IED means the Industrial Engineering Division. The main function of IED is that the customer handling. At first when a party/customer (personnel/government/non-government institute/factory) needs to make a job, it comes to BITAC and meets with IED section. Sometimes all operations of the job can not be performed in BITAC. In that case, a quotation form is given to the party and that operation is performed from any outer shop. Then IED estimates approximate cost of the job or product according to the drawing or sample and number of products.


 The total cost consists of material cost, casting cost (if necessary), matching cost (depreciation cost, electricity bill, salary of the workers), overhead cost (25% of total cost and it ultimately goes to Bangladesh Bank), emergency cost (if necessary, generally 10% of the total cost), packing cost (if necessary) and transport cost (if necessary). 


If the party does not select any material then IED estimates the required strength of the material according to its purpose and finally selects the material with required strength and property.
After estimating the total cost for the job, IED offers a price to the party. If the party agrees to it, then the party places a work-order to the IED. For a govt. institute/factory, the total cost can be paid after finishing the job. But for a non-govt. institute/factory, half of the total cost should be paid instantly.
Lastly IED hands over the quotation form and work-order to PCD by a job file.

PCD stands for Production Control Division. It is the heart of BITAC. PCD gets any order of a job from the party through IED. IED hands over the work order, quotation form and job’s drawing/sample provided by the party.
IED mainly operate customer handling and PCD maintains internal procedure. That means the rest procedure before handling to customer is done in the PCD section.
PCD makes an operation sheet for the job and supplies the copy of operation sheet to each floor in-charge in which the job should be replaced. PCD also supplies material

from the store. PCD selects the required time for each shop. The required time that is given for each shop to perform their duties depends upon the total time within which the job should be delivered.
Then according to the operation sheet, the job goes under different operations in the different shops. PCD operates observes whether the processes are performed in each section in time or not.
When the job becomes ready for delivery then PCD gives a letter to the party through IED informing that the job is ready for delivery. PCD also sends forwarding bill to the accounts section and the accounts section sends formal bill to the party

IS means Inspection Section. When a job is made before heat treatment the job is placed in inspection section. After inspection it transfer to the heat treatment  shop. After heat treatment IS measures the jobs with measuring tools. Then they transfer to the machine shop.
Under the PCD section we used the tool store to about them. The main tools are places in the followings which are in the store.

“Equalizer connection is needed in lap winding armature but not in wave winding “ why ?

The equivalent circuit of a four point – pole dynamo with a simplex winding. The voltage induced in each path is assumed to both to be same and should be if the reluctance of each magnetic path is the same, so that the lines of flux cut by each inductor of each path are the same. However wear of the bearings or deflection of the armature shaft may cause the armature to be closer to some poles and farther from others, thus changing the length of the air gap, and therefore the reluctance of the magnetic circuits of the poles is not identical. This factors cause the voltage in the materials making up the magnetic circuit. These factors cause the voltage in each parallel path differ, and the unequal voltages in turn cause flow of a circulatingcurrent through the windings and brushes , undue heating of the armature and waste the power. To reduce the circulating current, points on the winding which should be at the same potentials are brought to the same potentials by connecting them with …



What are the advantages and disadvantages of hydraulic brakes?

Differentiate among progressive die, compound die and combination die.

Progressive die: The dies which performed two or more operations at different stages every time the ram descends is known as Progressive die.
The principle advantage of Progressive die is in the number of operations that can be achieved with one handling of the stock strip. The main disadvantage is that work pieces may become “dished” as they pushed through the die as they generally have very little support.

Compound die: A compound die differs from a progressive die in that it performs two or more cutting operations during one stroke of the press at one station only.

Compound dies are slower in operation than progressive dies but they have advantages for certain jobs, especially where tolerance are close (1)the cutting operation, by the action of the knockout plate ,ensures flatness of the blank.2 Large parts can be blanked in a smaller press if compound dies rather than progressive dies areused.
Combination dies:A die in which a cutting operation is combined with a noncutting operation …

Why a dc generator fails to build up voltage?



Boiler: A steam boiler is usually a closed vessel made of steel. Its function is to transfer the heat produced by the combustion of fuel to water and ultimately to generate steam.
Types of boiler:
           1. Fire tube or smoke tube boiler            2. Water tube boiler

                                          Figure: Boiler
Fire tube boiler: In fire tube steam boilers, the flames and hot gases, produced by the combustion of fuel pass through the tubes which are surrounded by water. Fire tube boilers are generally used for relatively small steam capacities and low to medium steam pressure. As a guideline fire tube boilers are completive for steam rates up to 12000kg/h and pressures up to 18 kg/cm².Fire tube boilers are available for operation with oil, gas or solid fuel.

Example: Cochran boiler, Locomotive boiler, Scotch marine boiler, Velcon boiler, simple vertical boiler.
