W1: Tool offset
2.15 Sum and setup offsets
Type of action of the individual vectors
The type of action of the individual vectors or groups of vectors depends on the following further
quantities:
Influencing quantity
G commands
Tool type
Machine data
Setting data
Tool carriers with orientation capability
Adapter transformations
Distribution over the geometry-axis components
How the three vector components of partial totals of the vectors involved are distributed over
the three geometry-axis components is determined by the following quantities:
Influencing quantity
Active processing level:
G17 X/Y direction
G18 Z/X direction
G19 Y/Z direction
Tool type:
Milling tools, drilling tools, grinding tools, turning tools
SD42900 $SC_MIRROR_TOOL_LENGTH
SD42910 $SC_MIRROR_TOOL_WEAR
SD42920 $SC_WEAR_SIGN_CUTPOS
SD42930 $SC_WEAR_SIGN
SD42940 $SC_TOOL_LENGTH_CONST
SD42950 $SC_TOOL_LENGTH_TYPE
Adapter transformations
The resulting tool orientation always remains parallel to one of the three axis directions X, Y or
Z and exclusively depends on the active machining plane G17-G19, since it has not yet been
possible to assign the tool an orientation.
Stepless variation of the tool orientation
The toolholder with orientation capability also enables the tool orientation to be varied
steplessly, in addition to providing further offsets or linear expansion fluctuations with the aid of
offset vectors l
For further explanations, see Section "Tool carriers with orientation capability (Page 95)".
