Figure 7.9 Finding an internal corner position
Description
This cycle is used to establish the corner position of a feature.
NOTE: A true corner intersection can be found, even if the corner is not 90 degrees.
Application
The probe must be positioned with its tool offset active at a start position as shown in the
figure above. The probe measures the Y axis surface first and then measures the X axis
surface. The probe then returns to the start position.
Errors occurring during the cycle return the probe to the start position.
NOTE: If the I and J inputs are missing, only two gauging moves occur. The corner
feature is assumed to be parallel to the axes.
If either I or J are missing then three gauging moves occur and the corner feature is
assumed to be 90 degrees.

Figure 9.1 4th axis X measurement
Description
The purpose of this macro is to find the slope of a surface between two points Z1 and Z2
and make the necessary correction by indexing a ‘rotary axis’ to compensate. It also
updates a ‘work zero point’ for that axis if required.
Application
The 4th axis must be positioned to the expected angular position of the feature (i.e.
surface normal to the Z axis). The cycle finds the error of surface position, and then
adjusts the axis work offset or checks a tolerance.
NOTE: It is normally necessary on most machines to re-state the work offset and move to
the angular position after the cycle to make the new work offset active.
