Just interfaced a different bar feed to my lathe, and have no experience programming this type. Lathe is a Doosan Lynx 220 LMSA, and the barfeed is an Iemca Vip80-E. Does anyone have some sample code I could see to accomplish a barfeed to a stock stop (not sub-spindle pull)? Maybe also explain how to set the parameters on the barfeed itself?

Thanks!

Hi

Never set up an IEMCA BUT, as far as programming goes..

Something like this:

EXAMPLE ONLY
G97G99F.004S2000T1010M3P11(PART OFF TOOL)
X1.875Z-1.
M10(PART CATCHER UP)
G1X0(PART OFF)
G4U1.(DWELL)
G0X1.875M11(PART CATCHER DOWN)
Z8.M9
G98F40.T1212M5P11(STOCK STOP)
X0Z-.99M31(INTERLOCK BYPASS)
M69(CHUCK OPEN)
G1Z.01(FEED OUT)
G4U.5(DWELL)
M68(CHUCK CLOSE)
G4U.5(DWELL)
W.062(RELIEF)
G0G99X6.Z15.(SAFE POSITION)
M30(END)

im learning to do bar feed with the Lynx 220lma and have an MTI V-65 E bar feeder. heres a bit o programing ive been working on so far.

( write this code into the start of your part prog:

M98 P9998 (BAR FEED PROG Z.020)
N1000 (REF POINT OF PROG TO RETURN TO FOR BAR RELOAD PROG)

%
:O9998(BAR ADVANCE)
G0 G40 G80 G99 G54
T0121 (TURRET STOP)
G0 Z5.0 X0
G0 Z2.0
G0 Z.020
/2 M98 P8000 (NEW BAR IF NO STOCK)
M31 (CHUCK MODE ACTIVE)
M69 (CHUCK OPEN)
M51 (BAR FEED)
G4 P100
M68 (CHUCK CLOSE)
G0 Z5.0
G28 U0 W0
M30
%

The bar reload is very similar in coding but as with the above prog it calls for a sub prog O8000 . I dont have this sub prog on hand currently but from what i remember there is a parts catcher code before bar feed to catch the remnant, open the chuck, barfeed M51, dwell, M11 (parts catcher in,) turret stop, end prog.

i am still getting the bugs worked out of this program, but hope some of this helps.
