Bar puller using Acramatic 850 on a 1986 Cinturn 208U

[67Charger]

I got a small job turning some weld-in weights for clutch pressure plates and have been having issues getting the machine to play nice. I'm finally to the point of testing my program, but now I have found one more
issue. After the cutting operations (turning and parting), I stop the spindle
and coolant with an M5, change to the bar puller, feed it on, M80 to open the
chuck, then... ...nothing. It won't retract the turret along the Z axis to
pull more material out. It says initialize chuck jaws. Is that not the right
method? I was going to retract, M81 to close the jaws, then retract more to
pull off the bar.


Any help you could give me would be appreciated, these parts are already
overdue. I've been feeding them one by one to get through the job, but this is getting rediculous.

Can you post the code?

Are you in FPR or FPM?

[67Charger]

I'm at home, so the code will have to wait until tomorrow.

I'm in FPM. As soon as it executes the G80 and opens the jaws, it should execute a G1Z1.$ at F10, but it gives me an alert saying initialize chuck jaws and freezes.

Are you keeping the door closed? It's been awhile since I've done a barfeed on a Cinci.

[67Charger]

yes, and for the sake of semantics, I am using a puller in tool position #4, not a feeder.

Thanks!

I wonder if you need a dwell between opening the jaws & feeding. Give the chuck a couple seconds to open. Sorry I couldn't be more help.

[67Charger]

Actually, that's not a bad thought.

[Technical Ted]

It may help if the chuck has switches for the open & close positions. Post the code tomorrow if you can't get it to work.

Any luck?

Since I only had to do 200 parts, I pulled it by hand. My replacement puller collet has not shown up yet, so I ran the parts without it. Now that the deadline is gone, Monday I'll try the dwell and see if it makes the difference.

Here is the whole program.

How would I edit this to add dwell time using the 850's G04 Dwell command?

I have an Acramatic 900 manual at work, I'll bring it home tonite. I'm prety sure most of the 900 & 850 codes were the same.

G04 sounds right & you'll need the code for how long to dwell. It might be G04 S4 for a 4 second dwell.
