Procedure for Setting Tool Length Offset
Note: there is an alternative method for setting tool lengths on 31.
A tool length offset is used to compensate for the
difference between Z axis home and part surface (part
zero). Setting floating zero in Z axis is not
recommended.
To set tool length offset, load tool #1 in the spindle by
doing an MDI→ T1M6. Use handwheel or jog to t
the tool on the part at a known location. Select F6
(ZTool). The control will prompt you to enter the Z
position to be set. A tool length offset for tool #1 has
been set. Now when tool #1 (H1) is programmed to a
position, it will position in reference to part zero.
Repeat this procedure for each tool.

A tool length offset can also be set by entering a value
into a tool offset table. The value can be measured by
touching the part with the tool and reading the current
position of the Z axis. If a shim is used between the
tool and the part, the shim dimension should be added
to the offset value. To enter the value select F7 (
-F3 (Tool). Then enter the value as a negative number.
