So I suspect because my curve is NOT symmetrical - but the scale here doesn’t work. You can see the pic below. Now I’m kind back to square one……

You can determine a precise measurement if you use the method that @KPeter suggested. If you want to specify the diagonal dimension then you need to divide that number by 1.414 and use it as the offset for the chamfer. (Example: a 0.5" diagonal dimension would require you to use a chamfer of 0.354" x 0.354".) The beauty of using Peter’s method is that you can change the angle of the chamfer to be anything other than 45° if you like. The 2nd half of the video shows Peters method.

The following link can be used to access Whiteside's Library of Fusion 360 .tool Files for our most popular CNC bits. These files can be loaded into Fusion 360, and PDF files with drawings of each tool are also available on each product page.

YES —- I saw previous posts; but these only show how to taper a chamfer on one end. I figured out how to scale ONE end and have the chamfer trim down to zero (see screen snapshot); but I want the chamfer to taper down on both ends.

Here’s a possible workaround. I subtracted a cylinder that was angled at 45°. The radius of the cylinder is smaller than the radius of the contoured part you wish to have a tapered chamfer.

2) Always wear eye and ear protection along with dust masks. Avoid using bits while in loose clothing. Keep hands, body, clothing and hair away from the cutter.

Here I put together a way for you to measure the chamfer at the center of the arc. In this example I chose a 0.5" x 0.5" chamfer. Therefore the diagonal dimension is 0.707". The Scale method does a nice job of bringing the ends to a point however it also scaled down the center diagonal as well. The ends are not exact but can be adjusted close by tweaking the scale number as I did in my example making it 59.7%.

I do want to say to the Sharpr 3D folks monitoring……… we need a work around here. This is a sort of work around, but it’s not MEASURABLE; that is I’m cutting a shape with another shape, but I can’t measure and get the “cut” or the chamfer I want.

3) Do not remove safety guards, and be sure to always feed against the cutter rotation. Never use dull or damaged cutters.

Hi, I have a curve (part of a guitar body); and I want a deeper chamfer in the middle of the curve, and then I want it to taper on both ends of the curve.

I kind of don’t want to redraw my whole body, and make it TWO bodies; because in the end, I’ll 3D print it, and I need it to be one body.

Each side of the instrument is unique. My gut feel /guess is that I’m drawing a circle, that’ll extrude to make the cylinder……but I’m not certain how/where to draw it?

I tried…… I followed, or as closely followed as I could, the video. Here’s the end results: something kinda what I want……but again, it’s not a MEASURED chamfer. [insert crying icon here; get out Fusion 360]

But I did think that you could create the “cylinder” by copy/moving the curves from the side of your original guitar body sketch and using that as the curved edge. Once you have this curved line, add a chord between its ends to create a closed shape you can extrude upwards, rotate around an axis passing through the curve ends and lower onto the guitar body for your subtraction.

I “think” what you did was ONLY scale on the bottom line of the chamfered edge, correct? I “think” I got it, or very close to it.

These .tool files are available as a recommended starting point to assist you in the use of our tooling. Cutting speeds and feeds may need to be adjusted based on your specific application, material, depth of cut, and machine capabilities.

Great! Nice to hear. Question: Does this meet your requirement as a MEASURED chamfer? If so, where is it measurable? Thanks.

Hi, FIRST……Thank you for your reply. secondly…… how specifically did you SCALE and get those results (a crescent or semi-circle with tapered ends, and a chamfer in the middle) ???

Thank you - the finished product is what I want. I’m not sure exactly how to get the cylinder positioned exactly where I need. I guess I can try to play around [more time]. I realize a tapered chamfer is rather complicated, but for a CAD tool it doesn’t seem too odd.

I understand what you are saying and what I had shown is a mere workaround. Here’s a variation that might help. Occasionally I will make a part semi-transparent to help me when performing a desired result. Interesting phenomenon is that the area where the Subtract took place ends up being semi-transparent, which by the way can be useful in certain circumstances.
