3.3 Automatic Workpiece Measurement

DATUM PLANE (touch probe cycle 1)

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 1 programmed in the cycle.

2 Then the touch probe runs the probing process at the probing feed

rate (column F). During probing the TNC moves simultaneously in

2 axes (depending on the probing angle). The scanning 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.

8 Probing axis: Enter the probing axis with the axis

selection keys or ASCII keyboard. Confirm your entry

with the ENT key.

8 Probing angle: Angle, measured from the probing

axis, at which the touch probe is to move.

8 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.

8 To conclude the input, press the ENT key.

Before programming, note the following

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
