Digitizing

Digitizing Cycle LINE (18)

Cycle 18 LINE is for digitizing a 3D surface in lines in one direction.

It was developed mainly for digitizing with rotary axes.

Define Cycle 5 RANGE or 15 RANGE

TOUCH PROBE: Select Cycle 18 LINE

Line direction: Coordinate axis of the digitizing lines.

Scanning angle: Direction of touch probe traverse relative to

the axis entered in line direction

Height for feed rate reduction: Coordinate in the tool axis at which

at the start of each line the TNC switches from rapid traverse to

the probing feed rate.

Feed rate F: Maximum digitizing feed rate

Min. feed rate: Feed rate for scanning the first line

Feed rate reduction at edges: Distance at which the TNC begins to

reduce the scanning feed rate before steep edges

Min. line spacing: Minimum distance moved forward to start the

next line at steep surfaces

Lline spacing an direction: Maximum distance moved to start the

next line

Max. probe point interval

Tolerance value: The TNC suppresses the storage of probe

points whose distance from a straight line defined by the last two

stored points is less than the tolerance value.

The line spacing and max. probe point interval cannot exceed

20 mm!
