About this course
There are various ways to approach quality control (QC) and this free online course discusses these approaches as well as the evolution of quality control techniques. You will learn about different components such as Quality of Conformance, Quality of Performance, Quality of Design and how quality characteristics are chosen for developing important control charts. The material describes and discusses the seven tools of quality management and the basic approach to statistical process control (SPC). You will analyze why it is important for organizations and manufacturers to maintain good quality products and services and then move on to the different quality control charts used for SPC in production processes. This free online course also covers the relevance of plotted values on x- and y-axes for sample control charts. This course then outlines in detail the different types and functions of control charts for attributes, as well as their variables. You will study the importance of mean control and range control charts, as well as how to develop a methodology for these charts. You will learn how to examine the relationship between productivity and work-study, as well as how they can be used favorably to improve the economy. Quality control skills are vital if manufacturers want to improve products, test them for variations and help train employees to reach and surpass certain standards.

This course then shows you how to work out much lubricating oil a gas turbine requires and consumes. We compare the two types of lubricating oil for gas turbine applications: standard and corrosion inhibiting. We demonstrate the harsh conditions experienced by lubrication oil in gas turbines: extreme heat, high contamination and inadvertent mixing with other substances. We cover two types of lubrication systems (wet sump and dry sump) while using a lube oil system schematic to explain the lube oil flow and components of the lube oil and lube scavenge subsystems. We lay out the characteristics, requirements, maintenance and handling of fuel before comparing its types: liquified natural gas (LNG), liquified petroleum gas (LPG), ethane and pure hydrogen. After establishing the functions and components of the fuel system, the course teaches you the requirements for a marine gas turbine engine: starting, steady running requirements and engine acceleration and deceleration. We can help you to master detection methods used for typical transducer faults like speed and temperature transducers. This course also teaches you the spark ignition system’s working features and functions as you become familiar with power turbines and the significance of the synchro-self-shifting (SSS) clutch in starting them up. We unpack epicyclic gears (star, planetary and solar) and demonstrate the advantages of using multiple-planet wheels. We then take you through more clutches: twin-disk, airflex, hydraulic and sprag. We explain the purpose of the ‘bleed air’ and ‘intake and exhaust’ systems before delving into the data-processing aspect of the automated central operating systems (ACOS). This free online engineering course suits anyone interested in the inner workings of gas turbines, particularly those who care about the planet and want to keep it powered with clean energy. In machining mechanics, the basic chip formation process by the removal of material from a workpiece by the action of a wedge-shaped cutting edge of the tool is considered. The objective of this study is to provide an analytical basis which relates cutting forces, tool stresses, and temperature, etc., to the cutting conditions such as the cutting speed, size of cut, cutting tool geometry, and the material properties of the workpiece and the tool. The course contains discussion of statics, kinematics and kinetics of the cutting process. Experimental findings relevant to mechanics of the process will also be discussed. The course will also include an introductory discussion on non-traditional machining processes. Non-traditional machining processes are now being widely used to generate intricate and accurate shapes in materials, like titanium, stainless steel and other difficult-to-machine alloys having higher strength, hardness and other diverse material properties.
