Ridgid Tapping on Okuma MB-56VA

HI all, My mahcine is Okuma MB-56VA OSP-100M
now Been using it for over 5 years and its all good.
however when it comes to ridgid tapping I want to Peck ridgid tapping
the mahcine will peck
if I write this:

G83 X0 y0 R2. Z-30. (this will ridgid tap all the way down non stop)
however if I want to ridgid peck tap to z-30
then i have to put

G83 x0 Y0 R2.0 Z-10.
G83 Z-20
G83 Z-30
this will peck to z-30 no problems..
so My Question is I dont want to write G83 everytime infront of Z
so i want it to look like this:

G83 x0 Y0 R2.0 Z-10
Z-20.
Z-30.
is there a parrameter that can control the Z movment to peck like this?
bassically if i run it without the G83 infront of the Z- then it will ignore the numbers and only go to z-10. which is the only the first line..
anyone know whats the paramerts for the ridgid tapping cycles?

thanks

Query:- G83..... what M-code do you use for peck drilling with full retracts ??

I think your #3 & #4 buttons on the keyboard have been swapped over.

The G-code is "modal", meaning it is active until changed by another G-code from the same group

ie G0, G1, G2, G3 are in one group
G17, G18, G19 are in another. A code from one group will not alter another code from a different group

So, there is no parameter to alter, just state the code on the 1st peck ( hole ), then do the pecks for that hole----you could put the pecks into a subroutine after the M30 if you had many holes to tap & use a call statement----remember to re-state the 1st peck level as all the addresses within the cycle are modal as well

ie

Code:

---

G95 G84 X0 Y0 R2.0 Z-10. F2.0
CALL OPECK
X10. Y0. Z-10. ( next hole, must specify the 1st peck level again)
CALL OPECK
G80 G94
...
M30
()
OPECK (Tapping Pecks)  <-- yes, you can put comments here, they do help
Z-20.
Z-30.
RTS
%

---

G95 is feed per rev, so the feedrate is the lead/pitch of the tap ( saves remembering to alter the feedrate if you do change the programmed RPM )
---also look to see if you have the G284 function - also a rigid tap cycle

hi, and thanks for repling.
my peck drilling cycle is:
N4 G83 X0. Y0.0 Z-70.1 R5.0 Q5.000000 F60.0 M54

you are right, my Ridgid tap cycle is G84...
but my problem is that if I use
G84 x0 z0 z-10
z-20
z-30
.
.
then the cycle will ignore the Z-20 and Z-30 and only will read the Z-10..
and not Peck, but if I put G84 infront of it then it will peck..
should be able to just put the number there without me using G84 all the time..right? but it wont, so i though there might ba parameter that can control the behavior of the G84 cycle somewhere..

thanks.

On our P200M control peck tapping is G282

G95 G282 X0 Y0 Z-30 R2 Q10 F2 S400 M53

I found that
N4 G282 X-120.0 Y0.0 Z-10.0 R2.0 Q2.0 F800.0 M54
is doing pecking and it seems to reverse the spindle on going up, however I couldnt see
if it was real ridgid tapping or not due i did it in air, so not sure if its going to
break in metal or not...

The spec sheet I have calls for an S code in the G282 block.
G282 is Rigid tapping. Why wouldn't it be as stated.
Don't be scared. Try it ;)

hi, i have a question about that machine and the rigid tapping function of it. is there a delay at the start of every hole to tap on that specific machine?

yes you can delaye it by G code:
G04 P15 (for 15 seconds)

i started a new thread for that topic. http://www.cnczone.com/forums/okuma/...a-tapping.html
