rolling on another surface. Gear teeth generation by hobbing or gear shaping is the example as can be seen in Fig. 2.6. Fig. 2.5 typically shows the tool-work motions and the corresponding Generatrix (G) and Directrix (D) while producing flat surface by a plain or slab milling cutter in a conventional horizontal arbour type milling machine. The G

This attachment is desirable on horizontal milling machines for substituting the horizontal spindle by a vertical spindle motion. The attachment is a right-angle gear box having bevel gear set in ratio of 1 : 1 and the axis of the vertical spindle could also be swivelled by 45°, thus allowing the machining of bevels and slanted surfaces.

The Milling Machine uses a rotating milling cutter to produce machined surfaces by progressively removing material from a work piece. The vertical milling machine also can function like a drill press because the spindle is perpendicular to the table and can be lowered into the work piece.

Milling machines are very versatile. They are usually used to machine flat surfaces on square or rectangular parts, but can also produce many unique and irregular surfaces. They can also be used to drill, bore, produce slots, pockets and many other shapes. The type of milling machine in the UCR Mechanical Engineering Machine Shop is a variable ...

This is an example of making a spur gear. It is done step by step. The gear to be made has 35 teeth. The size of the teeth is 1 MOD. For a 1 mod gear the pitch circle diameter, pcd is the number of teeth in mm. The outside diameter, od is: OD = pcd + mod * 2. = 37mm. for this example the gear is made of steel 1/4 inch thick.

The vertical milling machine is a precision tool used for shaping and fabrication by the removal of stock typically from metallic work pieces. Plastics and other materials can also be machined on the mill depending upon tooling and material. Mill controls may be manually operated, computer numerical controlled (CNC), or a combination of both.
