HELP FOR OPTIMISE TOOL CHANGE

[POOR ENGLISH]

NEED HELP!

WE HAVE A VERTICAL TURNING CENTER TOSHIBA TUE-20
WITH A FANUC SERIE 18T CONTROL

EACH TIME WE MADE A TOOL CHANGE THE MACHINE MOVE TO THE REF.POINT
AND AFTER SHE MOVE IN Z AND X EQUAL TO THE VALUE OF THE OFFSET OF THE TOOL.

I WANT TO KNOW IF IT'S POSSIBLE TO REMOVE THIS 2 MOVES THAT TAKE TIME AND WEAR THE SLIDE UNNESSARY.

THIS IS THE PROGRAM FOR TOOL CHANGE;

G04X0-----I DON'T KNOW WHY?
M05
G28W0-----THIS IS HERE THE MACHINE MOVE EQUAL TO Z OFFSET
G28U0------THIS IS HERE THE MACHINE MOVE EQUAL TO X OFFSET

The G04 X line is added sometimes to dwell for a short time when using slower controls that need register ready signals. With the X value being 0 there is no dwell so it is not slowing anything down. I would just leave that alone.

The G28W0 and G28U0 lines are probably in place to move to a safe place prior to changing tools so there is no crash. These can be made into comments so they will be ignored by simply place brackets around them: (G28W0) and (G28U0). This way the control will skip them, but you can leave them in in case you want to use it in the future to avoid chuck fixturing or something else.

G28W0 and G28U0 you marked are before the tool change. They command going to machine zero in Z and then X for the tool change.

What are M63, M64, M65, M66, and M67 doing? Along with all the moves prior to the G28W0 and G28U0 at the very end (I think you mean these are where it moves by the offset amount).
