Before a cycle definition you must have programmed a
tool call to define the touch probe axis.
The TNC always measures the first line in the direction of
the minor axis of the working plane.
By defining the positions of the measuring points 1 and 3
you also determine the corner at which the TNC sets the
datum (see figure at right and table at lower right).
Corner X coordinate Y coordinate
A Point 1 greater than
point 3
Point 1 less than point 3
B Point 1 less than point 3 Point 1 less than point 3
C Point 1 less than point 3 Point 1 greater than point 3
D Point 1 greater than
point 3
Point 1 greater than point 3
