2. Laser cutting - Wikipedia

   en.wikipedia.org/wiki/Laser_cutting

   For sheet metal cutting, the focal length is usually 1.5–3 inches (38–76 mm). [7] [8] Advantages of laser cutting over mechanical cutting include easier work holding and reduced contamination of workpiece (since there is no cutting edge which can become contaminated by the material or contaminate the material). Precision may be better since ...

   Some jobs, despite being classifiable as semiskilled work, actually require quite a bit of talent and experience to be done well, for example, band saw operators or buffing and polishing workers. Rigger, a person specializing in the skills needed to move large, heavy objects

   For example, heat may damage the quality of heat treated alloys, and laser cutting is less suitable for highly reflective materials such as aluminum. [2] Laser cutting sheet metal produces flat parts and etches and engraves parts from complex or simple designs. It is used over other cutting options for its quick process and customizable ...

5. Laminated object manufacturing - Wikipedia

   en.wikipedia.org/wiki/Laminated_object_manufacturing

   Laminated object manufacturing (LOM) is a rapid prototyping system developed by Helisys Inc. (Cubic Technologies is now the successor organization of Helisys) In it, layers of adhesive-coated paper, plastic, or metal laminates are successively glued together and cut to shape with a knife or laser cutter. Objects printed with this technique may ...

6. Metalworking - Wikipedia

   en.wikipedia.org/wiki/Metalworking

   Metalworking generally is divided into three categories: forming, cutting, and joining. Most metal cutting is done by high speed steel tools or carbide tools. [7] Each of these categories contains various processes. Prior to most operations, the metal must be marked out and/or measured, depending on the desired finished product.

   For cut path, most machines give the options of tracing the vectors, cutting outside the vectors, or cutting inside the vectors. The operator determines the center point of the part, clamps the part onto the table, moves the bit directly above the marked center and down to the face of the part, and marks this as the starting point.
