A mechanical engineering drawing is the subcategory of the technical drawings. The main purpose here is to convey all the necessary information for manufacturing a part of a product. All the engineering drawings utilized standardized symbols and languages, making it easier to understand all the drawings with little or no personal clarification potential.
What Is The Purpose Of Engineering Drawings?
As you already know, this is a technical drawing, so it contains all the information for building and welding an assembly or manufacturing a part. This information includes numbers, dimensions, parts names and many more. When the manufacturing engineer receives the drawing from an engineering drawing company, he begins the production without thinking twice.
How To Make The Engineering Drawings?
In the past, people used to sit down right in front of the drawing board to create drawings by using calipers, papers, rulers and many more. But these days, contemporary manufacturers don’t want such drawings made through these instruments. Why is that? The majority of the machinery utilizes CNC systems that can read all the information straight through the files. This will produce a cutting program accordingly.
Doing all the drawings done by hand will be time-consuming and add more manual work for the manufacturing engineers. So, there is only one option that engineers can use: the CAD or Computer-Aided Design software, as it offers many benefits. You can use CAD for producing drawings right from scratch. But the most-easiest option is to first create a 3D model and make the drawings through that.
This software generates all the views in a few clicks, and all is left for you to do is add the dimensions. When models are available, it will be easier for you to appraise the drawings for modification.
Different Types Of Lines
When you take the engineering drawing services, you will notice that these drawings have different lines. These lines can show both hidden and visual edges of the center lines, parts, and many more. Now, let’s learn about these detailed lines.
- The Continuous Line: The continuous line or the drawing line is the most common line type. It signifies the bodily boundaries of a product or object. In simple words, continuous lines are used to sketch the objects. The thickness of the lines varies greatly, and the exterior contour uses thick lines, and the interior ones use thin lines.
- Hidden Lines: These lines can show something visible in the sketches. For instance, the hidden lines can display the dimension of an interior step within a turned part without utilizing a cut-out view or a section.
- Center Lines: These lines can show the balanced properties and the hole of the parts. Displaying symmetricity will lessen the sizes and make the whole drawing easier to read and eye-pleasing.
- Extension Lines: The extension lines explain what is measured. The dimension line contains two points between the measurement at the top lines and extension lines.
- Break Lines: The break lines show a view has been wrecked or broken. When you have a 10mm wide, 3000 mm long, and has symmetric properties, using the break lines will provide you with all the information without taking up too much space.
Mechanical Engineering: What Exactly Is It?
By now, you have understood what mechanical engineering drawing is. But the main question here is, “What is Mechanical Engineering?” In simple words, it is the study of systems and objects in motion. The area of mechanical engineering connects all the elements of modern life, including the human body, a highly complicated machine. In this area, mechanical engineers analyze all their work by utilizing the principles of force, motion, and energy. It ensures that design performs reliably, safely, and efficiently at a competitive cost.
Final Thoughts
Mechanical engineering drawings are a massive part of an engineer’s work, and these drawings contribute around 20% of the engineer’s work time. They aid engineers in manufacturing a product or part quickly and effectively without issues or mistakes.
