ball burnishing process on herringbone gear (newbie)

[JEK5019]

good day all -

you'll have to pardon me as i have '0' experience with machining. however, i am beginning some designs that i intend to manufacture - and need some help in clarifying.

i have created a herringbone gear. i would like to the finish to be highly polished - like ball burnishing.

what kind of machines will this require? a 4-axis for the herringbone?

i want the edges of the herringbone gear to be sharp (like the original design) will ball burnishing wear down the edges?

thanks in advance!

It's worth reading up on machining processes, it will inform your questions.
You will need at least 4 axis for a herringbone gear, provided your machine is rigid your part will be as it is in CAD, you control the finish with the options in CAM.
"Polished" finishes are achievable with machining, the finish is a function of how fine the finishing pass is, the finer the cuts, the longer the time taken.

thanks again nick -

i wasn't aware that type of finish could be achieved with machining alone. i'll look more in depth on the machining processes.

If you've not already seen it, and odd gear designs interest you, you might want to check out Gearotic - http://www.gearotic.com/

It lets you design a plethora of gears, and can output the required code to machine them.

i designed the gear in fusion 360 - and i'm interested in figuring out how to sort the output code from withing the software.

silly question - but if i manage to create the output code from fusion 360 - is that code universal? or is it unique to both the software and thr machine of choice?

nice - thanks - this is a great resource!
