Good evening to all

In the company where I work, I have some drawings in which we have to make teeth.
I tried various programs to create the tooth profile and doing some hand calculations some things fit me.
Just insert module, tooth number, pressure angle and do all the software.
My problem arises when I have to verify that what has given me the software as a result is correct.
Is there any method that is used for verification?
I press that I only need the profile to export it to dxf or dwg and then create the profiling program with the cad-cam.

Thank you in advance for any response

Good evening.
 
but I can know how to dentate, if you use the creators there is no need for dxf, except to indicate on the drawings the teething parameters.
 
Bye. I normally use an excel sheet to have the dimensional parameters that allow to resist according to regulations the gears.
I then model the gears also I to mount them in 3d and make the drawings together in order to also verify the magnification.

I use it normally freecad con il workbench fcgear. is free and makes cylindrical and conical gears, racks and other things.

another possibility is to use a program that generates the profile to evolve.
free you have directly on me-bac. We had already spoken qui.

then there are in paid program that are kisssoft, mitcalc, and other stuff you can find in germany.

therefore,
Initially on the net I was able to find a sheet of excel called "mittcalc" by entering all the data generated the geometry of the tooth only that I found inconsistencies when doing hand calculations, I did not know if I was wrong or the sheet.
later through the company I managed to get the demo of kisssoft, which seems to me the only program that approaches the results, gives me the possibility to create geometry directly in solidworks.
I just need that certainty that the profile is correct, it also happens to have profiles with modifications on the addendum and dedendum and I go right into crisis.

certainly, with kisssoft do everything, direct export.
with freecad you have profile shift and head cut.

So you need the profile to give who's gonna bust you?

but it happened also that it was necessary to review the profiles of the teeth made by those who do it after the treatment of tempra. and then to generate the program we say "finish" we need to have the tooth profile

correct, we make special cutters with tooth profile

the general is uneconomic because you will have 1000000 types....module 4....with x0,1 x0,2 x0,123... .
But obviously it will have very large batches and therefore first to make the shape of the cutter and go of rotation and removal of truciole.
 
but then do you need the profile for grinding the tooth? But then the only control to do is the whildarber measure or the size with the rollers.. or check the total error consisting of using a sample wheel.. I don't know the size and modules.. Maybe I say festive. . .

exactly, working in the steel industry the pieces are so large and in very small batches that it is better to make the cutter or cuter.
with the results you get with free cad and various software.
How do you say okay? the profile is correct can we proceed?
in the drawing usually I am indicated z , m α ° etc...
 
inventor also generates tooth profiles or even the khk gears program, but I have never actually verified the accuracy of the profiles .. having always dented with the creators I never placed the problem!
 
for what is needed to me just check that there is no interference and that the game is compatible with the needs.
freecad is also used for 3d printing... clearly kisssoft has no comparisons and is the top of the range really and has all the world verifications.

exact, the evolving profile however is a geometry....and if you know the formulas to build it you have everything.
 
I have seen that the two programmes mentioned above generate the profile of a tooth and I presume they do it correctly, otherwise as you say you have to build it, I have not yet understood what forms we are talking about. .

I guess we're on module 30-40-50-60....space gears... steel setter.... 3 meters in diameter.
up to module 16-20 there are creators, expensive, even to plaques ... but if salts you pay also 20000euro and beyond the creator.
