Non conventional Machining is a recent development in machining techniques. It is based on unconventional machining techniques using Laser beam, Electron beam, Electric arc etc. Conventional machining involves the direct contact of tool and work -piece, whereas unconventional machining does not require the direct contact of tool and wor piece. Conventional machining has many disadvantages like tool wear which are not present in Non-conventional machining.
Examples : Electric arc machining, Laser cutting , electro discharge machining, plasma cutting etc
Advantages of Non-conventional machining:
1) High accuracy and surface finish
2) no direct contact of tool and workpiece, so there is less/no wear
3) tool life is more
4 ) quieter operation
Disadvantages of non-conventional machining:
1) high cost
2) complex set-up
3) skilled operator required
in conventional machines force is directly applied from tool to the work piece in non-conventional machines we don't apply the force directly from tool to the work piece. here we use different forms of energy which we applied in order to get desired profile like thermal energy, chemical energy etc. here tool need not to be harder than the work piece.
There are many differences between conventional machining and non-conventional machining. One difference is that conventional machining uses motion, a mechanical energy and non-conventional machining uses thermal, chemical or electrical energy.

The non traditional machining can machine high hardness materials compared with traditional. Also in non traditional, the machining tool and work piece are not connecting together.
CNC milling machine is controlled by computer, but is controlled by a conventional milling machine operator.
non-conventional machining process means non-traditional or non-standard machining process
how do you specify a milling machine
A person who operates a milling machine is called a milling machine operator, milling machinist or a machinist.
how to calculate forces on coulmn of horizontal milling machine?
Horizontal and vertical milling machine.
Milling in a lathe can be two things:A cutter is gripped in the chuck and a workpiece the the tool post. The work piece is then milled by using the feed on the lathe. Although it has been done, it is an unconventional method and is not recommended.A 3-in-1 lathe with a milling attachment as part of the machine used for milling a work piece.
You may be looking for the difference between Climb vs Conventional milling. Also known as Down milling and Up milling respectively. In short, the difference is the direction that the teeth of the cutting tool move relative to the material. This can primarily affect smoothness of resulting cut, tool life, and the force on the machine and material. Better description can be found in these links: http://en.wikipedia.org/wiki/Milling_cutter#Conventional_milling_versus_climb_milling http://clinetoolmexico.com/pdf/fresado_tecnica.pdf
The main defference is in Milling Machine job is fixed and tool will move. For planning machine tool is fixed and bed will reciprocate.
A milling machine is used to transform pieces of metal into multiple geometric shapes.
Horizontal and vertical milling machine.

the milling machine was invented in 1818.
Vertical milling machine and horizontal milling comparison, the main difference is the spindle vertical layout, except for different spindle arrangement, table can move up and down, vertical milling cutter with relatively flexible, wider scope. Use cutter, cutter support, drill and so on. Can keyway milling, milling flat and boring.
Basic difference between turning and milling is that , In turning the tool is fixed and the job rotates whereas in milling the job is fixed and the tool rotates
Upmilling and down milling are also known as conventional milling & climb milling. the process in which the cutting tool cuts the material and forms a chip which is big in the starting and thin in the end is known as climb or down milling. The figure is self explanatory. Upmilling or Conventional milling
