8055 and pre-selecting the tool

[makela]

Hi everyone. This could be very simple question but; how do i pre-select next tool with machining centre? If I put T6 twice to the program, the magazin starts spinning around and I need to reboot the machine. Only rebooting stops magazine.

If i put only one T6 just before M6, the machine has to wait until next tool is on the right position. If the T6 is couple of lines up, and I have to stop program for some reason, continuing is rather difficult.

Is there some kind of call that the machine keeps looking code forward or how should it be?

like this:
...
G1 X150
T6 ; pre-select here for example
Y60
X0
G0 Z3
M5 M9
T6 ; Magazine starts spinning around becouse of second T6-call
M6
G0....etc..
....

(Hope that somebody understood what I'm asking for. )

Thanks. At the first look I didn't find solution. (I'm not very familiar with english.) I'll keep on looking for.

Maybe this is a dumb question on my part, but why would you want to "Preload" the next tool?

When changing a tool you need to drop off the old one prior to picking up the next one. On some of the machines that I have seen with High Speed Tool Changers, there was code at the begining of the program that set the order of the tools so the next tool was automatically "Prestagged". Others I have seen there was a specific M code that you had just after a tool change that "Prestagged" the nest tool. Are you doing this because of a High Speed Tool Changer?

That's new to me.

It's not so high speed. It's very slow, and if the tool is not preloaded, it takes too much time when the magazine finds right tool. It should preload next tool during the previous tool is working.

There is 24-tools in the magazine. I'm not sure but I think it's called umbrella-type magazine. And it's slow. So am I , please ask more if I cant explain.
