Post issue, lathe spindle direction wrong

[specv]

I am tweaking my post for live tooling on an old lathe. I am getting an M4 spindle rotation on when machining on the face, but an M3 when machining on the periphery of the part. Both should be M3, as they are stated as CW the ops manager.

 

TIA

Have you checked the settings in the Machine Definintion?

 

Also, what post, machine def, control def, machine type?

 

I'm no "expert", but I'll try to help if I can.

In your post check for the "Machining position turret / spindle settings

 

#Machining position turret/spindle settings

# Switch strings based on turret position top/bottom-left/right and cut type.

# Turret position is based on the Mastercam settings (see lathtype).

# Strings are re-assigned for output in the routine psw_str_mult.

# The string variable sw_string holds the place position value to determine

# how to assign the strings. Planes are relative to the view from Mastercam.

# Assign the 17 digit string following the alpha columns below:

# A - C axis, 1 = axis winds, 2 = axis signed, 3 = indexer

# B - Spindle direction, 0 = normal, 1 = reverse

 

Depending on the turret /spnidle setup you have go to that block and look under the B columns and change it from 0 to 1 or 1 to 0 depending on what you want.

 

#Columns- ABCDEFGH.IJKLMNOPQ #Turret/Spindle #Path Type

scase_tl_c1 10000222.000000000 #Top turret/Left spindle, Turning cut

scase_tl_c2 10000012.000000000 #Top turret/Left spindle, Right Face cut

scase_tl_c_2 10110012.000000000 #Top turret/Left spindle, Left Face cut

 

Hope this helps.

Sorry I wasn't clear on my first post, the live tooling rotation not the "c" axis(chuck) rotation.

 

I am drilling so there is not rotation of the chuck except for indexing and that looks right.

 

it is the Generic Fanuc 4X MT_Lathe.pst that I am modifying.

Snehal, that was it, thank you!
