![]() ![]() Additionally, if the solid model has the chamfers modeled in, you’ll need to create another form tool with the compensation point at the lower cutting edge. You get a “step” in the tool path and may cause gouging. If your tool diameter is also close to the minimum cutting radius, avoid steep Z height changes along 3D contours. ![]() Some caveats however, if your tool diameter is very close to the minimum cutting radius be sure to use feed optimization option. This is where this method really shines, when we use our new form tool and create a 2D contour or Trace or pocket for chamfering we don’t need to apply any hacky work arounds in the “stock to leave” box or play with the contour height selection, or even need to make a template tool path, it just works! Select the 2D or 3D contour that requires a chamfer and you’re good. And that’s it! The new form tool is in your tool library. When we create the form tool we select the tool profile we created, select the axis of rotation (arrow points down), and most importantly select the compensation point we just created. ![]() But we don’t want that so we need to tell Fusion where we want to compensate the tool point.Ĭreate two construction lines of the L6 area of the tool and make a right angle triangle.ĭimension one line as the length of the desired chamfer.ĭoing the above gives us the compensation point for Fusion and gives us a consistent chamfer dimension. Normally, this point is the revolves centerline at the lowest Z height. Now here is the clever bit, to get Fusion to recognize the tool as a back chamfer tool we need to define the tool compensation point. On the same plane, create a new sketch and draw out HALF of the tool’s profile with the sketch origin being on the tool’s centerline. If you’re using a tool manufacturers’ drawing, select “insert” then “DXF” and select the plane you want to insert on. We want to make a form tool which matches the geometry of your selected tool, here are the steps: You can also setup a parametric template to use in the future if you’re so inclined. If your tool of choice doesn’t have a 2D file, you can always draw it from scratch using provided dimensions. The NYC CNC YouTube channel focuses on all things CNC, including Fusion 360 CAD & CAM Tutorials and CNC Machining parts. Iscar makes it very easy as they have files package for every tool. Whatever tool you’re using you need to bring it into Fusion360. ![]()
