Re-Chucking on Tornos EvoDeco 20

Hello all,

I am new to CNC Swiss machines and we have a Tornos EvoDeco 20. The TB Deco programming software is not the most user-friendly software that I've used, and we are having a hard time trying to re-chuck during an operation so that we can machine parts longer than 200mm. Can anyone help point me in the right direction for re-chucking information.
I am also looking for any general resources for TB Deco and Tornos. There does not seem to be a lot of information available on the internet. Any help would be greatly appreciated.

Thanks,

hello, if i get it right, there is "thing" with your actual programing method and/or machine, that does not allow you to machine such long parts

have you tried to g-code it ?

unfortunately, i can't help you with a nice code example, because i don't have such a machine, but i will give you pseudocode : thus create a simle program, that will do this :
... spindle 1 clamp
... Z1 advance +50mm
... spindle 1 unclamp
... Z1 advance -50mm ( going back, like nothing happened )

now loop it :) this code, should keep on going, until bar gets short :) once this "basic" thing works, you may add cutting operations over it

if you know the codes for your machine, you should deliver that behaviour in a few minutes ... try talking with your local dealer / kindly :)

Thanks,
The Tornos machines have specialized programming software called TB Deco, and it has strange formatting that requires you to insert the g-code in specific areas, or compartments. I think that your process is the way to go, so now I just need to figure out where it goes.
We have some training on this machine in a couple of weeks, so I should figure it out then. I was just trying to do a long part before they came.

Im trying to remember my brief stint programming Deco20's

I think it went something like
Park sub in front of main, feed bar out, clamp sub on part, sub remains parked.
Open main collet
retract main spindle (i think I used just a G0 Z0 or something like that)
clamp main collet
reset coordinate system (I think TBdeco's crappy language used G53 like G53 Z-(amount that was rechucked, but I forget if the Z was + or -.)
unclamp sub
move sub out of way

TB Deco's language definitely takes a while to get used to. Your method is basically what we ended up with, and now I have a template that I just use for all my long parts.

hello, reading the latest posts, i remembered how i was teached to program the gang lathe : i received a program with dual spindles, part transfer, few operations on both spindles, part-catcher + feeder macro; each phase was written with minimal code, nothing extra, only the basics

i was looking at it like "what is this ?" it took me a few days to "merge" with it, but, after that, i started developing from it, so to create a "template" :)

i really have no clue about that tb language, but i agree : 2 similar machines from 2 different brands, will move and deliver same part in almost same time, but you need to shift your head between the controllers : each one does things in it's own way ... is not like when switching cars, or beers :) i have seen controllers requiring a signifiant different amount of keystrokes, fpr doing the same thing

.. and there is another thing : if a controoler is not explained well, one may end up doing things mecanically : for example, to achive this, i have to push this buttons, but i have no clue what exactly i am doing / i have seen this; like a mortal combat fatality keys combination : you press and look at the screen : did someting happened ? if not, then i have to change the tempo, because i am sure that keys where pressed in the correct order ... whatever / kindly :)

If needed, i have a sample for a long part program. Never used it but given by a Tornos Tech.

Hello , please do you have a sample for long part?
Thank you Martin
