Abstract
This master thesis is on Statistical Process Control (SPC). The objective is to evaluate if SPC can be used in a process that produces plates for heat exchanger, the process evaluated is located at Alfa Laval Lund AB. The products are produced in the process by punching and shearing metal coils. An ambition in the project is also to increase the knowledge about Statistical Process Control at Alfa Laval therefore one part of the project is to hold an in-house education.
A big part of the thesis consists of theory around Statistical Process Control. This is both for the education and for the understanding of the subject.
Machine capability and process capability tests have been made to evaluate the process. After analysing the test results... (More)

A big part of the thesis consists of theory around Statistical Process Control. This is both for the education and for the understanding of the subject.
Machine capability and process capability tests have been made to evaluate the process. After analysing the test results the values were satisfying. The process can be brought to statistical control and it should not be a problem to implement Statistical Process Control, at least not for capability reasons. The process is greatly complex and there are a lot of different products produced so it will be a lot of work to start up Statistical Process Control. (Less)
