10.6.3 Tool offset number D
Functionality
It is possible to assign 1 to 9 data fields with different tool offset blocks (for multiple cutting
edges) to a specific tool. If a special cutting tool is required, it can be programmed with D
and the corresponding number.
If no D word is written, D1 is automatically effective.
If D0 is programmed, the offsets for the tool are ineffective.
The tool radius offset numbers are automatically generated when a tool is created (all 9
cutting edges). The cutting edges of the tool have a fixed meaning (geometric position on the
grinding wheel). Cutting edges 1, 3 and 5 describe the left wheel edge, cutting edges 2, 4
and 6 describe the right wheel edge for standard contours.
The same applies for all contours (including free contours) when compensating the dressing
amount, which means that the odd numbers are left (negative wear value) and the even
numbers are right (positive wear value). The wear in direction X (diameter) is the same for all
points (negative for grinding direction in negative direction). Cutting edges 7 to 9 are the
three possible dressers of a wheel. They are permanently assigned to the sections of the
wheel.
Dresser 1 (D7) Left wheel edge
Dresser 2 (D8) Right wheel edge
Dresser 3 (D9) Optional for the diameter and if dresser 1 or 2 is not used.
Option: If the dresser is a diamond roller dresser, which only performs immersion dressing,
dresser 1 is always significant here. The other dressers are not used.
Programming
D...
; Tool offset number: 1 ... 9, D0: No compensations active!
Information
The tool offsets of the T/D fields have permanent meanings that are entered in the tool
management. A list of the parameters appears later in this Section.
Tool length compensations become effective immediately when the tool is active; when no D
number was programmed with the values of D1.
The compensation is retracted with the first programmed traversing of the associated length
compensation axis.
A tool radius compensation must also be activated by G41/G42.
