Dave,
I created a rectangular contour and place several closed contours inside. I selected the 2.5D pocketing operation. Then I set the z-heights of the closed contours as well as the outermost contour. I let the workpiece default to the dimensions of the outer contour an ran the simluation. The simulation ran as expected with no errors and so I posted the code and set up to actually cut the part. The size of the workpiece for the actual milling operation was exactly the same size of the assumed workpiece. Early into the operation the machine broke the cutter. Investigating, it looks to me that the posted code created a rapid move into the workpiece which caught the cutter and caused to spin in the collet and dive into the workpiece. Should Sprutcam not have allowed a rapid into the workpiece or, in this type of project, am I supposed to define additional stock on the workpiece for protection during approaches/plunges? Dave, in case the answer isn't obvious, I am emailing you the project and the g-code. The problem started in the first 7170 line number when the rapid was set to 24 ipm with the tool breakage happening within the next 3 lines or so. The workpiece is 3.5" in the x direction and 1.75" in the y direction. Theorigin is set at x0,y0.
Thanks,
Terry
