Feedrate overrides are ignored during left-handed tapping. A feed hold doesn't stop the
machine until the return operation is completed.
Before specifying G74, use a miscellaneous function(M code) to rotate the spindle
counterclockwise.
When the G74 command and an M code are specified in the same block, the M code is
executed at the time of the first position operation. The system then proceeds to the next drilling
operation.
When a tool length offset (G43, G44, or G49) is specified in the canned cycle, the offset is
applied at the time of positioning to point R.
Note: 1. Before the drilling axis can be changed, the canned cycle must be canceled.
2. In a block that does not contain R, K , drilling is not performed.
3. Specify P in blocs that perform drilling. If they are specified in a block that doesn't perform drilling,
they cannot be stored as modal data.
4. Do not specify a G code of the 01 group(G00-G03) and G73 in a single block.Otherwise, G73 will be
canceled.
5. In the canned cycle mode, tool offsets are ignored.
6. During rigid tapping, Spindle-feedrate override and Feed-feedrate override don’t work.
Parameters Sets for Rigid Tapping :
1, Standard tapping, following Spindle_Encoder mode, P411=2 in Axis parameter, CNC
system must be configured with SP-encoder
Special Note: When the transmission ratio between Spindle and Encoder is not 1:1, it must be configured
with SZGH Transfer Board & modify P412 & P413 in Axis parameter;
412, Number of spindle teeth
413, Number of encoder teeth
2, Rigid tapping, interpolation between Spindle & Drilling axis, P405=5, P410=94, P411=3 in
Axis parameter..
M75: Shift control mode of spindle to Position Control Mode(Pulse+Direction). After rigid
tapping, M74, cancel position control mode of spindle.
Rigid mode eliminates the need to use a floating tap required in the standard tapping mode,
thus allowing faster and more precise tapping.
Example
