Haas Post Drilling Problem.

[DazE]

Hi,


I have been machining a job that requires two holes in two seperate pockets that are 19mm deep. This means I want the drill to retract to 5mm clear before moving to the second hole to avoid a collision. The program I have outputs fine on my Siemens post but when I output through my Haas post it will only retract clear of the drilling surface before doing an x move into the job. I can get around this by setting a large clearance distance but I would rather have a post that outputs a nice z clear before any xy moves. I have set the linear move in the post to z output thenxy but it does not fix the problem.Anybody got any ideas where elseI should be looking?


Here is the drilling outputfrom the current post.


O00999
G90 G00 G40 G80 G17 G21
G00 G90 G54
T14 M06
G00 G54 G90 X26. Y4.5 S1000 M03
G43 H14 Z25. M08
G83 G99 X26. Y4.5 Z-34. Q3. R-18. F200.
X-26.
G80
G00 Z25.
M05
G00 G80 G53 Z0 M09
M01
G53 Y0
M30


The R-18 should be R5 ideally.


Thanks for any help.

You may not have a post issue at all. Go into the sequence parpmeters and change "cycle_optimize to "no" and post.

If you change the the G99 to G98 it will retract to z25. btwn moves..initial plane then r to your r plane r-18. during each drilling


the height you are at when calling the drill cycle determines what the initial plane is, in this case z25.


I know doesn't address any post issues... 2 holes

M97 is a cool Haas thing...local subs


Not sure if the G99 is good with other controllers.. but it does work with the Hass

Thanks guys.

I just need to remember to do that whenever I send to the Haas from now on.


Here is the new output with optimize set to no.

That will do me fine.
