Types of Process
Wire (EDM)
A process of a drawing wire slowly on the surafce of the workpiece with a predetermined path. The system consist of a dielectric fluid between the wire and the workpiece acting as a plasmic channel in the gap developing million sparks per second. This Process allows to cut the workpiece with high thickness and construct most complicated structure preciously.
Sinker (EDM)
Consist of workpiece and a electrode tool connected to a power supply which acts as anode and cathode in the system respectively. Dielectric fluid in the system act as ionizing channel which generates sparks as the apower supply is passed through in the operating system.
A method of removing a part of the materials by conducting a a series of sub sequently occuring discharge (spark) on the workpiece. This process requires two electrodes seperated by a dielectric liquid which consist of intense electric fields.

Types of milling processes
Face Milling
Types of face milling
Surface countering
Consist of a cutting tool with a curved edge, which follows a curved path on the milling surface constructing a contour on the workpiece.
Conventional Face milling
A process of milling consist of rotational axis of milling cutter perpendicular to the milling surface.
Peripheral Milling
Types of Peripheral milling
Slotting
Consist of a milling cutter with a width smaller than the periphery of the workpiece. Allows to create a slots on the workpiece.
End milling
Types of end milling
Profile milling
Consist of rotating tool cutting on the periphery of the workpiece.
Pocket milling
Consist of a cutting tool creating a shallow feature with certain depth.
Consist of a cutting tool held vertically to the milling surface with its diameter less than the width of workpiece causing a slot in the part
Slab milling
Consist of a milling cutter with a width larger than the periphery of the workpiece. Allows to create a planar surface on the workpiece.
A method which consist of axis of rotation of a milling cutter parallele to the workpiece feed. The proximity of the milling cutter teeth are at the periphery of the milling surface.
A cutting process which consist of a milling cutter with mulitiple cutting edges held perpendincular to the direction of the workpiece fedding, which allows us to develop a planar surface, slots, grooves, and certain dimensional profiles

Radially holding a cutting tool to cut out the a part of the rotating workpiece
Facing
A method of rotating a metal part with a cutting tool held perpendicular to the rotational axis of the workpiece.
Threading
Consist of rotating metal part against the Pointed cuttng tool held parallel to the rotational axis causing threads in the work piece.
Chamfering
Consist of a Metal part rotated aginst a cuting tool with a sharp edge, cutting the surface at an angle causing a formation of a chamfer.

Types of torches
Cutting torch
Allows us to cut several materials. It consist of three pipes containg gaseoues fuels and an oxygen trigger which is used to cut materials.Element is preheated so as oxygen blast trigger is conducted, oxygen react with themetal forming metal oxides, reducing its strength and thereby cutting the worpiece.
Injector torch
Consist of an oxygen flow with two gaseous fuels through the venturi effect along which allows to maintain an equilibriium between the amount of oxygen and gaseous fuels in the flow.
