Deselection Of 3D Trc - Siemens sinumerik 840D sl Function Manual

Detailed description
2.3 Selection/deselection of 3D TRC
TRC selection
The program commands used to select 3D TRC are the same as those for 2D TRC.
G41/G42 specify the compensation on the left or right in the direction of motion (the
response on selection of G41 and G42 for 3D face milling is identical). Tool radius
compensation is deactivated with G40. The approach response is always controlled with
NORM. Activation must be in a linear block.
Example:
N10 A0 B0 X0 Y0 Z0 F5000
N20 T1 D1
N30 TRAORI(1)
N40 CUT3DC
N50 G42 X10 Y10
N60 X60
N70 ...
Intermediate blocks
Intermediate blocks are permitted when 3D TRC is active. The specifications for 2D TRC
apply equally to 3D TRC.
2.3.2

Deselection of 3D TRC

Deselection
The 3D tool radius compensation function is deselected in a linear block G0/G1 with
geometry axes by means of G40.
Example:
N10 A0 B0 X0 Y0 Z0 F500
N20 T1 D1
N30 TRAORI(1)
N40 CUT3DC
N50 G42 X10 Y10
N60 X60
N70 G40 X100 Y0 Z20
N80 ...
Note
D0 is programmed via active tool radius compensation, so there is no selection. If no
geometry axis is programmed for the current plane in the block with the selection, no
selection takes place.
