Hey guy's
I am running in to a problem drilling an angled hole on a 5
axis
machining center running a Fanuc control.
The machine acts like it is losing the tool length off set when
the program tells the machine to rotate the axis 90 along with a
head tip.
The machine runs fine if the rotation on the G68 line is around "I"
axis
and not "J" axis.
The trouble is with the following program if I set the "I" as the rotation
axis
the tool length is read perfectly no problem BUT when the drill
retracts
out in a canned cycle it pulls straight up in "Z" and not like it
should in "X" and "Z" combined
direction resulting in a broken drill.
If I put the axis rotation on the "J" axis the retract looks good but the
tool length off
set is ALL screwed up.
The "X" "Y" & "Z" on the G68 line is the distance from world or
the G54 point
to the workplane setting for the angled holes.
Example:
( T15 )
( 10MM HSS DRILL ) N43 G54 X36.1982 Y0.0 N44 T15 N45 G43.1 Z10. N46 S700 N47 M03 N48 G53 Z0 N49 G90 G00 B15.0 C180.0 N50 G68 X0.0 Y12.331 Z-0.0947 I0 J1 K0 R-15.0 N51 Z4.0 N52 G98 G83 X36.1982 Y0.0 Z-8.045 R0.1 Q0.1 F3.0 M08 N53 Y-1.2656 Z-7.405 N54 G80 M09 N55 G00 Z4. N56 G53 Z0 Any help or example programs would be help full.
Even without a G68 call out line.
