Drilling thousands of holes

jcramton — Tue, 08 Aug 2023 19:36:02 GMT

Hello everyone,

I'm creating a simple part, but it has over 6,000 holes in it.

I'm using a drill toolpath using the select same diameter option and Fusion seems to be unable to handle all of the holes and will freeze up anytime I try to open the toolpath box or change any options.

Is there a better way to drill all of these holes?

I've included the project file but I strongly suggest opening it with caution. For me at least it will consistently freeze/crash my Fusion

Thank you in advance

I think this can work as follows:

Create delimituns sketches around the number of holes that are automatically selected.

Now proceed as follows:

- Create drilling operation (do not select a tool)

- Select Equal Diameter in the Geometry tab

- The option Tool limit appears - Select limit

- Select tool

This way you can select the limit, before Fusion try to find the holes with same diameter

Even easier, provided that all your holes are spaced evenly:

1) Drill a series of holes, either along the X or the Y. You can constrain this with a sketch

2) Put that toolpath into a Pattern > Distance/Qty and specify the needed values

The one downside is that you can't specify ordering, so it's likely going to go down the line in the X+ direction and then increment up Y+ and back home, repeat the process.

Thank you for the suggestion, unfortunately it didn't work for me.

What I found helped a lot is switching the order from "optimtize order" to "order by X"

It's still incredibly laggy, but at least manageable now.

And just for reference I'm running a i9-12900K with 128gb of ram and a RTX A4000, so I doubt it's my computer

Looks like we posted at the same time Seth, I'll try that way too.

Thank you

It's not ideal ordering, but calculation was only 15 seconds or so for me, minimal freezing. My PC isn't quite a potato, but it's getting on in years (Ryzen7)
