Flat Knurl - invalid tool type for milling

[Anonymous]

Hi All, I'm trying to mill a knurled appearance into a flat piece of brass using a 90* drill mill. I'm using two parallel toolpaths set 60* apart from each other, but any pointed tool (or form tool) I select gives me the message "Invalid tool type for milling." I've tricked Fusion before by picking a similar-sized ball end mill when I post and putting the 90* cutter in the spindle instead, but I'd rather have a more accurate simulation of my results. Any way around this?

Thanks in advance!

I think a chamfer mill should work for what your after.

Hi @Anonymous,

I know it is sometimes stuped that a specific tool can’t be used for specific operations. 

But like @johnswetz1982 said try other tools with the specific geometry and see if they are allowed.

@Marco.Takx @johnswetz1982 thanks for the suggestions, but I've already tried everything - chamfer, spot drill, center drill, countersink, taper, form mill, and even drill. Pretty sure there aren't any other options. I get the "Invalid tool type" pop-up every time.

Can you export and share your Fusion file so we can have the best picture of what you are doing, what you've tried, and what you've run into?

I figured it out - mostly. Chamfer IS the correct tool to use, but it won't accept a tip diameter of 0. I set it to .001" and the toolpath was created with the simulation I was looking for, but also with a warning that stepover exceeds the cutter diameter, and tiny horizontal lead-ins/outs, even if I set them to 1in. File attached.

For what your doing the warning can be ignored.
