Modeling of a flute by scanning volume removal

3D Design
1

Hello

I want to model a flute of a cutter or drill.

This machining is carried out with a grinding wheel moving along a helix curve.

In order to model the volume as close as possible to reality. I created  a volume (grindstone) and a helix curve as a trajectory.

I have difficulty positioning the volume for the removal of material. Anyway the result didn't make sense in relation to  the curve... The result does not match the "stl" model generated by programming software.

Attached is an stl file of the volume to be made on solidwork and a sldprt file of my material removal test.

Thank you in advance for your help.

Kind regards 

JB

HelloJean-Baptiste Grolleau,

Here is my creation without taking too much of a headache. (SW 2020 SP4)

... I hope I helped you a little ...

Thank you A.R, but it will be too simple :). 

If you look at the stl file you will see the complexity of the flute modeling grinding.

Yes indeed,

Are you looking for a perfect detail?

Better to go and find it in the appropriate sites So!!

Good luck then...

I am looking for a detail that is very close to reality indeed. That's why I use a scan material removal with a volume. in order to model the actual displacement of the grinding wheel to obtain a very close result.

Which site would be more appropriate to advise me on the modeling of this kind of shape with solidworks?

Thank you

JB

Hello

There are quite a few options in volume scanning. Including some that allow you to keep the tool in a certain plan (surely your need).

It is also possible that the wheels used to make the drills have a rather particular geometry (to avoid tool tailgating..)

Being in 2020 I can't help you more. A neutral file of your final volume and tool body would allow everyone to help you.

Hello

I'm bouncing back on that, but can the tutorial below help you?

Not having SW at hand, I can't see your files, but I guess that's what you want to achieve.

Hello everyone and thank you Hubert,

Thank you for your answer, that's what I want to do. however this function does not work in my case...  

Solidwork does not model the expected result... Flute shape and output don't correspond to reality and bugs...

Hello @jean-baptiste.grolleau 

In the demos I saw on the subject, we always use a cylinder either with a flat end or a semi-spherical tip.

So no propeller on the tool that will remove the material.

This is understandable because SW will have difficulty working with the edge of a cutter. By the way, all the CAM programming software I know works like this

Kind regards

Hello @Zozo_mp ,

Thank you for your answer. I do not know if my explanation is clear enough.

The volume that will remove the material is a full and complete cylinder that moves along a helix.

Solidworks can't model the result, which should be a helical flute (see my first screenshot).

The Sweep Volume Removal function only works according to the example of @Hubert and your explanation.

In short, I don't see a solution for my case with the removal of volume matter by scanning...

I thought of using a swept boss and then doing a combine to subtract the generated volume from my main body but it is not possible to do a swept boss with a volume (and if I do it with a sketch the result will be different).

I think I'm within the limits of solidworks to model this shape...

I'm not the type to give up but now I see no more solution...

Hello

A v2020 model that must correspond to what you are looking for (I didn't have fun trying to use the propeller or the profile of the STL: the pitch is not the right one and it is possible that the tool is more complex than a simple radiated grindstone).

 

The secret is here (the choice of the plane perpendicular to the axis so that the tool doesn't do anything while following the helix):
