Which one of the following statements related to grinding process is ...
Explanation:
The incorrect statement related to the grinding process is option 'D', which states that cutting speed in the grinding process is much lower than that in face milling.
Understanding Grinding Process:
Grinding is a material removal process that uses a grinding wheel as a cutting tool to remove material from a workpiece. It is a complex process that involves various parameters and factors to achieve the desired results.
Key Points:
1. Finer Abrasive Grains for Better Surface Finish: Grinding wheels made of finer abrasive grains produce better surface finish. Finer grains result in smaller chip size, which leads to a smoother surface finish. Therefore, statement 'a' is correct.
2. Fracture of Abrasive Grains: During the grinding process, abrasive grains tend to fracture frequently. This is because the grains are subjected to high forces and stresses, leading to their breakage. Fracturing of grains helps in maintaining sharp cutting edges and prevents the formation of a dull and ineffective grinding wheel. Therefore, statement 'b' is correct.
3. Specific Energy in Grinding: Specific energy is defined as the amount of energy required to remove a unit volume of material during the grinding process. It is measured in terms of energy per unit volume (J/mm³) or energy per unit width of cut (J/mm). Specific energy in grinding is generally higher than that in turning due to the higher forces involved and the generation of heat. Therefore, statement 'c' is correct.
4. Cutting Speed in Grinding: In the grinding process, the cutting speed is typically much lower than that in face milling. This is because grinding is a precision process that requires careful control of the cutting forces and heat generation. Higher cutting speeds can lead to excessive heat, which can cause thermal damage to the workpiece. Therefore, statement 'd' is incorrect.
Conclusion:
The incorrect statement related to the grinding process is option 'D', which states that cutting speed in the grinding process is much lower than that in face milling. In reality, the cutting speed in grinding is typically lower than that in face milling to ensure precision and avoid thermal damage.

Which one of the following statements related to grinding process is ...
Grinding wheels are made of very fine abrasive grain. Finer will be the abrasive grain better will be the surface finish. During grinding, abrasive grains which is made of brittle material tend to fracture frequently.
Specific energy of grinding 50 J/mm3
Specific energy of turning 2 J/mm3 to 5 J/mm3
Cutting speed in grinding is much higher than that in face milling.
