System information

SECTION FOUR - PREPARATORY FUNCTIONS (G CODES)
Note 4: Specify drilling data in the block where drilling is performed. Entries (V, Q, B,
Z, R, F, or P) are stored as modal data.
Drill Example:
G90
X6 (drill hole at X6)
G81 G0 R.1 Z-2 F10 (drill clearance .1, depth -2, Z feed 10)
X1 (drill hole -2 deep at X1)
X2.5 F5 (drill hole -2 deep at X2.5, Z feed 5)
X3.5 Z-1 (drill hole at X3.5 -1 deep)
Z2 (rapid Z to +2 to clear clamp)
X7 Z-2 (Drill hole at X7 -2 deep)
G80 (cancels drill cycle)
Note 5: If when using G76, G78, G86, G87 and G88 the distance between holes is tool
small, a dwell (G04) needs to be inserted between moves to give the spindle time
to reverse directions.
