Is this just for show (simplified) or a precise model for manufacture?
Can you attach your ipt file of what you have tried so far?

Hi JDMather,

 

Thanks for the superfast response.

 

this is will be a manufacturing model so we need it precisely as indicated from specifications.

 

I am still starting to create the ipt (see image) and I found it to be very challenging. 

 

Thanks again for the help.

 

 

regards

Jerome

When you have more than a cylinder done - post back with your attempt.

You might take a look at the twist drill here http://www.cbliss.com for some ideas on how to get started.

Hi jeromecastaneda,

 

Here is an example that you can use as a guide. Just use the browser to follow how the features were made. You'll need to pull the  the End Of Part marker in the browser down to expose the features in this model. I've rolled it up to make the file smaller for downloading.

 

I didn't see where you mentioned the version of Inventor you're using, but this file was created with Inventor 2010, so you should be able open it judging from your screen shot.

 

I hope this helps.
Best of luck to you in all of your Inventor pursuits,
Curtis

I appreciate your help Curtis however this is different from the pdf drawing.

 

Again thanks for the help.

 

 

Cheers

Thanks JD

 

are you referring to the iTwist Drill.ipt?

 

I'm still visualizing how I can use the parameters in the pdf to create the helix profile cut. 

 

Do you have a suggestion how I can match the section profile for helix against the pdf drawing data?

 

 

Cheers

Jerome

Hi jeromecastaneda,

 

Indeed it is. The attached model was just a file I had on hand, but if you examine the fluted loft cuts and how they were made, it should provide some insight into how you will create the flute cut features for your part.

 

I hope this helps.
Best of luck to you in all of your Inventor pursuits,

Hi JD,

 

Can you check the attached part file that I've created? I'm not sure about the section C-C and B-B based from the pdf that I send as well as Detail D.

 

How do you smoothen the transition between the shank and cut length?

 

Thanks a lot

 

Jerome

Sketch Det_D is not constrained.

You might want to read this document before continuing further

http://home.pct.edu/~jmather/skillsusa%20university.pdf

 

For the rest of the geometry - it will take some time for someone to go through and verify that it is correct.

I would be very careful about the Coil command (it could be right - I haven't checked yet) as it doesn't necessarily return the same geometry as would be made in the manufacturing process of this part (a moving cutting tool along a path - refering to  the manufacture of this part, not the fact that it is itself ultimately a cutting tool).
