Granted that I am a beginner in using mastercam, I need some help in understanding the methodological approach needed to implement surface toolpath (rough and finish). As case of study I have got a set of surfaces describing a 3D open contour. As first operation, I have used surface rough contouring by leaving a stock of 0.3mm and using a boundary 2D chain as containment boundary (the tool is restrained to path internally the containment boundary). The result is that the toolpath is enough even and smooth and follows smoothly the drive surfaces pattern selected. As second operation, I have used surface finish countouring by selecting the same drive surfaces and containment boundary used for roughing operation. I have set up the stock to 0.0mm and kept the rest of default parameters. The result is awful. The toolpath doesn't follow smoothly the drive surfaces and presents a lot of "break and retract motions". If I set up the stock to 0.02mm the toolpath is almost smooth and acceptable but I don't understand why I have to introduce a fake stock of 0.02mm to have the toolpath almost acceptable. My goal is to have a toolpath which follows smoothly the drive surfaces selected (without fake stock value) since these surfaces are part of finish machined 3D geometry. I also need help in understanding how to use rough and finish flowline toolpaths properly. How does Mastercam interpret the drive surfaces as flowline ruled? Sometimes I get an error message telling me "Surfaces selected not aligned or ruled" also in case the surfaces selected, at first sight, look like flowline ruled in the same direction. Is there a tool in Mastercam that could make a checkout of drive surfaces giving a response about inner flowline direction of surfaces checked and giving the chance to modify such direction? Any suggestions to help me in understanding how Mastercam approach what highlighted above? Are there some exhaustive tutorials clearing out these doubts? I will be really thankful.
