2. Model engineering - Wikipedia

   en.wikipedia.org/wiki/Model_engineering

   Increasingly, 'modern' technologies such as Computer aided design, cnc (computer numerical control) equipment, laser cutting, 3D printing and embedded systems are becoming part of the hobby as more and more of its practitioners have developed skills and familiarity with these techniques through their work, whilst younger people familiar with ...

3. Milling (machining) - Wikipedia

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

   The original class of machine tools for milling was the milling machine (often called a mill). After the advent of computer numerical control (CNC) in the 1960s, milling machines evolved into machining centers : milling machines augmented by automatic tool changers, tool magazines or carousels, CNC capability, coolant systems, and enclosures.

4. Digital modeling and fabrication - Wikipedia

   en.wikipedia.org/wiki/Digital_modeling_and...

   CNC mills or routers include proprietary software which interprets 2D vector drawings or 3D models and converts this information to a G-code, which represents specific CNC functions in an alphanumeric format, which the CNC mill can interpret. The G-codes drive a machine tool, a powered mechanical device typically used to fabricate components. [4]

5. Hobby injection molding - Wikipedia

   en.wikipedia.org/wiki/Hobby_injection_molding

   Benchtop injectors have become more common as inexpensive CNC milling machines have reduced the cost of producing molds in a home workshop. In hobby injectors injection pressure is generated manually by the operator, with a lever [1] [2] [3] or gear [4] [5] translating the operator's effort to the required pressure. The most common hobby ...

6. Multiaxis machining - Wikipedia

   en.wikipedia.org/wiki/Multiaxis_machining

   CAM software automates the process of converting 3D models into tool paths, the route the multiaxis machine takes to mill a part (Fig. 1). This software takes into account the different parameters of the tool head (in the case of a CNC router, this would be the bit size), dimensions of the blank, and any constraints the machine may have.

7. Machine tool - Wikipedia

   en.wikipedia.org/wiki/Machine_tool

   Eli Whitney milling machine, c. 1818. Important early machine tools included the slide rest lathe, screw-cutting lathe, turret lathe, milling machine, pattern tracing lathe, shaper, and metal planer, which were all in use before 1840. [12] With these machine tools the decades-old objective of producing interchangeable parts was finally realized ...
