generation path cut from .dxf files

[Steel Saviour]

Hello everyone, I'm a mechanical engineering student with a predilection for aluminum filing:biggrin: .
I am delighted with the dynamic automodellism, precisely I try to self-build what I can.
in this period my uncle allowed me to delight with the machine tools of his company (tornium and manual milling), moreover today he proposed to try to cut some frame with the cnc; m'han said that it simply serves the dxf file of the component to generate the path machine.
the problem arises at this point because I don't know exactly what it takes: three views are needed or a "frontal" is enough, the views are quoted or the program is able to recover the size alone?

These are some of the pieces that I am drawing and that I would like to build:

Hello everyone.. .

Any advice?

I ask that I do not understand anything about cnc, so I cannot answer, but I ask myself: does the uncle know what to feed his machines? Can't you ask him what he needs to handle the processing?

Bye.

Hi.
I'm sorry, but your request is a vague little,
if you give more info would be better,
What are you doing? ...or better what language should be used? ,
from the images you have attached are simple to realize
with the project2 (Selca )....
If you do the harvests and quoti everything you can progress on the machine. I know the language of your cnc.
or from tables 2d carry the .dxf,
of course only the profiles,
and load it in the cnc.
the ways to get to do... are endless. . .
Hi.
peace and well:smile:

My uncle is at the top floors , I spoke to the boy who usually works at the car; Unfortunately, being he engaged, I could discuss only at a time of pause; Moreover the company is far from home and I find it a little complicated to go to ask for more information.
In any case it is not a big problem, hurry I do not have; if I can get the files ready better, otherwise next time I ask for delucidazioni :wink:
The last option you mentioned seems to me the right one: I have to bring him the .dxf file of the 2d tables and, from what I understand, no quotas are necessary.
the question is about the table: just a single view and the directions on the depth of the excavations are inserted directly into the machine or the .dxf must contain all the views necessary to define the component?

 

[vmirko]

if I have to do such a job to me would suffice the dxf 2d and a drawing with depths,
I'd pass them in the cam and from there to the car.
This is what I would do,
Then it depends on your uncle if he has the possibility to use a cam or put the dxf directly in the car.

It's usually just what I wrote to you at first.

Hi.
you can stack a dxf or dwg in the sw cam
perform processing according to design geometries
if you have prob you create path containment surfaces
and impose values in z

this applies to the two jpeg attached
for the third one can do the same thing
but you have to work in sectors because you have different h

for the holes the speech is a different moment
a quoted table and the operator on the machine
according to a "0" xyz establishes an execution program

but the prob is not so much in the feasibility of processing through geometry in dwg or dxf
seeing jpegs is very likely that at the end of processing
you will have embarkations
perhaps before performing mecc processing it would be appropriate to ask
how to perform all in series of operations to avoid this prob
Thank you very much

.... try to cut some frame with the cnc; they told me that it simply serves the dxf file of the component to generate the machine path....

Hi.

I'm sorry, but to cut, you mean to cut? or laser cutting?

Hi.
p-h

 

[Steel Saviour]

After a little break for the exams, I'm going back to the question.

@ preparation-h: I speak of cutter 3 axes;

@ shiren: I have understood some things but I have doubts about others (weird if I feel ignorant :biggrin: ):
When you talk about containment surfaces, do you mean that the various areas that present the same depth of excavation are isolated on the machine?
for embarkations do you mean the deformations that can undergo the slab during the passage of the mill?

for holes I can simply delete them and do them in a second time with manual milling.

when you talk about profiles (like the side) you mean the single side view, and not the canons three views? I know: ).

Hi.

Your uncle knows you're about to destroy a three-axis? ...andhehehe. . .
cmq there are ceh software called cad/cam that according to the language in which your machine speaks can generate the optimal cutting path: you can do it as you want...or (recommended choice) optimize the cut therefore also with the management of the solid...etc...etc.. .

...documented a little...the beauty of having these machines for pleasure is also in being able to document and learn how to make them do what you want;-)
