Where with such a mill you are able to set the helical interpolation such that you end up with a multi start point thread. I do remember the turning insert being from a specialty catalog but even so, if you are working with softer metals such as brass it would be possible to make such a tool out of HSS. Thanks for the link — interesting. It seems the graphic on the linked page shows an example of a two-start insert tool.

It seems the first and second cut tool vees are of different height, perhaps this for the first cut to be of lesser depth where the second cut is deeper to finish. But at the end of the insert tool travel, the first cut will never be completely deep enough.

I guess this is OK if the finished mating part has some other means to stop further travel, but is not ideal IMO. I think each cut multi-start thread should end with the same thread depth. Perhaps a better implementation would be an insert cutting tool that has two vees offset by degrees with the first following the second, and by extension a three-start having three vees offset by degrees each following in insert travel one after the other.

I was only using it as an example as multi point tooling is starting to get into specialty tooling. The example i provided is meant to reduce the number of passes by doing multiple cuts with one tool for a singe start thread but if you check out this milling tool:. I have seen turning tools with even length teeth but they were in a specialty tool catalog for softer materials. Thread milling has generally taken over in CNC operations, both in hmcs and vmcs.

A CNC lathe with live tooling and the right cam software can churn out internal multi start threads with very little trouble. Had my first try and making an internal thread on a part with a custom tool on the CNC machine. Now I am wondering why I even bothered had tapping any threads : although the forming tools are not cheap the finish is perfect every time. Doing threads on a non-CNC lathe is easy.

There should be a setting for threading and a little counter so you can start the threads perfectly timed every time. Most common use of multi-start screws is probably jar lids. It significantly reduces the difficulty in locating the lid correctly to start screwing it on.

Double thread screws are made to go in quicker in assembly time. I have had Italian made organs use these in the pedal board holding the spring tension in the metal springs. In order to save a few seconds we have self disassembly that continually falls apart. Leonard: What would you be if you were attached to another object by an inclined plane, wrapped helically around an axis?

Sheldon: Screwed. Leonard: There you go. Film at That being said, there are other methods to bring strength back into the part through heat treating or anodizing. Instead i would be buying them based off of bolt grade, the interior threads into billet components would also be designed in such a way that the forces acting upon the bolt are not in an axial direction but in a radial direction.

Maybe someone here will be able to help me. I am looking for a formula or on-line calculator or some hint how to calculate the following: I want to attach electric motor to a pair of rods with thread and I want it to lift lower around kg in around 1 m range. Distance between rods will be aroound Stability will be provided by other means. Any tips? From your travel speed and gravity, you can calculate the potential energy gained in the lift and hence the motor power. One of the glass cases contained examples of wooden artifacts taken from the tomb.

To my amazement there were some hand made wood screws looking exactly like modern day wood screws. Firstly threads have a mesh ratio. Metric — A M2. Some metric screws are available with both a course and fine thread. Threaded rod is often Whitworth. This standard has some peculiarities. The other trap is the numbering system changes. The second number is the Threads per inch TPI. A lot of camera gear both video and still use UNEF threads for the lenses regardless of their origin…. Yes they are but they are not an American standard.

Depends on what you call a gun — I think of them as machines. Many barrel threads are Whitworth — including those for the fantastically common German Mauser. While the discussion has been about screw design and standards mostly, I feel compelled to mention how I solved a problem with screws.

The case screws on a Honda XR I used to own kept coming loose, even with just one ride. I added some silicone RTV to the threads, and they never came out without a screwdriver after that. The chain had damaged the case in front of it, and would let dirt in to contaminate the points. I happen to work in the automotive industry and deal with this kind of issue regularly, using loctite or similar is actually a poor solution as it may just be hiding the problem which could come back to bite you when you least expect it.

If that tension should drop to zero, the friction between the components also drops to zero, allowing them to move around which could eventually lead to fracture of the bolts or components. More often than not the culprit is either compressible material in the joint e. Interestingly, the solutions are often counter intuitive, e. The majority of bolted joints rely on the clamp force which is generated by the torquing or tensioning of bolts to sustain the forces which are applied.

The inclusion of a gasket in a joint to prevent leakage is only effective as long as there is sufficient clamp force generated by the bolts to allow effective sealing. With forces applied to the joint, the forces are transmitted by friction as a result of the clamp force generated by the bolts, leading to a secure bolted connection.

Thread stripping can be a problem in many designs where tapped holes are required in low tensile material. In general terms, thread stripping of both the internal and external threads must be avoided if a reliable design is to be achieved. If the bolt breaks on tightening, it is obvious that a replacement is required. When a bolt is being tightened, two threads are mated together, which leads to the tightness of the bolt. When the two threads are mated together, a shear stress is applied across the threaded section.

If this stress becomes too high, the section will shear. This is known as thread stripping. Thread stripping internally strips parts of the internal thread itself and becomes embedded around the external thread. This type of bolt thread stripping is very serious, and must never be allowed to occur. Its occurrence is a certain sign that there is something seriously wrong with the bolts.

If it is observed, the bolting procedures must be re-examined and re-evaluated immediately. If it is allowed to persist, serious consequences may result because the bolts will not only sustain a preload, but external loadings may be transmitted directly to the bolts and cause joint failure. Fatigue failures typically occur within a couple of threads, where the bolt engages into the internal thread.

Failure is then reached due to the high stress gradient within the region. Fatigue failures can be particularly hazardous because they often occur with no visible warning signs and the failure is often sudden. Fatigue failures are often unknowingly avoided in gasketed joints simply because the required crush for the gasket often dictates a torque or bolt tension that minimizes the risk of a fatigue failure.

However, changing to a new gasket type later on which requires less crush may be the initial cause of bolt fatigue failure. It is not unusual to assume that a bolt has failed due to overload when it has in fact failed from fatigue, which can also be a consequence of self-loosening. Bolt overload is a result of the applied force being sufficiently high causing the bolt to fail due to overload.

This is a direct result of the axial force being applied acting upon the bolted joint, which then causes the bolt fractures in the threaded area. Bolts are typically made from high strength steels, which when fully tightened, exert high clamp force onto the joint. The area directly under the bolt head or nut face sustains the high bearing stress.

If a maximum stress limit for the joint material is exceeded, then deformation occurs over a period of time. This leads to the extension being lost in the bolt, resulting in the clamp force subsequently being reduced. Bolts are considered to transfer force between the connected members, one of the ways bolts transfer force is called bearing.

The bearing method assumes that the bolt contacts the side of a hole and there is a compressive force between the bolt and the side of the hole. The magnitude of this compressive force is limited by the strength of the material to handle this compressive force. Steel after all, is a Chrystal structure. It has many hackable features for the engineering staff to explore. And in all this so far, no mention of materials science behind the stock used to manufacture the product.

The tensile strength of the material is as important as the type of pitch, mesh, etc of the screw itself.
