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
