Touch Probe Cycles: Automatic Workpiece Inspection | POLAR PRESET (Cycle 1)

16.3 POLAR PRESET (Cycle 1)

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!
The TNC moves the touch probe in a 3–D movement at rapid
traverse to the pre-positioning point programmed in the cycle.
There is a danger of collision according to the previous position
of the tool.
Pre-position 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
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.
