1. MILLING By: Jacob Eames

2. setup The time required to produce a given quantity of parts includes the initial setup time and the cycle time for each part. The setup time is composed of the time to setup the milling machine, plan the tool movements and install the fixture device into the milling machine. The cycle time can be divided into the following four times:

3. Load/Unload time - The time required to load the work piece into the milling machine and secure it to the fixture. Cut time - The time required for the cutter to make all the necessary cuts in the work piece for each operation.

4. Idle time - Also referred to as non- productive time, this is the time required for any tasks that occur during the process cycle that do not engage the work piece. Tool replacement time - The time required to replace a tool that has exceeded its lifetime and therefore become to worn to cut effectively.

5. Processes there is no post processing that is required. However, secondary processes may be used to improve the surface finish of the part if it is required.

6. Machines Milling machines can be found in a variety of sizes and designs, yet they still possess the same main components that enable the work piece to be moved in three directions relative to the tool.

7. Stock the raw form of the material is called stock from which the work pieces cut from. This stock is available in a variety of shapes such as flat sheets, solid bars, hollow tubes, and shaped beams, and Custom extrusions or existing parts such as castings or forgings are also sometimes used.

8. Milling can be performed on work pieces in variety of materials, including most metals and plastics. Common materials that are used in milling include the following: Aluminum, Brass, Magnesium, Nickel, Steel, plastic, Titanium, Zinc.
