Engineering Graphs
Engineering graphs are visual representations used by engineers to analyze and communicate data, relationships, and designs. They can include various types such as line graphs, bar graphs, and pie charts, and are often used to illustrate trends, comparisons, and patterns in engineering processes and systems. These graphs are essential tools for decision-making, problem-solving, and conveying complex information in a clear and concise manner.

...They can also provide a lot of information regarding a technical solution, beyond the apparently visible. Accompanied by standardised ideograms or annotations, engineering drawings become the ideal mode of communication to convey information between the various parties involved in the design process and even the product development process. Owing to their versatile possible use, engineering drawings serve at minimum one of three purposes, frequently all of them at the same time: Figure 1.5 Rendered CAD model of a pillar drill. Communication Visualisation Documentation As an example, companies use engineering drawings, in either paper or digital form, to convey how to fabricate a part while taking all necessary specifications into account. For that reason, precision needs to be the foremost quality of such a manufacturing drawing. However, communicating a part’s manufacturing requirements and specifications is not the sole application. There are numerous interfaces across a company where a design solution needs to be communicated and visualised without ambiguity. This includes the following departments, depending on the specific industry branch: Mechanical design Electrical design Automation and control Research and development (R&D) Project management Purchasing Production Quality control Maintenance Service Usually all these departments are somehow involved in a product’s life cycle and therefore need a clear picture of the product. Engineering drawings represent the common communication medium and therefore can be considered to be one of the most important documents in an industrial company. Once a design is finalised, the design process needs to be diligently documented. One reason is to communicate the rationales behind a design decision, which can be understood even after years...

...They function like bar graphs in which the bars are replaced by a series of symbols that represent the quantity graphed. Each symbol represents a defined unit value. Since carefully chosen and easily recognized symbols add interest to statistical data, pictographs are successful with a general audience. It is best to use only whole symbols rather than a fraction of, let’s say, a tractor or a person, even though this practice results in generous approximations. After all, pictographs are meant to provide only an overall picture rather than minute details. Flow Charts While line graphs can guide the reader effectively through trends or changes in magnitude of one or more variables with time or changes in other variables, a flow chart can describe the steps or phases of a technical process or operation in graphical form. The flow chart highlights the sequence of steps or phases of the process and can specify the time required for these. Pictorial forms can add interest to these charts. A well-designed flow chart, as shown in Figure 9, can present a large number of facts clearly and simply, without extensive verbal descriptions. Drawings Drawings in a technical document serve numerous functions: they can help define an object by giving an overview, as in a technical description, and can clarify the relationship of the parts. Enlarged views, cutaways, or exploded views represent subdivisions of the whole into parts. In addition, drawings can illustrate or give examples. Even though the actual drawing of illustrations is a technical skill and not part of the writing skill itself, the writer should consider how drawings serve certain writing strategies as well as make certain that the visuals meet effective design standards. The following guidelines for effective figure legends and for clear and effective visuals also apply to drawings. Figure 9. Resolution process for modification requests. (From T. S. Kennedy, D. A. Pezzutti, and T. L...

...The latter is particularly useful if illustrations are involved. In industry and commerce all information must be produced in a way that is: Easy to understand with no risk of errors. Complete, with no essential details missing. Quick and easy to complete. These goals are best achieved by the use of standardized forms. By providing much of the information in the form of boxes which require a tick, the interpretation of hand-writing which may be difficult to read is removed. Manufacturing organizations are concerned with making the goods available to their customers at a price their customers are prepared to pay, and in delivering those goods in the correct quantities at the correct time. This involves teamwork within the organizations and close liaison with their customers and suppliers, and can only be achieved by the selection of efficient communication and the efficient handling of engineering information. 4.2 Interpretation of information (graphical) There are many ways in which information can be presented and it is essential to select the most appropriate method. This will depend upon such factors as: The information itself. The accuracy of interpretation required. The expertise of the audience to whom the information is to be presented. Much of the information required for the manufacture of engineering products is numerical. This can be presented in the form of tables where precise information concerning an individual item can be outlined. Sometimes, all that is needed is a general overview of a situation that can be seen at a glance. In this case the numerical data is most clearly presented by means of graphs and diagrams. There are many different types of graphs available depending upon the relationship between the quantities involved and the numerical skills of the user for the graph...
