P1: Transverse axes

4.1

Function

Transverse axis
Within the framework of "turning" technology, the transverse axis refers to the machine axis that
travels perpendicular to the axis of symmetry of the spindle, in other words, to longitudinal axis
Z.

Geometry axis as transverse axis
Every geometry axis of a channel can be defined as a transverse axis.
For the geometry axis as a transverse axis, the following functions can be simultaneously or
separately permitted and activated:
● Programming and display in the diameter
● Reference axis for constant cutting speed G96/G961/G962
Several transverse axes in the channel
The introduction several transverse axes in the channel involves a functional decoupling of
diameter programming and reference axis for G96/G961/G962. Diameter programming and
reference axis for G96/G961/G962 can be active for different transverse axes (see table below).
