Once I had the jaws in position, I used “between two faces” joints to position the part on top of the jaws, centered between them. Making Jaw Blank Bodies Positioning the Part These, I can carve in this design, and the imported models become the stock for the setups. Instead, I used the surfaces of the parts to extrude new bodies the same size in the same position. The jaws in this case are linked designs, so I can’t model the cuts directly. Setting the Jaw Spacing Making Machinable Bodies I guessed how far apart they needed to be and then adjusted later. The jaws are joined on their faces with an offset to set the distance between them. It also keeps setup and fixture elements from finding their way into the drawings. Unless it’s a very simple operation, I find this more convenient than trying to do the CAM in the original design. I usually create a new design and mock up the entire setup for the CAM process. In my case, I already had models of the vise jaws because I made them in a previous video.įor the CAM workspace, I created a new design and imported the soft jaw models as linked designs. The first step is to set up models of the jaws in Fusion 360 so we have something to carve. The goal is to model a set of soft jaws with a recess to accept and firmly grip the milled portion of the part. After milling the basic shape out of a solid block of aluminum, there isn’t a good way to flip it over and hold it in flat vise jaws. In case it wasn’t abundantly clear, the reason we needed soft jaws for the motor clamp is because it doesn’t have parallel sides. If so, feel free to comment and let me know. YouTube viewer bostondan77 asked in the comments how I set up the CAM to carve the soft jaws and I realized that I skipped right over that. In the previous video, I used soft jaws in the mill to hold the toolpost grinder motor clamp so I could mill the back side. This is just a quick video showing how to CNC mill soft jaws using Fusion 360.
