8. HOW TO USE THE INSTRUMENT
8.1 MACHINE ORIGIN SELECTION
Before using the instrument to measure any tool, you have to set a correct
starting reference: the origin.
When switched on the instrument suggests the origin M0 as a default with the
same refences and the same options radius/diameter, millimetre/inch,
absolute/incremental enabled when the machine was switched off.
It is not possible to associate toolsets to the M0 origin, so it will be possible
to measure tools and print labels but not the storage of measured dimensions.
To create a valid zero reference for M0 you require a sample tool which has
known X and Z dimensions.
Insert the sample tool into the spindle, rotate the tool in the spindle, and rotate
it to find the maximum tangency, then collimate the profile with the central
reticule (see para.7.3.1). Now it’s possible to setup the measurement of the
sample tool by touching the screen where the measurements are displayed.
A numerical icon board will appear; type the radius of the sample tool (e.g.
), then press
Touch the screen again in the measurement display zone.
Digit now the default tool length
(e.g.
), then press
.
Eventual typing errors can be corrected by pressing the cancellation icon
.
The new absolute axes origin set is automatically stored and will be active
again at the next switch on of the instrument, right after the reference point on
both axes is taken (para. 6.4.1 switch on).
For how to store the machine origins see chapter 9.
þ
The setting of the values is possible only for the “absolute” measurement
that will be enabled at the end of the operations.
þ
The setup operations of the measurements is usable also in “auto-
collimation” mode; in this case it will be sufficient to frame the tool and
rotate the spindle to find the position of maximum tangency, the
measurement inserted will be relative to the individual point automatically
measured.
