    Tooth Geometry

    The helical tooth profile, lead, tooth thickness and tooth-end contour are key machining controls. If the drawing specifies a multi-start worm, the angular starting position of each start must also be controlled.

    Bore and Tooth Alignment

    Where the drawing uses the bore as the shaft-mounting datum, the bore diameter governs the fit. Radial runout of the tooth section relative to the bore axis can cause variation in mesh clearance, so that relationship needs to be controlled to the drawing requirements.

    Workholding and Deburring

    After parting off, the small component offers limited clamping surfaces for secondary work. The setup must protect the tooth flanks from clamping marks. Deburring at the tooth ends and bore mouth should remove raised material while preserving the working tooth profile and bore entrance dimensions.

    Project Value

    This case illustrates the need to coordinate worm tooth geometry, bore location and edge finishing in a compact brass part. The controls depend on the specified fit and meshing requirements of the mating assembly.
