The effect of the T number call is defined in machine data. Please refer to the machine

Explanation
The free selection of the D No., "Flat D numbers", is used when tool management is done
outside the NC. In this case, the D numbers are created with the corresponding tool
compensation blocks without assignment to tools.
T can continue to be programmed in the parts program. However, this T has no reference to
the programmed D number.
Example:
Circular magazine with 12 locations and 12 single-edge tools.
