    How can I optimize a water meter according to SANS 1529

    Hello, thank you very much for your answer, my intention is the pdfm, the turbine type water meters, I'd like to know the work limitations and its general problems that Could happen due to wear, difficulty in speed measurement when the fluid is turbulent,...

    How can I optimize a water meter according to SANS 1529

    Hello all I need to know what are the parameters to study in a water meter to improve its functionality. I'm not asking for solutions, just the current problems that I'm supposed to know. Water meters for urban use.

    Tool steel 1.2379 or 1.2842 for bending stress on dies

    And please someone explain me please about the EDstainless comment , it is vital for me to know " If your punch has any lateral loads in it then you need to redesign you tooling. All forming tooling is a balance between toughness and wear resistance. You need a good handbook on tool steels...

    Tool steel 1.2379 or 1.2842 for bending stress on dies

    Which steels are shock resisting for high speed cold forming ?

    Tool steel 1.2379 or 1.2842 for bending stress on dies

    well I have a handbook, but the charts are not always the same, for the 1.2482 there's a chart that indicates the hardenability%/deformability% while the other doesn't have. in this tooling there has to be a side loading, unavoidably. I just wanted to know which one will perform better. could...

    Tool steel 1.2379 or 1.2842 for bending stress on dies

    Hi all Which of the above mentioned tool steels are better for cold formimg dies that will be under bending stress? The bending stress is caused by a punch that leans on a part of lower die to deform the piece. What would be the considerations in heat treatment of both?

    Which ( types of) companies usually need a solidworks macro scripter?

    Hi all I would like to know which types of companies have this kind of job and is it possible that the company would have a continous work on macro scripting

    multi-step wire drawing

    That's too philosophic. maybe it's better to compare the cases directly here, the technology is of the 20th century

    How much is it important to avoid fold in metal forming

    I would like to know in if you notice that there is a fold in a designed process, by which guidlines you might modify the design ? mechanical properties ? die wearing ?

    How much is it important to avoid fold in metal forming

    There are always possible folds like here :[link SIMULATION OF THE COLD FORGING PROCESS IN FASTENER MANUFACTURE]Link[/url] I don't know what did you mean by being established, what about other shapes? if there is more variety of shapes ? I dont have examples at hand now, but my question was...

    multi-step wire drawing

    Hi All In metal forming, theoretically, a multi-step wire drawing is better than a single step one, since the gradually drawing of the wire would lead to less defects and die wear and so on , but in practice, more dies means longer stops in case the drawing dies break or when a new wire set is...

    How much is it important to avoid fold in metal forming

    Hi All My intention of the question is cold forming of bolts, where the folding could happen during the deformation of some complex shapes. how would it affect the behavior of the product. I mean at what point the overlap of the material on itself becomes undesirable ?

    Heat transfer coefficient for tool steel ASP30

    Hi everybody I was trying to find the heat transfer coefficient (W/m2.K) for the tool steel ASP30, I haven't been able to find it so far, if you would introduce me a source to find it and also for other tool steels,I'd be very grateful

    problem with patterned tolerance of position

    @Belanger Thank you very much for your answer, if I have understood your hint, it is important to go top down, meaning from assembly to the parts, to first define the important faces ? Yes for my case all the centers are important, I did not understand the phrase : "median point of every...

    problem with patterned tolerance of position

    @DeanAllen : shall you please refer me to that ASME example as well ? The general sign of symmetry has confused me, I also needed the middle circle be symmetric with respect to the axes. this case would become harder with a circle is surrounded in a rectangular shape and its axes should be...

    How to apply the right tolerances of forms for this part ?

    Sorry , the part is supposed to have a small interaction with its mate. meaning that it should penetrate in the other piece. this is the functioning

    How to apply the right tolerances of forms for this part ?

    JNieman Thank you for your both answers, no I am not willing to make it too boring ok let's go back to your first answer, I am very sorry , but I had a hard time understanding what did you mean by the mating face, which one is it ? also how do I put a hole as a reference ? on the axis ? shall...

    Pocketing with finishing in complicated profiles

    pocketing with finishing is not possible in FAGOR C8055 if the profile is very complicated and the pocket is open from some sides. Since the mill should move along the edges of the pocket while in some parts there are no edges, meaning that the poeckt is open in some parts, so literally the...

    How to apply the right tolerances of forms for this part ?

    Thank you very much That's true that I might not be prefer to explain the application, but I think it has the solution : the teeth have or not have a important role. I would like to know the solution in both cases. I think that would be perfect Also : which book has explained the composite...
