Before a cycle definition you must have programmed a
tool call to define the touch probe axis.
The TNC always measures the first line (parallel to the
reference axis) 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 below).
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
