Figure 9.3 4th axis Y 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.

Figure 9.5 Bore / boss on PCD measurement
Description
The macro measures a series of bores or bosses on a pitch circle diameter (PCD). All
probe moves occur automatically and return to the start position at the centre of the PCD.
Application
1.
The probe is positioned at the centre of the PCD above the component. The probe
moves to all bore/boss features and measures each feature automatically. The
probe then returns to the PCD centre at the end of the cycle.
2.
The macro makes use of the bore/boss macro which is nested within the moves.
This means that the macro nesting level is four deep, which means that this macro
cannot be nested inside a customer macro.
3.
If a “probe open” condition occurs during any of the moves between bore/boss
features a path obstructed alarm occurs and the probe stays in position instead of
returning to the start position as is usual. This is done for safety reasons because
the return path to centre line of the PCD may be obstructed.

Figure 9.6 Measuring the stock allowance
Description
The cycle measures either an X or Y or Z surface at defined positions to establish the
maximum and minimum stock condition of the surface.
Application
The probe should be positioned above the surface at the first measuring position. The
cycle measures the surface at this position (P1). Additional points P2 to P6 maximum are
measured as defined, depending on the number of sets of I, J, or K inputs.
NOTES:
1.
If setting a work offset, the surface position will be at the minimum measured position
and the stock value is seen in #196.
2.
If NOT setting a work offset the nominal position is assumed and the maximum and
minimum values are seen in #194 and #195.

Description
This macro is used to turn the probe on prior to it being used. The probe is loaded into the

In the event of a start-up failure, there is a loop in the software which tries to activate the
probe up to four times. An alarm results if the probe does not activate.
It should be noted that a small automatic Z axis movement takes place within the macro to
test if the probe is active.
NOTE: The probe tool offset must be active.

It should be noted that a small automatic Z axis movement takes place within the macro to

Application
Data for P1 and P2 must already be stored in variables #180 to #184, and #185 to #197
for P2, by running suitable measuring cycles.
NOTE: The order P1 and P2 is important, because the data calculated is that of P2 with
respect to P1.
Values for P1 are obtained by programming G65 P9834 without any inputs after the first
measuring cycle.
Values for P2 are obtained by running a second measuring cycle - the feature-to-feature
data is established by programming G65 P9834 with suitable inputs after the second
measuring cycle.

Figure 9.15 Determining feature-to-feature data in the Z plane
Description
This is a no-movement macro that is used after two measuring cycles to determine
feature-to-feature data.
Application
Data for P1 and P2 must already be stored in variables #180 to #184, and #185 to #197
for P2, by running suitable measuring cycles.
NOTE: The order P1 and P2 is important, because the data calculated is that of P2 with
respect to P1.
Values for P1 are obtained by programming G65 P9834 without any inputs after the first
measuring cycle.
Values for P2 are obtained by running a second measuring cycle, and the feature-to-
feature data is established by programming G65 P9834 with suitable inputs after the
second measuring cycle.
