Steel piece renewal
I'm adequately acquainted with linear motion (I have built two 4 axis CNC hot wire foam cutters based on Carken Co. cutting soft+controller and Hobbycnc Co. stepper driver).
Unfortunately my new application is different.
I have a steel piece. Some faces of may piece are worn and I want to renewal them using TIG welding procedure. The 3D CAD design of my piece is available. I have also the possibility to scan my piece and to get the 3D CAD shapes of the worn faces. My problem is to build a 3 axis CNC gantry capable to drive the TIG welding head in order to automatically fill the piece up to it's designed profile.
Could somebody help me with some suggestions about solving and affordable software I can use ?
Thank you for reply.
