We have been using Mastercam programming software since we first began programming CNC machines. Mastercam is the most widely used CAM software worldwide and remains the program of choice among CNC programmers. Mastercam delivers the most comprehensive milling and lathe packages with powerful toolpaths and techniques available to date.

During the design assistance process, customers will be working with design personnel that have first-hand experience in the manufacturing processes offered at API/AMS. Designing products around customers needs while offering the realities of the actual manufacturing processes, helps minimize manufacturing costs and creates a seamless transition between the design and manufacturing process of the customer's product.

CAD/CAM Design, Solid Modeling, CAM programming, drafting, and file conversion. We provide a full complement of design services to help facilitate the development and the manufacture of your product. Our design and programming tools include:


  • SolidWorks
  • TekSoft CAD/CAM
  • Sigmanest
  • MasterCam

We offer customers complete CAD & CAM flexibility by utilizing quality people and high-end software. Through ongoing training of personnel and frequent software upgrades we provide you seamless integration of your designs into our manufacturing processes.

Our CAD department can work with you to model, draw and verify your part design and our CAM department will evaluate the most efficient method to manufacture it. The CAM department will help choose optimum material size, equipment and process flow to use. Once these have been decided they create the machine code to run your part. The programs are downloaded directly to our CNC machines on the production floor and your part is as good as done.

Our integrated, precision-oriented process guarantees your part meets all your requirements as designed, from idea to final product.

One method for 2D prints, such as .dwg or .dxf files is to create an Adobe® .pdf file from the native file. PDF files seem to scale and print very well, they are easy to email and we’ve found most customers have a PDF reader. But, if you don’t have a PDF writer, we have the capabilities to read in most 2D file types in their native format.

Our programming department does most of our “in house tooling” and fixturing, this allows American Metal Specialties to reduce run times while increasing accuracy and quality. This practice is utilized throughout our manufacturing process, from modified punch, and press brake tooling, to custom hardware installation jigs.

American Metal Specialties also designs welding fixtures to allow larger production runs to be process welded accurately and efficiently. To support our quality control process we can create “Go/No-Go” test fixtures that quickly determine the accuracy of a part at a specific stage of production. These practices translate directly into savings in both time and material.
