Process of Milling

 Milling Processes:

1. Plain/Slab Milling
2. Face/End milling
3. Slot milling/slotting
4. Slitting
5. Angular milling
6. Straddle milling
7. Gang milling
8. Gear tooth milling
9. Sprocket milling
10. Spline milling
11. Groove milling
12. Corner rounding
13. Key seat milling
14. Spiral milling
15. Thread milling

Plain Milling:

 The plain milling is that the commonest sorts of miller operations. Plain milling is performed to produce a plain, flat, horizontal surface parallel to the axis of rotation of a plain milling cutter. The operation is also known as slab milling. To perform the operation, the work and therefore the cutter are secured properly on the machine. The depth of cut is set by rotating the vertical feed screw of the table. And the machine is started after selecting the right speed and feed.

Face Milling:

The face milling is that the simplest miller operations. This operation is performed by a face milling cutter rotated about an axis perpendicular to the work surface. The operation is carried in plain milling, and therefore the cutter is mounted on a stub arbor to style a flat surface. The depth of cut is adjusted by rotating the crossfeed screw of the table.

Side Milling:

The side milling is the operation of producing a flat vertical surface on the side of a workpiece by using a side milling cutter. The depth of cut is set by rotating the vertical feed screw of the table.

Definition and Parts of a Vernier Caliper

Vernier Caliper and Its Parts:   Vernier Caliper Vernier Caliper: The vernier caliper is a measuring tool wont to get precise linear dimension measurements. A vernier micrometer is particularly useful to live the diameter of cylindrical objects as its jaws can clamp either side to urge accurate measurements. Main Parts of a Vernier caliper:   1. Upper Jaws or Inside Jaws   2. Lower Jaws or Outside Jaws 3. Depth Rod   4. Main Scale 5. Vernier Scale 6. Lock Screw 7. Thumb Screw 1. Upper Jaws or Inside Jaws: The upper jaws are smaller in size and are attached to the upper portion of the vernier micrometer. Similar to the lower jaws, one of these jaws is fixed and the other is movable. The difference between them and the lower jaws is that the upper jaws are used for measuring inside dimensions of hollow objects such as inside diameters of pipes, lengths and widths of boxes etc. The jaws are placed inside the place to be measur...

Micrometer and it's main parts

Micrometer and It's Parts:  Micrometer   Micrometer: The micrometer may be a precision measuring system, employed by engineers. Each revolution of the rachet moves the spindle face 0.5mm towards the anvil face. The object to be measured is placed between the anvil face and the spindle face. The rachet is turned clockwise until the thing is ‘trapped’ between these two surfaces and therefore the rachet makes a ‘clicking’ noise. This means that the rachet can't be tightened anymore and therefore the measurement are often read.   Main Parts of Micrometer: 1.      Main Frame 2.      Zero adjusts screw 3.      Anvil 4.      Spindle 5.      Anvil Face and Spindle Face 6.      Lock Nut 7.      Sleeve 8.      Thimble 9.      Rachet 1.      Mai...

Milling Machine

Milling Machine: Milling machine is one of the best machines in Mechanical World. Milling is that the process of removing metal by feeding the work past a rotating multipoint cutter. In milling operation the speed of metal removal is rapid because the cutter rotates at a high speed and has many cutting edges. Thus the jobs are machined at a faster rate than with single point tools and the surface finish is also better due to multi-cutting edges. Milling machine is one among the foremost important machine tools in a tool room as nearly all the operations are often performed thereon with high accuracy. The indexing head makes the machine suitable for therefore many purposes as exact rotation of job is feasible by its use. Milling machine augments the work of a lathe and may produce the plain and curved surfaces and also helical grooves etc. The miller could also be so arranged that the several cutters are mounted on the arbor at an equivalent time, thus increasing the metal rem...
