G53T00z0.0

[maximusek]

I know the meaning of g53z0.0 but I have no idea what T00 in this line means. Thank You for any answer...

Is this on a lathe? On some machines T00 will cancel the tool offset.

It is not necessary though because G53 ignores offsets.

The Machine, we're talking about is a swiss. I'm asking because I try to learn something and I know the guy who wrote the program is real pro, so he did it for some reason :-).

Geof is something of a real pro also. We use the G53 to send the turret to a safe index position, such as G53X-8.Z-16., on an SL-35 Mori Seiki. I've got no idea why your pro is using T00. Does the machine require a tool offset cancel before calling up the next tool?

It's swiss screw machine. I use g53zo.0 to send a head home but never with T00. When I must touch the tool off, I call it using T0400 (tool 4 without offset). Machine doesn't reguire tool cancelation.

The T00 is probably something that was needed in an older control and is not necessary now. It probably neither helps or hurts.

it seems to me, by using G53T00Z0, I'm able to send any head (I have 3 in my swiss) home without taking care, what tool is active; very useful in macros.

This is just in my experience, and may not work the same on your machine. We also use the "T0000" in our programming to cancel a tools offset when sending it home,(G30U0W0T0 Our machines don't need the T0, but our programmer is old school and like JWK42 said, it doesn't hurt anything. UNLESS, for some reason you have a large wear offset in that tool. If I had positive 3 inches in my Z wear offset and ran my path, at the end when it reads my G30U0W0T0; line,it will rapid in (Z-) that 3 inches, then go to the tool change position. Which we all know could be (and probably would be) very bad. Like I said, this is what happens on my lathes and may not be an issue on other machines.
