hi

i have a NCT TMC 40V machine center with FANUC 15 MA i lost parameters, i extracted manual from tape and i put in also by hand but when i want to use rigid tapping cycle i get an alarm:

ex 24: machine is abnormal condition on rigid mode and is canceled by M30 OR M40.

if someone knows what parameters should i set cause i am sure these parameters where not on the tape and i do not know .

Thanks fro your help

HAVE A GOOD DAY!

ridgid tapping is an option. The parameter is 9122 bit 4. If that does not solve the problem, I can't help.

HI M8

i know this is already activated is all about that the machine get in position but the spindle do not start to rotate just wait some seconds than i get the alarm.

so the cycle is activated but is just a no corespondence for the rigid tapping cycle between z axes and spindle from parameters.

EX is typically a MTB alarm and you will have to find the definition in their manual. Can you post the code so we can look at it to see if maybe it is a syntax error.

Maybe the attached .PDF will help.

I had problems setting the 5600, 5700 and 5800 series parameters on my 15-MA.

My Parameter #9122 option bit 4 is set so I don't know if that will help either.

I had to follow the parameter setting of machines like mine for this option.

My problem with it, is that the Spindle servo connected through the amplifier A06B-6059-H002 does not accel/decel like it should, although it does work and it is fairly smooth..

Thanks for the PDF, FrankCNC.

I'll check this against my setup. My parameters were hand entered because the machine is a custom built machine.

My last rigid tapping experience with the 15-MA was doing some 1/4-20, 5/16-18 and 3/8-16 taps into some 1018 steel, hich was about 1/2" (0.500" or abt. 12 or 13mm for you metric folks.

They were Reiff & Nestor HSS H3 class taps. I don't remember the speed or feedrate.. but I tried to keep my setup rigid as possible. These were not blind tapped threads. I tried my Hanson Whitney taps but one broke before on the spindle reverse. I did remember though that the fit seemed about 75% so it was pretty good when i checked it with my gage. They werent really even critical but I wanted to be sure so I checked them anyhow both with the actual fasteners used and the gage.

Now that I think about it, the spindle speed was about 300-500RPM but still cant recall the feed.

yeah before lose parameters i used the G84.2 comand so is something about the special parameters

the g84 i can use but g84.2 not so maybe somedoby use this special function\

[sinha_nsit]

For rigid tapping, you either use M29/G84 combination, or just G84.2.
For G84, you can also select between standard mode and rigid mode through a parameter.

[FrankCNC]

This works on my 15MA, if using G94 the feed rate F is in mm/min, if using G95 the feed rate F is tap pitch, no need to code in M3 (M4 for G84.3 Left hand tap) as rigid tap cycle starts the spindle itself.

ok thamk you m8 i will give it a try and let u know about it

thanks again for u help!

[gbowne1]

Thanks for the G code there FrankCNC. I've been searching for ways to implement this in my 15-MA.

My usual part rigid tapping program at the start was to go from the machine zero home to the zero of the work offset of my Kurt D675 Vise on the center of my custom built VMC's table.

This part I did with different tap sizes went pretty smoothly, it' just that the servos may need a little tuning because of age, but they were recently certified and recertified to meet its standards per the manual.

I did not use M3 although I could have.

I used G95 too.

i have victor 10ma machine but spendle is not work as requirt only 4-5 rpm give when i give 1500-5000rpm please help me thanks:
