Description:
This setting data controls the approach and retraction behavior with tool
radius compensation if the activation or deactivation block does not contain
any traversing information. It is only evaluated with 2-1/2D TRC
(CUT2D or CUT2DF).
The decimal coding is as follows:
N N N N
| | | |____ Approach behavior for tools with tool point direction
| | | (turning tools)
| | |______ Approach behavior for tools without tool point direction
| | (milling tools)
| |________ Retract behavior for tools with tool point direction
| (turning tools)
|__________ Retract behavior for tools without tool point direction
(milling tools)
If the position in question contains a 1, approach or retraction is always
performed, even if G41/G42 or G40 stands alone in a block.
For example:
N100 x10 y0
N110 G41
N120 x20
If a tool radius of 10mm is assumed in the above example, position x10y10 is
approached in block N110.
If the position in question contains the value 2, the approach or retraction
movement is only performed if at least one geometry axis is programmed in the
activation/deactivation block. To obtain the same results as the above exam-
ple with this setting, the program must be altered as follows:
N100 x10 y0
N110 G41 x10
N120 x20
If axis information x10 is missing in block N110, activation of TRC is
delayed by one block, i.e. the activation block would now be N120.
If the position in question contains a 3, retraction is not performed in a
deactivation block (G40) if only the geometry axis perpendicular to the com-
pensation plane is programmed. In this case, the motion perpendicular to the
compensation plane is performed first. This is followed by the retraction
motion in the compensation plane. In this case, the block after G40 must con-
tain motion information in the compensation plane. The approach motions for
values 2 and 3 are identical.
If the position in question contains a value other than 1, 2 or 3, i.e. in
particular the value 0, an approach or retraction movement is not performed
in a block that does not contain any traversing information.
About the term "Tools with tool point direction":
These are tools with tool numbers between 400 and 599 (turning and grinding
tools), whose tool point direction has a value between 1 and 8. Turning and
