15.3 POLAR DATUM PLANE (Cycle 1,
software option 17)

Cycle run

Touch Probe Cycle 1 measures any position on the workpiece in
any direction.
1 The touch probe moves at rapid traverse (value from FMAX
column) to the starting position
2 Then the touch probe runs the probing process at the
probing feed rate (column F). During probing the TNC moves
simultaneously in two axes (depending on the probing angle).
The probing direction is defined by the polar angle entered in
the cycle.
3 After the TNC has saved the position, the probe returns to the
starting point. The TNC also stores the coordinates of the touch
probe position at the time of the triggering signal in parameters
Q115 to Q119.

Please note while programming:

Danger of collision!
Pre-position the touch probe in order to avoid a
collision when the programmed pre-positioning point
is approached.
The probing axis defined in the cycle specifies the
probing plane:
Probing axis X: X/Y plane
Probing axis Y: Y/Z plane
Probing axis Z: Z/X plane

Cycle parameters

Probing axis: Enter the probing axis with the axis
selection keys or ASCII keyboard. Confirm your
entry with the ENT key. Input range: X, Y or Z
Probing angle: Angle, measured from the probing
axis, at which the touch probe is to move. Input
range -180.0000 to 180.0000
Nominal position value: Use the axis selection
keys or the ASCII keyboard to enter all coordinates
of the nominal pre-positioning point values for
the touch probe. Input range -99999.9999 to
99999.9999
To conclude the input, press the ENT key.
