Manual Operation and Setup
14.5 Datum management with the preset table
Soft key Function
Directly enter the new datum without calculation
of the kinematics (axis-specific). Only use this
function if your machine has a rotary table, and
you want to set the datum to the center of the
rotary table by entering 0. This function only
saves the preset in the axis in which the cursor is
currently hovering. Enter the desired value in the
pop-up window. If inch display is active: Enter the
value in inches, and the TNC will internally convert
the entered values to mm
Select BASE TRANSFORM./OFFSET view. The
standard BASE TRANSFORM. view shows the X,
Y and Z columns. Depending on the machine,
the SPA, SPB and SPC columns are displayed
additionally. Here, the TNC saves the basic
rotation (for the Z tool axis, the TNC uses the
SPC column). The OFFSET view shows the offset
values for the preset.
Write the currently active datum to a selectable
line in the table: This function saves the datum
in all axes, and then activates the appropriate
row in the table automatically. If inch display is
active: Enter the value in inches, and the TNC will
internally convert the entered values to mm
