Welcome to The Engineering Toolbox Channel, where I give you the tools you need to solve real-engineering problems! I cover topics like Engineering Software, CAD, engineering tutorials, Excel, manufacturing, Six sigma, and Lean manufacturing.
My mission is to provide you with the tools you need to be successful in your engineering career. We all know school can only teach you so much and our industry is ever changing.
If you have a topic you'd like to me to cover, please let me know! I am not an expert in everything but I do have a wide range of skills. Even if I don't know the answer to your question, I will be glad to go find the answer, and distill everything down into a practical video that everyone can benefit from!
Seems like doing all the calculations before starting production would lead to an unacceptable amount of setup time where I work. I'm new to press break and received minimal training so I'm stuck trying to figure this shit out on my own.
Should be able to do the calculations ahead of time and create a lookup table/matrix for easy reference on the floor. Check out this video. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-C6bdWhlF5I0.htmlsi=sIB40Kmb2s4k4oUa Also, most companies these days are using automated press brakes where tooling is selected and predefined in the program. In those cases these calculation are done “off-line” when decided what tooling the program should use. Or even built into the programming software so tooling is automatically selected without needing someone to manually decide. This way the program tells the machine and operator what tooling is used for consistent part geometry.
@TheEngineeringToolboxChannel I'm using an old Toyokoki, the software it runs is from 1996. It's doesn't have all those fancy features. I'm constantly having to apply tape to the back gauges and shim the dies to compensate for tapering along flange length and angle. Pain in my ass. I'm definitely going to keep this channel handy, though. Thanks.
Excuse my limited knowledge about space, but I have a thought experiment. Yes, this project is expensive and may not be able to clean small parts, but it can send a strong message to companies and government sectors to act more responsibly in space. Just like we do on Earth, we should be mindful of our actions there. Despite the notion that space is vast, I believe that space debris could eventually form a synthetic moon. Returning to the topic, this is a great project, and I am proud of those motivated to pursue it. However, I have a suggestion for anyone capable of building it. Again, excuse my limited knowledge about astronomy, but why can't we use high-power lasers from the ground? I know it would require a lot of science and money, but if we could destabilize objects in space by heating them beyond their current state of energy and mass, and if lasers can have this effect, I believe the project would receive substantial funding and support. In fact, this could shift humanity's ideology towards this challenging task. As a computer engineer, my suggestion is to create a prototype and test it. This could work.
For 3d cad, meshing and post processing you have salome-platform, specially 3d cad module shaper. It is great. I highly recommend it and it is really not well known. Free and opensource
Conceptually this is correct but if you start applying this to building design there are a lot of the particulars that aren't quite in accordance with building codes such as AISC.
incredible tutorial very easy to follow even for a beginner like me saved my skin today I had to have this exact thing done for my applied maths homework and didn't't know where to start thanks :)
In this example I believe I just used a generic value for steel. In practice you would get this from the real properties of the material you are using (which would be acquired from the material supplier or through your own testing)
You lost me at the 5 minute mark using a table that was not introduced in the video beforehand. I had no context. I would be nice to know what to do without use of the table lookups
I want to say fuck you to all the Programmers of the world. You could have created only one software but decided to create one thousand trillions. You deserve the hell you created for yourself.
Octave is a good alternative to matlab as well. I currently use freecad with the cfdof workbench for all my cfd. I also use prepomax to mesh stl files, step files and the use prepomax to do my fea and its free
Hi, that's the difference between a signal within a process that is "in control" and an indication that the process is not in control? It looks as though an out of control process is one that has lots of signals. Is the response to signals if both "out of control" and "in control" not the same between these two states i.e. that you should react to signals and not to noise? How is 'out of control' specifically defined? Thanks
This is a good question…In control vs out of control is really a moment in time characterization. So short answer is if you have a signal, the process is out of control and ideally you should take action to investigate why. A process is in control when no signals are detected in the most recent sample. A process is OC when the most recent sample shows an out of control signal. So over a long run, it’s very possible that a process has been both in control and out of control at different time periods. Knowledge of the process, the amount of risk associated with OC datapoints, and resources available to react to them will dictate how you respond to OC data points. If a process is frequently OC, it just means it’s generally a process that goes out of control and needs more attention.
@@TheEngineeringToolboxChannel Thanks so much for your fab answer. This makes a lot of sense and makes this method feel much clearer now :) Great video (and enviable Excel skills). I've subscribed.
Your video is missing a very important piece of information: How do you calculate the bend deduction? You use the flat length to calculate the bend deduction and then use the bend deduction to calculate the bend allowance, but you need either one of these two to calculate the flat length, so pretty much you can't determine any three of this variables.
I think you are confused. Where do you think BD, BA, k-factor come from? They come from empirical results (measuring real trial pieces). You are correct… flat length is calculated from BD, BA, or k-factor. But how do you get those values in the first place? You have to start with a sample of known length, then bend it and see what happens! From that you can interpret any of the bending factors you desire, store them in a library and use them in the other direction to estimate flat length given (bend radius, material type, thickness, etc etc).
Then I think including how you determined the bend allowance or the bend deduction from the empirical data or the type Of empirical data would greatly benefit the quality and comprehensiveness of your video. Of course I’m confused. I came to this video to understand sheet metal because I want to learn not because I already know about the topic
@ritchieron1 fair enough. The equations are really all you need. Just like any algebra problem you always start with what you know and calculate what you don’t know. In the case of sheet metal bending, you know what you physically have in front of you. The flat piece, the piece after it was formed, the tooling you used, etc. From the physical part (empirically) you know flat length, flange 1, flange 2, radius, material thickness. Plug these into formulas and that will allow you to calculate BD, BA, or k-factor as needed.
@@TheEngineeringToolboxChannel Thanks for your answer. Unfortunately in my case where I work, what I need to determine is the flat length. I receive materials to be used and rough geometries as inputs and from that I need to work the flat length to fabricate the final part. For this I need to either know the K factor or the bend allowance. The bend allowance can easily be calculated by knowing the neutral axis shift. Since I need the K factor to determine the Neutral axis shift I can't calculate the bend allowance or vice - versa. Hence my line of questioning.Thanks for the discussion and the exchange of ideas! Cheers
