Function Soft key
Directly transfer the actual position of the tool
(the measuring dial) as the new datum: This
function only saves the datum in the axis which
is currently highlighted.
Assign any value to the actual position of the tool
(the measuring dial): This function only saves the
datum in the axis which is currently highlighted.
Enter the desired value in the pop-up window.
Incrementally shift a datum already stored in the
table: This function only saves the datum in the
axis which is currently highlighted. Enter the
desired corrective value with the correct sign 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.
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 datum in the axis which is currently
highlighted. 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 the BASIC TRANSFORMATION/AXIS
OFFSET view. The BASIC TRANSFORMATION
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 to 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.
