I've successfully projected the image I want to engrave onto my piece and have been able to generate a tool path. What I can't figure out is how/why HSM is defining the tool path the way it is.
My first attempt involved projecting a simple line drawing of the image onto the surface of the part being machined. This line drawing was created by importing a block into SW2020. In the geometry tab I selected the sketch directly from the feature tree. HSM did not recognize the image and returned the "No contours have been selected" error message. I replaced the simple line drawing with a sketch made up of closed contours (outside and inside) thinking that the 3D Projection would evaluate the sketch and run the tool down the middle of it. The tool is a .0625" flat bottom end mill. This matches the desired width of the engraving. Unfortunately, the center of the tool is running on both the outside and inside contour. This effectively doubles the width of the engraving to .125". I've come up with a work around by selecting Stock to Leave and entering .03125" but I'm wondering if there is a better way. Specifically, is there a way to get the center of the tool to run directly down the center of the sketch?
I can't attach any files of the part due to a NDA.
