8.7 Free assignment of D numbers, cutting edge number CE
(as of SW 5)
As of SW5, you can use the D numbers as contour
numbers. You can also address the number of the
cutting edge via the address CE.
You can use the system parameter $TC_DPCE to
describe the cutting edge number.
Preset: offset number == cutting edge number
References: FB, W1 (tool offset)
Machine manufacturer (MH 8.12)
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). Please refer to the data of the machine
tool manufacturer.
Additional notes
Besides the relative D number, you can also assign
D-numbers al 'flat' or 'absolute' D-numbers
(1–32000) without assigning a reference to a
T-number (inside the function flat D number
structure).
