The application of CNC comprises both for Non-machine tool and Machine tool fields.
Machine tool Group:-
In this group the CNC is widely used for Milling machine, lathe machine, drill press, laser, sheet-metal press working machine etc.
Non-Machine tool group:-
In this group the CNC applications includes welding machines (Arc & resistance), electronic assembly, tape laying and filament winding machines for composites etc.
ADVANTAGES AND LIMITATIONS OF CNC
Some advantages of CNC are:
• Time required for production is less.
• Accuracy is high.
• Manufacturing flexibility is greater.
• Contour machining (2 to 5 –axis machining)
• Reduction in human errors etc.
Some Drawbacks of CNC
• High equipment cost.
• Maintenance cost is high.
• Skilled programmer is required for operating CNC. Etc.
CNC milling machine is the most commonly used machine which is based on computer numerical control. Different types of milling machines and parts of CNC machine is discussed below.
MILLING MACHINE
Milling machine is a machine which is used to perform various operations like cutting and shaping of solid materials. Milling is most common process nowadays used in industries and in workshops for machining of different materials to precise sizes and shapes.
A milling machine can be a Horizontal or Vertical which depends over the orientation of the spindle. In the milling machines the movement of work-piece and the milling cutter can be controlled manually and cutting fluid

As Document A states, these machines were crucial because they put less strain on the human body. Too much manual labor on a day to day basis can lead to severe mental exhaustion. Mechanized factories helped alleviate that issue to a high degree. New agricultural technology such as the Jethro Tull Horse Drawn Seed Drill, which made farming more efficient because it was able to plant, cover and harvest crops simultaneously. Since farming was now more accessible, the price of crops went down due to higher supply with the same demand.

One of the disadvantages was wasted resources. If there was anything with the product design, or the assembly line, that meant every item in the entire production cycle was effected. When this happened, the manufacturer would often have to get rid of all f these items, attempt to fix the issue, and start over. This led to a lot of wasted product, which was an even bigger problem when resources were limited to begin with. Alon with concern of wasted resources due to manufacturing discrepencies, there was no assurance that the products would sell even if they were all made correctly.

Next, they calculate where to cut or bore into the workpiece—the piece of steel, aluminum, titanium, plastic, silicon, or any other material that is being shaped. They determine how fast to feed the workpiece into the machine and how much material to remove. They then select tools and materials for the job, plan the sequence of cutting and finishing operations, and mark the workpiece to show where cuts should be made. These are steps of how that begin to a project so when being an apprentice these are the types of things you will do as
