Did you get the 300 series diagnostic bits to tell the brain what kind of machine you have - 10/12 station turret, live tooling/not, tailstock/subspindle, like that?

G74 is not just for drilling. I have used it to break up chips in rough boring, face grooving, etc. If Havemann's problem is long, stringy chips wadding up inside the bore, another solution to...

Could you do your ID roughing using the G74 "woodpecker" cycle to break up the chips and eliminate operator interaction?
Just a thought.....

OD's:
600-800 surface feet
.060 depth of cut
.015 feed per rev

ID's:

I love your use of G65 as a branch jump. I can see how you would be able to, say, change some variables and then jump back to repeat N123 or go anywhere else as a sub, all within the same program. ...

Try this:
G97 S200 M03

I don't know how much you know about how the bits are numbered, so why not start from the beginning.
The bits are named 0 through 7 for a total of eight bits.
0 is the name of the farthest bit to...

I'm willing to bet that procedure sets a 1 at diagnostics #305.0 --

Check diagnostics page # 305.0 (that is the farthest bit to the right)
Without this set to 1, you will lose rapid traverse after EDIT

On the conquest, you hold zero return button and push turret index button. Turret will turn to station #1 and lock. I imagine yours is similar.

I found out - it's diag. #19.7

The only way I can see you doing this is to start your cut at the chuck, and work out. The only problem is that each plunging cut at the chuck end will be at roughing speed.
Have you thought about...

Hardinge Conquest 42, Fanuc OT-B control. Whenever I power up, it demands a turret return. No big deal, until lately the turret just spins forever. I stop it, line it up on #1 by hand, lock it...

Don't worry about it. There are formulas for all that crap, but just use what you have lying around. Turning to a precise diameter first is not necessary, just push the knurls in until...

610 RPM
0.006 ipr infeed to depth (probably about 0.035)
0.012-0.015 feed towards chuck - don't dwell

You can repeat a time or two if you need to, in order to raise the knurl to a good height,...

Try cocking your knurl rollers so they are more or less cutting on the front edge, rather than trying to shove the entire width into the piece. Then feed back and forth to get the width you need. ...

Did you crash the machine and need to reset the torque limiter breakaway?

There are some things you just can't explain. I don't know what was stuck in that circuit, or why I decided to short that line, I just seem to have some kind of ability to go right to where...

Thanks to all for your help. The machine is back up and running. All sensors and switches were working normally. It was just stuck on m, s, t fin signal. Basically I jump-started it with a bent...

The only thing I did was to add the lines for the G74 functions instead of G01.
Otherwise it is the 9135 that came with the machine. Hardinge Conquest 42.
Sucks to get old, huh? Everything hurts...

Thanks, andy, you never know - could be something like that. I will look at all the switches, worn wiring, etc. My diagnostic 700.0, which is the m, s, t complete signal, does change from 0 to 1 and...

Your fingers must have been a blur - lol.

No, Stevo, it is not a mechanical problem. The machine was running, making parts, and it just began to hang up on a M03 call. I found that tool change commands hang it up the same way. So M...

Macros are certainly fun, what with nested loops and levels of calls, but the one thing that is hard to keep in mind - customers don't pay for pretty programs, they want parts. Sometimes you get so...

Thanks, guys
andy, you are sort of on the right track, the machine is looking for an "I'm done" signal, but it is not a mechanical problem. jdeere, you took it a little further, and guhl, your info...

Hardinge also wrote a nifty macro - 9135 - that will drill to a depth of 3x dia and then decrement depth until it locks on a minimum depth increment. They also have a G74 chip breaking routine, but...

Thanks, jdeere, but it is not a drive problem, it is in the controller. RPMs indicate ok on screen. It turns out that M-codes and T-codes make the brain hang up. The program will not step on after...
