Custom pen project: Tip


Create the toolpaths required to rough and finish a custom aluminum pen tip using Autodesk Fusion 360.


A customer has provided a custom pen design for your company to machine a prototype. They supplied the 3D model and detailed drawing but are requiring your company to create the digital tool library, the toolpaths and to manufacture the part.  The pen tip will be used in a custom pen design using a G2 pen ink insert.

Further your skills by completing a project practice exercise and project challenge exercises that work on geometry and toolpath variations to validate additional pen concept parts.
