Okay so I got one I thought I would see what others would attempt. I am machining the part on a 4th axis Horizontal machine. I have the part sitting like it will be from the center of rotation. I got rid of the rest of the part since it is ITAR and only have the area in question shown. I wanted to machine the radius on the pocket using a 3/16 ball endmill. I have thrown just about every toolpath I can think at it and none gave me the results I wanted. I then old schooled it and offset the surface .09375 to give me the center line of my 3/16 ball endmill. I then went in and used create/curve/flowline with a .007 step over which should work for finishing the area I need. I then drew in the one area where the flowlines went the wrong way and know have full center lines at each .007 step. I then did a contour toolpath at tip in 3D, but told it -.09375 on the depth to get the correct contact with the endmill to surface. I tired Surface finish flowline, blend, contour and scallop and HST toolpaths and none gave me the results like I get using this way. This method I used of course take a lot more time so was hoping I am missing something here and someone who is willing to take a look and tell me what I am missing. The result of the 3D contour is what I want, but again what surface toolpath will give it? I even tried doing a 5 axis toolpath and the Multisurface 5 axis had the correct look for flowlines, but then did not get desired results either. As always thanks to anyone willing to take the time and look at this. Any help, suggestion or thoughts are greatly appreciated.
