Distinguish betweenconventionaland unconventional Manufacturing process used in Industries

There is no hard and fast answer to this question. Some thread mills are far faster than standard machine taps, some high-performance machine taps are faster than thread mills. It depends entirely on the application and the tools being used. However, thread mills are far safer to use than taps and can prevent scrapping of workpieces due to broken tools.

There are plenty of differences between conventional machining and non-conventional machining processes. Here is a complete list of these differences:

Electro chemical machining combines the chemical machining process with electrical energy. This process is the opposite of electroplating. This process is independent of surface hardness and machinability. Therefore, it can be used to machine hard materials with ease. It is also good for machining materials with poor machinability. Applications for ECM are:

Reaming is used to enhance the quality and precision of holes. Reaming operations are used for the secondary finishing of workpiece holes. It can make the hole diameter more accurate, round, and with a smooth surface finish. Reaming utilizes multi-point cutting tools. Reaming machine is called a reamer. The reaming process follows holes created by drilling or boring. Applications of reaming are:

Non conventional machining process does not use traditional cutting tools. Instead, these machining techniques utilize heat or force for material erosion. Non conventional machining processes are more modern with high precision. Let us go through these various types of machining operations:

Indexable thread mills are generally for larger diameter threads, however there is a cross over between solid and indexable thread mills at around M16. Solid carbide thread mills will offer greater rigidity (indexable tools and mainly HSS shanks), often have longer flute lengths and more flutes, so they can be faster than most indexable thread mills. However, they can also be very expensive compared to indexable thread mill inserts above M16. Indexable thread mills offer the flexibility of being able to machine different thread forms and pitches with one holder. This makes them a very cost-effective solution. They are also exceptionally cost effective for large diameter threads. Some indexable thread mills are available with multiple inserts for higher performance applications, or with very long holders for long reach applications. In summary, it depends entirely on the tools being used and the application.

Conventional machining operations rely on metal alloy cutting tools. Commonly used cutting tools are made of carbide steel or high-speed steel. However, non-conventional machining operations rely on other means. For instance, cutting action in these techniques can be achieved by water force, electrical heat, chemical reactions, or friction of abrasive particles.

The non-conventional machining process is generally far more accurate than conventional alternatives. In non-conventional machine operation, the thickness of the cutting medium can be narrowed down to extreme proportions. For instance, the laser beam or electrical arc is smaller than the thickness of a human hair. This leads to extremely precise cuts with little kerf width.

Tapping cutting tool is used to make internal threads on the work material. The cutting tool itself is called the tap. Tap can have a cylindrical or conical shape. The tap rotates and moves inside the workpiece linearly. This results in the thread formation on the internal periphery of the workpiece. Holes are pre-drilled on the workpiece with drilling or boring. Application of tapping are:

Thread mills are a high precision tool yet most customers use them in ER collet chucks and without through coolant. By using a hydraulic chuck, shrink chuck or any other holder with <0.003mm run-out, you will reduce vibration and therefor tool life and thread quality. Secondly, by using a through coolant thread mill it clears the chips out of the hole and prevents ‘double cutting of the swarf’ which can damage or mark the threads.

Machining is a manufacturing process that removes material in a controlled manner to produce the required part. Therefore, machining is also known as a subtractive manufacturing process. The workpiece is always bigger than the required part. Machining processes have a higher precision than alternatives like additive manufacturing techniques.

Shaping machine is a fast way of altering the basic shape of a workpiece. It uses the reciprocating mechanism between the cutting tool and the workpiece. The workpiece moves back and forth against the cutting tool. Shaping can generate flat surfaces, inclines, and even curved surfaces. Applications of shaping are:

The material removal rate in conventional machining operations is higher. This is because of a higher tool contact with the workpiece. It also leads to faster tool wear. In non-conventional processes, the material removal rate is slower.

A conventional machining process has limited accuracy. This is because of the limitations on the minimum thickness of the cutting tool. However, non-conventional machining processes are highly precise. This is because the thickness of laser, water, or electrical arcs can be narrowed down to a microscopic level.
