Brief description

3.1.1

General specifications

Transformation data set
A transformation is defined with a specific number of machine data. All machine data of a
transformation data set are marked using the same prefix <x>. With <x> = 1, 2, 3, ... maximum
number of possible transformations in the channel.
Example based on the transformation type of a transformation: MD24100
$MC_TRAFO_TYPE_<x>
● Transformation type of the first transformation: MD24100 $MC_TRAFO_TYPE_1
● Transformation type of the second transformation: MD24100 $MC_TRAFO_TYPE_2
● ...
Axis names
While a transformation is active, the channel, geometry and machine axis names within a
channel must be different.
● MD10000 $MN_AXCONF_MACHAX_NAME_TAB (machine axis name)
● MD20080 $MC_AXCONF_CHANAX_NAME_TAB (channel axis name)
● MD20060 $MC_AXCONF_GEOAX_NAME_TAB (geometry axis name)
3.1.2

5-axis Transformation

Function
The "5-Axis Transformation" machining package is designed for machining sculptured
surfaces that have two rotary axes in addition to the three linear axes X, Y, and Z. This package
thus allows an axially symmetrical tool (milling cutter, laser beam) to be oriented in any desired
relation to the workpiece in the machining space.
The path and path velocity are programmed in the same way as for 3-axis tools. The tool
orientation is programmed additionally in the traversing blocks.
The real-time transformation performs the calculation of the resulting motion of all 5 axes. The
generated machining programs are therefore not machine specific. Kinematic-specific post-
processors are not used for the 5-axis machining operation.
