Gear Design: The first step is to design the internal gear with the desired specifications, including the helix angle of 50 degrees. This involves determining the size, number of teeth, pitch diameter, and other parameters based on the specific application requirements.

Tooling Selection: Select the appropriate cutting tools for the gear shaping process. This typically includes a shaping cutter with the desired helix angle and profile corresponding to the internal gear shape.

Machine Setup: Set up the gear shaping machine and mount the workpiece, which is usually a blank disk or pre-machined gear component. The workpiece should be securely held and aligned with the cutting tool to ensure accurate gear tooth profile generation.

Shaping Process: During the gear shaping process, the workpiece and the cutting tool (shaping cutter) rotate in their respective synchronized motions. The cutter is gradually fed into the workpiece, while both rotate to generate the gear teeth. The cutting action is controlled by the indexing and feed mechanisms of the shaping machine.

Finishing Operations: After the initial gear shaping process, additional operations may be performed to refine the gear teeth, remove any burrs or imperfections, and achieve the desired surface finish. This can involve processes like grinding, honing, or other finishing techniques.

Throughout the gear shaping process, precision and accuracy are crucial to ensure that the internal gear's teeth conform to the desired helix angle and achieve the required fit and functionality within the gear system. It is essential to follow proper machining practices and utilize appropriate equipment to produce internal gears with a 50° helix angle accurately. Additionally, it is worth noting that the specifics of the gear shaping process can vary depending on the machine, tooling, and manufacturing methods employed.
