Explanation Of The Terms: Swivel, Frames And Traori - Siemens SINUMERIK 828D Manual

Important functions for 3- to 5-axis machining
3.2 Explanation of the terms: swivel, frames and
TRAORI
The swivel (CYCLE800) and TRAORI features can be used to control rotary axes and angle the
tool in relation to the machining surface. During swiveling, the rotary axes are positioned once
and the linear axes X, Y, Z move during machining. The tool is oriented from a start position
through to an end position and will then only work with the three linear axes. It is aligned in
relation to the surface by means of a static process.
In contrast to swiveling, TRAORI is a dynamic process. The rotary and linear axes can be
traversed simultaneously during machining. The orientation of the tool in space can be changed
continuously. All axes (rotary and linear axes) are interpolated at the same time.
Frames affect only the coordinate system and only the coordinate system is modified,
for example, rotated, scaled or moved. CYCLE800 takes the machine kinematics into account
during swiveling, i.e. attention is paid to tool compensations and zero points. In the case of
frames (e.g. ROT), these must be taken into account by the user.

The frame is a self-contained arithmetic rule
that transforms one Cartesian coordinate
system into another Cartesian coordinate
system.
In the example, the coordinate system is twice
subjected to translatory movement. This is the
case, for example, if you set the zero point at
the corner of the workpiece by means of zero
offset.
The tool is aligned with the machining surface
by moving the rotary axes. This example
involves rotation of rotary axis B
tool is positioned in relation to the XY plane
. Machining then takes place in this plane.
