Punch presses are generally used when a CNC mill would be inefficient or unfeasible. CNC punch presses can come in the C frame, where the sheet material is clamped onto a machining table and a hydraulic ram pushes down on the material, or they can come in a portal frame variant where bar stock/tubing is fed into the machine.

Manufacturing complexity The manufacturing environment is increasingly complex. The need for CAM and PLM tools by the manufacturing engineer, NC programmer or machinist is similar to the need for computer assistance by the pilot of modern aircraft systems. The modern machinery cannot be properly used without this assistance.
[1] In the manufacturing industry, with regard to numerically controlled machine tools, the phrase machine coordinate system refers to the physical limits of the motion of the machine in each of its axes, and to the numerical coordinate which is assigned (by the machine tool builder) to each of these limits. CNC Machinery refers to machines and devices that are controlled by using programmed ...
The idea of "digital manufacturing" became prominent in the early 1970s, with the release of Dr. Joseph Harrington's book, Computer Integrated Manufacturing. [5] However, it was not until 1984 when computer-integrated manufacturing began to be developed and promoted by machine tool manufacturers and the Computer and Automated Systems Association and Society of Manufacturing Engineers (CASA/SME).
Generally, four types of graphic illustrations are used: 2D drawings, for example, in DXF format according to the ISG/BMG standard for geometrical information; PDF data of the tool manufacturer as a data sheet with exploded view; 3D data (e.g. STEP or STL) for the use in CAM systems; Photos (e.g. JPG) as graphical information
Reconfigurable Manufacturing System Architecture by Y. Koren. The system is composed of stages: 10, 20, 30, etc. Each stage consists of identical machines, such as CNC milling machines. The system produces one product. The manufactured product moves on the horizontal conveyor. Then Gantry-10 grips the product and brings it to one of CNC-10.
As with CNC milling machines, CNC routers can be controlled directly by manual programming, but CAD/CAM allows wider possibilities for contouring, speeding up the programming process and in some cases creating programs whose manual programming would be impractical. On some controllers the G-code can be loaded as a vector file on the router ...
CNC machines are classified according to the number of axes that they possess, with 3, 4 and 5 axis machines all being common, and industrial robots being described with having as many as 9 axes. CNC machines are specifically successful in milling materials such as plywood , plastics , foam board , and metal at a fast speed.
