Carbide drills. Yes, and also a reamer to follow.

In order to correct material moving, what would you do lower the feed and speed? I know essentially, you don't want any movement. However, to counter from machine not being 100% efficient as far as drill walking would this method help?

Drilling oversized and drilling undersized on Fanuc machine? I've asked before but I can band-aid this by slowing down feeds and speed. Just want to know the cause my drill is size is 8.542 and my reamer is 8.792. The runout is 2 or 3 microns on the end of the drill and reamer. Here is a video...

I appreciate the help I can slow down the feed and speed and it corrects it.

Apologies updated. This is just the reamer can't send the whole drilling cycle, but I'm noticing perpendicularity and undersize issues and its only these 2 holes you see the drilling on.

Any feedback will be helpful

Correct, however this uses drill and a reamer, I've tried to spot drill to counter for if it's flexing didn't help. Here is a better visual 4 small holes

This is the setup it's the small holes that have the issues, current estup has overhead clamps and collet clamping.

"There is unlikely to be a Fanuc instruction that says "Make random holes incorrectly." Thanks I needed the aerospace expertise for that.

Just remember 2 of the 4 holes are always good. Feeds and speeds always the same. So I'm running into issues with perpendicularity, from one hole to another. There is a interior clamp and one on the top of the part. this is just a quick drawing that doesn't show the inside ID this part has or...

So we drill parts that have a 15 mm gap between the 2 surfaces however when drilling we have misalignment issues when going from one hole to the next hole

Drilling two thru holes issues with perpendicularity, same spindle speed and feed all for all holes, but having issues with 1 or 2 holes being misaligned?
