Drilling

Is that possible for drilling If bore diameter and tool diameter are same ?

Re: Drilling

Yes, it seems to be related to solid tools, using auto depth calculation.

If you specify a blind depth, it will just follow the depth as specified.

But with Auto Depth, it will have to compare the diameters (even if you select TIP and not SHOULDERS).

Re: Drilling

Yes, the drill is going to follow the specified axis regardless of the size (or even the existence) of the hole. That is my experience anyway.

Re: Drilling

It will follow the hole/bore if the drill is on size or smaller than the hole. I run into an issue with solid tools(drills) that are built on size but the engineer makes the hole to a rounded number like a .4375 diameter drill and an engineer makes the hole at .437 forgetting to add the .0005 it will not drill that hole because the drill is too big . I ask the engineers to always round the hole diameters up whenever possible to like .438 diameter.

If they don't do this (which is quite often) I then have to change the model myself or force the drill through the hole. I don't like forcing the drill because it is more work for me to drill to a depth because I have to take extra time to measure the depth and add it to the drill or find or make a surface do set the depth to.

This is a big source of frustration to me because of engineering ignorance!!

OK, that must be an issue with using solid tools then. If you are not using solid tools, I am pretty sure you can put any size drill into any given hole size.
