Article 1

__summary__ This article disscussion about the advantage and disadvantage of cnc milling machine.Nowadays, this machine are widely in manufacturing indusdry and everybody can use this machine but they should know how to handle this machine. Then we can compare between advantange and disadvantage cnc milling machine in this article. For example, this machine can be use continuously 24 hours a day, 365 days a year. And disadvantage for this machine are more expensive than manually operated machines.

Article 2

__summary__

For this article, also discuss about the advantage and specifications for CNC Milling. For advantage, complex shapes from sheet material can be created and is cost so effective for short runs. For specification cnc milling machine requires software program tooling or work holding jigs and also to contain costs avoid large variations in work piece height and avoid

Article 3

__summary__ This article disscussion about the advantage over the order horizontal milling machine design. The advantage are brigdeport type milling machine usually 1 - 5 horsepower motor. Beside that, the horizontal milling machine must use bigger cutting tool vertical mills. then vertical milling machine are less complex than horizontal milling machine.

article 1 __Article Summary__ Conventional milling machine is a material-working processes that used with a sharp cutting tool to mechanically cut the material in order to achieve the desired geometry. Computer Numerical Control (CNC) Milling can perform the functions of drilling and turning. The number of CNC axis are labeled as x and y for horizontal movement, and z for vertical movement: A five-axis CNC milling machine has an extra axis in horizontal that will allows extra flexibility for machining with providing an angle to create desired geometry that we want. CNC milling machines are programmed using a set of commands known as G-codes. The G-codes are programmed in alphanumeric format that will be represent specific CNC functions to run the machine in order to cut the workpiece as we want.

Article 2

__Article summary__ In this article, it describe milling as a process of cutting away material of a workpiece using variety rotating tooth cutter. The surface that we cut can be milled to any combination of shapes such as flat, angular, or curved. This article also have the classification, methods, equipments, the types and also the research on milling

Article 3

__Article summary__ In this article,a milling machine is used for the shaping of metal. This machine function due to the orientation of the cutting tool spindle with the existence of horizontal and vertical axis. It use to cut metal that involves the movement of workpiece against the rotating cutter. Milling machines can be manually, mechanically, or digitally operated. This machine can go through various types of operations. It also has cutting fluid to cool the cutting site. The CNC milling machines function by using computer controlled. This machine has five-axis with addition two more axis combined with the three normal axis (XYZ) that programmed with CAM. All of these axis are used in conjunction with each other, so that various geometries can be made with these machines

Article 1

__Article Summary__

=
In production application there need a faster machine to make a lot of product, to improve the productivity milling machine will use to make the product.The main function of this machine is to remove the part from the material that was not use. So to full fill this main function there need the application of these machine to remove the part that not use.The application in this machine is can engrave by using endmill, cut radial and angles without a rotary table, make a pocket and cut ellipses and frames. It also can make a hole by using the drill.=====

Article 2

__Article Summary__ ====In CNC milling technology provide three-axis capability to the mill but manual milling machine the operator/machinist set all the parameter involve in machining process such as change tools, and manually direct all table movement. In milling process the most important application is the milling cutter, this is because cutting radial angles and surface mill will use this cutter.====

Article 3

__Article Summary__ ====CNC milling machine can perform fuction such as drilling and milling, but with the four axis this machine also can make a turning process. In the main application of this machine material is usually removed by both the end and the side of cutting tool. In cutting process the material is removed from a block by a rotating tool.The part features that produce from CNC machine is walls, pockets of different depths, tapped holes and both-hole circle pattern.====
