sustain the changes. The first part of this work was started with a focus of making the work place friendlier and more organized to work. All the operators in the cell were formally introduced to 5S and were made aware of the work which is going to be done.

The next important focus was on setup time reduction. There was no standard way of doing the setup and each and every operator uses their own convenient way to do the setup. This inconsistent process also depends very much on the skill of the operator. As there is a mix of new less experienced operators and very high skilled experienced operators there is a need for standardization in setup to save time and to share knowledge and experience. In the newly formed cell there is a mix of both manual, old machines and highly automated machines. In order to have consistent flow, Total Productive Maintenance (TPM) concepts were introduced to the operators/machinists who could make the machines more reliable. There were cases where a series of repairs happened in a particular machine which eventually led the machine to stop for weeks for maintenance thus affecting the cell throughput.

The next important part of this work is focused on cycle time reduction. This was one of the main departmental objectives in this particular cell. A particular operation named operation C took a lot of time ranging from 60 hours to 90 hours to complete the turning operation. This time depends on the diameter of the part and the material type.

As these parts are custom made depends on the material and size there is a lot of practical difficulty in machining the parts due to their design. For each setup the jaws of the particular size has to be made and it takes a considerable amount of time to complete it which adds to the increase in non value added time in the process. So the main focus in this part is to reduce the variation when compared to the standard routings time and to reduce the non value added time.

The main tools used to solve the problems were to involve all the team members of the area and ensure individual empowerment and accountability, with a relentless focus on new process sustainability.

1.4 Objectives

The objective of this thesis is to establish methods for developing standardized work for high-variety, low-volume (HVLV) job shop environments. Ideally these methods should exhibit the following characteristics:

As jobs are continuously changing, there is a need to develop a good documentation of standardized work. These documents should be useful in the study of work methods, identifying flaws in the process and seeking remedy for the situation.

The standardized method should educate floor workers and seek acceptance of the standard work process, cultivate interest by encouraging a participative approach to standardization. This is accomplished through a learning environment where every individual on the shop floor is allowed to think and contribute to continuous improvement.

Learning that occurs gradually and intermittently over a long period of time, should not be forgotten and should be recalled and used consis本论文由英语论文网提供整理，提供论文代写，英语论文代写，代写论文，代写英语论文，代写留学生论文，代写英文论文，留学生论文代写相关核心关键词搜索。
