Have you tried a .step file?

Give this one a try...

I will have a look at it..

AWESOME!

Sounds like a good project you have.
Happy to help, as always......I live on Featurecam....Sad, I know......:banana:

Good Luck~!:cheers:

Ah ha!!
Any luck with that part?

Sorry for the delay, work has been busy....

This will get you what you need.
It is not perfect, so you may want to play with the numbers some.
I used a 0.500 diameter endmill for this.
Let me know how it turns out!

Good Luck~!:cheers:

That is going to be a little tricky....

Here you go.
Two ways to do it.
Just adjust the parameters to fit your needs.

Good Luck~!:cheers:

Give PEEK a try.

Save your file in SolidWorks as a Parasolid .x_t this will solve this problem for you.
Or you can update to the latest version.
I can not remember off the top of my head what version had issues...

Happy to help!

You will need to use the "Curve Wizard"

See attached:

1st step will be to create curve from surface and then surface edges

2nd step will be to unwrap those curves you just made...

Here you go...I did not adjust any of the parameters just created the curves and made the toolpath.
The model you sent has some errors so please do not use my FM file for this part.
You should fix...

Ok I have the file open and the OD of the spiral is 0.906 inches...
Is this correct?

You should get some 2 flute and 4 flute HSS "High Speed Steel" endmills to get started.

Probably 0.250,0.375,0.500,0.750 diameters.

Those are the most common sizes.
2 flute for plastic, wood...

A bit of the code.
There is a ton...

N0101 (TOOL=01 PASS=01)
( MILLING: BEM .031 4F-ROTARY X )
N80 G19 G20 G40 G54 G80 G98
N85 M45
N90 G0 T0101
N100 G0 C10.501
N105 G0 X11.0 Z0.0157 M8

Yes....If, you are going strictly for Milling, and no Turning.

:cheers:

FeatureCAM is a "Feature Based" CAM program, that includes all milling types and tun/turnmilling...the milling side is, in my own words like a "PoweMill Lite" version.

PowerMill is a very powerful...

Please post your solid part and I can show you....
You have to make curves from the solid then unwrap the curves.

YES
Go with FeatureCAM
It gets better and better with each year.
And they are now a part of "AutoDesk"
Since that merger the software has gotten exponentially better.

USE THIS FILE....

This will get you what you want.
Just remove the G97 "S"CODE AND M13.
I just do a mill path with a tool as wide as the nose radius of my turning tool and there you go!

CHANGE THE...

I too, would like to have some input about this.

YES!
You are correct.

Do you have SolidWorks?

A function called costing under the evaluate tab.
You can setup all your parameters for that and the software looks at the volume of material to be removed.

Good...

Start off around 800 SFM
600 SFM is good too.
If this is true brass, and not alum. bronze.

You can go as high as 1600 SFM on a finish pass.

3056 RPM's at 1.0 dia. "800 SFM"
2292 RPM's at 1.0...

Go to options, addins, library, then scroll down to utilities, select Vortex Milling Calculator.bas

Good Luck~!

The default that FC puts into the thread height is wrong.
The minor for a 0.500-13 is 0.4225 nominal. and the thread height is 0.03725
If you plug these into FC thread mill you should come out...
