The story ends at the machine control panel. Before cutting expensive metal, the machinist performs a "Dry Run" or a simulation. If the downloaded post processor was successful, the machine follows the exact lines intended in the software. If not, the "post" is edited further until the G-code is flawless.

Never risk a $100,000 CNC machine to save $500 on a proper post processor. If not, the "post" is edited further until
When you generate a toolpath in SolidCAM, the software calculates the geometry of the cut in a generic, mathematical format. It knows where the tool tip is in 3D space, how fast it should spin, and how fast it should move. However, your CNC machine (whether it’s a Haas, Mazak, Fanuc, Siemens, or Heidenhain controller) does not understand this abstract geometry. It only understands G-code (and M-code).
