Brief description
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.
Definition
Every geometry axis of a channel can be defined as a transverse axis.
However, only exactly one transverse axis can be defined per channel.
A transverse axis is a linear axis for the following functions, which can be permitted and
activated at the same time or separately:
• Programming and display in the diameter
• Reference axis for constant cutting speed G96/G961/G962
Overview of the transverse axes functions
Diameter programming and reference axis for G96/G961/G962 can be active for different
transverse axes (several transverse axes in a channel).
