help with G50 programming on a takisawa tp 3 lathe pls.

hi i am very frustrated.
i have been at this for two dsys and made little progress towards understanding .
if somebody could post a sample program id be very grateful.

his is what i have so far

g28 u0w0
G0 U-2. W-10.
G50 X9.4328 Z8.4760
G50 T0700 S800

<FACING OD ROUGHING CYCLE>

G0X9.4328 Z8.4760 T0700
G0 U0 W0
XXXXXXXXXXXXXXXXXXstuck here

TAKISAWA TP 3 is the machine and fanuc 0 i think
IF someone can give a detail explanation on how to do next tool offsets would help also

Hello qrovin,
You really need to determine the model of the control and Post here for meaningful help. If its an Oi control, its unlikely that it doesn't have Geometry Offset Programming, and therefore, G50 won't be required to set the Coordinate System for each tool. However, if G50 is the only method available with your control, each and every tool will have to have a Coordinate System set for it with G50.

With regards to your program example, if the X/Z G50 for all other tools was established in the same manner as your Tool T07, then returning the current tool to the same coordinate as established by its G50 is correct (one method of doing it). This will return each tool to a position -2.0 and -10.0 from X and Z Reference Return position respectively. Each subsequent tool will then have a corresponding G50 executed from that position.

The G0 U0 W0 Block in your above example is irrelevant, as its commanding the control to move the X and Z slide Zero Distance from the position (current) established in the previous block.

Regards,

Bill

first of all thank you guys

so the next tools i have to take a cut on od and measure . that far i understand . this is where im still stuck .the next step is to add that diameter to which number?absolute , relative , on the geometry table?

so if say the diameter of the part after skin pass is .5 and relative value for U IS -8.1234 AND ABSOLUTE VALUE IS x 1.0000 ? what do i put on the g50 x?

i have been trying to find what fanuc version this is but i maybe just blind. its takisawa tp 3 1984 year made in japan

Do some searching here on the site. Probably more examples then you can shake a stick at. Then post what you have or having trouble with.
