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.

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?

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

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...

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 ?

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

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...

Hi All Shall I ask you to explain me a bit more about the context of this link ? here I need to apply a tolerance of form on a piece with similar shape, that the small holes that are patterned aroun the center should be symmetric repect to the vertical axis of symmetric of the big circle, (...

Hi All I would like to know the most correct way to apply the tolerances of form in this part, since it is gonna be cut in a wire cut machine. Since the part is not round, I have some doubts. I appreciate your attention

Hi all I use SolidWorks in the company I work. And now I am working on lay out design of some machines to be transfered to another part. Since I have noted that some softwares have a module called layout design, I was curious to know what are the particular things to be considered, apart from...

Hi All I don't know whether I don't know the terms or the language is difficult, here is the paragraph : Typical of this class, in which comparison of the visual appearance of a smoke plume is compared directly with a standard scale of grey, is the Ringelmann Chart4. In this, a white card, on...

I appreciate any book and article suggestions

Hi All I am looking for force sensors used for crank presses that work with a rate of 150-250 rpm and a force of 100-150 tons .So far I just found force sensors for maximum 50 tons , and I am not sure if these sensor can stand this working rate and if it's possible to dismantle and reuse them...

The steel wire reels that are used to feed cold forging machines for bolt production, if are of small diameter , like 5 or 6 mm , produce a knod or block due to bad wire arrangement. Is there a new solution or idea that this would completely be avoided automatically ?

Hi All do decrease part of a cylindrical steel, we use backward extrusion (not hollow ) , but I notice that in the region of diameter change and also further ahead ( I mean where we have only the lower extruded diameter , that to me seems that there should be less contact and friction ), the...

For a mechining site that makes tools for production and maintenance, imagine that there is a high variety in the parts complexity and also the priority changes, I mean every now and then, we might have a new problem with a broken machine or tools. While there are some pieces are regular to be...

Hi All We have to replace a roller bearing with the code : STO8ZZ Torrington V.50 Czech From <http://webshop.abfbearings.com/Bearing/STO8ZZTORSUPPORTROLLER/655834> http://webshop.abfbearings.com/Bearing/STO8ZZTORSUPPORTROLLER/655834 On it, but the strange thing is that the catalogues ...

Hi All I am trying to use the tolerance standards more appropriately and with more sense, but regarding to the work we do , that is for the different machines that we have , we happen very often to be obliged to replace a broken piece. for example I see that sometimes tolerances like -+0.01...

To shrink fit carbide in steel , there is a formula given in some catalogues , that is kind of blind and not possible to get , cause the P : pressure between the cylinder is unknown , and it's not said how much it should be please check this link for the formula, page 6 Link

Hi EveryBody I am facing some problems due to some doubts, in a metal forming process simulation (upsetting ) , I used Rigid Dies, and after the simulation and formation of the matal , I wanted to find the stress on the dies in some point, so since the dies were rigid and nothing was...
