Defining 3 axis machine with manual rotation of tool

Greetings

 

In the shop we have an old Maho machine which has 3 axis and it has manual rotation of its milling head. There is a part with a almost 30 degree surfice that requires a finish pass. I do not know how to define in Fusion360 that the milling tool is at an angle but the machine axis orintation is still aligned with the part.

I was thinking to define the end mill tool as a taper tool to circumvent the problem but maybe there is a more proper soultion to this problem.

Any advice would be much helpfull.

Hi.  Does the mill have a coordinate rotation function?

Are you looking to do something like the image below ? I am thinking the part will be setup to be cut in the Y direction ?

If so the try out the attached file, it is a simple 2D Contour with Multiple depths, I have done it this way because I don`t know how/if you have already removed a lot of the stock and only need a finish pass, if that is all you need then just disable the "Multiple Depths" and it wil just do a single pass at the surface, best I can do without your Model to work from.

I have set it up so that the passes are done in the Y axis so the table will move in/out on the Y, the position is moved in the X and Z to do the ;eft and right moves, so it moves to position in the X and Z, then cuts in the Y, moves again in the X and Z for the next cut in the Y and so on :slightly_smiling_face:

Hopefully it will be somewhere near to what you need, as already stated, best I can do without your Fusion f3d file.

Example file attached, open the file in Fusion and first run the Simulation and click on the "Info" tab and you will be able to follow the X/Y/Z moves, I generated some code here and it looks OK but not having the PP that you are using I am not uploading it as it is not likely to be correct for your machine :slightly_smiling_face:

We can using 3D surfacing to remove all the materials and leave only 0.010" for finishing, then we can use the "PATTERN" method to finish the angle; which allows us using smaller angle tool to finish the big angle. Hope this can help him.

Sorry for replying a little bit late . Sending the part together with picture of rough demonstration of the setup.

OK, is the image below close to what you need ? 

If so then it is just a simple 2D Contour with the "Tool Orientation" used to get the angle of the tool, I created a surface at 90 deg to the angled face to use as the Z face for the orientation to match the angle of your Head.

Modified file is attached, I used a nice big 16mm End Mill as I have no idea what tools you have :slightly_smiling_face: Feeds and speeds are up to you :slightly_smiling_face:

I am not sure because I only work with 2.5D parts but I think that your examples makes the Fusion360 thinks it is a 4 axis machine. My machine is 3 axis but the head can be rotated manually.

That`s OK, I didn`t know which Post Processor you were using, it is correct, the Tool Orientation is not supported in that PP.

 

So, I have removed the orientation and tested it with the Maho Phillips PP and it generates OK, just means that it cannot be simulated in Fusion but all you need is the 2D Contour and the correct setup at your machine as the tool is already at the correct angle all it has to do is go to the correct X and Z positions and then do the cut in the Y so it is down to your settings at your machine, try it now  :slightly_smiling_face:

Reckon you could do that easily at the machine control without Fusion :slightly_smiling_face: :slightly_smiling_face:
