Chip break drilling on Haas St-30

[Odin]

We are trying to Chip break on our Haas ST-30 and when we run the program it will not chip break, it does a full retract peck drilling cycle. It posts the "G83" Prck drill cycle. I looked in the post itself and the chip break and the peck drill cycle both are "G83" . Anybody have a clue on how to chip break with this machine? TIA

Will it drill correctly if you manually edit the G83 to G73?

[Odin]

Nope. We tried that also. It threw a error. Also tried adjusting setting 22 in the control... nothing. I'll look and see what error it was. Thx

[Odin]

When we change G83 to G73, it throws alarm 315 ( Invalid P code in M97,M98,or M99).

I am not familiar with your machine at all....

Is the drilling in a subprogram?

for chip break i get this:

 

 

( #2 CENTERDRILL TOOL - 3 DIA. OFF. - 3 LEN. - 3 DIA. - .1875 )

T3 M6

G0 G90 G54 X-3.3125 Y3.2476 S2000 M3

G43 H3 Z.1

M8

G98 G73 Z-.875 R.1 Q.03 F5.

G80

Im not familiar with it either. Im not quite sure if its a sub or not. We cant even figure out how to get into the O9999 nunbers.

from the manual:

setting 22 Can Cycle Delta Z

 

This setting specifies the distance the Z-axis is retracted to clear chips during a G73 canned cycle. The range

is 0.0 to 29.9999 inches (0-760 mm).

 

 

G73 Irregular Path Stock Removal Cycle (Group 00)

D Number of cutting passes, positive number

* F Feed rate to use throughout G73 PQ block

I X-axis distance and direction from first cut to last, radius

K Z-axis distance and direction from first cut to last

P Starting Block number of path to rough

Q Ending Block number of path to rough

* S Spindle speed to use throughout G73 PQ block

* T Tool and offset to use throughout G73 PQ block

* U X-axis size and direction of G73 finish allowance, diameter

* W Z-axis size and direction of G73 finish allowance

 

I do not see where this could be used for chip break cycle.

 

I think G74 may be what you are looking for, but I have not used.
