9.1 NC MACHINE ORIGINS
In case of tool measurement options, there are no particular problems in the X-axis radial measurements,
but a conventional reference point must be established for length (Z-axis) measurements. In fact, when a
tool radius or diameter is measured, the zero point will always be located on the tool, the situation is quite
different for length measurements. For this reason, the tool presetter must be reset on this same point for
the Z-axis of this NC machine (absolute machine zero-point, spindle nose, etc.).
The simplest method is to measure a master gauge or a reference tool directly on the NC machine, the
dimension is then transferred to the tool presetter. The radius and length measurements set on the machine
will then be shown on the display.
A more efficient system is to use the same origin given by the length marked on the reset gauge, for all of
the machines having the same spindle intersection.
The electronic equipment of the E236+ gives freedom of choice in which system to use in order to express
the length on axis Z and includes in preset functioning the self-learning of the origins for each machine or
group of machines according to the system applied.
It is possible to specify for each machine either as radius or as diameter, the unit of measure. All the settings
stored for each machine become active simultaneously with the origin shifting, that is every time they are
recalled, and thus avoiding any possible error.
