3. Cellular Manufacturing (CM) Defined “ Cellular Manufacturing organizes the entire process for similar products into a group of team members, includes all the necessary equipment and is known as a "Cell". Merryman, Wes. Cellular Manufacturing.Online. Internet. Available at http://www.ciras.iastate.edu/CIRASnews/cellular.html Merryman, Wes. Cellular Manufacturing.Online. Internet.

4. Cellular Manufacturing Defined “…The cells are arranged to easily facilitate all operations. Parts are handed off from operation to operation eliminating setups and unnecessary costs between operations.” Merryman, Wes. Cellular Manufacturing.Online. Internet.

6. Nuts and Bolts Elimination of wastes by linking stepsElimination of wastes by linking steps –Waste is any resource not adding value to the product being manufactured In a cell, most work stations are close together so that little or no time is required to move partsIn a cell, most work stations are close together so that little or no time is required to move parts

7. Nuts and Bolts Cell teams are cross trained in cell operationsCell teams are cross trained in cell operations –Continuous improvement –Reduce lead times –Remove waste –Improve quality Product flow is more visibleProduct flow is more visible –Easier control

8. Nuts and Bolts Primary purpose:Primary purpose: –Reduce cycle time –Reduce inventories Other benefits include:Other benefits include: –Space reduction –Quality improvement –Labor cost reduction –Improved machine utilization

9. Nuts and Bolts Human resource issues:Human resource issues: –Proper training for operators –Cross functional training –Team building training for operators

10. Nuts and Bolts Human Resource issues:Human Resource issues: –Supervisors become coaches –Compensation (incentives) –Initial resistance of CM –Cells need support

13. How it Works Members of the plant team need to be involved in the changesMembers of the plant team need to be involved in the changes Other functions need to be changed:Other functions need to be changed: –Production planning and control –Purchasing –Cost accounting

14. How it works Where do you begin?Where do you begin? First, define the “cells” by the following criteria:First, define the “cells” by the following criteria: –Processes required –Part numbers and attributes –Market segments / customers –Degree of automation

15. How it Works Team selection is crucialTeam selection is crucial –Identify important skills needed such as teamwork and leadership skills –Create a process map –Develop a checklist for selecting members

16. How it Works Match skills to tasksMatch skills to tasks –Create a matrix to define who is best qualified for each task Develop team trust and motivationDevelop team trust and motivation –Manage team morale –Encourage teamwork

17. Real World Example John Deere Integrated welding work cellsIntegrated welding work cells Utilizes robotic welding processesUtilizes robotic welding processes –Faster weld times –Consistent welds –Endurance

18. Real World Example John Deere Major benefits of CM:Major benefits of CM: –Switching of welds is simple –Factory has maximum flexibility –Delivers higher quality –Faster delivery

19. Real World Example Inscape Production divided into highly specialized “cells”Production divided into highly specialized “cells” –Each cell contains equipment, technology and people –Each cell can make a wide variety of family products

20. Real World Example Inscape Major benefits of CM:Major benefits of CM: –Consistently high quality –Flexibility for customers –Quick changes in size and style –Mass customization

21. A Short Exercise How is implementing CM useful in your organization?How is implementing CM useful in your organization? How will you define cells? Form teams? Motivate and develop trust? Change functions? Change the plant layout?How will you define cells? Form teams? Motivate and develop trust? Change functions? Change the plant layout?

22. Summary CM: based on a group of different processes located in close proximity to manufacture similar productsCM: based on a group of different processes located in close proximity to manufacture similar products You must first define the “cells” and then develop a teamYou must first define the “cells” and then develop a team

23. Summary Training and support are key elementsTraining and support are key elements Many reported benefits to switching your organization to cellular manufacturingMany reported benefits to switching your organization to cellular manufacturing –Reduce inventories, and more
