7.14 PROGRAMMING WITH REAL Y AXIS
Machines that have the axis Y option can make transverse movements of the turret of 64 mm (from –32
to +32).
Through this option it is therefore possible to make radial machining that is not perpendicular to the
centre of the workpiece (out of axis), for example drilling and tapping out of axis in relation to the centre of
the workpiece.
Planes milling can be carried out using a radial module (which is physically impossible using the G112
imaginary co-ordinates) providing it is compatible with the i +/- 32 mm stroke of the turret.
For programming axis Y is treated like another real axis (X,Z,C etc) and will have a positive direction
(toward the operator) or a negative direction (toward the machine interior)
The lathe with axis Y is always a machine with a motor driven turret and axis C, therefore the functions
already described are valid.
In machines having this option, before rotating the turret it is necessary to reposition axis Y to zero by
programming the instruction G0 Y0
If it is required to make a circular interpolation (G2/G3) of axes Y and Z, the work plane where the arc is
found (G19) must be specified and after the operation has terminated, return to the normal work plane
(G18).
