2. Program Structure

A CNC program consists of a sequence of blocks. Each block contains specific instructions. fanuc series oi-tf plus programming manual

Must-Know Turning G-Codes from the Manual:

• G50 (Coordinate System/ Max Spindle Speed): The manual dedicates a full section to why you set G50 S2000 before G96—it caps the RPM to prevent centrifugal disasters.
• G70 (Finishing Cycle): Use this after roughing with G71. The manual stresses that G70 follows the exact profile defined by your P/Q blocks.
• G71 (Stock Removal in Turning): The workhorse. The manual details Type I (monotonous X) vs. Type II (non-monotonous X) roughing. Pro tip: The manual warns that forgetting a U (finish allowance) on the first block is the #1 cause of scrap parts.
• G72 (Face Roughing): Ideal for large diameter, short-length parts. The manual provides flowcharts to differentiate G71 vs. G72.
• G76 (Threading Cycle): The 0i-TF Plus manual shines here. It explains multi-block threading parameters: P (finish allowance + chamfer angle + thread angle), Q (minimum cutting depth), and R (finish allowance). No more guessing.
