Fixture offsets ......

[TOOLZNTHINGS]

Hi All,

Could someone post a step by step procedure for setting more than one fixture offset. After picking up one part in a vise and setting zero ( G54 ), what do I do for setting G55 on the next part. Not seeing the necessary steps.

Thanks in advance !

...one way to do it is using G10L2P Command
G Codes

The absolutely simplest way:

First:

G54

Move and reference zero for part 1.

Then:

G55

Move and reference other zero.

You could then copy-and-paste the inner part of the program (if the part is the same,) or the second half of the program (if you're doing top/bottom,) making it go to G54 the first time (simply by running G54) and the go to G55 the second time (by running G55.)
Beware that the "safe line" in the program code you copy may include G54, which you'll have to remove or change go G55 as appropriate.

Then your program will look like:

G54
(youre now back in the G54 coordinate space)
G0 X0 Y0 Z4
(goes back to starting position in G54)

(then your part code goes here)

G55
(youre now in the G55 space)
G0 X0 Y0 Z4
(goes to starting position in G55)

(then your other part code goes here)

The easy way is to call G54 then find the point of origin for the part (X0Y0). NOW move to the point of origin of the second part . Look at the X/Y dros that is the fixture offset values . Go to the setting/work offset page and type in the X Y values in the G55 line.

To test if you got it right. G54 X0Y0 should take you to the first part point of origin . Then G55 X0Y0 will take you to the second part point of origin.

Got it ! Thanks to you both ! Missing the MDI part and understand the second method,too.
