Study Notes
Machining Operations
- The major diameter, pitch diameter, and core diameter are essential parameters in machining operations.
Roller Box Turning Tool Holder
- The rollers used in the roller box turning tool holder are convex shaped.
Face Plate
- During machining operation using a face plate, the angle plate is held on the tailstock.
Centre Drill
- The size of the centre drill is determined on the basis of the diameter of the workpiece.
Milling Operations
- Plain milling is done for machining flat surfaces.
- Stub arbor type 'a' is used for mounting a shell end mill.
Milling Cutter
- The round portion of the chip space on a milling cutter is called the fillet.
Rotary Table
- Rotary table is used on a milling machine to achieve a combination of longitudinal and cross movement.
Units
- Radian is a unit of angle.
Plug Gauge
- Plug gauge is used for checking hole dimensions.
Shrink Rule
- The centimeter of a shrink rule is smaller than the actual centimeter.
Dial Test Indicator
- There are three types of dial test indicator stands.
Interchangeability
- The difference between high limit size and low limit size is called tolerance.
