We have a sinumerik controller 840D in quickjet machine.

i'm trying to make modal call of G83 cycle.

the problem is in positioning, machine is moving in at cut speed 50 mm/min quite slow.

how can i solve this?
thanks

You should use the G0 command for positioning. If this don't work, why don't you use the Cycle83 command. you must call the first position with mcall Cycle83(...), at the end of the cycles you must call mcall again.

When you program the G291 command you can program in Fanuc language on the Siemens control, in the left upper corner stays ISO (Deselect=G290)

drilling example :

T8 ;Drill D4
N2 M6
N6 S2600 M3
N10 G0 G90 G54 G64 X-27 Y-10 Z5. M07
N14 G291 ;Fanuc language
N18 G81 G99 Z-45. R5. F450.
N19 X-35 Y-20
N20 X-45
......
N22 G80
N26 G290 ;Back to Siemens language

from here you can use cycle81 again or any Siemens cycle...
This also works fine if you use a fanuc post processor for a Siemens control
just make sure the post write G291 at the beginning of a drilling cycle and G290 at the end of it....
