Hello, I am a CTS (Career and Technology Studies) Teacher in Alberta, Canada.
I have CNC as part of my Design Studies Class. MOST of what my students want to do, I can figure out, but between a lack of funds for training (It's K-12 Education) and my student pushing the limits of what we can do (which is great, but I am not sure how to do what he wants to do lol). I need a bit of help.
I am not Just teaching Mastercam in my class. I have 2-3 students a semester who do Mastercam/CNC projects. So it isn't my strength. But I like to encourage my students to try different things.
Running MasterCam X9.
In the sample picture I have provided (The file he is working with is a bit more complex, but the same idea) I have a circle that we want to cut out in a solid material, with leaving the inside shape (rectangle here) still raised to the original material height. So a pocket idea, but not cutting all of the material out leaving a sticking up portion. It isn't turning out right when we do this. We are having troubles getting it to NOT cut the rectangle portion.
I don't know how we have to create this in 3D, or tell it to not go into a certain area, etc. etc.
I also included the BASIC file that we are using as a test for how to do this.
Any information/guidance you can provide I appreciate.
Thank - you.
Philip
