Rotation of milling and drilling tools

2.9.3.1

Cutting edge position for milling and tapping tools

Milling and drilling tools
Milling and drilling 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
Cutting edge position
A cutting edge position which is modified accordingly has also been introduced for the milling
and tapping tools defined as specified above (see Chapter "Modifications during rotation of
milling and tapping tools (Page 150)").
Note
A cutting edge position that is declared for tools that are not milling or tapping tools, or turning
tools according to the definitions stated above, 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:
