ollie Posted September 7, 2008 Share Posted September 7, 2008 Alright. I'm looking into create a lisp program that will test to see if a tool tip would be able to cut a material without interfering with the desired shape. fore example: If the tool tip is 12mm cutting on the outside any arcs that are smaller than the radius of the tool would cut into the actual profile, (assuming the arc wasn't meeting the profile at a tangent. I think this can be done with dxf group 90 and off setting the profile to see if the number of vertices change. I also would like to know how to control whether an offset goes inside or outside . Any thoughts? Cheers, Ollie. Quote Link to comment Share on other sites More sharing options...
CarlB Posted September 9, 2008 Share Posted September 9, 2008 Are your tool paths polylines or splines (or either)? Does your path "close", otherwise there may not be an inside or outside. A lisp could check the path for any radius less then the tool tip radius; and could determine points inside & outside of a closed path. probably could determine if path crosses itself, not sure how offhand. Could you post some examples of path/tool conflicts? Quote Link to comment Share on other sites More sharing options...
