8.7 Free assignment of D numbers, cutting edge numbers

Note
Unlike the process of rounding the contour (and orientation characteristics) with G642, when
rounding the orientation with OSD and/or OST, a separate block is not formed, instead the
rounding movement is added directly to the programmed original blocks.
With OSD and/or OST, block transitions cannot be rounded if there is a change in the type of
interpolation for tool orientation (vector –> round axis, round axis –> vector). These block
transitions can if necessary be rounded with the standard rounding functions G641, G642
and G643.

Free assignment of D numbers, cutting edge numbers (CE address)

Function
The D numbers can be used as contour numbers. You can also address the number of the
cutting edge via the address CE. You can use the system variable $TC_DPCE to describe
the cutting edge number.
Default: compensation no. == tool edge no.

Machine manufacturer
The maximum number of D numbers (cutting edge numbers) and maximum number of
cutting edges per tool are defined via the machine data. The following commands only make
sense when the maximum number of cutting edges (MD 18105) is greater than the number
of cutting edges per tool (MD 18106). See machine manufacturer's specifications.
Note
Besides the relative D number, you can also assign D numbers as 'flat' or 'absolute'
D numbers (-32000) without assigning a reference to a T number
(inside the function 'flat D number structure').
