Note
For representation in tables, it is assumed that geometry axes 1 to 3 are named X, Y, Z. The axis order (1st, 2nd and 3rd
g
eometry axis) but not the axis identifier determines the assignment between an offset and an axis.
Length compensation for tool type (SD42950 TOOL_LENGTH_TYPE)
Value of the setting data equal to 0:
The behavior corresponds to the standard definition: The lengths 1 to 3 in geometry and wear are assigned to the actual
(milling cutter / drill or turning tool).
SINUMERIK 808D/SINUMERIK 808D ADVANCED Programming and Operating Manual
Value of the setting data not equal to 0:
The assignment of the tool lengths is always independent of the actual tool type.
Value 1: Length assignment always as for milling tools.
Value 2: Length assignment always as for turning tools.
● The influence of these two setting data only refers to tool lengths. The tool radius is not affected.
● If SD42940 TOOL_LENGTH_CONST is set not equal to 0 and the value in SD42950 TOOL_LENGTH_TYPE is 1 or 2,
the related table for the assigned tool type (milling or turning tool) applies in SD42940.
SD42940 TOOL_LENGTH_CONST =18
SD42950 TOOL_LENGTH_TYPE =2
Explanation:
The active tool with the active D number always behaves as a turning tool in the length compensation (-> SD42950 =2).
The length assignment is performed in all planes G17 to G19 as for G18 (-> SD42940=18):
Length 1 -> X axis
Length 2 -> Z axis
If Y axis exists: Length 3 -> Y axis
The tool radius acts according to the actual tool type and the active plane.
