3.9 Orientation
0xxx The path-relative orientation is also maintained in activation or deactivation blocks of the tool
1xxx The path-relative orientation is not maintained in activation or deactivation blocks of the tool
Address names for the lift vector components
The address names for the lift vector components are defined using machine data:
MD10624 $MN_ORIPATH_LIFT_VECTOR_TAB[ <vector component> ] = <name>
Example with standard data
Note
Naming convention
The rules defined by MD20080 $MC_AXCONF_CHANAX_NAME_TAB should be complied
with for axis identifiers.
Address names for the safety factor for orientation change
Normally the retracting movement is performed simultaneously to the orientation change. The
address name for safety factor R can be defined using machine data:
MD10626 $MN_ORIPATH_LIFT_FACTOR_NAME = "<name>"
If safety factor R is greater than 0.0, then the orientation is only changed if the tool is traversed
by safety clearance S in the direction of the lift vector. Safety clearance S is calculated as
follows:
S = R * lift vector amount; definition range of factor R: 0 ≤ R < 1

offset.
offset.
Note
The tool orientation normally remains constant in the activation or deactivation blocks of the tool
offset. However, in these blocks it is permitted to program a tool orientation, which is then
traversed through in these blocks. However, programming the orientation in these blocks is only
possible with vectors; it is not permitted to program rotary axis positions.
Machine data
$MN_ORIPATH_LIFT_VECTOR_TAB[ 0 ] = "A8" ; x coordinate
$MN_ORIPATH_LIFT_VECTOR_TAB[ 1 ] = "B8" ; y coordinate
