Hunger is needed!!!!

This is the entrance exam season in India. You have NEET, JEE, CAT, MAT etc. Students in large number appear in the exams. When I see the results in newspapers, it is evident that students from middle class and poor families are doing great in large numbers. On the other hand, students from well off families doing very poorly. Some of the parents are in very high posts and their children are not able to perform at all. This is not like that there is no guidance from parents, it is the hunger that is lacking in them. The affluence and privileges make people soft. Hunger to be the best is much needed in every field. Once you become complacent with your current situation, you cannot grow more. If you do not grow, you will be trampled by this ruthless world.

India is a poor country or I can say developing country. Our organizations are running at with very low funding. This is not like that the government wants it like this way. We have so many things going on at a same time we cannot focus. It is hard. Then there is geopolitics. One country never allows another to go on the top. It is like human nature. Still, we have to continue. Now, students have to understand that the teachers are overworked; so many administrative, research and academic pressure one cannot imagine. Then, one must know that it is one of the lowest paying jobs since the time immemorial. When have you heard a rich teacher? There was never one and will never one in future you. People choose it for the love of the profession.  It will be like this in coming years also. In our days, though we studied in engineering college, we thought them as teachers and not as engineers. How foolish to think that.  It takes time to build this understanding. Moreover, years of administrative, academic pressure and family pressure, one becomes overwhelmed and keeps on doing as the things come by. There is hardly any energy for any innovative thinking. This is not as gloomy as it seems. There is always some spark left and hunger to do good. Everyone has it. There is something good in every one which is pure and serene. If you can approach a teacher in engineering college, he will try to help. Sometimes, you have to jolt the old tree to get the ripe fruits from it.

Last Mile Push

Many a time in life, we do not get admission in the college what we want. Sometimes there is a lot of disparity and sometimes there is a little bit of difference between what we have desired and what we have.  The college might be a new one trying to make a mark. In such case, one should look for faculty profile. If they are able then there should be no problem. Most people are generally happy to help but we do not want to take help. How many times have we asked for help in a certain problem? Nil, right. You have to be positive and do your job as a student without sulking.

I have seen students complaining of not getting what they desired. We need to keep in mind that the college education will be common to all and a standardized process. No college in the world can give a customized education. Only a private tutor may be able to do so. If you are interested really in a subject, you have to go alone at first in that direction because it is your only interest. Other classmates may have hundreds other goals and won’t stand with you. A student with a degree means that the student has basic knowledge of the certain field and it is a great filter for higher education or job application. If you want job in a certain sector, you have to push yourself to the last mile to attract an employer for picking you up.  Hence, you have to learn the things of their trade on your own by taking extra courses. Your college may not provide you that knowledge but there is internet and above all Chat GPT now a days to teach you those things in a custom way. The only thing you need is the willingness to learn.

10 Common Manufacturing Process Questions Asked in The Interviews: Theory Series 04

Q1 : What is a manufacturing process? A: A manufacturing process is a series of steps and operations involved in converting raw materials or components into finished products on a large scale.

Q2 : What are the different types of manufacturing processes? A: There are several types of manufacturing processes, including:

1. Casting: It involves pouring molten material into a mold to create a desired shape.
2. Machining: This process uses cutting tools to remove material and shape the final product.
3. Forming: It involves deforming or reshaping materials through processes like bending, rolling, or extrusion.
4. Welding: It joins two or more pieces of material by melting and fusing them together.
5. Assembly: It involves putting together different components to create a finished product.
6. 3D Printing: This additive manufacturing process builds three-dimensional objects by layering materials based on a digital design.

Q3 : What is lean manufacturing? A: Lean manufacturing is a systematic approach that aims to minimize waste and maximize value in the manufacturing process. It focuses on eliminating non-value-added activities, reducing inventory, improving efficiency, and enhancing overall quality.

Q4 : What is Six Sigma in manufacturing? A: Six Sigma is a methodology used in manufacturing to improve the quality of processes and products by identifying and eliminating defects and reducing variability. It employs statistical analysis and problem-solving techniques to achieve a high level of quality control.

Q 5: What is Just-in-Time (JIT) manufacturing? A: Just-in-Time (JIT) manufacturing is an inventory management strategy that aims to produce and deliver products exactly when needed, minimizing inventory and associated costs. It helps reduce waste, lead times, and storage requirements by synchronizing production with customer demand.

Q 6: What is Total Quality Management (TQM)? A: Total Quality Management (TQM) is a management philosophy that focuses on continuously improving the quality of products, processes, and services. It involves all employees in the organization, emphasizing customer satisfaction, employee involvement, and data-driven decision-making.

Q7: What is Computer Numerical Control (CNC) machining? A: Computer Numerical Control (CNC) machining is a manufacturing process that uses computerized control systems to operate machine tools. It allows for precise and automated control of various machining operations, such as cutting, drilling, milling, and turning.

Q8  What is the difference between batch production and mass production? A: Batch production involves producing a limited quantity of identical products in a specific sequence, while mass production refers to the continuous production of large quantities of standardized products. Batch production allows for more flexibility and customization, while mass production focuses on efficiency and cost reduction.

Q9: What is Quality Assurance (QA) in manufacturing? A: Quality Assurance (QA) in manufacturing refers to the systematic processes and activities implemented to ensure that products meet specified quality requirements. It involves inspecting, testing, and monitoring products throughout the manufacturing process to identify and rectify any defects or deviations from quality standards.

Q10: What is a Bill of Materials (BOM)? A: A Bill of Materials (BOM) is a comprehensive list of all the raw materials, components, sub-assemblies, and quantities required to manufacture a specific product. It provides a structured outline for production planning, inventory management, and cost estimation.

Q11: What are the casting defects?

Casting defects are common occurrences in the casting process that result in imperfections or flaws in the final cast product. Some common casting defects include:

1.     Porosity: This defect appears as small voids or bubbles in the cast metal caused by trapped air or gases. It weakens the structure and reduces the material's integrity.

2.     Shrinkage: Shrinkage defects occur when the casting solidifies and cools, causing uneven cooling and resulting in voids or cavities in the casting. It can lead to dimensional inaccuracies and reduced mechanical properties.

3.     Inclusions: Inclusions are foreign materials, such as sand, slag, or oxides, that become trapped in the casting during the pouring process. They can weaken the structure and affect the mechanical properties.

4.     Cold shuts: Cold shuts occur when two streams of molten metal do not fuse properly during the filling process, leading to a visible line or seam in the casting. It weakens the casting and affects its integrity.

5.     Misruns: Misruns happen when the molten metal fails to completely fill the mold cavity, resulting in an incomplete casting. It can be caused by insufficient pouring temperature or inadequate gating system design.

6.     Hot tears: Hot tears are cracks or fractures that occur during the cooling and solidification of the casting due to internal stresses. They are typically caused by inadequate mold rigidity or uneven cooling rates.

7.     Sand wash: Sand wash refers to the surface defect where the mold material is eroded or washed away by the molten metal, leaving a rough or uneven surface finish on the casting.

8.     Surface roughness: Surface roughness defects occur when the mold surface is not smooth or when the casting is not properly cleaned, resulting in an uneven or rough surface finish.

9.     Warpage: Warpage is the distortion or deformation of the casting from its intended shape. It can occur due to uneven cooling, improper mold design, or residual stresses in the casting.

10.  Flash: Flash is an excess metal or thin fins that are formed at the parting line of the mold due to excessive molten metal or mold misalignment. It needs to be removed to achieve the desired casting shape.
