7.2.1 Work Zero Point Offset Measurement
If work offset is to be measured
inside the machine, select
F3 W.
OFFS MEASURE (work offset
measurement) screen of OFF-
SETS screen menu and press
the action menu key.
The coordinate system to be
measured can be selected after
pressing softkey
F1 WORK
COORDNT. (Work coordinate
system), than the appropriate
softkey
F1 G54, F2 G55, ... The
selected coordinate system is not
changed to (as after the execu-
tion of the appropriate com-
mand G54, G55, ...), but is only
taken into account in the course of measuring.
Basically there may be two kinds of tool length offsets. One possibility is that the tool length
offset equals to the X- and Z-direction tool overhang. Another one is that the tool length is
actually a coordinate offset in the direction of tool length. The control enables the operator to
take the size of a tool which is known, into account when measuring the offsets.
The length offset storage to which the coordinate system is to be measured, can be selected.
In order to do this the action key
F3
OFS NO SEARCH (offset number search) must be
pressed. The offset register number, which is to be used in the course of measuring, shall be
entered under address N in the bottom data input line, than the data input must be terminated
by either key or .
