Tool Compensation
D function
The tool edge is programmed with D1 (edge 1) to D9 (edge 9). The tool edge
always refers to the currently active tool. An active tool edge (D1 to D9) without
active tool (T0) is not active. Tool edge D0 deselects all tool compensations of
the active tool.
Selecting the edge
on tool change
After programming a new tool (new T number) and changing this tool, the
following possibilities to select the edge are provided:
Activating the tool
compensation
Tool radius
1.
The edge number is programmed.
2.
The edge number is not programmed. D1 is active automatically by
default.
D1 to D9 are used to activate the tool compensation of a tool edge for the active
tool. However, tool length compensation and tool radius compensation become
active at different moments:
z
The tool length compensation (TLC) is realized with the first traversing
movement of the axis in which the TLC is to be active. This traversing
movement must be a linear interpolation (G0, G1).
z
The tool radius compensation (TRC) becomes active by programming
G41/G42 in the active plane (G17, G18 or G19). The selection of TRC by
G41/G42 may only be performed in a program block with G0 (rapid
traverse) or G1 (linear interpolation).
