Machine offsets at begining of program?

[DavidSV]

10 years ago I ran a Mori Seiki SH-50 3 machine pallet pull. I vaguely remember how it functioned. I was just an operator back then. Anyways, when a pallet would get sent to a machine, it would download the program to the machine at that time. There were lines at the beginning of the program that when read would change the offsets in the machine. If you had to make an adjustment for an offset (say you had to shift X .003 for P3) you would change the it at the beginning of the program.

 

Long story short, How would you do that?

[bbarron]

was it done with a G10 line?

G10G90L2P1X240.831Y-397.880Z-673.254B225.0

G10G90L2P2X240.814Y-605.871Z-673.213B225.0

G10G90L2P0X0Y0Z0B0

The P0 line will shift the cordinates like a g52 would.

G10 is the was to do it like bbarron stated. We do this for all our repeat jobs and it works awesome. BTW, we use it in vertical mills since we have pallets systems in all machines that repeat to 0.0002"

No book in front of me but I believe the L varialble desinates which type of offset your setting, L2 being work offsets. The P0 would be g54, p1 g55, and so on. I think you can also offset tool lengths, dia's and such.

---

L2 is Common Offsets (G54-G59)

P0 changes your Common Offset(G53)

P1 Changes G54

...

P6 Changes G59

 

L20 is Extended Offsets (G54.1P1 - P300)

P1 changes G54.1 P1

...

P300 Changes G54.1P300

 

Tool Offsets and parameters can be done as well.

Found this also...

 

(L10 = TOOL LENGTH OFFSETS )

(L11 = TOOL LENGTH WEAR OFFSETS )

(L12 = TOOL DIAMETER OFFSETS )

(L13 = TOOl DIAMETER WEAR OFFSETS )

(P1 = H1 - H WEAR 1 - D1 - D WEAR 1 )

(P2 = H2... ETC )

(R = VALUE )

)

(SAMPLE USES POSITIVE TOOL LENGTHS = )

(DISTANCE BETWEEN FACE OF SPINDLE... )

(... AND TIP OF TOOL )

G10G90L10P6R2.7254

G11 (END WRITING PARAMETERS)
