MACHINING PROGRAM

Hole position data (X, Y)
Set hole positions using incremental or absolute data.
Hole-machining data
Z .... Set the distance from R-point to the hole bottom using incremental data, or set the
position of the hole bottom using absolute data.
Q ... Set this address code using incremental data. (This address code has different
uses according to the type of hole-machining mode selected.)
R ... Set the distance from the initial point of machining to R-point using incremental
data, or set the position of R-point using absolute data.
P.... Set the desired time or the number of spindle revolutions, for dwell at the hole
bottom.
(Set the overlapping length for the chamfering cutter cycles G71.1 and G72.1.)
D ... Set this address code using incremental data. (This address code has different
uses according to the type of hole-machining mode selected.)
K.... Set this address code using incremental data.
(This address code has different uses according to the type of hole-machining
mode selected.)
I ..... Set the feed override distance for the tool to be decelerated during the last cutting
operation of drilling with a G73, G82, or G83 command code.
J(B) ... For G74 or G84, set the timing of dwell data output; for G75, G76, or G87, set
the timing of M3 and M4 output, or; for G73, G82, or G83, set the feed override
ratio for deceleration during the last cutting operation.
E.... Set a cutting feed rate (for G77, G79 and G85).
H ... Select synchronous/asynchronous tapping cycle and set the return speed override
during a synchronous tapping cycle.
F .... Set a cutting feed rate.
Repeat times (L)
If no data is set for L, it will be regarded as equal to 1.
If L is set equal to 0, hole-machining will not occur; hole-machining data will only be
stored into the memory.
