Easy way to program hexagon

Hello there,

Is there an easy way to calculate/program a hexagon.
Like for example I need to program a hexagon for a piece and the plans only says "for 16mm wrench".

Thanks.
 
Lots of easy ways.
Are you looking for corner to corner dimensions? The machinery handbook has a nice section on Chord dimensions and formulas, and also some standard sizes of hexes already dimensioned out.
 
Draw it up frist. Drill the corners, drill then plunge an end mill just shy of finish depth. Write the code for finish shape then call it as a sub at whatever depth of cut you want to take.

Figure corner dims for a 1 mm (0.5 radius) hexagon with flats aligned with Y axis, and again with flats aligned with X axis. Save a sketch where you can easily find it.

Now you can solve for any width by multiplying each coordinate by the wrench flat dim. Saves looking in a trig book.

What control are you using? Some like the Okuma offer cycles to do this very thing.

Wow, lots of replies :D
I meant an external hexagon.
I'm on a Mazak using Mazatrol Nexus 2.
I assume it's best to use corner to corner x-y coordinates.
But I'm sure there must be a simpler way, no?
I mean, we bought a 300k machine, there must be a way to easily program a hexagon??

That's actually a pretty good idea
