Reliability Centered Maintenance (RCM) was initiated by the commercial aviation industry and then adopted by the U.S. military in the 1970s and then by the U.S. commercial nuclear power industry (in the 1980s) followed by other commercial industries and fields in the early 1990s.
RCM is defined by the technical standard SAE JA1011, as ‘‘an engineering framework that enables the definition of a complete maintenance regime. It regards maintenance as the means to maintain the functions a user may require of machinery in a defined operating context''.
17. Do you know what is a Vernier Scale?
This is used to measure very small unit with greater accuracy. It consists of a primary scale and a vernier scale.Vernier scale slides on the primary scale.
18. Tell me what was the workload like in your previous engineering department?
It is imperative that you do not complain about the workload in your previous job, even if it was taxing. Illustrate your efficiency; explain how you manage your time and prioritise tasks.
19. Tell me what Are The Types Of Manufacturing Systems?
The oldest type of manufacturing system is the custom manufacturing where a person or a machine makes a certain product tailored to a specific need. A shoemaker is an example of this system. Modern manufacturing have intermittent, continuous or flexible production systems.
20. Tell us what are Section lines?
Section lines are thin lines and used to show the cut surface of an object in sectional view.
21. Tell us what is software scope?
Software scope is a well-defined boundary, which encompasses all the activities that are done to develop and deliver the software product.
The software scope clearly defines all functionalities and artifacts to be delivered as a part of the software. The scope identifies what the product will do and what it will not do, what the end product will contain and what it will not contain.
22. Tell us what Are The Maintenance Concepts And Strategies?
Several maintenance concepts were developed in different parts of the world that are usually based on cultural and philosophical backgrounds. These trends encompass other strategies and technologies of maintenance. Some of these concepts are briefly introduced below:
☛ Total Productive Maintenance
☛ Reliability Centered Maintenance
☛ Maintenance Strategies
23. Tell us what do you get out of engineering that you couldn't get from any other kind of work?
You could talk about one engineering achievement that you are especially proud of, or you could explain how day-to-day aspects of the work stimulate you. If it is the latter, you should again tailor this to the role for which you are interviewing.
24. Tell us what Is Maintenance And Manufacturing?
Maintenance is one of the major activities in manufacturing as it highly influences production quality and quantity and directly affects production cost and customer satisfaction. As new manufacturing technologies emerge and global communication advances, new maintenance practices are developed to cope with these changes.
This is an ideal opportunity to depict several key qualities such as attention to detail, effective communication and creative thinking. You should come to the interview prepared with an example.
26. Please explain what Are The Main Advantage Of Fms?
The main advantage of FMS is its high flexibility in managing manufacturing resources. The resulting gains are numerous including:
☛ Reduced manufacturing cost,
☛ Greater labor productivity,
☛ Greater machine efficiency,
☛ Improved quality,
☛ Increased system reliability,
☛ Shorter lead times.
However, FMS implementation requires a large initial capital and substantial preplanning. It also requires high skilled labor.

It is the ratio of drawing to the object. R.F=Length of the object in the drawing /Actual length of the object.
33. Tell us what Is Maintenance In Manufacturing?
Maintenance in the manufacturing environment is one of the most complicated types of maintenance in comparison to construction, transportation and service business. Manufacturing is becoming highly competitive with extremely high pressure in reducing cost and increasing value of assets and improving the quality of outcomes (products). Manufacturing systems has grown over the years to be parts of global networks and supply chains. All of these changes in the manufacturing business have put maintenance in a great pressure on developing more effective and efficient operations.
Other special feature of manufacturing environment that makes it distinct from other environment is its complicated interrelation with large number of stakeholders, internal and external. The management structure in manufacturing environment is usually highly structured with many several decision layers and many parallel functional areas.
34. Tell us what is Engineering Drawing?
