Tools used in mechanical drawing

The instruments used in engineering drawing are: Drawing sheet. Drawing board. Mini drafter. T square. Set squares.

Electronic drawings save time and storing problem. With the help of the modern CAD software these professionals have been able to generate unique and flexible designs, models and diagrams without much hassle. These designs can also be effortlessly customized without creating a new one. Measuring tools are important for determining dimensions of any given object. You should always use the right tool for the job.

Your tool must be periodically calibrated against a working standard, usually once a year or so, depending on the tool and its level of use. Drafting templates are used when standard symbols are to be drawn repeatedly.

A drafting template is a flat piece of plastic with standard symbols cut in it. The drafting templates shapes are used as guides for drawing symbols on plans. Drafting and design have been around since the dawn of time. The earliest recorded history of engineering drafting was in B. Since then, and with the advent of paper, engineering drafting has been fairly analog.

The present trend is to go in for steel clips, if the size of the drawing paper is the same as that of the drawing board. Clips are used at all the four corners of the drawing board to clamp the paper. Adhesive tapes are also used for fixing the drawing sheet. Only pencil eraser is used. Soft India-rubber is the most suitable kind of eraser for pencil drawings. The eraser used should be such that the surface of the drawing paper is not spoiled in anyway.

It is desirable to use erasing shield to protect the nearby lines from being erased. The rubber crumbs formed after erasing should be swept away with a clean duster and should never be brushed off with hands. Use of eraser should be minimized by proper planning. Erasing Shield — It is a thin metal or plastic plate cut with slots, circles and curves of different dimensions. It helps to erase unwanted pencil lines without erasing the surrounding lines.

T- Square — It is composed of a long strip called blade, which is screwed rigidly at right angle to a shorter piece called head or stock. It is made of mahogany or pear wood, which is harder than the board wood. The head also has an ebony edge which slides against the working edge of the board. T- Square is used for making horizontal, vertical, inclined or parallel lines on the drawing sheet. Set-Squares — Set-squares are made of transparent plastic and are available in the shape of triangles, having a French curve or simply a gap cut in the body.

These are used for drawing short straight lines, measuring and drawing certain angles. A good combination of set-squares is 30 O x 60 O set square with a long edge of mm and a 45 O set squares with each edge of mm. Large Size Compass — The compass is used for drawing circles and arcs.

It consists of two legs hinged together at its upper end. A pointed needle is fitted at the lower end of one leg, while a pencil lead is inserted at the end of the other leg. The lower part of the pencil leg is detachable and it can be interchanged with a similar piece containing an inking pen. Both the legs are provided with knee joints. This has a blue part that can erase ink as well as Indian ink.

Sharpeners are available in a variety of different models. The blades in each are set to a different sharpening angle, depending on which type of pencil they are made for. You will not need a sharpener if you are using a mechanical pencil.

If you are yet not a professional and would like to learn technical drawing, then a guideline is highly recommended. The purchase of said guideline will most likely be recommended by whichever study program or professional apprenticeship you are doing. They can give you recommendations on which implements are best suited to get started.

Because of the globalisation of business, it is necessary for technical drawers to ensure they have their notes and annotations written in English on their drawings. Because not all technical terms to do with technical drawing are common knowledge, it is also important to pick up a dictionary to help you along. Trends Hand Lettering Guide.
