3. BASIC OPERATIONS
Step 5 Enter 30mm, the distance to the next machining point.
The KA counter corrects the previous positioning error, -0.005mm and displays
the actual distance the machine needs to move to reach the next machining
point.
Feed the machine table to the machining position.
Step 6 To quit the zero-approach machining function, press the Zero-approach key or
the Cancel key.
NOTE
• It is recommended not to perform zero-approach machining on the X-axis. (For more
information, refer to the “Zero-approach machining on the X-axis” shown below.)
• It is possible to zero-set the counter during zero-approach mode. However, if the
counter is zero-set, the accumulated error up to that point cannot be corrected.
• If the zero-approach mode is entered from the ABS coordinate, zero-setting of the
X-axis cannot be performed.
• If the zero-approach machining function is deselected, the display contents will restore
those before selecting the function. Zero-setting, machining point setting, etc., which
were performed in the zero-approach mode will not affect the counter operation.
TIP
• Zero-approach operation on the X-axis
To machine according to the figure shown on the left, the value
to be entered in the counter must be twice the value a and b (2a
and 2b).
Generally, the diameter is used in the drawings for lathe
machining (see the figure on the left). Therefore, it is
recommended to machine using the displayed ABS coordinate
value instead of using the zero-approach function, since the
displayed ABS coordinate value is equal to the dimension to be
machined.
