In a production environment, "dry runs" (running the machine without cutting material) eat into profitability. Simulation allows the programmer to prove out the code offline at a desk, leaving the CNC machine free to run paying jobs.
If you are a student or hobbyist, follow these steps to begin using a FANUC simulator: fanuc cnc simulator
FANUC controls are powerful, utilizing specific cycles like G70-G76 for turning or advanced canned cycles for milling. Simulators ensure that these cycles are called correctly, with proper feed rates and spindle speeds, verifying the logic of the program before it reaches the shop floor. In a production environment, "dry runs" (running the
