Hello,
We recently acquired 2001 Citizen L20, and I noticed something unusual when programming. When calling out T21-T23 for face drilling, for some reason my Y1 moves in Sync with X2.
The program is something like this:
G821
T2100
G0Z-.04
M140
G0Z-.040T21
...
...
G0Z-.040T00
M141
G820
Is it normal for Y1 to move in sync with X2? Is there anyway to program so it doesn't do that?
I don't have a lot of experience on Citizen Swiss, mostly on Nomuras, and Tsugamis.
Thanks in advance.
When you go into G821, your gang slide should escape to a safe position as your sub moves your 20s tool into position. Your gang should park itself with tool 1 over the stock and about 3-5" above the stock. Once your gang is parked in the safe position it should NOT be moving while your 20s tools are working.
That said, all my experience has been with newer L machines that use G610 instead of G821. Per the Citizen manual, the two modes are the same except that G610 automatically positions your sub in Z (no need for M140). From the handbook: "This (G610) replaces the L51620's G821 command because G610 works deeply with the first T2x00 call to move Z2 in while changing the mode."
Short answer, no Y1 should not be synced with X2.
On the L320 the Y1 axis is synced with the X2 axis . This is normal condition on this machine.
G821- Machining mode change to use the three drill stations T21-T23 in the
$1 programming line. G821 will queue with lines $1-$2 then G821 makes
the Y1 axis follow the X2 axis so you don't hit the turning tools. All
programming is done in $1 and $2 must wait on G820.
You can also use an R1 to make G821 not sync. Y1to X2 for special applications.
Example...
$1 $2
G821R1 G821($1 takes control of T21-T23)
T2200(Center)
M3S1=3000
G0Z-.05T22
M140
G1Z.1F.002
G0Z-.05
