G54-59 help please

[batmill]

We use conversational with our new Hurco, but just started with CAD-CAM, and send this via a pc. We're unfamiliar with nc code, and need to edit to perform 3 offsets and the original workpiece, which is set at x0y0.

Would this work: T6 etc.
GO1 G54 X0Y0Z2.0

SUB (main) PGM.

G55 X100 Y0
M98
G56 X200 Y0
M98
G57 X300 Y0
M98
M25

I would only appreciate a simple format as I will not be using G codes that often, and I'm just a stupid old miller!

Many thanks in anticipation.

Do you mean you want to perform the CAM program at three different locations?

Yes, using the offsets: G54-G59, I'm just not sure about the formatting of these - how to place and arrange them in the correct order.

Thanks, Barry.

In your example, it appears each part is offset 100 to the right from the previous part.

The work offsets would contain the X0 Y0 for each part.

O1000 (MAIN PROGRAM)

G00 G54 X0 Y0 Z2.
M98 P1001 (CALL SUB)

G00 G55 X0 Y0
M98 P1001 (CALL SUB)

G00 G56 X0 Y0
M98 P1001 (CALL SUB)

G00 G57 X0 Y0
M98 P1001 (CALL SUB)

M30

O1001 (SUB)
...
...
...
M99

dcoupar, thanks for reply. I've never had to use nc coding before, so please bear with me: exactly what denotes the work-offset of x100 y0 - is it P1001 ?
It doesn't appear obvious to a beginnerer like me where this information is placed.
Also, does the first offset-G54 have to be placed near the start ?

Many thanks, Barry.

Batmill,

When you change the editor over to NC, there will be a work offset softkey when you are in input mode. This is where you enter the data for the G54, G55, etc. It is the same as in conversational. The values are distances from machine zero. When you call up G55X0Y0, the zero becomes the value defined under this softkey. Hope this helps you out. My Hurcology is a little rusty.

When you start up your program, you will need to issue some safty lines and then the G54. Here is an example from our code...

M1(DRILL IN & TOP PORT)
G0G15G17G40G80
G90G94G98
T1M6(11/16 DRILL)
B0.
M98P1100
S4500M3
G54X0Y0M8
G43Z5.H1T2
G83Z-1.24R0Q.5F20.
G54.1P2X0Y0
G80G0Z2.
B270.
M98P1100
Blah Blah Blah.......
