Undercut machining.

[cadist]

I saw your drawing winnie coooooooool down. why are you getting so hyper. I said earlier also

I know it will not cut all the material but whatever extent is possible.

Again thanx see ya tomorrow.

[cadist]

Thanks michael I saw your out and this is what I was getting using a slot mill will not allow me to keep shaft dia as 20 ( you kept 14.99) that makes risk of shaft rubbing the surface.

BTW Thanks again michael.

Nadeem .

OK

See my file in a couple of hours

Nadeem,

 

What is happening is that it is calculating to that tool( slotmill) but verifying to your tool just as you descibed. I but blocking surfaces (level 16) in the recceses so that the tool will not enter more than 2mm. Doing something like this allows you to Verify to your tool and also write out an STL. I then bring the STL in Rhino and do an overlay with the Design part STL so as to check for a gouge.

 

Please have another look.

 

Thanks,

 

Mike

Cadist,

Ok, well I got to admit that I am also a very big fan of verify, but it is not going to hold me back from cutting the part. As Winnie wrote you should be able to customize your tool for verify, myself have never been in the situation were that was needed.

OK.

Here we are .

Ahemm !

Nadeem .

Look on my file UNDERCUTWTPGOOD.zip with custom tool + verification .

I hope you`ll like it .

 

Winnie teh on his dirty ways

[Teh Bear without Brains kinda idiot]

Nadeem .

Have you seen my file ?

[Mike Whitten CAD/CAM Contractors]

And mine?

 

Nadeem, both of our programs do as you were asking.

 

Thanks,

 

Mike

[Teh Bear without Brains kinda idiot]

Yes !

 

What Michael sais .

 

Winnie teh beer is 4 bear .

[cadist]

Hi, every one again,

Sorry Michael I got to accept I didnt give a proper look to your file, and yes it is helpful. I got a new technique, thanx.

And winnie I saw your drawing also, thanx again for cooperation.

[Teh Bear without Brains kinda idiot]

And what about me ?

 

It`s not good ?

 

Teh abused

[cadist]

Oh my god winnie I said thanx. it is good technique. I really admire your efforts. You did good job.

[Teh Bear without Brains kinda idiot]

Nadeem , I would in your place be catious with shank 20 ,you better define it 0.2-0.3 mm greater ,just for any case .

I made a gap between tool and a part .

Good luck and sorry ,if something got wrong .

Loneliness is my hiding place ...

[cadist]

Hey winnie you know with this topic you pushed me from 186 to 200, I really don't believe in post count but now since I crossed 200 mark ( may be the only person from this side of globe) What do you think which type of avatar should I opt for. Every one can reply.

[Mekanikal]

Hey Nadeem congrates.

[Teh Bear without Brains kinda idiot]

Nadeem , I think look inside yourself and dig out your real one .

Something funny and joyful ,as you soon will see my avatar .

I want to say sorry for my tone and hyperity and wish you good luck in your work and all .

Come here just for fun ,this place is great !

[cadist]

Hey winnie congrates for that avatar but it is the same one used to be displayed at your signature area.

[Phil Orenstein]

Hey Nadeem, just put my avatar up today!! Your turn now! What do you guys think? What do you think it is and how do you think I created it? I think this might be a good challenge for our great gurus!!

Phil It is great

But But But... sorry to disappoint you that shape is basic command in 3D studio max under extended primitives called Knot You have kept P value as 3 and q value as 2.

 

Correct me if I am wrong (less chances buddy) animation was my primary interest.

BTW you have shown me the way man .

[Phil Orenstein]

Amazing, Nadeem!! For so long, since I created that as a surface model years ago(almost geometrically perfect) I had been trying to decipher the holy grail of this primitive, torroidal knot. No one I knew could venture a guess as to how to create it from scratch. I do not know 3D Studio, but how do you think they might have created created it in the first place? As a free-form or as a mathematically accurate swept surface? What do you think good buddy?

 

BTW I knew that I would get answers to this odd geometric problem only here!!!

 

Phil

[cadist]

It is a swept surface, the "p" and "q" value define the number of curves in u and v directions. And you know what you can also define an eccentricity value which will create a buldge at one side of your knot.

[Phil Orenstein]

Nadeem,

Mind if I ask what are "p" and "q" values? How are the original 'across' and 'along' contours created, given the across curve is a simple circle?

 

Phil

[cadist]

umm.. I don't know the actual algorithm behind the software but the across curve is a simple circle and the along curve is a mathematical equation which consist of variable as the size(which is the raius of bounding sphere of knot) and then these two variables p and q, which defines the path of along contour, you increase the number and there will be more twist in the knot. If you want more details got to wait for a day...

[Phil Orenstein]

No that's fine. When ever you have a chance. Just curious! It took me almost a week to create it years ago in Acad surfaces for a scultpture project. I don't think there's a way to do it in Mcam ecxept by importing in the wire along curve. I didn't know it was already created as a primitive. I was thinking it could be done with Mathematica, what about Rhino?

 

Phil

[cadist]

You did it in Autocad great
