Hi:

 I answered on the other thread. I dont see any thing coming out for bevels in future other than perhaps better 3d models of them ,
which I do have planned. I hope to redo all the gear modeling to better standards for 3d printing as well as add worm gears
,acme screws and such. Bevels have always been a problem, they require a pretty special machine effective ly and I
just dont see any solution as yet that makes sense.

Hi:

  Yes, bevels cannot be machined by the 3 axis machining, and an engrave option was not developed .
The problem is that I see it as one of those problems not solvable in a useful way.  Its very hard to
get around the way bevels are actually made and the axis control required.
   Ive investiga ted code wise methods to do them as simple engraving s, just normal 3d milling for that
option basically, but your left with a bevel that needs a lot of work unless it takes days to machine with a
small ball endmill. Even then the face surface isn't likely to be great.
  The only way to do bevels at this point is to load a 3d model of one into a proper cnc software to generate
3d milling paths for it. Depending on the bevel I think it'd be a not particula rly nice experienc e making one
that way. Im thinking 3d models will be the normal way in near future given the strides they are making.

Guys, nice topic. Any changes ArtF regarding bevel gears cutting? I bougt my licence in Feb 2012 as i wanted to make some bevels... Now after almost 9 years i'd love to see working solution:D

Got question: i've created my bevel gear and wanted to use "Send to 3 axis" option. Then 3-axis CNC tab appeared with my gear on the grid. I've set my tool as 1mm dia endmill, set over pass, spindle parameter s and Z-Dn/pass (0.1mm).  
Then in 'Job Settings':
- what is actually 'depth'? Initially i thought it is similar Z-Dn/pass but now i'm not sure
- tabs - are they to hold material, like bridges?

Worst thing: in 'Output Options' all the icons are grey out but one - 'Engrave'. When i hit 'Engrave' message pop out 'Engraving not released'. So how to activate the options here? So far i can do nothing further.

Hi Dave:

  If you can figure out the rules about the sizes from the examples of the dxf's in the Gearotic
spoke folder you can add some yourself, the program will see them on startup. That having been said
its not highly intuitive . Basically it scales what you draw so you just need to have an extent of -1 - +1
in sizes. Im not aware of any others..

I have Gearotic and a couple of other gear design programs. They can all do the gears just fine but I'd like to get a bit more creative in designing more visually appealing spokes. Can anyone suggest an app for that ?

For anyone who is intereste d in mechanica l mechanism s, here is a link to a very large PDF book : Mechanism s and Mechanica l Devices Sourceboo k by Neil Sclater. It does show a copyright so I don't know what the legalitie s are of downloadi ng this.

http://160592857366.free.fr/joe/ebooks/Mechanical%20Engineering%20Books%20Collection/THEORY%20OF%20MACHINES/Mechanisms_and_Mechanical%20devices%20sourcebook%205e%20NEIL%20SCLATER.pdf

I also found a very old ( 1930 ) book called Ingenious Mechanism s by Franklin D. Jones which seems to be available from a number of sites. There have been some updates in 1936, 1951 and 1967. I haven't spent a lot of time comparing them but they appear to be updates, not additions to the original.

I was going to try some tutorials on Fusion 360 and came across this video. Scrap that plan. I think a number of people here do use it so you might want to have a look :
