Spur gears are the simplest and most commonly used gears in mechanical systems, transmitting motion efficiently between parallel shafts. Fabricating spur gears on a milling machine requires precision to achieve accurate tooth profiles and ensure smooth operation.
        The process starts with selecting the appropriate gear blank material and preparing it to the required dimensions. The key parameters, including the module, number of teeth, pitch circle diameter, and pressure angle, are determined before machining.
        A milling machine equipped with a dividing head and an indexing mechanism is used for gear cutting. A gear cutter, chosen according to the module and tooth profile, is mounted on the milling arbor. The dividing head ensures accurate spacing between teeth by rotating the gear blank at precise intervals. The milling cutter is fed into the blank, cutting each tooth sequentially.
        Once all the teeth are cut, the gear is inspected for dimensional accuracy. Secondary processes like deburring, heat treatment, and grinding may be performed to enhance durability and smooth operation.
        Spur gears manufactured using a milling machine are widely used in automotive, industrial, and mechanical applications due to their efficiency, ease of fabrication, and reliability in power transmission systems.
