# How to contribute to threadlib
|
||||
|
||||
Thank for considering a contribution to threadlib! Any help is greatly
|
||||
appreciated.
|
||||
|
||||
|
||||
## Did you find an issue?
|
||||
|
||||
* Check whether your issue has already been reported by searching under
|
||||
[existing issues](https://github.com/adrianschlatter/threadlib/issues).
|
||||
|
||||
* If don't find an issue addressing the problem, open a new issue.
|
||||
|
||||
* Choose a meaningful title, describe clearly what you consider to be a
|
||||
problem.
|
||||
|
||||
* If possible, provide example code or other means to make it easy for a
|
||||
maintainer to reproduce your problem.
|
||||
|
||||
|
||||
## Did you write a patch?
|
||||
|
||||
You already have a solution for an issue or a new feature? All the better! A
|
||||
pull request ("PR") is what you want to do.
|
||||
|
||||
* Open a new [pull-request](https://github.com/adrianschlatter/threadlib/pulls)
|
||||
with your patch.
|
||||
|
||||
* Try to create PRs that address a specific issue/feature/topic.
|
||||
|
||||
* Avoid PRs containing an assortment of unrelated fixes and features. Better
|
||||
split it into separate PRs for each topic.
|
||||
|
||||
* Clean up your code before creating a pull request: Remove code that you have
|
||||
commented out for debugging, remove test code you have added, e.g., inside
|
||||
threadlib.scad.
|
||||
|
||||
* Make sure the PR's description clearly describes the problem and your solution.
|
||||
Include relevant issue numbers if appropriate.
|
||||
|
||||
* You increase the chances of quick acceptance of your PR significantly if you
|
||||
have taken measures to assure quality (such as writing and passing tests).
|
||||
|
||||
|
||||
## You intend to contribute new threads?
|
||||
|
||||
That's what we need the most! This is how to do it:
|
||||
|
||||
* Find the specs (usually specified in a norm, sometimes published openly)
|
||||
|
||||
* Convert these specs for use in threadlib:
|
||||
|
||||
* Find help on this topic in [Design of threadlib](docs/DesignOfThreadlib.md)
|
||||
and [Creating Thread Specs](docs/CreatingThreadSpecs.md)
|
||||
|
||||
* Use existing threads as examples. You find them beneath design/
|
||||
|
||||
* When done, proceed with a pull request (see "Did you write a patch?" above)
|
||||
|
||||
|
||||
## Final remarks
|
||||
|
||||
Currently, threadlib is maintained in the spare time of a single person having
|
||||
a family and a job. If you do not get immediate feedback to your issue or pull
|
||||
request, please have some patience.

Note that for a nut you also have to specify an outer diameter. The inner
|
||||
diameter is implicitly given by the thread designator ("M12x0.5" in this case).
|
||||
|
||||
To make a threaded hole (e.g. in a plate), an intuitive approach would be to
|
||||
create the difference of the plate and a bolt. However, this part would not work
|
||||
well in practice: You need a little space around the bolt to avoid collisions.
|
||||
threadlib's solution is to provide the tap module:
|
||||
|
||||
.. code-block:: OpenSCAD
|
||||
|
||||
tap("G1/2", turns=5);
|
||||
|
||||
.. image:: docs/imgs/tap-G1o2.png
|
||||
:alt: G1/2 tap
|
||||
|
||||
The tap shown above *is* intended for use like this and has accounted for the
|
||||
allowances needed in practice. Also, it will create the tapers:
|
||||
|
||||
.. code-block:: OpenSCAD
|
||||
|
||||
difference() {
|
||||
part_to_be_tapped_here();
|
||||
tap("G1/2", turns=5);
|
||||
}
|
||||
|
||||
Make sure that the tap extends a tiny bit out of the part to be tapped.
|
||||
Otherwise, you will end up with infinitely thin artifacts covering the entrance
|
||||
of your tapped hole.

|

## Thread Basics
|
||||
|
||||
As an example, we use British Standard Pipe parallel (BSPP) thread (see drawing below). The black curve shows the parting line between internal and external thread. In an ideal world, both threads are created according to the parting line. For BSP thread it is based on a fundamental triangle with a 55-degree angle rounded to a radius r.

Reality is a bit more complicated: If one of the threads deviates only a little in the wrong direction, the threads collide. Therefore, the pitch radius r_pitch (radius where distance between falling and rising edges is exactly P/2) of the external thread has to be reduced a little bit (and vice versa for the internal thread). Also, major and minor radii are adjusted so that the real thread is guaranteed to remain on its own side of the theoretical parting line.

## Deriving threadlib Specs

||||
To simplify the thread profile, we want to avoid the rounding and replace it by a trapezoidal edge as shown in here (red: internal, blue external thread):
|
||||
We want to approximate the thread profile by straight-line segments as shown in the sketch in red and blue (internal and external thread, respectively).
|
||||
|
||||
|
||||
|
||||
It is clear that we have to match the pitch as accurately as possible. Therefore, threadlibs P is equal to the pitch in the norm (for G1/16: 0.907 mm).

It is clear that we have to match the pitch exactly. Therefore, threadlib's P is equal to the pitch in the norm (for G1/16: 0.907 mm).
|
||||
|

Then, we choose the pitch diameter to be in the center of the given tolerance range. For G1/16 this is (7.723 + 0.107/2) mm.
|
||||
|
||||
To explain the choice of r_major and r_minor for both external and internal threads simultaneously, we use the terms r_crest and r_valley. r_crest is the major/minor radius (external/internal) and r_valley is the minor/major radius (external/internal). The norm does not give limits for r_valley. But threadlib requires that the threadprofile covers *less* than 1 pitch of thread. Therefore, we arbitrarily choose a small but finite width of "valley floor" that leaves ample clearance to the parting line. For r_crest, we to take into account

The former is simple: We aim for the center. The latter requires a little math: We want our piecewise linear profile to remain on one side of the (true) BSP profile. Therefore, our crest radius has to be equal to the radius where the straight rising edge of the BSP profile touches the circle of the rounding.

## Adding Specs to threadlib
|
||||
|
||||
To get the threads into threadlib, we currently do the following:
|
||||
To get the threads into threadlib, we do the following:
|
||||
|
||||
- Add csv-file with original thread specs in design (e.g., "newthreads.csv")
|
||||
- Write an awk script (e.g., design/newthreads.awk) that translates this .csv file to tabular threadlib specs
|
||||
- Modify Makefile: Add a line like "cat design/newthreads.csv | awk -f design/newthreads.awk >> design/THREAD_TABLE.csv")
|
||||
- design/autogenerate.awk will translate the resulting THREAD_TABLE.csv into the final THREAD_TABLE.scad (same as the .csv but with added quoting and bracketing).
|
||||
- Tabulate specs as given in norm => design/newthreads.csv
|
||||
- Write design/newthreads.awk => translates design/newthreads.csv to tabular threadlib specs (see next step).
|
||||
- Add instructions to Makefile:
|
||||
`cat design/newthreads.csv | awk -f design/newthreads.awk >> design/THREAD_TABLE.csv` Now, `make` will automatically run the script.
|
||||
- design/autogenerate.awk will translate the resulting THREAD_TABLE.csv into the final THREAD_TABLE.scad (same as the .csv but with added quoting and bracketing). This script is already there, you should not need to modify it.
|
||||
|
||||
Furthermore, we should extend tests/test_table.awk to test our newly created threads. The very minimum is to add a test for the thread angles. Perform the tests by running 'make test' in the top-level directory or 'make' inside the tests subdirectory. If it prints "TESTS SUCCESSFUL" you are probably fine. Note: If you have a thread spec that is not tested at all, the tests will fail, too.
|
||||
The format of THREAD_TABLE.csv is:
|
||||
|
||||
`DESIGNATOR, P, Rrot, Dsup, dr_0, z0, dr_1, z_1, dr_2, z_2, dr_3, z_3`
|
||||
|
||||
The meaning of these values is explained in [Design of Threadlib](DesignOfThreadlib.md).

*lilo-tapers*: To make the tapers, the profile is scaled-down at the ends. We need to know where the profile is scaled to (center of scaling). We solve this by specifying the radius of rotation for extrusion Rrot explicitly and subtract it from profile (profile holds [dr, z] instead of [r, z]). lilo-tapers are then created by scaling towards dr=0.
|
||||
|
||||
*Overlap 1*: We could include P in profile by requiring that profile extends over exactly one period (i.e., P). However, this would result in a helix where neighbouring periods would exactly touch each other. This leads to rendering artifacts => P is stored seperately and profile is *required* to cover *less* than a period.

*Overlap 2*: But hey! Dsup = 2 * Rrot, no? In principle yes, but in that case thread and bolt would *just* touch => rendering problems. But we could implicitly assume that Rrot is simply 1% smaller than Dsup / 2 for external threads (and 1% larger for internal threads)! Yes, we could. But we decided to make that choice explicit rather than implicit.

I.e, the code is run for every external thread.

Finally, we have assured that every thread is tested. A thread that is not tested at all is considered a FAIL. This is done via two match-all rules: The first initialized the variable 'tested' to 0. The last verifies that it has been set to 1 by one of the test. If it is still zero, this particular thread has not been tested at all.
