coordinate values. The system uses the first and second Cut Verify models

to find their Y coordinates and Theta angle (see

Figure 6-21).

Setting the Yes/No parameter called "Shrinkage before cutting" to Yes

allows the shrinkage algorithm to be fully activated prior to the cutting

stage.

6.1.8 Average Index

When the index in a part of the cut map changes, the system can be set up

to calculate the average index. The system finds the first and the last

model of each cut verification sequence and calculates the average index

for each group of indexes.

When the nominal distance between the first and last index of an

application is known, a Nominal Distance algorithm can be employed.

Nominal Distance defines the assumed, or estimated, distance between the

highest and lowest points along the Y-Axis, between which the streets are

located. It enables measuring a vertical distance between two cut-verify

models and calculating an average index. This feature is based on the

existing average index State Machine.
