    I have a 3-axis milling machine. I'd like to mill a 'waveguide', basically a horn for a speaker. It needs to have a smooth continuous curve on the inside. It seems like it should be possible to mill this with a 3-axis machine if all axis are moved simultaneously, although I realise it is always going to be time consuming and the smoothness of the surface will be dependant on how many passes it makes.

    I could kind of do this manually if I made lots and lots of contours, say 0.5mm offset from each other.

    Is there another way to get the computer to mill it? I use Dolphin Partmaster, maybe another program is needed?

    I may of taken this the wrong way... but would it not be easyer to mill a mould and vacuum form this part?

    Yes you can do this.
    Open Partmaster CAM, open existing job, go to examples and select CAM then select contour with z profile.

    Run the file and you will see how t works by using a contour and a profile.
