System information
SECTION FOUR - PREPARATORY FUNCTIONS (G CODES)
Initial Level and Point R Level
The drilling data is specified following G73,G74,G76,G77,G78, G81 to G89. Data is stored in
the control as modal values and is retained for future use in other cycles.
The machining data in a canned cycle is specified as shown below.
G __ __ X__ Y__ Z__ R__ V__ Q__ P__ F__
P . . . Specifies the dwell time at the bottom of the hole. The
relationship between the time and the specified value is the same
as for G04.
B . . . Specifies the dwell time before spindle reverse in soft left
or right tapping.
Drilling Mode Hole Position Data Drilling Data
Drilling mode . . . G__ __See canned cycle table.
Hole position data X Specifies hole position by an incremental or absolute
Y value. The path and feedrate are the same as G00
positioning.
Drilling data Z . . . Specifies the distance from point R to the bottom of the
hole with an incremental value or the position of the hole bottom
with an absolute value.
R . . . Specifies the distance from the initial level to the point R
with an incremental value or the position of point R with an
absolute value.
V . . . Specifies the first Z depth in G73 and G83.
Q . . . Specifies the increment value for G73 and G83.
F . . . Specifies the feedrate.
