This is even the case in college where the profs are great at theory but have no understanding of how it all applies in real life. That's true but I think it is getting better. I was approached by a professor who taught metalurgy of casting and joining to come to his class and present a case study. Anything that I wanted that was real world and practical. My case study was on the difficulty in maintaining the appropriate post machining flatness with cast iron saw tables. I presented the process from the foundry to the consumer and let them determine what they would do to improve the process. The students took to it with great enthusiasm. Although I provided them with a video of the process, some came to the factory to observe. The professor says he does that a lot and so do others in the Engineering Department. I can't remember anything like that happening when I was in school. Now, if we could only keep the jobs for these students in this country! Frank Try annealing or cooling in a magnetic field. See there you go. Anyone can come up with a solution if cost is not an issue. I said practical. The solutions lie in the gating methods, shake out procedure, the machining process itself. These are things that don't add cost. Requires education and experience to come up with practical solutions. No, it usually requires trial and error and a large scrap bin. If education and experience were really a factor, you wouldn't have had the problem in the first place. Education gives you the ability to anticipate problems you haven't experienced, experience gives you a quiver of solutions to problems. Problems arise due to lack of foresight, education or experience (actually poor management is the root of most problems). Most of the ways problems are solved is through trial, error and luck. Not a problem, Bob, a condition. A problem is when something changes in an established process. A condition is your start state when you want to achieve an end, maybe that has not been possible yet. And yes there could be a lot of trial and error to get there. Education and experience is what limits the amount of trial and error to get to the end. And provides criteria for prioritizing the experiments. Makes the process of improvement efficient. If I currently can hold (by statistical capability study) .008" diagonally measured flatness and I want to hold .004", I don't have a problem, I have a current state and an improvement goal. The only place education and experience really counts is for lawyers in the courtroom. For that they are richly rewarded. An engineer with 30 or 40 years experience is over the hill. Amen! |
