   The code proved to have a serious problem; the printers would sometimes smear ink, rendering the code unreadable in most orientations. However, a linear code, like the one being developed by Woodland at IBM, was printed in the direction of the stripes, so extra ink would simply make the code "taller" while remaining readable.

3. CNC router - Wikipedia

   en.wikipedia.org/wiki/CNC_router

   CNC router. A computer numerical control ( CNC) router is a computer-controlled cutting machine which typically mounts a hand-held router as a spindle which is used for cutting various materials, such as wood, composites, metals, plastics, glass, and foams. CNC routers can perform the tasks of many carpentry shop machines such as the panel saw ...

4. Numerical control - Wikipedia

   en.wikipedia.org/wiki/Numerical_control

   A CNC metal lathe with the door open. In machining, numerical control, also called computer numerical control ( CNC ), [ 1] is the automated control of tools by means of a computer. It is used to operate tools such as drills, lathes, mills, grinders, routers and 3D printers. CNC transforms a piece of material ( metal, plastic, wood, ceramic ...

5. G-code - Wikipedia

   en.wikipedia.org/wiki/G-code

   G-code (also RS-274) is the most widely used computer numerical control (CNC) and 3D printing programming language. It is used mainly in computer-aided manufacturing to control automated machine tools, as well as for 3D-printer slicer applications. The G stands for geometry. G-code has many variants. G-code instructions are provided to a ...

6. Milling (machining) - Wikipedia

   en.wikipedia.org/wiki/Milling_(machining)

   Milling is the process of machining using rotary cutters to remove material [ 1] by advancing a cutter into a workpiece. This may be done by varying directions [ 2] on one or several axes, cutter head speed, and pressure. [ 3] Milling covers a wide variety of different operations and machines, on scales from small individual parts to large ...

7. PCB NC formats - Wikipedia

   en.wikipedia.org/wiki/PCB_NC_formats

   PCB NC drill files convey PCB drilling and routing information. The NC formats were originally designed by CNC drill and route machine vendors as proprietary input formats for their equipment, and are known under their company name: Excellon, Hitachi, Sieb & Meyer, Posalux, etc. These formats are similar as they are based on RS-274-C and ...

8. History of numerical control - Wikipedia

   en.wikipedia.org/wiki/History_of_numerical_control

   The history of numerical control (NC) began when the automation of machine tools first incorporated concepts of abstractly programmable logic, and it continues today with the ongoing evolution of computer numerical control (CNC) technology. The first NC machines were built in the 1940s and 1950s, based on existing tools that were modified with ...

9. CNC wood router - Wikipedia

   en.wikipedia.org/wiki/CNC_wood_router

   A CNC wood router is a CNC router tool that creates objects from wood. CNC stands for computer numerical control. The CNC works on the Cartesian coordinate system (X, Y, Z) for 3D motion control. Parts of a project can be designed in the computer with a CAD/CAM program, and then cut automatically using a router or other cutters to produce a ...
