What Does Engineering Mean?
Engineering is defined as a subject that makes use of principles based on science to construct, design various types of machinery and also transportation facilities like bridges, flyovers, roads, automobiles, buildings and a lot more things around us.
The Latin word for Engineering means ‘to be clever’. Engineers must have a thorough understanding of mathematics, physics, and computer applications like simulations and computer-helped design.
What Does Engineering Drawing Mean?
An Engineering Drawing is a Graphical Representation of thought used to convey various ideas, data and information which is necessary for the basic construction of types of machinery, various structures, functional systems, roads, bridges, automobiles, etc. with the help of geometric lines, curves and shapes.
In simple words, an Engineering Drawing is a Graphical Language of Lines and Shapes.
What Is The Need/Use For Engineering Drawings?
Engineering Drawings are considered as the language of the Engineers. This type of drawing proves to be a medium of communication between the technicians and fellow engineers.
Engineering Drawings represent an object on a plane surface that very precisely determines the curves, shapes, lines, sizes, and all the required informative data for the construction, inspection, manufacturing and maintenance of a designed project.
Basic Requirements for Engineering Drawings
The basic requirements for Engineering Drawings are:
- Mastered art of Projection
- Three-dimensional perspectives of vision
- Correct use of curves and lines
- Speedy at drawing
Different Types Of Engineering Drawings
- Free Hand Sketch
- Detailed Drawings
- Part Drawings
- Assembly Drawings
- Collective Drawings
- Collective Single Part Drawings
- Collective Assembly Drawings
Free Hand Sketching
The art of engineer designing ideas with no use of traditional mechanical drawing tools like- scale, ruler, compass, set square, protractor, divider, etc.
This is a type of drawing that involves only the use of pencils, erasers, a plain and a grid sheet.
It includes straight lines, curved lines, arcs, circles, elliptical figures.
Detailed Drawings
A detailed drawing is a type of Engineering Drawing that includes a single component, this part of the Engineering Drawing includes the assembly part of the design of a project.
It provides a complete and detailed description of the dimensions of a system. It includes details about all of its parts and details of how the project is manufactured.
Information regarding the uses and needs to create the parts of the machinery are also mentioned in this type of drawing.
Information regarding the exact sizes and shapes, type of materials finishing of the system, resistances and necessities of every part of a system are mentioned.
Part Drawings
In Engineering a separate drawing of all the parts of the machinery or the project is to be drawn. These are the parts that will be assembled to form the final desired product.
A Part Drawing must show the dimensions, resistances, materials, finishing, etc. of the project.
Assembly Drawings
All the required and necessary information of the assembly of the machinery of the product or project must be included and mentioned in this type of drawing. A separate list of the parts must be mentioned which will later be put or assembled to form the final desired product.
An item number will be associated with every part in the assembly drawing to identify every part in the key.
Collective Drawings
All the assembly drawings are collected together called a collective drawing. Each item of the drawing is given an item or code number for easy identification.
Collective Single Part Drawings
This set of drawings consists of part drawings that are similar but different from one another by some details.
Collective Assembly Drawings
It consists of final assembled product drawings.
Information Present on a Detailed Engineering Drawing
- Name of the Part
- The angle of Projection.
- Name of Material used.
- The scale of the drawing.
- Date of design.
- All the views of the design (front view, left side view, right side view, top view, bottom view, back view.)
- An isometric view of the design is also required.
- Required necessary dimensions (Width, Depth, Height, Volume, Size, Area, Length, Breadth, etc.)
Common Engineering Drawing Tools
- Divider
- Pencils
- Protractor
- French curves
- Eraser
- Compass
- Drawing sheet
- Drawing board
- Mini drafter
- T square
- Templates
- Set squares
- Clinograph
Conclusion
Having a brief idea about all the instruments used in Engineering Drawing is a must for all the students pursuing a degree in Engineering.
The various types of drawings in this field are essential to know by an individual. Engineering is the basis of all the structures and vehicles we see around us. Even in chemistry, engineering plays a very important role.
Engineering is a vast topic and is of various kinds. This topic has a lot of scope in today’s growing world of skyscrapers, cars and bikes and various chemicals evolving in Chemistry.
