7.2.2 Tool Length Offset Measurement inside the Machine

Tool length can be measured also inside the machine. For this softkey F4 T. LENG MEAS- UR (tool length measurement) of F5 OFFSETS action menu must be selected.

Select the tool length offset register, in which the tool length to be stored. In order to do this softkey F3 OFS NO SEARCH (offset number search) must be pressed. The offset register num- ber, which is to be used in the course of measurement, shall be entered under address N in the bottom data input line, than the

data input must be terminated by either key or

.

The coordinate system, to which the tools are to be related to, needs to 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 execution of the appropriate command G54, G55, ...), but is only taken into account in the course of measurement.

After taking cuts on X and Z axes, measuring the diameter X and length Z of workpiece cut, the values are to be specified in the lower data input line on address X and Z. The data input

must be terminated by either key or

.

The control calculates the tool length offset automatically by taking the current axis position into account.
