Integrating CNC technology and the JIT Kanban System: A case study
by Amrik S. Sohal, Glenn Lewis, Danny Samson
International Journal of Technology Management (IJTM), Vol. 8, No. 3/4/5, 1993

Abstract: This paper describes the implementation and integration of Computer Numerically Controlled (CNC) flexible machining lines and computerised Just-in-Time Kanban system in an Australian company engaged in the manufacture of timber window and door frames. The planning, sourcing, implementation and integration issues are discussed in some detail. A significant factor in the success of the implementation was the attention paid to the human element of the project and the acceptance of change by all staff as a positive and constructive process. Critical to the solution developed was the use of customised software which was written on a commonly used relational database. A careful balance between the technology aspects, commercial and human aspects was absolutely necessary. One of the major reasons for the high return on investment achieved was the simultaneous implementation of the management system with the CNC technology. The benefits obtained from the new production system include the reduction in change over and set-up times from 5-6 hours to about 90 seconds; stockouts or shortages of components totally eliminated; total stockholdings reduced by over 50%; and the quality of finished products improved significantly.
