| In the Middle Ages, falconry was a very popular pastime (what today might be called a hobby), and of all the different birds used for it, the Eurasian Hobby was perhaps the most popular. It is said that the modern use of hobby to indicate a pastime followed from this. An alternative explanation is that the usage grew from another recreational animal called hobby: which was a type of small ambling or pacing horse. A hobby-horse was a wooden or wickerwork toy made to be ridden just like the real hobby. From this came the expression "to ride one's hobby-horse", meaning "to follow a favourite pastime", and in turn, hobby in the modern sense of recreation. Hobbies are practised for interest and enjoyment, rather than financial reward. Examples include collecting, creative and artistic pursuits, making, tinkering, sports and adult education. Engaging in a hobby can lead to acquiring substantial skill, knowledge, and experience. However, personal fulfillment is the aim. What are hobbies for some people are professions for others: a game tester may enjoy cooking as a hobby, while a professional chef might enjoy playing (and helping to debug) computer games. Generally speaking, the person who does something for fun, not remuneration, is called an amateur (or hobbyist), as distinct from a professional.

2) "Cnc" -- As to hobby cnc CNC
Function: abbreviation
computer numerical control Pronunciation Symbols
A CNC Turning Center A CNC Milling Machine The abbreviation CNC stands for computer numerical control, and refers specifically to a computer "controller" that reads G-code instructions and drives the machine tool, a powered mechanical device typically used to fabricate metal components by the selective removal of metal. CNC does numerically directed interpolation of a cutting tool in the work envelope of a machine. CNC was developed in the late 1940s and early 1950s by John T. Parsons in collaboration with the MIT Servomechanisms Laboratory. CNC was preceded by NC (Numerically Controlled) machines, which were hard wired to produce one specific part. The first CNC systems used NC style hardware, and the computer was used for the tool compensation calculations and sometimes for editing. Punched tape continued to be used as a medium for transferring G-codes into the controller for many decades after 1950, until it was eventually superseded by RS232 cables, floppy disks, and finally standard computer network cables. The files containing the G-codes to be interpreted by the controller are usually saved under the .NC extension. Most shops have their own saving format that matches their ISO certification requirements. The introduction of CNC machines radically changed the manufacturing industry. Curves are as easy to cut as straight lines, complex 3-D structures are relatively easy to produce, and the number of machining steps that required human action have been dramatically reduced. With the increased automation of manufacturing processes with CNC machining, considerable improvements in consistency and quality have been achieved. CNC automation reduced the frequency of errors and provided CNC operators with time to perform additional tasks. CNC automation also allows for more flexibility in the way parts are held in the manufacturing process and the time required to change the ma..."
