6 MOTION PROGRAMS FOR POSITIONING CONTROL
6.13.21 G44 Tool length offset (-)
Code G44
Function Tool length offset (-)
The axis travels with the preset offset value subtracted from the travel
command.
By setting a difference between the tool length value and actual tool
length as the offset value, a program can be created without being
aware of the tool length.
Format
4
Offset data number
4 X x h ; G H
Positioning address
Axis name
[Explanation]
(1) By executing this command, the axis travels to the position which results from
subtracting the offset value set in the tool length offset data setting registers from
the end position of the travel command.
(2) In the following cases, the tool length offset command is cancel.
G49 ; Tool length offset cancel command
G43 H0 ;
G44 H0 ;
(3) This command can be set to one axis only. If two or more axes are commanded
simultaneously, it is valid for the last specified axis.
G44 X1. Y1. Z1. H1 ; Z-axis is valid.
If no axis is specified, the last specified axis is made valid.
G01 Z1 ;
G44 H1 ; Z-axis is valid.
(4) As this command is a modal instruction, the offset value is retained until the offset
value is cancel (G49).
(5) Tool length offset may be made to only one axis simultaneously. (Both G43 and
G44)
