Cutting edge position for milling and tapping tools
Milling and tapping tools
Milling and tapping tools means the following tools whose tool type ($TC_DP1) has values in the range of 100 to
299.
Tools are treated independently of tool type such as milling and tapping tools if:
SD42950 $SC_TOOL_LENGTH_TYPE = 1
Length of cutting edge
A cutting edge position is also introduced for the so defined milling and tapping tools which is modified according
to the following description, in case of rotations.
Any specified cutting edge position for tools that are not milling and tapping tools or turning tools according to the
mentioned definitions, is not evaluated.
The cutting edge position of the tapping and milling tools is stored in tool parameter $TC_DP2 as in the case of
turning tools. Based on the definition of the cutting edge position for turning tools, this parameter can assume the
values 5 to 8. Here, the cutting edge position specifies the orientation (the direction of the rotation axis) of the
tool:
