6 As soon as the sensor detects contact with the circumference, input a
skip signal to the machine, thus stopping the axial movement of
manual handle feed or jog feed. Simultaneously, the position at
which feed stopped is stored as the first measurement point. The
machine coordinates of the stored measurement point are displayed at
the bottom right of the screen, as follows:

OFFSET SETTING WORK (OPRT)
7 Move the measurement probe to the second measurement point. At
this time, the CNC interlocks the machine to prevent the probe from
moving in the direction in which it was moved so as to touch the
current measurement point. For example, when the probe touched the
measurement point after being moved in the +X direction, movement
of the probe to the next measurement point is allowed only in the –X
direction. Movement in the +X, +Y, or –Y direction is interlocked
until the skip signal is set to 0. Once the probe touches the second
measurement point, follow the same procedure as that for storing the
first measurement point.
8 Once the probe has touched the third measurement point, press soft
key [MEASURE B], then
[CENTER]. This calculates the center of
the hole from the coordinates of the three measured points, then sets
the X– and Y–axis workpiece origin offsets. To cancel and restart
measurement at any point, press the
RESET
key. Pressing the
RESET
key
clears the coordinates of all stored measurement points.
Definitions 1 and 2, described in ”Definition of tool length offset” in
Explanations for measuring the tool length offset, also apply to the
general concept of the Z–axis workpiece origin offset, as follows:
(1)Definition 1
In definition 1, the Z–axis workpiece origin offset is defined as the
distance from the machine zero point to the origin of the workpiece
coordinate system.
