Alen Bradley control & G83

[Ashan]

please someone give me a sample

program for G83 deep hole Drilling canned cycle

The Control is Allen bradley 8200 series

 

for Fanuc

G83 G98 Z-3. R.1 Q.5 F3.0

 

I do not understand what is the format of Q or any other Letters or pecking

 

Thanks

[mayday]

G83 is peck with full retract to R plane

G73 is peck with a chip break, the retract amount is based on control param gerenally .005 to .05

Q is peck amount for G83 & G73

R is rapid height before drilling feed rate

G98, G99 is Z rapid pos between holes. either at R plane or initial height

[Ashan]

I tried Q gives format error

Such as

G83Z-6.R.1 Q.4 F3.

Dont you have the Manual for the control? Or possibly some programs already in the machine (I never trust the manuals)? This is some sample code from a retrofit AB8600. The problem is the builder can do what ever he wants. So, there are no standards for AB drilling cycles.

 

This uses some kind of IJK format

I first peck

J second peck

K possibly return clearance amount?

I have manual but there is no details about drilling cycles

I just made a longhand subpro to do this job now

Thanks

Ashan,

 

On some controllers the "Q" needs to be programmed without the decimal. IE: for 3/8 program Q37500 or Q3750 The "P" could be the same too.

Thanks I try this again

Isn't there a "help" page somewhere in the control that lists what variables do what?

Allen Bradley was never very user friendly. I'll bet you wont find and built in help. The closest they ever got to a friendly control, was to buy the Bandit Control line and then drive that company into the ground.

 

Greg: Your right about those codes, but those aren't from the AB 8200. AB is one of those wild cats like Siemens. Gotta reinvent the wheel just because they can .

 

Without the control manual or the doc's from the machine builder, it's going to be trial and error for some of the cycles.

IT was F---ing K

Ashan,

 

What do you mean?

Did you need to use K not Q in the cycle? With or without decimal?

[Ashan]

K without decimal
