Special characteristics of orientable tool carriers

Setting data SD42900 - SD42950
Setting data SD42900 - SD42950 have no effect on the components of an active tool carrier
with orientation capability. The calculation with a tool carrier with orientation capability always
allows for a tool with its total resulting length (tool length + wear + tool base dimension). The
calculation of the resulting total length allows for all modifications caused by the setting data.
Note
When tool carriers with orientation capability are used, it is common to define all tools for a non-
mirrored basic system, even those, which are only used for mirrored machining. When
machining with mirrored axes, the tool carrier is then rotated such that the actual position of the
tool is described correctly. All tool-length components then automatically act in the correct
direction, dispensing with the need for control of individual component evaluation via setting
data, depending on the mirroring status of individual axes.
The use of tool carriers with orientation capability is also practical if the physical characteristics
of the machine type prevents tools, which are permanently installed with different orientations,
from being rotated. Tool dimensioning can then be performed uniformly in a basic orientation,
where the dimensions relevant for machining are calculated according to the rotations of a
virtual tool carrier.
