Generate the G-code file, also known as post-processing, and save it.Run a simulation to verify that the operation plan and toolpath selected by the software align with your machine shop practices.Next, prompt the software to generate a toolpath.Create a manufacturing sequence, also known in SolidWorks as an operation plan.Next, select the CNC machine, cutter, and coordinate system.Fusion 360, for instance, requires you to change the workspace from ‘Design’ to ‘Manufacturing.’ On the other hand, in SolidWorks, you have to open the SolidWorks CAM add-in. With these programs, all you have to do to use the built-in CAM capabilities is enter the manufacturing mode. However, software applications such as SolidWorks and Fusion 360 combine CAD and CAM capabilities they are known as CAD/CAM software. Next, the model is imported into CAM software, a program that automates the manufacturing process.The process begins with creating a 2D drawing or 3D model of a part using CAD software like AutoCAD, SketchUp, and more. The CAD/CAM approach is currently the most popular method of creating code for CNC machines compared to other approaches. How CAD and CAM are Applied in CNC Machining As technology advanced, in came CAD and CAM software, substantially improving the experience. However, it was disadvantageous because it used English-like commands to define geometry rather than graphical elements, which were more convenient. This approach was advantageous because it reduced the burden of knowing how to code extensively. Then, the computer compiled these statements, converting them to machine code. Rather, they simply wrote statements that followed an English-like syntax. Operators no longer had to write machine code – G-Code and M-code. This approach was more simplistic and saved a lot of time.
