Stand-alone Witness lines in X
Tim Johnson replied to Ken Erman from CNC Software Inc.'s topic in Industrial Forum
Peter, I've just tried the ordinate dimensioning without changing the globals. It does put the arrows on. It's fine for most drawings, but some have so many dims that the arrows simply get in the way. If this choice is removed I will figure out a way to change the arrow size. (I think) -

I use them when I'm dimensioning ordinate. -
for boring use carbide bars if you can afford it, or heavy metal bars. It's amazing how much difference there is over a steel bar. Also split sleeves are much better for holding your bore bars than bore bar holders. (cuts down on vibration tremendiously).
-
A crash is usually louder on a lathe than a mill.
-
I too get the not watertight error. I have tried to verify with total fixture setups. but it's hard to machine inside a casting cavity when verify puts a lid on the part.
-
I'm running four different parts (3 pieces of a fixture I'm building one operation each, and two groups of the production part (two pallets, I can use the same tools on this segment).
-
Dan, If the groups are under the same .mc9 file, won't all the tools still show up?
-
David, The parts are going to three different machines. It's just easier on the operators to start at tool 1.
-
Mayday, There will be four different tool No.1s,four diferent tool two,s and so on.
-
Is there a way to seperate tools from different operations groups. I'm going to run 5 seperate groups with 4 different sets of tools and it gets confusing seeing four sets of the same tool number.

Need fixture ideas for holding thin, suspended floor thickness
Tim Johnson replied to MetalFlake's topic in Industrial Forum
Use jig plate underneath the part and rough leaving about .030 on the floor. Finish with a left hand spiral right hand cut end mill. It will push the material into the plate. Run at about half the rpm you would normally run and feed for your finsh. -
If you don't have 9000 rpm, then you may want to drop the feed to .004/.005 with .060 doc. Once the spindle hits max rpm, then your insert is going to cut at a lower sfm which will start tearing it up.

Thanks Jimmy.

In the job setup window, what the "head number equals tool number actually do?
-
I also find part zero and let the angle macro do the rest of the work. I also create work location programs so the zero point(s) won't have to be found again on the next setups.
