Which machining process is having highest specific energy consumption?

Abrasive machining
Abrasive machining is characterized by high energy consumption and relatively low mechanical efficiency.

How does grinding differ from other machining process?

Machining is primarily a bulk removal process (high MRR). It can also semi-finish the surfaces. Grinding is primarily a surface finishing process. It gives low MRR.

What is specific energy in grinding?

Specific grinding energy is a parameter that represents the relationship between input and output of the grinding process. By obtaining specific grinding energy of each grinding wheel, the appropriate cutting rate (cutting depth and feed rate) under specific condition can be estimated.

Which process in the machining consumes the maximum specific energy among the conventional machining processes and validate your preference?

Correct Option: D. Grinding because of smaller chips, large cutting area.

What is difference between EDM and ECM?

EDM, or electrical discharge machining, relies on localized spark erosion to remove material, whereas ECM, or electrochemical machining, utilizes electrolysis to dissolve the metal locally.

On what factors does specific energy depend in disc cutting?

The value of specific energy depends particularly on workpiece hardness and wheel sharpness. The high value is typical of a difficult-to-grind material and the low value of an easy-to-grind material.

Whats the difference between grinding and milling?

While they both involve the physical removal of material from a workpiece, milling and grinding aren’t the same. The former machining process is characterized by the use of a milling machine, whereas the latter machining process is characterized by the use of a grinding wheel.

Why is grinding so important in modern production?

As you can see, industrial grinding machines are an important part of industries today because they allow companies to extract minerals, reduce the particulate size of materials, and create nanostructure materials mechanically with high precision and at a low cost.

Why specific energy in grinding is high?

Grinding is a multi-point cutting operation. Such high specific energy required in grinding can be attributed to the irregular and random geometry of the abrasive grits, which induce a lot of rubbing and ploughing actions along with the chip formation by shearing process.

Why are there large difference between the specific energies involved in grinding?

The Material removal rate for grinding is much lesser than that achieved in machining. Rubbing and Ploughing also consumes energy without removing material. Hence, the specific energy requirement of grinding is much higher than that of conventional machining.

Why specific energy in grinding is much higher than in single point cutting?

Abstract. Grinding is a multi-point cutting operation. Such high specific energy required in grinding can be attributed to the irregular and random geometry of the abrasive grits, which induce a lot of rubbing and ploughing actions along with the chip formation by shearing process.

What is the dissimilarity between EDM and ECM?

Both ECM and ECM are non-conventional machining methods; however, that one letter makes a big difference! EDM, or electrical discharge machining, relies on localized spark erosion to remove material, whereas ECM, or electrochemical machining, utilizes electrolysis to dissolve the metal locally.
