I'm looking to control spot drill depth / diameter without the need to
add extra geometry / drill points.
The main point I'm trying to make with yet another Jon Banquer blog in-
depth look at CADCAM systems is:
At the end of the SolidCAM video the depth / diameter of the spot
chamfer is controlled regardless of where the geometry for the hole is
located and *without the need for points which you added*.
Perhaps a newer version of Gibbs with solids and hole recognition
might do this?
Regular Mastercam drilling can't do this without using Change At
Point, which is not used by most experienced Mastercam users because
the Change At Point user interface sucks in every way possible. I'll
take a look at Mastercam Solid Drilling when I get a chance. I looked
at Mastercam Solid Drilling very briefly and I didn't see a way to do
this. I might have missed something. Also, Mastercam's user interface
for Solid Drilling doesn't come close to comparing to how much easier
SolidCAM user interface for managing drilling is.
There is also an add-in for Mastercam for Feature Based Drilling. The
concept of buying an add-in to drill holes properly in a CADCAM system
is completely insane to me.
Cimatron's advantage with drilling seems to be that it can control
spot drill depth / diameter without the need to add extra geometry /
drill points *and apparently Cimatron doesn't need a solid to do it*.
I'm really not sure because I've never seen Cimatron drilling
demonstrated or screen shots taken of how Cimatron drilling works.

Ahh OK, I see what you want now. I didn't go to your blog before, so
I didn't see the hole feature recognition vid.
Cranked up my ol' Model T Gibbs, made three 5/16" holes, Z-3", Z-2",
and Z-1". Went to Gibbs' Wizards, chose "Hole Manager", selected the
Run AFR icon (Automatic Feature Recognition), it selected the holes, I
highlighted the holes it listed on it's mini-spreadsheet, then I
checked "Make Group". Chose "Drill Process" in that window (not the
normal drill process), then chose peck drill, clicked "Do It", and it
created a Operation Tile, rendered it & it drilled the holes without me
making any points or choosing any circles or selecting the holes
individually. It automatically went .0647 deeper on each hole, to
allow for the tip in my 135 degree drill. If I wanted the depth on the
holes to be changed I could change one number in the drill process and
it would change all the drill depths to match.

Some CAM systems have been sold on a modular basis for a long time.
No need to buy what you're not going to use, but if Hole Feature
Recognition is something someone could use, they should purchase
it. How much does it cost?
I'm not not clear whether Gibbs using AFR can do what I think a CAM
system should be able to do.... use one tool to spot for say 8-32,
10-32 and 1/4-20 holes that are on different Z levels where the spot
diameter needs to be different for each group of holes.
Is Gibbscam AFR able to do this and keep everything in one Operation
As you can see at the end of the SolidCAM video, SolidCAM can do this
and keep everything in one machining operation in the tree.
If Gibbscam is able to do this and keep it all in *just one Operation
I don't know and I don't care as I don't see the point in buying an
add-in to do drilling. When it gets to that point I feel its time to
change CADCAM systems. I also don't like the idea of using more than
one user interface for drilling as I feel that's bad CADCAM system

I'm not sure if Gibbs (or at least my version of Gibbs) "can" do it.
I'd have to play with it for awhile since I don't have any manuals at
home. Plus I've kind of used up my self-alloted time budget for
newsgroup cruising. Perhaps I'll play with it this coming week.
BB, you have the right idea. Give this place a break. Its too weird.
with all JB b/s. No different than the boob tube most of the time.
Oh well, just like every other good thing, it gets changed & screwed
up by the John Q. Public & Mr know-it-alls.
something's wrong I think , the start depth is different for
2 of the holes . if Z0 is for highest boss the rapid to and
retract height is correct for that hole .
so as I interpret this code , the drill will be cutting air allot
for 2 of the 3 holes .
looked at your web site your awesome <brownie points>
btw sorry for your loss , I lost my mom and sister within
2 months of each other , mom Alzheimer's, sis pancreatic
cancer .It was expected more or less for both but still
came as a shock .
Yeah, I noticed that in the graphic display of the toolpath after I
had made my post. It's not a feature I normally use, so I obviously
got some of the parameters wrong.
Why thank you. My homepage is pretty long in the tooth now.
Earthlink locked it (no additions or changes allowed) about 6 years ago
when they switched homepage creation programs. I never felt it was
worth the bother to create a new one, even though in the intervening
years some trick stuff has hit the floor, so to speak.
