Polar interpolation on right spindle

[David Colin]

Hi,

We just got a Hwacheon Hitech230 lathe (main+sub spindle) with Fanuc0i control.

I started to program it with MPLMASTER post but i have an issue with polar interpolation on sub-spindle.

I programmed a contour toolpath on left Mastercam plane. My issue is, on the machine, sub-spindle is rotating in the wrong way... Any idea?

Need to go into the Matrix controls for the spindle and make the changes needed.

#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
# C - Plane 0 arc/comp, 0 = normal, 1 = switch

Thank you very much !  I'm going to play with theses settings.
