Fusion 360 - Cutting angle on face

[pelseyHYPS2]

 hi. I am trying to face across the origin on this part that is mounted in a rotary. It’s a 12 deg angle from the flat down. It’s very much critical to quality that this angel is right. I can’t seem to get fusion 360 to track this correctly and all it wants to do it goofy moves anywhere. Does anyone have any ideas on what I can do to get this to program? I’m fairly new to fusion 360 but have 10 years machining on other software. It’s probably something simple.

Hi @pelseyHYPS2 

You could:

• create a tangent plane by using the cylindric face

• create a sketch on that plane
  1. use project function to project the cylindric face
  2. set the specifications of the angle and others (such as how far the cut is from the center and so on)

• extrude the sketch.

• mirror the feature

I attached the file so you can work with it step-by-step by going back in history marker:

Understood.

Can’t see why that matters, the part still has to be modelled.

@pelseyHYPS2 You can cut the four faces with a std 3 axis mill and rotary chuck, or other indexing vee block.  What is it in your setup that is the problem?

I need to track that angled line on my part face and I can’t seem to do it

[pelseyHYPS2]

I got the side angles down. What I’m struggling with is the face that is angled 12 devs

3 sketches each on the origin planes, 

front circle, then side view for long cuts and top view for short cut.

Use sketch 2 and 3 for split body tool.

Might help....

Is this a CAM question? 

[davebYYPCU]

I think so, but without a fie, or knowing what setups are being created, dead end.

It sounds like you are talking about machining with CAM.

I would like to know if it is Milling or Turning mill?

What specific machine do you want to machine on? It might be better if you tell me.

If possible, it might be better to attach the configuration file if it is ready.

Following up on our DM's, here is the video of the reply above, as promised.

I used some key shortcuts during the video:

D = dimension (can assign any dimension)

L = sketch line

P = project

X = change between regular and construction line

I = measure

Please let me know if you need anything else
