Choosing the Optimal Tool Path

billB2FDG — Tue, 30 Jul 2019 18:01:25 GMT

I use adaptive clearing with little trouble, buy NYCCNC stresses, it is not a finishing strategy. So, I am trying to interpolate to reduce the OD of a cylinder. AC works great, but I check Stock to Leave 0.020". Then I click on "Derived tool path" > 3D comes up, and from there, I don't know what to do to get the cutter to take a finishing pass. This is a general problem too. I have difficulty from a general standpoint too. I attached an image of the drawing for whatever it's worth.

Also, I would like to use HEM to cut the full length of the cylinder at one with a smaller RDOC. I need help. 🙂

When creating a Derived toolpath, you are only given the option from the same menu of the parent toolpath. 2D Toolpaths will only allow Derived 2D Toolpaths, and 3D will only permit 3D.

Looking at your part, I'd just use 2D Adaptive, thus giving you the options of all the 2D Finishing toolpaths

Thank you so far. So, what would be the perfect tool path for finishing the part?

2D Contour or 2D Circular would both be excellent choices

OK. So when I select the 2nd tab (I am not at my computer), what geometry to I select? I try everything and I get weird tool paths or it won’t even generate a tool path. I get the yellow triangle warning. Thank you for your patience.

Could we possible talk over the phone this evening?

When you get back to the computer, export and share your Fusion file.

File > Export > Save to local folder. Return to thread and attach the .f3d file in your reply

Seth,

I think I stumbled on to a solution. I would appreciate if you would still look at my file and see if it the best it can be. Thank you so much for your help!

Yep, that will work. One suggestion I have is to perhaps consider doing with a 2D Contour instead. Only reason for that is if you turn "Repeat Passes" on, 2D Circular lifts up and comes back down, whereas 2D Contour stays engaged against the part. One other suggestion is to also use cutter compensation if the machine allows for it. This will allow you to adjust the size as needed.

Thank you, Seth!
