For a non-cnc guy, what is '2.5D'?
I'd actually say the scallop on the front side is far more £d than the parallel on the back. On the parallel the work "puts on a cut" in the X direction (the 0.5) and cuts using Y & Z (the 2.0D) giving the total 2.5D, if you watch the DRO readout at the end you can see X only moves in steps between cuts.On the Scallop the tool is constantly moving in all three planes so true 3D.JPS Jo thanks for moving things I was actually thinking of PMing Mike and asking if he wanted me to move my earlier reply to a new thread rather than hijack the build.
Maybe I was confused by the title of "Advanced 3D CAM..............." and thought that it was a place to discuss 3D CAM
Mike:Back in Post #338 you showed a screen shot of the dry sump that showed the depth of cut for each layer. How did you generate those lines? I've got my suspicions, but "Enquiring minds want to know".Don
