14.8 Compensating workpiece misalignment with a 3-D touch probe
Probing with inclined touch probe
Another way to set a basic rotation is to manually position the axes to
any desired inclined angle. This may be necessary if the positions of
the touch points make it impossible to probe them with the home
setting of the rotary axes.
Overview
If inclined probing is necessary, do not activate the
function for tilting the working plane. Otherwise the TNC
will not show the selection soft keys for the basic rotation
function.
Cycle Soft key
Basic rotation using 2 points:
The TNC measures the angle between the line
connecting the two holes and a nominal position
(angle reference axis).
Basic rotation using 2 holes/studs:
The TNC measures the angle between the line
connecting the centers of two holes/studs and a
nominal position (angle reference axis).
Workpiece alignment using 2 points:
The TNC measures the angle between the line
connecting the two points and a nominal position
(angle reference axis) and compensates the
misalignment by turning the rotary table.
