ADTECH9 Series CNC Programming Manual
Specify the repeat times of fixed cycle in current positioning point;
if K isn’t specified, NC considers that K=1; if K is specified as 0,
the fixed cycle won’t be executed at current point.
➢ The hole processing specified by Gxx is modular, and the fixed cycle can be canceled with G80 or 01 G
instruction.
➢ Hole processing parameter is also modular, and will be retained before changed or fixed cycle is canceled,
even hole processing mode is changed.
➢ A hole processing parameter can be specified or changed when specifying a fixed cycle or at any moment
in the fixed cycle.
➢ Repeat times K isn’t a modular value, and is only specified when required.
➢ Feeding speed F is a modular mode, and it will be retained even the fixed cycle is canceled.
➢ If NC system is reset while executing the fixed cycle, hole processing mode, hole processing parameter
and repeat times K are canceled.
The following example describes above content better.
Specify the rotation, and specify the spindle to rotate positively
Locate specified X, Y point quickly, process with the hole processing
parameter specified by Z, R, F and in the hole processing mode
specified by G81, and repeat for K times; when the fixed cycle is
started, Z, R, F are necessary hole processing parameters.
X axis doesn’t move, Y axis quickly positions the instruction point
and processes the hole; the hole processing parameter and hole
processing mode retain the modular value in 2. The K value in 2 is
invalid.
Hole processing mode is changed; hole processing parameter Z, R, F
retain the modular value, specify the value of hole processing
parameter P and specify the repeat times K.
The fixed cycle is canceled, and all hole processing parameters
except F are canceled.
Since the fixed cycle has been canceled when executing 5, all
