created files for numerical control machines

[gexigo]

hello to everyone, sorry for the question perhaps discounted, but I have not much experience with autocad :frown:
is it possible to create files for numerical control machines such as pantographs etc? in this case how should I proceed? Is it difficult?

 

[gexigo]

I tried to open dxf files downloaded from the internet and this message appears to me on autocad 2009: no layer specification for this object. Line 20.
invalid or incomplete dxf input - deleted design.

pantographs read dxf (if well done.. . )
Maybe a line is missing in your dxf. Just add the layer definition. open the dxf with the notepad, it is only an ascii file.. .

mmmm... I opened with txt ... the dxf ... na parola ... :frown: I opened another one and goes, it is a simple square, I saw the annexed explanation of the ascii and I guessed to big lines the operation of the file... but I would like to know if to run a numerical control machine, like a pantograph, just draw what you want to get in autocad and save in dxf or there are special notices to adopt ... thank you in advance

My answer was mixed.
- add with the notepad the definition of layer to open the dxf that autocad 2009 tells you to be defective.

- to make a cnc processing, like milling or turning, or whatever, of the dxf you do nothing, because you do not, to say one, the parameters of number of past, depth of pass, speed of progress, etc.

- to make pantograph cut, the dxf is fine. how to do it, depends on the machine software. most software demands completely closed figures and without overlapping lines. for simple figures (e.g. square) is a trivial operation, if you have to cut out the coat of arms of the republic... well, you have to unleash us a little.

:redface
but the dxf could be useful to ki handles a mill etc. etc.? the basterebe only the design ke then will elaborate in reference to the machine (pass number, tool etc.) ?

He needs the design. if you give him a 2d in dxf, or printed, or hand drawn on the bread card, for him is the same. indeed, if it is printed and quoted it is better.. .

what is the dxf for then?

autocad dxf (drawing interchange format, or drawing exchange format) is a format for cad type files, developed by autodesk as a solution to exchange data between autocad program and other programs.

dxf, the acronym himself says, is a file of interchange between different programs. as a concept, no more or less id a step, an iges, etc.

Fucking tir, you got me on time! :finger:

I understand:

 

[sampom]

bhè, laser cutting (2d) and similar (so pantographs etc.) read directly the dxf/dwg.. those machines working on the 2 axes of the plan (of un piano). simply provide the file with the templates without quotas or indications, the machine will "follow" the contours lines.
for milling, turning and three-dimensional processing, in addition to the classic system of the quoted design that then the operator/programmer will have to "read" and rewind on the machine, it serves a solid model made by a cad 3d "real" (so not the dwg/dxf of autocad). then you pass to a cam program (which could be integrated into the cad/cam) that directly derives the tool paths; everything is translated into machine language by post processor.

greetings

Thanks marco :wink:
