NC setting data

- Approach & retraction behavior with 2-1/2D tool radius compens.
-
- -
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

|__________
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 example 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 compensation 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 contain 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 grinding tools with
tool point direction 0 or 9 or other undefined values are treated like milling tools.
