9.4 G81. Turning canned cycle for straight sections
This cycle turns the programmed section maintaining the indicated pass between the successive
turning passes. The cycle allows to select whether or not it will run a finishing pass after completing
the programmed turning operation.
The basic structure of the block is as follows:
G81 X Z Q R C D L M F H
X±5.5
It sets the X coordinate of the profile's starting point. It must be programmed in absolute coordinates
and in the active units, radius or diameter.
Z±5.5
It sets the Z coordinate of the profile's starting point. It must be programmed in absolute coordinates.
Q±5.5
Defines the X coordinate of the final point of the profile. It must be programmed in absolute
coordinates and in the active units, radius or diameter.
R±5.5
Defines the Z coordinate of the final point of the profile.
C5.5
Defines the turning pass. It is given by a positive radius value. If programmed with a 0 value, the
CNC will display the corresponding error message.
The whole turning operation is carried out with the same pass which is the same or smaller than
the programmed one "C".
D 5.5
It sets the safety distance the tool withdraws after each pass.
When programming D with a value other than 0, the cutter withdraws at 45º until reaching the safety
distance (left figure).
