I - 4 Turning Specific Operations
Press the LOCK AXIS soft key while the tool is still cutting.
Retract from the current position.
Turn the spindle off, and measure the workpiece diameter.
Enter the measured diameter, or radius, and press ENTER.
Remember to ensure the 200S is in diameter display mode Ø if you
input a diameter value.
Datum Setting
See "Datum Soft Key" on page 20 for basic information. Datum
settings define the relationships between the axis positions and the
display values. For most lathe operations there is only one X-axis
datum, the center of the chuck, but it may be helpful to define
additional datums for the Z-axis. The table can hold up to 10 datum
points. The recommended way to set datum points is to touch a
workpiece at a known diameter, or location, then enter that dimension
as the value that the display should be showing.
Example: Setting a workpiece datum
Preparation:
Call the tool data by selecting the tool which you are using to touch
the workpiece.
Press the DATUM soft key. The cursor will be in the DATUM
NUMBER field.
Enter the datum number, and press the DOWN arrow key to go to
the X-axis field.
Touch the workpiece at point 1.
Enter the radius or diameter of the workpiece at that point.
Remember to ensure the 200S is in diameter display mode Ø if you
input a diameter value.
