Tool type (SD42950 $SC_TOOL_LENGTH_TYPE)
Definition of the assignment between tool length components (length, wear and tool base
dimension) and geometry axes independent of tool type.
Setting data not equal to zero: (the default definition is applied)
A distinction is made between turning and grinding tools (tool types 400 to 599) and other
tools (milling tools).
The value range is from 0 to 2. Any other value is interpreted as 0.
The assignment of tool length components is always independent of the actual tool type.
•
Value = 1: Always as for milling tools
•
Value = 2: Always as for turning tools
Toolholder with orientation capability
Setting data SD42900 - SD42950
Setting data SD42900 - SD42950 have no effect on the components of an active toolholder
with orientation capability. The calculation with a toolholder with orientation capability always
allows for a tool with its total resulting length (tool wear + tool base dimension). The
calculation of the resulting total length allows for all modifications caused by the setting data.
Note
When toolholders 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 toolholder 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 toolholders 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 toolholder.
