UGNX: Twist Drill Model

UGNX: Twist Drill Model

RE: UGNX: Twist Drill Model

What version of NX are you using?

To an Engineer, the glass is twice as big as it needs to be.

Hi Jhon,

I am using UGNX7.5.

Thanks in-advance.

Hi Jhon,
Thanks you for quick response.
And, clear with flute creation. And, I need to make flute relief with parametrically ( see attachment), when ever changing Drill size, Pitch that flute relief will be update automatically. As well as need to maintain that overall flute height until that relief.

Thanks in-advance.

RE: UGNX: Twist Drill Model

I was just roughing it in as I don't have the detailed specs, only what's shown in the 'Machinery's Handbook'.

RE: UGNX: Twist Drill Model

Why do you need such a level of detail in the model of a twist drill? For what purpose will this model be used?

Need to create master model and to create child part with associative drafting.

RE: UGNX: Twist Drill Model

Are you in the business of manufacturing twist-drill bits? If so, it would seem that you've already got the specs that you need to model a drill bit.

I need only in UGNX option to control that shape.

RE: UGNX: Twist Drill Model

This seems like a lot of work for very little return, particularly if you're not actually manufacturing twist drills. So to what purpose are you going to be putting these Drawings?

RE: UGNX: Twist Drill Model

It might be best using law curves. I was able to create a single curve that would mimmic the helix of a thread and the imncomplete threads. The equations of the thread are all driven by expressions and update to any size thread without and problems. It also uses less resources then other attemps I have seen.

I wish I knew enough math to give you the equations, but I really don't. It took me a long time to complete my thread model. If you needed a good way to model this sort of thing in NX then that would be the best way to approach it.
