Defining the working plane via three points: PLANE
POINTS
Application
A working plane can be uniquely defined by entering
points P1 to P3 in this
PLANE POINTS function.
Before programming, note the following
The connection from Point 1 to Point 2 determines
the direction of the tilted main axis (X for tool axis Z).
The direction of the tilted tool axis is determined
by the position of Point 3 relative to the connecting
line between Point 1 and Point 2. Use the right-hand
rule (thumb = X axis, index finger = Y axis, middle
finger = Z axis (see figure at right)) to remember:
thumb (X axis) points from Point 1 to Point 2, index
finger (Y axis) points parallel to the tilted Y axis in the
direction of Point 3. Then the middle finger points in
the direction of the tilted tool axis.
The three points define the slope of the plane. The
position of the active datum is not changed by the
TNC.
