Electrical discharge machining is a quick and unique way to create accurate deep small holes drilling in materials, regardless of their hardness. The hole drilling process involves using a brass electrode tube to channel the electrical discharges onto the material. This helps to create holes of various small dimensions.
The process of milling wheat is what transforms this important grain into flour so that it can be used to make a variety of foods. Once the wheat has been harvested, the milling process begins with inspection and cleaning. Then the wheat is conditioned so that the parts of each kernel separate more easily, and the grinding process begins.

Milling Machine Definition: The milling machine is a type of machine which removes the material from the workpiece by feeding the work past a rotating multipoint cutter.The metal removal rate is higher very high as the cutter has a high speed and many cutting edges. It is the most important machine in the tool room as nearly all the operations can be performed on it with high accuracy.
G-code is the operational language for CNC machining. It tells numerically controlled lathes and machining centers how to move tools in order to perform various cutting operations. It is equivalent to manual programming where each operation is spelled out line-by-line and is separate from M-code and T-code, codes that control the machine and tooling.
• A milling machine removes metal by rotating a multi-toothed cutter that is fed into the moving workpiece. The spindle can be fed up and down with a quill feed lever on the head. • The bed can also by fed in the x, y, and z axes manually.
Aluminum oxide grinding wheel is commonly used in making the grinding wheel and will be best suited for grinding the ferrous metals having high tensile strength e.g. hard steel, wrought iron etc. ; Silicon carbide grinding wheel is used to grind the softer, low tensile strength, high density and non-ferrous materials such as brass, aluminum and softer bronze.

Basic- all things being equal, this is the amount of material your tool encounters in percentage of the tool diameter. The lower the percentage the lower the force on the machine, the more accurate the cut. Expanded-A good thing to know is most flutes are not 50% of the diameter of the bit, usually less.
What is the principle of milling process? In this machine, the metal is cut employing a rotating cutter having multiple cutting edges. For cutting operations, the workpiece is fed against the rotary cutter. As the workpiece moves against the cutting edges of the milling cutter, metal is removed in the form of chips.
