3D Touch Probe Systems
Input data
• TIME LIMIT
Time within which the touch probe must have orbited the model and
reached the first touch point to within on fourth of the programmed
probe point interval. If the entered time limit is exceeded, the TNC
interrupts the digitizing cycle.
Input range: 0 to 7200 seconds
The input value 0 means there is no time limit.
• STARTING POINT
Coordinates of the starting position in the plane perpendicular to the
probe axis.
• AXIS AND DIRECTION OF APPROACH
Coordinate axis and direction in which the probe approaches the
model.
• STARTING PROBE AXIS AND DIRECTION
Coordinate axis and direction in which the probe begins scanning the
model. Defining the direction at the same time determines whether
the subsequent machining operation is performed by up-cut or climb
milling.
• LIMIT IN NORMAL LINES DIRECTION
Distance by which the touch probe moves away from the model
surface after each deflection of the stylus during scanning.
Input range: 0 to 5 mm
Recommended input value: Enter an input value between half the
PROBE POINT INTERVAL and the PROBE POINT INTERVAL. The
smaller the ball tip radius, the larger the LIMIT IN NORMAL LINES
DIRECTION should be programmed.
• LINE SPACING AND DIRECTION
The offset by which the probe moves to start a new contour line after
completing the previous one. The algebraic sign sets the direction.
Input range: –5 to +5 mm
• MAX. PROBE POINT INTERVAL
Maximum distance between digitized positions.
Input range: 0.02 to 5 mm
