Drill cycle retract help

[HEED]

alright, guys I need some help here I may have just been at work for too long but I can't figure this one out for the life of me, adn I know that I have done it before. I want to drill to 5.574, then retract to 7.2 position, then rapid to 6.425, drill, retract to 7.2, etc. my code looks like this,

 

( PLUNGE OUT LOWER )

T1 M6

G0 G56 G90 X.0204 Y-.7466 B0. A0. S1900 M3

G43 H1 Z7.2045

Z6.4259

G81 G99 Z5.5745 R6.4259 F8.

X-.1795 Y-.7184

 

I think that there needs to be a g98 in there too somewhere, right? I have used this cycle before to clear clamps, then rapid back to material, rather than drilling air. The kicker is that I can't get the clearance to post on a drill op of any kind, and I am nearly positive that that's the way I did it last time. Any help is appreciated in a major way I am losing it here

Heed,

 

In Parameter page under clearance plane turn off use clearance only at the start and end of operation. Or change the G99 to G98. Hope that helps.

I dont' have the use clearance at start only box checked, that's the wierd part.

Clearance should be set to your 7.2... DIM / ABS

Retract 6.4... DIM / ABS

Top of stock 6.3... DIM / ABS

Depth 5.574 DIM / ABS

 

There is a number of ways to do this, some of these can be set to INC depending on the Z location of the point picked.

 

You should be outputing the G98 instead of the G99, That is more then likely in your post, not sure how to change.

 

This is a quick example of what the posted program should look like.

 

N120T8M6

N130G0G90G54X0.Y0.S4000M3

N140G43H8Z7.2

N150G98G81X0.Y0.Z5.574R6.4F16.

N160G80

N170M5

N180G0G28G91Z0.

N190G0G28G91Y0.

N200M30

 

I hope this helps some.

 

Note the line before the G81 line on your example. The Z 6.4.. should not be there, this should be your clearance plane 7.2....
