How to improve a CAD/CAM/CNC-process: a study of organization and technology at Electrolux AE&T

Abstract [en]

This Master thesis was mainly performed at Electrolux Automated Equipment and Tooling (AE&T) in Adelaide, Australia between September 2004 and January 2005. The aim with this project was to investigate the process and co- operation of the areas CAD, CAM and CNC-machines at the plant and come up with more efficient solutions. The outcome of the project is an investment recommendation and organizational change. The project has been performed at AE&T and finished in Sweden. The current situation has been documented and analysed, literature has been reviewed, benchmarking visits have been made, a questionnaire has been sent out and the future situation and requirements have been analysed. AE&T is a toolmaking company within the Electrolux concern. Though, its "to be or not to be" has been discussed a lot during this last year. The plant was out for sale during fall 2004 as it was not a part of the core business, according to Electrolux. In December 2005, Electrolux decided to keep the business in the concern anyway. It is a tough situation for tooling companies at the moment and to be competitive on the world market one has to have an optimal and efficient organization, have skills and new technology, be suitable and helpful to meet customer requests, be time saving and have a helpful system to support the business. AE&T have the skills, but need to use them in the right place of organization and update its technology. Our recommendation is in two steps. The first is to train the CNC operators to do the CAM at the shop floor instead of having a designated CAM programmer. They also have to replace the old CNC-machines and increase the total quantity to get higher capacity and more effective production hours. The designers should become project leaders and together with a new information- and planning-system make the manufacturing go smother with lower lead times. The organization change will improve the motivation and quality in work as well as in products. Another change is to employ missing skills, like salesmen. Salesmen are needed to get more work to the shop and fill up all the three coming shifts as planned in this solution. The recommendation concerning the software is to keep the current solution, but be prepared to change software to attract more customers and come by file translation and rework and thereby also save time. The second step is to buy a new set of three CNC-machines and a new information- and planning- system that is self-learning and decision-making. The economical appraisal shows that the changes and investments for both steps are profitable and payback time is two years, which is a demand from Electrolux.
