New Tool for Improving the Accuracy, Documentation and Understanding of Cross Direction (CD) Mapping, TAPPICon22
The Cross Direction (CD) Mapping Common Interest Group (CIG) of the Process Control Division has
develop a tool to determine the mapping of CD actuators to the profile. This spreadsheet takes the output
of a bump test (or other method) to develop both the best linear fit and 3rd order fit mapping models. In
addition, comparison is made to the current map-in-use and a reference map (such as the previous map)
while Mapping Performance Indices (MPIs) are provided to measure the accuracy of each map. This
paper focuses on practical uses of this tool and its use with various actuator types such as slice, dilution,
water spray, steam box and induction profilers. Examples are used to show when a map needs to be
changed and how to determine if linear mapping is sufficient or if nonlinear mapping should be
implemented.
