NOTE
Pressing the key resets the displayed T and M
addresses to 0. Once MEM or MDI mode has been
selected, however, the modal T and M codes are displayed.

4 Use the numeric keys to enter the distance from the base measurement
surface to the measurement surface, then press soft key
[HM INPUT]
to set the distance. For details of the measurement surface and base
measurement surface, see Explanations, below.
5 Select the tool for which the tool length offset value is to be measured.
While ”OFST” is blinking at the bottom of the tool length offset
measurement screen, a T code or M code can be specified in manual
handle feed or jog feed mode (manual numeric command). First,
enter Ttttt (where tttt is a T code number), then press the cycle start
button on the machine operator’s panel or MDI panel. The Ttttt
command is executed, thus selecting the tool to be measured. Then,
usually, enter the M06 command to move the tool to the spindle
position. Once the tool for which the tool length offset is to be
measured has been selected at the spindle position, position the cursor
to the tool offset number with which the tool length offset for the
selected tool is to be stored. The positioning of the cursor to the offset
number is usually done by the operator. Some machines, however,
automatically position the cursor to an appropriate tool offset number
upon the completion of tool selection, if bit 5 (QNI) of parameter No.
5005 is set to 1.
6 Perform manual handle feed or jog feed to move the tool until it
touches the measurement surface of the workpiece or reference block.
7 Press soft key
[MEASURE B]. The tool length offset is stored in the
tool offset memory. If tool offset memory B or C is being used, the
tool length offset is set as the tool geometry value, while 0 is set as the
tool wear offset. The cursor remains positioned to the set tool offset
number. To automatically advance the cursor to the next tool offset
number upon the completion of the setting an offset, press soft key
[MEASURE B+], instead of [MEASURE B].
8 Once the tool length offset has been set, the tool is automatically
moved to the tool change position.
9 This completes tool length offset measurement for a single tool. To
measure the tool length offsets of other tools, repeat steps 5 to 8.
10 Once the tool length offsets of all tools have been measured, set the
tool offset measurement mode switch on the machine operator’s
panel to OFF. The ”OFST” blinking indication is cleared from the
bottom of the screen.
