GROUP LAYOUT IN MANUFACTURING PLANT

In group layout , the existing job shop / batch manufacturing shop is partitioned in a few groups of machines where each group produces its associated families of components . Group Technology (GT) philosophy uses similarity of components from the processing point of view to create component families. By using the philosophy, a job-shop is transformed into a group technology environment which facilitates optimization of production scheduling.

The essence of GT makes use on similarities in recurring tasks in three ways.

1. By performing similar activities together there by avoiding wasteful time in changing from one unrelated activity to the next.

2. By standardizing closely related activities there by focusing only on distinct differences and avoiding unnecessary duplication of effort.

3. By efficiently storing and retrieving information related to recurring problems thereby reducing the search time for the information and eliminating the need to solve the problem again.

It can be noted that the four components are the representative components of the component facilities.

Advantages Of Group Layout are :

1. Reduction in machine set-up time and cost.

2. Reduction in material handling cost.

3. Elimination of excess work-in-process inventory which subsequently allows the reduction in lot size.

4. Reduction in through-put time.

5. Simplification of production planning functions, etc.

Disadvantages OF Group Layout :

1. Change of the existing Layout to GT Layout is time consuming and costly.

2. Inclusion of New components in the existing component families requires through analysis.

3. Change of input component-mix may likely to change cell structure.

4. Change in batch -sizes may change number of machines for any machine type.

MELTING FURNACES FOR FERROUS METALS : CUPOLA AND ITS WORKING

Various types of melting furnaces are used in different foundry shops, depending upon the quantity of metal to be melted at a time, and the nature of work that is carried out in the shop. The primary objective in cupola is to produce iron of desired composition, temperature and properties at the required rate in the most economical manner. Besides, this furnace has many distinct advantages over the other types, e.g., simplicity of operation, continuity of production, and increased output coupled with a high degree of efficiency. Description Of a Cupola : The Cupola Furnace consists of a vertical, cylindrical steel sheet, 6 to 12 mm thick, and lined inside with acid refractory bricks or acid tamping clay. The refractory bricks or the tamping clay used consist of silicon oxide acid (SiO2) and alumina (Al2O3). The lining is generally thicker in the lower where the temperatures encountered are higher than in the upper region. The shell is mounted either on a brick work fo...

SIMPLE CARBURETOR - CONSTRUCTION AND WORKING

CONSTRUCTION OF SIMPLE CARBURETOR : The main Components of Simple Carburetor are : Float Chamber, float, nozzle, venturi, throttle valve, inlet valve, and metering jet . In the float chamber, a constant level of petrol is maintained by the float and a needle valve. The float chamber is ventilated to atmosphere. This is used to maintain atmospheric pressure inside the chamber. The float which is normally a metallic hollow cylinder rises and closes the inlet valve as the fuel level in the float chamber increases to certain level. The mixing chamber contains venturi, nozzle and throttle valve. The venturi tube is fitted with the inlet manifold. This tube has a narrow opening called venturi. A nozzle is provided just below the centre of this venturi. The nozzle keeps the same level of petrol as that of the level in the float chamber. The mixing chamber has two butterfly valves. One is to allow air into the mixing chamber known as choke valve. The other is to al...

Advantages And Disadvantages Of Air Refrigeration System :

Advantages Of Air Refrigeration : 1. The refrigerant used namely air is cheap and easily available. 2. There is no danger of fire or toxic effects due to leakages. 3. The weight to ton of refrigeration ratio is less as compared to other systems. Disadvantages Of Air Refrigeration : 1. The quantity of Refrigerant used per ton of refrigeration is high as compared to other systems. 2. The COP of the system is very low. Therefore running cost is high. 3. The danger of frosting at the expander valves is more as the air contains moisture content.
