The present paper faces this problem by developing a special cycle that can be used on both types of machines. A code for this cycles is designed to read the part program of any product and if detects the code nominated for this cycle (G77) which indicates that a gear needs to be cut, it develops the geometrical statements of the gear profile and the motion statements. It follows by writing the full code of the cycle. The validity of the designed model was verified on a CNC simulator.enUniversity for CNCCAMMilling fixed cyclesManufacturing of spur gearBook chapterhttps://doi.org/10.4028/www.scientific.net/AMM.598.539
