Wes, what exactly is "radial fit conflict"? Colin, I tried messing with the direction button (tool path parameters/surface parameters tab) but didn't seem to have much luck with that. Also, where do I define reference points? Forgot to mention that I tried to use an aggregate head... apparently it only works in Mastercam Router??? (I'm using an X4 mill package) Heres the link to the mcx file I've been working with. Spose I shoulda added it in the first place. It shows the closest I've managed to get. http://dl.dropbox.com/u/24962051/HALEYS%20BALCONY%20CORNICE_FRONT_R1.MCX

I got issues... mostly just programming ones I want to program using a 28" diameter saw blade to cut lineal stone profiles. I've mostly been using the first process as outlined below as our main machine was not very accurate in the Y axis (that's the cutting direction, horizontal and parallel to the blade). But now we've set up a new 3 axis saw and I'd like to be able to use the cutter comp in Mastercam X4 to effectively program more complex stuff. On straight pieces (picture crown molding) I can use a endmill with the diameter of the saw kerf and the comp is fine... its all lineal passes in the Y axis with an X and a Z move between every pass. BUT... when the same profile has to go around a radius I get gouging in front and behind the blade. Picture holding the ends of the crown molding at the table and arching the middle up. The saw then runs lengthwise along the piece while following the surface up and down in Z. The greater the amount of arch then the worse the gouge gets. For example, if it was a 180 degree arch then at the point where the arch is vertical the cutter comp is only half of the saw kerf... and I need it to be half of the blade diameter. Oh yeah, if its a flat arched surface I can define a 28" diameter ball end mill and that works. I've been trying to use a huge slot mill and set the tool plane as right side. I can't seem to get the cutter comp to read the outer perimeter of the tool and it also seems like m-cam is applying the max stepover parameter in the x/z plane instead of x/y. Thats even though the cutter comp plane is set to top. Got all frustrated and tried about every plane combination possible under the surface finish parallel parameters-toolpath parameters tab. None seem to work. Anyone have ideas?
