Groove MakerISO 14 / DIN 5480 splined shafts, hubs and splines for Fusion 360

Groove Maker generates standard splines in Autodesk Fusion 360: a complete splined shaft, splines cut into an existing part, or the female hub that mates with it, to ISO 14 / DIN 5463 (parallel sides) or DIN 5480 (involute).

Who is Groove Maker for?

Groove Maker is built for mechanical design offices that model shaft-hub connections in Autodesk Fusion 360: product designers, draughtspeople and manufacturing engineers. It helps machine shops that need to produce a standard spline from a clean model, without retyping dimensions from a standards table. 3D printing users and makers use it to reproduce an off-the-shelf part, repair a gearbox or fit a printed hub onto an existing motor shaft.

The problem it solves

Splining a shaft in Fusion 360 is a manual job today: look up the diameters, spline count and tooth width in a standards table, draw and constrain one profile, repeat it in a circular pattern, then remove the material. With DIN 5480 the flanks are involute curves, which cannot be drawn with a simple arc. And the hub still has to be modelled, with the right clearance, so that both parts fit together.

Any change of diameter means starting over. Groove Maker does the job from a few parameters, and redoes it just as fast when the drawing changes.

Three commands

• Create splined shaft: generates a complete cylindrical shaft with its splines. Set the total shaft length, the spline length (for example 30 mm of splines on a 50 mm shaft) and their offset from the end.
• Apply splines to face: cuts splines into a part you have already modelled. The diameter of the selected cylindrical face is measured and the closest standard size is suggested. Stepped shafts are supported.
• Create splined hub: generates the female part, a cylinder bored with the mating profile. The assembly clearance applies to every face (root, flanks and tooth tip).

Features

• The three buttons are added to the Design workspace, Solid › Create panel.
• Real-time preview with every change.
• The OK button stays greyed out as long as the parameters cannot produce a valid part: the error shows up straight away.
• Optional entry and exit chamfers.
• All operations are folded into a single named timeline group (Shaft_6x21x25, Splines_6x21, Hub_6x21x25…); each operation remains individually editable.
• The resulting parts are ordinary Fusion bodies, editable even without the add-in.
• Interface in French or English, following Fusion’s language.
• Windows only (.exe installer); macOS is not supported.

Supported standards

• ISO 14 / DIN 5463, parallel sides: predefined standard sizes (N x d x D), picked from a list.
• DIN 5480, involute splines: the profile is computed with true involute flanks. Module, tooth count, profile shift and pressure angle (30° by default) are pre-filled for each standard designation; tip and root diameters follow table 1 of the standard.
• Choice of DIN 5480 manufacturing method (broaching, hobbing, mill-broaching, cold rolling), which sets the root diameter; diameters remain editable by hand.
• Custom mode: free input of the tooth count, diameters and tooth width.

Limitations

• Apply splines to face: external cylindrical faces only (no bore, no conical face).
• Hub: the bore runs through the whole hub length; blind bores are not supported.
• In 3D printing the process adds its own clearance: a test print of the shaft + hub pair is still recommended.

Groove Maker is a design aid: always check the resulting geometry before manufacturing or strength calculations.
