Drill, CBore, and Chamfer

[BCrosby]

I am constantly asked to slightly chamfer the entry and exit of holes that we drill in a CNC machine. This way, all the holes are deburred right out of the machine saving us having to hand deburr it afterwards.

When using the hole command I would love to have the option of adding a chamfer on both ends of a drilled or tapped hole and on the top of a counterbored or countersunk edge.

Currently I put the holes in and then use the chamfer command to add the this detail. The down side is when I detail the parts, the hole label does not note the chamfer so I need to use an additional label on the same hole or manually enter it into the hole label.

The hole label should be able to produce text that calls out the chamfer (or edge break) on this side, far side, or both sides in addition the the text that is currently available.

ex.

8,5 mm DRILL THRU

M10x1.50 TAP TAP, 20 mm DEEP

.035 x 45 DEGREE CHAMFER, BOTH SIDES

9 mm DRILL THRU

15 mm COUNTERBORE, 9 mm DEEP

.025 x 45 DEGREE CHAMFER BOTH SIDES

(keep in mind that my examples do not contain all the geometry symbols that the hole labels show but you get the picture)

There are also other hole functions that I need to do (but can't think of right now) in multiple steps. This makes me use multiple hole labels or manually edit them. Can you just expand our hole options beyond the basics??

I'm thinking you're not using the full potential of the Hole command, the Hole Note command and the Style library. 

Check out the Hole command first. You can decide if you want your hole threaded, counterbored and Through all, or anything at all, really. 

Then, when you create the drawing, choose the Hole note command. It will detect what kind of hole it is, and everything that needs to be included.

This is what the note looks like, with my settings:

If you need any other information, no big deal. Double click on the note:

You can un-tick Use Default and you can tweak the information presented.

If you want any other kind of information, use the Style command,  go to the Dimension item in the browser, choose the dimension style you want to modify, and open the Notes and leaders tab. There is a drop-down window that details every conceivable type of hole that Inventor can make. They are all individually customisable. 

The only thing Inventor does not do, is chamfer both ends of the hole in a single command. Maybe in a future release?

Cheers.

I'm fully aware of all the hole possibilities and the style editor options. I wouldn't say that there is every concievable option available. In the example of chamfering both ends of the hole, that is a possibility. I could present other hole designs that I use on a regular basis that can not be created with a single hole command which in turn can not be labeled with a single hole note. I would like all hole options available to me so I can pick and choose how I construct a hole and not not have to pick one of the limited options that Inventor is currently offering.

Here is another one that I had to do yesterday.

.625 DIA. REAM THRU

7/8 DIA. DRILL, 2 5/8 DEEP

1.005/1.006 DIA., 1 DEEP

.063x45 DEGREE CHAMFER BOTH ENDS

All I'm saying is that the hole command needs more flexibility built into it so that whatever crazy hole options we need can be produced in one hole command since it is one hole. I also want to be able to completely label a hole with one hole note and not have to manually edit them.

@BCrosby and @Anonymous: There is a request for the near-side/far-side/both-ends hole option HERE which you may want to cast a kudo for.

In regards to the rest of the hole functionality, BCrosby, could you make a list of specific hole operatioins you'd like to see added that aren't possible now? Even if you can't think of all of them now, just list the ones you can think of, and mention more later if necessary.

The more specific you are, the easier it is for others to recognize if they could benefit as well and give your idea a vote. Also, the more specifc you are, the more likely it is that Autodesk will implement what you need.

Here is an example of a hole that I had to create today.

I would like to be able to do this in one hole command and label with one hole label.There should be one hole label produced that shows the a machinist what needs to be done and in the order that it needs to be done.

The desired hole label would allow me to show

1) Pre-ream drill size (similar to a tap drill)

2) A combination of fractional and decimal dimensions (this gives a general idea as to the accuracy desired)

3) Tolerancing

4) C'sinking in addition to a C'bore (this side, far side, both sides... could be signified as TS, FS, BS) Currently, in one hole command, you can c'sink or c'bore not both and not both sides.

Agree on your last example there. Sometimes more options would be nice. Counterbored hole, with a chamfer and then a tapped hole after seems to be rather common.

Having to do custom notes on every hole dimension does get old.

Going to bump this one up as I was about to submit a similar idea. Had a customer who's come from Solidworks asking how to dimension this hole feature. He had got as far as the image below by adding custom text alongside the hole call out, putting in references to model parameters so that it updates with the model.

Having all the hole features in one dialogue indicates the process order for creating the feature and ties them all to the same positional tolerance.

Even if it were possible to have a parameter references in the hole dialogue you could then create your own where Inventor is not ready for more complex hole features.

Maybe a hole command that we can add features to it, and even save it.  First you add a hole, then add a chamfer, then add a thread if needed, or a counterbore, or multiple counterbors.  As you add these features it remembers all the commands so when you dimension it on the drawing it will add all the callouts that are in that particular hole.  Also have the ability to modify the description or reorder the callouts as needed.  Then maybe even save these holes in the content center for repeated use.  But it would be important to treat these as holes not as ifeatures so that we can use sketched points, or concentric data and etc to place them just like holes would.  And also be able to pattern them and reference those patterns just like holes would.

@dan_butler_komatsu Can you explain with a screen cast or an image?
