Hi all Hopefully everyone is doing good. I have a question regarding the Throw Out. With this I mean the material in industry that is, by whichever kind of accident, unnecessarily lost. There are many subjects that can done that such as: - poor drawings - worker interrupted doing his job - bad material - bad machine tools - too low education of the worker - wrong dimensions - too rare quality assurance (inbetween of process, during the process, and perhaps at the start) - too late delivery - wrong delivery - no tutors - wrong understanding of process - and many many more What we get, in the industry if this is happening too often? The answer is very simple. Too much material spent, a way too high costs, unnecessary replacements of jobs and so on. We all know to what "drives" this huge issue of, many, productions. In the company where I started working as a student, I got a suggestion to start working on Lowering the throw out. Since I still have to choose my diploma project topic, I think this could be my topic. I have, in purpose, to work on this approximately 5 months or half year. Probably this won't be enough so, if needed, I will extend the deadline of the diploma (it is possible). There is no way that this could be done in just a few weeks. Where I want to lower the Throw Out? Mostly in our production of screws. When they are made, also the process of rolling (to create the threads on the screws) is required, sometimes also milling for the top of screws. After all this, the screws are send to thermal and surface processing. So the production of screws is the main part where I would like to do my diploma, to lower all the throw out. Besides this, I would also try lowering it on the stamping processes such as reaming and deep reaming, cold forming rolling conveyors and so on. But my main focus would be the production of screws. I also have access to the machine called Dimac MCV. It does a hell of a job. It automatically check huge amount of screws through two cameras - one for dimensions and one for the top of the thread. The screws are comming to the rotary disc, connects to them and after being scanned (usually after doing the 290 degree circle) they are thrown in two different boxes - one for good parts (according to dimensions and fine ones) and one for bad parts. Its huge machine and does a lot of controlling the screws. I can check my knowledge, whatever I will do, on this machine if it doesn't run already. I would like to know if anyone could please suggest me any books for lowering the throw out, to save the material and costs of production company? Where should I start and how? I would like to begin from zero and choose this as my diploma project. On this I would work approximately 5 or 6 months. Thank you for the replies. Kindest regards.
