I normally use g54 and cut with tip for Surfaces on a 5 axis table

I was putting some logos on a part the other day

I figured Id program the logo with 3 axis paths and just position the part

So I positioned the part and set my work offset with G58

Figured every time a part needed a logo

I would just use a G58 in the program and it would rotate the A and B axis

It doesnt work that way Unless I call out a A62 B 180

I thought the G58 would turn the rotary's since my offset table The A and B

axis have been set with Part Zero's


What AM i missing ?

Thanks for the help ...

Set the A/B the same way you would set the X/Y at the position you need, but there is no way around programming G90 G58 X0. Y0. A0. B0. so in hindsight A62 B 180 is just as easy. You could make a little sub program that can do this with M98 then you only have to program the A62 B 180 program once.You only add the M98 M99 to the program you need logos on.

I was just confused on why you set A and B in offset table but it doesnt move if you call it out ?


Its not that big a deal I could have programed my part LOL with less typing

so far .. I just figured I was missing something ...

Kojack,

If you loaded A62. B180. into Work Offset Table, as G58 postioning angles, you should only call G0 G58 X## Y## Z## A0 B0 (just as makingchips said) on your code and it should work.
If this is the case, it's programed this way and not working, please post CNC code and we'll analyse it for you.
Cheers!

I can't see you calling A or B in your program. Maybe I'm just missing it!

no your right ...

But I have a G58 in there and my G58 has the rotory where i need it too go ..

look @ my G58 on the offset table

I run the normal program with g54

I wanted to just place my logo program with a different offset G58

figured it would rotate the tables ...

[big_mak]

G58 will just make that work Coordinate active, it will not reposition until you G00/G01 A## B##

[kojack]

G58 will just make that work Coordinate active, it will not reposition until you G00/G01 A## B##

So G58 or G56 wont postion A and B axis unless I call it out

where would you put the B and A move in this Program Can i run it on my
g58 line

I need to go B 208.485 A 62.2

This is how I would write it:

N106 G0 G90 G58 X.2435 Y-.9587 B208.485 A62.2 S12000 M3

However on your offset page under G58 I would have the Rotary axis set the same as the other (G54) coordinates. Mine are set to the B axis face (the one you mount to) planer to the machine table. So if I were to do work on the horizontal (A90) in any work coordinate I would always call out A90. in the program. That way anyone else who programs for the machine can program the same and setup is straight forward.

Alright, now we have your original code, it's quite easy. It's correct that inform G58 only load this information to the machine, but it does NOT command any movement. But, once the coordinates (angles) are informed at Work Offset Screen, you must call A0. (tip: you can type only "A" and the software will complete when you type Write/Enter or Insert) B0. The code will be:

N106 G0 G90 G58 X.2435 Y-.9587 A0. B0. S12000 M3
N108 G43 H6 Z4.
N112 Z.1

My inputs are bold. I use to call all 4 axis positioning at the same block (only exception to Z axis), but you need to check if there's enough space for it at the first time you run the program.
Please, note that I've replaced the second G58 for G43, and this is the most worrying point, cause it may crash the machine.

I hope it can be useful. Once more, thank you all for choosing Haas Automation!!

[big_mak]

I used to run a horizontal, and we did our table indexing before while the machine is at Z home for safety sake, that's why I had the A/B moves on a separate line. Just a safety. As long as it is after the G58 call you will be alright!
