- Thread lead
In feed-per-minute mode, the thread lead is obtained from the
expression, feedrate y spindle speed. In feed-per-revolution mode, the
thread lead equals the feedrate speed.
- Tool length compensation
If a tool length compensation (G43, G44, or G49) is specified in the
canned cycle, the offset is applied at the time of positioning to point R.
- Axis switching
Before the drilling axis can be changed, the canned cycle must be
canceled. If the drilling axis is changed in rigid mode, P/S alarm (No.
206) is issued.
- Hole machining
Hole machining is not performed by a block that does not contain X, Y,
Z, R, and additional axes.
Specify R in a block that performs drilling. If R is specified in a non-
drilling block, it is not stored as modal data.
Do not specify a G code of the 01 group (G00 to G03 or etc.) is set to
1)) and G84.2 in a single block. Otherwise, G84.2 will be canceled.
- Tool offset
In the canned cycle mode, tool offsets are ignored.
- Amount of movement and feedrate
The table below indicates an amount of travel along the Z-axis and the
amount of spindle movement based on linear interpolation, and
Table 13.2.1 (a) Amounts of Movement and Feedrates
Amount of movement Feedrate/speed
Z-axis z = Distance from point R to point Z
Fz = F command value
Spindle s = z×(S command value/F command
Fs = S command value (min
