Sketch by Er. Abhisek Bhattacharjee


Introduction 

Freehand sketching is one of the effective methods to communicate ideas irrespective of the Branch of study. The basic principles of drawing used in freehand sketching are similar to those used in drawings made with instruments. The sketches are self explanatory in making them in the sequence.

Importance of Free Hand Sketching.

Free hand drawing has much importance in practical works because a draftsman has to check the drawings of every object from the engineer.

Principles of Free Hand Sketching.

Following principles should be followed for free hand sketching:

1. The object should be seen thoroughly and pondered over its objectives and concepts.

2. More detailed aspect is considered for selection of a view

3. Space is specified on a drawing sheet according to the sizes of views.

4. Firstly, the dim lines are drawn so that extra lines may be erased easily.

5.  Scale and ruler are not used in drawing, although, ratio and proportion of different parts of an object are considered.

6. Firstly, horizontal lines are drawn then vertical lines are drawn, and arcs and circles are drawn lastly.

7. After completing the diagram, a clear scale is written in some suitable manner.

Hydraulic Circuit by Er. Abhisek Bhattacharjee

The basis for all hydraulic systems is expressed by Pascal's law which states that the pressure exerted anywhere upon an enclosed liquid is transmitted undiminished, in all directions, to the interior of the container. This principle allows large forces to be generated with relatively little effort.  The purpose of a specific hydraulic system may vary, but all hydraulic systems work through the same basic concept. Defined simply, hydraulic systems function and perform tasks through using a fluid that is pressurized. Another way to put this is the pressurized fluid makes things work. The power of liquid fuel in hydraulics is significant and as a result, hydraulic are commonly used in heavy equipment. In a hydraulic system, pressure, applied to a contained fluid at any point, is transmitted undiminished. That pressurized fluid acts upon every part of the section of a containing vessel and creates force or power. Due to the use of this force, and depending on how it’s applied, operato...

Taguchi Methodology

Introduction Taguchi’s methodology is a statistical innovative approach to total quality management developed by Genichi Taguchi of Japan. When Japan began its reconstruction efforts after World War II, it faced an acute shortage of good quality raw material, high quality manufacturing equipment and skilled engineers. The challenge was to produce high quality products and continue to improve the quality under those circumstances. The task of developing a methodology to meet the challenge was assigned to Dr. Genichi Taguchi. Through his research in the 1950s and the early 1960s, Dr. Taguchi developed the foundations of Robust Design methodology and validated its basic philosophies by applying them in the development of many products. The Methodology Robust Design is an engineering methodology for improving productivity during research and development so that high quality products can be produced quickly and at low cost. Its use can greatly improve an organization’s ability to meet marke...
