Drill Bit ?

[Corndog]

Has anyone made a drill bit in Hex. if so could you give me a pointer on which method you used.

TY

Maybe start with the helix, add thickness and fiddle away from there.

Hi Corndog,

Try this;

(1) Create a cylinder, then 2 other cylinders about 25% smaller. (Picture #1)
(2) Boolean off the two smaller cylinders and extract the curve from the top of the remaining object (Picture #2)
(3) Get rid of the cylinder, put the curve at the origin. Select the helix tool, shift click to start it @ 0,0,0 and tab to the numerical entry. Create a helix with start/end radius=0.1, height 75, slices=2 and edges=64. (Picture #3)
(4) Use sweepline/Irregular sweep (Picture #4)
(5) Close the open ends of the sweep, fast extract the top face, select the face & convert selection to points. (Picture #5)
(6) Numerical entry : set selection size to 0,0,0 (Picture #6 - next post)
(7) Stick a shaft on the bottom - you may want to do something better than me where the shaft meets the drill spiral. Smooth once (Picture #7 - next post)

Hope this helps

Miles..
First off thank you so much for taking your time to help a stranger.
And second that is just awesome.. I will post my result

Thanx for sharing your knowledge.

Master!!!

[Corndog]

Ty again..
I can apply that method for so much

[Davidoff]

Thx Miles, a very good demonstration.

[whkguamusa]

good way to do it

thanks

[Thomas]

Yes, very good demonstration of one way to do it!

[MilesW]

Corndog - Looks good

Thanks to everyone for the comments

[Andreseloy]

I cant surpass the 3 step, is not clear for me! Some explanation is welcome!
Thanks

Step 3a:

Press F1, Select the curve. In Object Properties|Position click the red box and enter 0 (tab) 0 (tab) 0 (validate).

The curve is now positioned at the origin (0,0,0)

Step 3b:

Select Lines|Helix tool. Press (tab). Enter 0 (tab) 0 (tab) 0 (tab) (validate). Now (tab) 0.1 (tab) (validate) to set the start radius to 0.1.
Now (tab) 0.1 (tab) 75 (tab) (validate) to set the end radius & height
Now (tab) 2 (tab) (validate) to set the slices
Now (tab) 64 (tab) (validate) (validate) to set 64 edges and complete the helix

Step 4:

Click on the curve to select it.
Select Surface Modelling | Sweep line tool
Click on the helix

If the "Irregular sweep" button is not selected in the Tool Properties window, then click on it.

This should produce picture #4

Hope this helps

Very kind and quick help!
I will try and comment later!
Thanks

Having a dreadful problem in trying to do the booleans for this tute. I just can not get the small diameter cylinder to boolean out of the larger. Get messages that things are wrong--or another tool inserts itself. Not having a problem trying to boolean with other objects! I guess I am doing something wrong but after lots of attempts I have no idea what.


Well I tried doing what I thought was a no no, I did not use validate,apply or enter through that whole booleaning exercise! And it worked!!! Wheres the crystal ball to tell you should not do what you should?

[Corndog]

bwtr

actually I had never used a boolean feature before this mini tute and I did exactly what the manual said to do for the boolean tool and it worked fine... So as far as a Crystal ball goes, unless the manual is in there you do not need one.

[bwtr]

I am back on this tute. Again!. I am lost at Miles's Step3b. It needs some "filling out" to be clear to me. What do the 3 "now" items refer to? Sorry if I'me thick but the exercise seems to require an imagination of tool usage light years away from "normal?" humans like me. I just love the ideas of Hexagon but the more I get involved the less I seem to know! Am I too old or are others having mental difficulties?

[Corndog]

Bwtr did you see this post a little was down by Miles:

Step 3a:

Press F1, Select the curve. In Object Properties|Position click the red box and enter 0 (tab) 0 (tab) 0 (validate).

The curve is now positioned at the origin (0,0,0)

Step 3b:

Select Lines|Helix tool. Press (tab). Enter 0 (tab) 0 (tab) 0 (tab) (validate). Now (tab) 0.1 (tab) (validate) to set the start radius to 0.1.
Now (tab) 0.1 (tab) 75 (tab) (validate) to set the end radius & height
Now (tab) 2 (tab) (validate) to set the slices
Now (tab) 64 (tab) (validate) (validate) to set 64 edges and complete the helix

Step 4:

Click on the curve to select it.
Select Surface Modelling | Sweep line tool
Click on the helix

If the "Irregular sweep" button is not selected in the Tool Properties window, then click on it.

This should produce picture #4

Thats the one that worries me.

[MilesW]

Hi bwtr,

Here's an expanded version of the 3b step - hope this helps

Miles

Step 3b:

Select the Lines|Helix tool. The tool properties panel displays the values of the centre of the helix.

Press (tab) to move into the X position numeric entry box of the centre values. Enter 0.
Press (tab) to move to the Y position entry box, enter the value 0
Press (tab) to move to the Z position entry box, enter the value 0
Press (tab) to highlight the the Apply button, then press (validate).

On the screen, the centre of the helix moves to position (0,0,0) and the tool properties window changes to show the helix radius value.

Press (tab) to move into the radius value entry box & enter 0.1.
Press (tab) to highlight the the Apply button, then press (validate).

This sets the helix radius to 0.1. The tool properties window changes to display the End Radius and Height values.

Press (tab) to move into the end radius value box & enter 0.1.
Press (tab) to move to the height box & enter 75.
Press (tab) to highlight the the Apply button, then press (validate).

This sets the end radius & height. The tool properties window changes to display the Slices value.

Press (tab) to move to the slices value box & enter the value 2.
Press (tab) to highlight the the Apply button, then press (validate).

This sets the slices value. The tool properties window changes to display the Edges value.

Press (tab) to move to the edges value entry box and enter the value 64.
Press (tab) to highlight the the Apply button, then press (validate).

This sets the number of edges of the helix. This is the last parameter of the helix, so now press (validate) to exit the helix tool.
