Improving Cross Direction Mapping Webinar

Virtual Webinar
Wednesday, September 07, 2022 to Wednesday, September 07, 2022

Modify the set-up of the mapping tool and apply it to a new actuator set and machine.

September 7, 2022 | 1PM - 2PM (ET)

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.

Who Should Attend: 

Job Titles

  • Process Control Engineers
  • Process Engineers
  • Asset Lead and Mill Manager


  • Pulp and Paper 
  • QCS Suppliers 
  • QCS Maintenance

Learning outcomes: 

  1. Modify the set-up of the mapping tool and apply it to a new actuator set and machine.
  2. Analyze the results of the tool and use the Mapping Performance Indices (MPIs) to determine the accuracy of the various potential maps.
