Accepted Drawing Formats

A print is still the best way to communicate important data and inspection requirements from person to person for any product. However, CAD (Computer Aided Drafting) files are the best way to communicate with the machine tools used to manufacture parts. Alloy Metal Products has capabilities to machine from CAD files. The CAD files are converted to CAM (Computer Aided Machining) language that our Machine Tools understand. In order to accommodate both entities of the manufacturing environment for the most efficient use of our technologies, (and the quickest turn around times for your product) we have developed the following guidelines.

Quoting:
In order to quote products as accurately and quickly as possible, use a CAD file with basic dimensions, part and material descriptions, finish requirements such as plating, heat treatment, and inspection requirements. The preferred format for quoting is Acrobat reader files (. pdf). AutoCAD vers.13 or older (.dwg) and finally, .dxf files. 3d wireframes or surface files in IGS or DXF formats are acceptable but require extensive analyzing to properly prepare a quotation.

Any detail that is important to the function of the part should also be noted and described.

Manufacturing:

In order to expedite the machining process and to simplify the analysis of complex geometry’s, a 3 dimensional wire-frame model of your part is best. We can read and machine files that range from 2 dimensional wire frames to solid surface models that require 4-axis machining.

The preferred format for all data files is *.igs or *.stp and all dimension files is *.pdf (Acrobat reader files), *.dxf , or *.dwg (AutoCAD files).

If the part requires 3 or 4 axis machining, a surface or “solid model” should also be included with the 3 dimensional wire-frame. To machine complex surfaces a “Surface or Solid Model” is best. If you can’t generate a surface model then Alloy Metal Products can do it for you.

Alloy Metal Products can read the following data formats:

  • .pdf (Acrobat reader files with text and dimensions)
  • .dxf (DXF 2D wire-frames and files with text and dimensions)
  • .dwg (AutoCAD version 13 wire-frames and text with dimensions)
  • .igs (IGES 3D wire-frames and surface files) .cdl (CADL) .csf (CSF) .des (DES)
  • .fst (FST) .nca (NCAL) .sat (SAT) .spa (SPAC) .sup (SUP) .vda (VDA) .asc (ASCII)
  • .x_t (parasolid)
