CNC Z32 - Programming Guide (LATHES)
Circular interpolation (G2 – G3)
Allows to program a circular arc.
The direction of the linear interpolation is set with G2 or G3.
In case the working plane
G25ZX
has been specified, the following rule apply:
G2
-
clockwise
machining
G3
-
counterclockwise
machining
On machines with downward positive X axis, the directions are inverted, as shown in the figure below:

Nella figura sono mostrati I
sensi di percorrenza dei cerchi.
Sono presi in considerazione
archi di cerchio effettuati con X
positive e archi di cerchio
effettuati con X negative (linea
tratteggiata) per il caso di
torrette posteriori.
A G2/G3 movement is specified with the following syntax:
G2 I… J… Z… X… F…
or
G3 I… J… Z… X… F…
I
indicates the Z coordinate of the arc center, expressed as absolute (non incremental) value
J indicates the X coordinate of the arc center, expressed as absolute (non incremental) value
Z
is the final position along Z reached at the end of the interpolation
X
is the final position along X reached at the end of the interpolation
F
is the feed used for the interpolation. If not programmed, the last programmed value remain valid.
Warning: If the contouring plane is different from ZX plane, but is for instance the VW plane, the syntax
becomes:
G3 I.. J.. V.. W..
where “I” indicates the first axis of the contouring plane (V) and “J” the second axis (W)
