Task 1: As a maintenance manager at a plant, you are required to update the existing maintenance plan for on of the critical plant's systems. This entails defining economical and technically practical maintenance interventions while considering a high level of safety. What are the potential approaches for maintenance interventions that could be included in the curren maintenance plan? Provide definitions for each of them, outline their advantages and disadvantages, and support them with real-life examples. State two potential maintenance decision-making strategies you could adopt and clarify their steps and logic of implementation. Introduce and explain the concept of Prognostics and Health Management (PHM). Describe what PHM entails, as well as its benefits and expectations. Explain how the frequency of planned maintenance interventions can impact production and costs for a specific component. Clarify the process for selecting the best maintenance intervention approach for that component using the selected maintenance decision-making strategy. Create a thorough and cost-effective guideline for determining the optimal replacement age for the component.
Theory and Design for Mechanical Measurements
Measurement is a term that refers to analyzing a manufactured component regarding the degree of accuracy for dimensions, tolerances, geometric profile, roundness, flatness, smoothness, etc. Measurement always involves comparing the manufactured component or the prototype with a standard specimen whose dimensions and other parameters are assumed to be perfect and do not undergo changes with respect to time.Precisely in mechanical engineering the branch that deals with the application of scientific principles for measurements is known as metrology. The domain of metrology in general deals with various measurements like mechanical, chemical, thermodynamic, physical, and biological measurements. In mechanical engineering, the measurements are limited to mechanical specific such as length, mass, surface profile, flatness, roundness, viscosity, heat transfer, etc.
Basic principles of engineering metrology
Metrology is described as the science of measurement, precision, and accuracy. In other words, it is a method of measurement based on units and predefined standards.
