will take while removing or adding material. Specific parameters like cutting speed, spindle speed, type of motion, stepover, stepdown, and more are defined in the CAM software to fit the user’s specific application which the computer uses to generate the actual toolpath. Then the post processor translates the toolpath data into NC code that the machine can understand.

CAM software has several advantages over handwritten code or conversational (at the control) programming. First, complex toolpaths that would be impossible to write by hand can be created using CAM software. This includes complex tool motion found in high efficiency roughing toolpaths that leverage high computation algorithms or complex tool motion created from complex part geometry. CAM software like Fusion 360 is associative to the CAD model, so changes to the model automatically update the toolpath, saving time and reducing rework. CAM also allows programs to be created while a job is running on the machine, increasing overall productivity.

Yes, Fusion 360 can generate G-code for many CNC machines thanks to its large library of post processors. G-code is a language that many CNC machines use to operate, and how programmers and operators feed instructions to the machine. While it may seem antiquated, generating G-code is an important part of the programming workflow for the large majority of machinists today.

Yes, Fusion 360 includes a full suite of CAM software to program a variety of CNC machines. Fusion 360 manufacturing has a modern interface and helpful tips built in to make programming easy to learn and CAM easy to use. It’s a great low-cost option to start automating your machining and programming processes.
