This step is called post processing there are different post processors available. Export the job with a g-code, matching to your machine.These Path objects use internal FreeCAD G-Code dialect, independent of the CNC machine. Tools are selected as required by the Job Operations.This contains all the information required to generate the necessary G-Code to process the Job on a CNC mill: there is Stock material, the mill has a certain set of tools and it follows certain commands controlling speed and movements (usually G-Code). A 3D model is the base object, typically created using one or more of the Part Design, Part or Draft Workbenches.The FreeCAD Path Workbench workflow creates these machine instructions as follows: Typically, instructions are a G-Code dialect. These produce real-world 3D objects on CNC machines such as mills, lathes, lasercutters, or similar. The Path workbench is used to produce machine instructions for CNC machines from a FreeCAD 3D model. FreeCAD - Path workbench - About FreeCAD
