Drilling holes into pockets- RETRACT

[mike561h]

Hey Friends,

 

I have 10 pockets 3 holes in each pocket.

Drilling from Z-1.2 to Z-1.5. I have set Z incremental to .1 to keep drill down for each 3 holes in each pocket. Is there a trick to have the drill pull up and clear Z after each 3 holes in the pocket. Or do I have to program each pocket seperately has to clear material between pockets. No reason for the drill to start at Z0.

I hope I made sense.

set your clearance to .1 absolute and DO NOT check the box that says to use clearance at the start and end of the operation. What this will do is output a G98 in your post. So you will see the machine stop at.1 above your part then in the G81 command it would drop into the pocket drill. Once it is done drill it will come out of the pocket and return to the inital plane that was set the z move before the G81.

Try this I think my memory is correct. I would back up the Z run a couple of holes first then dive in to the part

Clearance .1 abs

Use clearance at the start and end of the operation = do not check

Retract -1.1 abs

Top of stock 0 abs

Depth -1.5 abs

 

Just one way of doing that.
