Thread: Indexable drill programming

Using an index-able 1.25" drill and 90 degree as the cutting angle, drill cycle 1 bottoming. when the drill initially starts to cut the feed is slowed for .6" then picks up to programmed rate. I'm think that is to help a standard drill to get a good straight start. The problem with the index-able drill is that in aluminum the chips initially are too thin and don't break well and make a rats nest from time to time.

Would it be better to choice another drill cycle or use "other tool" with bar in to avoid this slow initial feed? I swear that I have never had this problem before so I'm thinking its the wrong drill cycle or tool definition. The manual says nothing about initial feed rate.

T32-B

That half feed is set in the parameters somewhere.

What I did, I set my indexable drills as boring bars, since I usually took a pass or 2 with em after drilling the initial hole.

I just programmed the drilling part as a manual unit. 3 whole lines, pretty easy. Unless your using one of these damn T1's, then its 2 manual units to clear for the tool change.

Is it possible to set the drill point to 180? (That's what it is eh?)

hi
program as peck and on the first peck set it to the depth you want to drill

180 work like a charm.
