opinions on technological quotation for turning (verification)

About the post #53 and that method to make a hole, but does catia not allow to make a hole directly from a floor?
with solidworks you have various methods to do it (draws on the xy plane and cuts in both directions, create a tangent plan to the curve and cuts, make a cut in revolution drawing on the section plane) and in the cai that is a high-end cad that you make the supercazzoli for the shuttles you can't do it? I don't know.

 

[mcbramby]

the software(or the professor) does not admit the definition of the drilling axis orthogonally on a curved surface: I define an addition of local material to be able to obtain a flat surface on which to define the hole

from where this statement comes...... always from prof.... or among you at university?? ?
we are talking about catia v5...... .

Unfortunately, I think that in addition to having a few notions of drawing, I don't think you've ever done a class of v5 :

Who teaches you this cad??? do they let you download and then arrange??? ? see that it is not a videogames:


I suggest you contact the noble professor in these sections that he created, at a price "abordabilissimo" , a great course of v5 casket that will surely help you to see many things , especially settings and examples of use of the commands .......

then use the forum with direct questions about things that are not clear to you, but if you read the manual (I bought it x curiosity and it is done very well, better than that of catia) , you will not have so many questions after......

you have to start chewing a little caia x using it otherwise you lose yourself in trivial things, and risks that people then don't help you because if you don't understand at least a minimum you can't try to do more complicated things................ .

Now you slowly read all posts, there are a lot of tips that you may not understand x rush to do ............ and then try to put together a decent table

do an a1 or a2 with at least the main view (where you see that it is all a cylinder , and where the holes are held) , and its section , try to quote with the idea that was given , then maybe you also put an isometric view............... and then show it to the post .................... .

I saw my first cat's demo a few years ago, turning on unix and the computer was as big as a washing machine. the demo they always showed was the simulation of the deformation for the impact of a bird on the muzzle of a super sabre, a hunt of the dassault .... of the late 900, the holes made them in suits the possible ways. Now you say you have to create a plan with an offset as if you really do it with the drill?! I'm amazed, less bad I didn't buy it ( actually I couldn't afford it)

 

[mcbramby]

...... Perhaps it is not clear from my post, because I have not written it, but the course of prof.nobile (I think it was called so or the noble) is a pdf file with explanations and illustrations ....................

for the speech holes...... (x never to say seen and done something like this)

 

[marcoevolution]

However I confirm after reception by prof: "I cannot define the center of a hole on a curved surface ergo I must add on site the material"


may seem/are obsolete processes
are wrong

Unfortunately I do not care now because the 13th I have the exam and since it is my professor to correct it I have to do everything according to his indications

Who teaches you this cad??? They let you dump him and then arrange?? ? ?

It was kind of like that!

 

[MassiVonWeizen]

However I confirm after reception by prof: "I cannot define the center of a hole on a curved surface ergo I must add on site the material"

be aware that all cncs then work ass barrels when they have to make holes on the curves.
However by reasoning from the first media: if I know the diameter of the particular (d1) and know the diameter of the tip (d2) my center will be (d1/2)+(d2/2); with the tip I touch the tangence of the detail and then I move the measure calculated... and voilà the center of the hole on the curve.

It is however inconceivable that in an incui school one teaches to become designers one does not teach to use a cad and that this is the one most indicated to the course that is attended and that above all it is common to all.
it is like teaching a pizzaiolo geometry of the focaccia, temperature of the coal oven, power supply for fast customers, but do not let him pull some dough for air.

If you draw a cylinder instead of the hole and do a boolean subtraction to the prof it suits him? I think he catches him easily

the maximum I can do is define as circumference the geometry to be extruded to create the flat surface on which to apply the hole

However I think that besides criticism of the logic of the required operations, the quotation goes well

I thank you infinitely, as always you are my salvation

a quotatura vada bene

if you refer to post design #56 I'd say no. if you have set it up good for you

 

[mcbramby]

Good examination

Let us know how it went...

 

[Utente cancellato 70856]

the software(or the professor) does not admit the definition of the drilling axis orthogonally on a curved surface: I define an addition of local material to be able to obtain a flat surface on which to define the hole

a)generation of a xy plan offset at the limit of the outer radius of the piece
(b) processing of a circumference of a diameter lower than the hole to be performed and bound by the general plans
c)extrusion of circumference for 1mm
d) application of the resulting flat face as "support" for the definition of the hole
e) application feature hole

But as you did, I'm a forum.
You made a fool of yourself
do a sketch and then you line the hole, it takes two seconds

Manca thing?

I'm actually posting random doubts these days...it's still long to get to 13!! (examination date)

I honestly didn't understand how he did it!

 

[MassiVonWeizen]

read what I wrote in the next post

I honestly didn't understand how he did it!

look that the phrase of motocad about how the hole was made refers to you; then gives you the solution

 

[Utente cancellato 70856]

If I don't erro, did you do the top floor tangent to the surface, right?
Now you do a sketch on that plan then
click on the hole command click on the point then on the plane, set larg and prof of the hole ok done

 

[mcbramby]

the point in the sketch can also not do ..... depends on the orientation of the hole .
if the hole is parallel to an existing plane just do the hole above the floor, then edit the hole sketch and place it.... .
If you want to edit the distance from the plane (which goes to position us tangent to the circle) , creating a formula that is the radius of our piece to drill...... so if x case the hole is threaded, if change the diameter of the piece automatically parameterizes ................ just double click on the plan go or on the quota or the form that opens with inside the value of the quota , button dx on the value .... the first item is "change the formula" click on it and opens the form of the formula , touch the object revolution and you will see that the odds that you used to build it.... including the ray where you will make the hole , cliki above and now confirm .... that sweated if I showed it, it took 10 seconds... ............ obviously you can use it with any quota......... is very useful

Sorry I didn't understand, I thought it was these days.

Now you do a sketch on that plan then
click on the hole command click on the point then on the plane, set larg and prof of the hole ok done

so I would contravere to the indication of my professor who anticipates an addition of material on site

no did not make any plan (in the tree there is not) ....... ) which is not executable then also passes on the other side (entry hole) .......... unfortunately x my "tastes" not to be done......... better to create the plan from above x that you could change it by making a blind hole or another type (if it is enlarged or conical) and if you do it as the example one touches you to do it again ................... I do not want to criticize anyone's susceptibility
