Special handling of tool compensations

18.10.1

Relevant setting data

SD42900- 42960
Setting data SD42900 - SD42940 can be used to make the following settings with reference to tool
compensation:
• Sign of the tool length
• Sign of the wear
• Behavior of the wear components when mirroring geometry axes
• Behavior of the wear components when changing the machining plane via setting data
• Allocation of the tool length components independent of actual tool type
• Transformation of wear components into a suitable coordinate system for controlling the effective tool length
Note
In the following description, the wear includes the total values of the following
components:
•
•
You will find detailed information about sum and tool offsets in:

Required setting data
• SD42900 $SC_MIRROR_TOOL_LENGTH (mirroring of tool length components and components of the tool
base dimension)
• SD42910 $SC_MIRROR_TOOL_WEAR (mirroring of wear values of tool length components)
• SD42920 $SC_WEAR_SIGN_CUTPOS (sign evaluation of the wear components)
• SD42930 $SC_WEAR_SIGN (inverts the sign of the wear dimensions)
• SD42940 $SC_TOOL_LENGTH_CONST (allocation of the tool length components to the geometry axes)
• SD42950 $SC_TOOL_LENGTH_TYPE (allocation of the tool length components independent of tool type)
• SD42935 $SC_WEAR_TRANSFORM (transformation of wear values)
• SD42960 $SC_TOOL_TEMP_COMP (tool length offsets)
