My First CAM Project in Inventor

@ClintBrown3D Autodesk Inventor 04-min

As part of my AU London class this year, I am building an electric guitar using the Autodesk Product Design and Manufacturing Collection. For the Class, I have already built the guitar, sculpting the body with hand tools.

The initial design starts with a PDF, which is imported into AutoCAD, this geometry is then used In Inventor to shape the body of the guitar, check out the blog post here:

Below is a picture of the initial test fit of all the parts (finishing of the body still to be done), and then some progress pictures of the body being shaped.

I am hoping to also machine a body, and in preparation of AU London, I have put together a 10 minute video showing my setup in Autodesk Inventor HSM, or Inventor CAM as it is now called.

Methodology:

I’ve chosen a 10mm flat end mill for the facing operation, my thoughts being that on a desktop CNC, there would not be a huge array of tools and I don’t expect to have access to a face mill.

Note that the video does not address clamping (although I mention some thoughts towards the end) and I should go back and edit some of the machining operations to set the coolant to “Disabled”, as we are cutting wood on a desktop CNC.

Keep an eye on the blog for updates on the guitar.

I have to say that this is rather exciting, one of the first things I ever did in Engineering was to manually program a CNC lathe to machine brass billets, manually programming G Code took a long time, and it is mind blowing that 21 years later, I am able to do some relatively complex Milling in under 10 minutes.
