Chapter 3 : Manufacturing Division

(MFD)INTRODUTION

This is the main division and probably can be called as heart of the company. This Caters to the needs of all other divisions. In other words, it satisfies the needs of the internal customers by supplying the individual jobs which then be assembled in the respective division.

CLASSIFICATION

In order to identify and to carry out the operations depending on the difficulties involved in handling etc., MFD is Classified into three cells.

CELL 1:

This is also know as heavy part cell. Some of the machines coming under this cell are:

Waldrich Siegen, Waldrich Coburg, TMC 800, TMC 1250, Noble and Lund, HMT Radial Drilling machine, etc.

CELL 2:

This is also known as medium part cell. Some of the machines Under this are TMC 500, SIP, Nissin, VMC 500, etc.

CELL 3:

This is also known as small part section. Some of the machines coming under this cells are:

Lathe, Milling machines, Grinding machines, etc.

Page 15: Internship2

HOW DOES MANUFACTURING DIVISION WORK?

As manufacturing division follows ISP rules, there is a proper sequence in which it works and can be given as below:

i. Engineering Methodii. Material Planningiii. Manufacturingiv. Quality Assurance

1. Engineering Method:

When MFD takes up an assignment from the internal customer, it has to be given a component manufacturing order number (CMO no.) in addition to the work order number which is already entitled by the concerned division and this work order number indicates the external customer to whom the job belongs. The main purpose of giving CMO no. is to identify the division to division from which order is taken. It also indicates the demand for that particular job.

The CMO no. for the following division are:

For MCD - ‘2’ for regular items

For SMD – ‘3’ for regular items

For CMD – ‘5’ for regular items

Each Component which is used for the manufacturing of the part is given a communication part number.

Example : A simple communication part no. would look like – ‘32002422’

The order also contains the quality required, time to be taken for manufacture and the cell to be used to manufacture.

15

Page 16: Internship2

Concept of Process Sheet:

Process sheet is the written format of the component drawing are really a complicated one for the operations to understand, so a written format of the actual drawing helps the operator to perform the operation in a particular manner without any spoilage of the work.

The contents present in the process are as follows:

I. Raw material:There is a particular coding for each raw material and they are indicated in the process sheet, so that operator can get the same material as mentioned by engineer in the form of coding on the process sheet.Examples: Low carbon steel has a coding as C2, High carbon steel has a coding as C1, Tool steel has a coding as T1, Nitriding steel has a coding as N1.

SEQUENCE OF PROCESS

The manufacturing of a component involves various operation such as turning, drilling, tapper turning, taper boring, boring, milling, grinding etc., these operations are called as machining processes. The particular sequence of process must be followed in order to get the component as given by the drawing. The operation. This sequence of processes is mentioned in the process sheet as shown below;

a.) Serial no. – it is the increasing order starting from initial operation till the final operation.

b.) Machine no. – the particular machine, which has to be used to carry out the process.

c.) Description of operation – this involves the way in which the operation has to be done and even the type of surface finish required is also defined.

Duration of operation, the approximate time which could be utilized for the particular operation is also mentioned in the

16

Page 17: Internship2

process sheet. Usually duration of operation involves only two parts, setup time and operation time.

Sometimes it may be needed to use special tool to obtain complicated shapes as indicated in the drawing and this has to be mentioned in the process sheet, so that operator will not be in dilemma about the way to obtain the particular shape.

The proper planning of material storage and even handling is very important in any organization. The material handling engineer has to take care of the materials and even has to analyze the requirement of materials before purchase.

After engineering analysis, the order is placed at material management section of MFD. The engineer has to decide about the procurement of the material such as bar stocks, casting, weldaments and other components as per the specification in the process sheet. If there is any shortage of material, it is needed to be informed and proper step must be taken to replace it. The raw material for the bed, Knee, column, spindle etc., is castings which are done in the company’s foundry, if its weight is less than 1 ton otherwise order is given to outside sub-contactor.

For storing of standards parts used in manufacturing, there is a separate store room, where the components are kept in a systematic manner based on communication part number. This is done according to the specification of ISO 9001, which says that the right things at right place is the key of successful implementation of ISO 9001.

materials is then passed to the machining cell where process on the materials are carried out as explained in the process sheet. The inspection of the job in between the processes may even be carried out as mentioned in the process sheet.The manufacturing division has a ‘tool crib’ from where the various tools are issued as required for the operation. The tools are arranged in a particular format and bins are provided for smaller tools and larger tools are placed in convenient places.The ‘tool crib’ follows ISO9001 rules strictly and if there is any tool spoilage then it has to be taken in writing from the operator who has been working on with that tool.There is a store for issuing smaller parts like screws, nuts, bolts, gears, etc., that is of minimum use in case of manufacturing division, since no assembly work is carried out in this division. The final product after passing through the mentioned machines, performing various operations on it, is then given for panting.

MARKING OUT : Marking out or layout is the process of transferring a design or pattern to a work piece according to given drawing, as the first step in manufacturing process.Marking out consist of transferring the dimension from the drawing to the work piece in preparation for the next setup, machining or manufacture.

Typical tools include;

Surface plate or Marking out table: Provides a true horizontal flat surface on which work piece can be supported.

Angle Plates: Assists in holding the work piece perpendicular to the table.

24

Page 25: Internship2

Scriber: It is equivalent of a pen or pencil, it literally scratches the metal surface leaving behind a fine, bright line.

Height Gauge or Scriber block: Allows lines to be scribed at a preset distance from the work table surface.

Surface Gage: An ungraduated comparison measuring tool that performs much the same function as the vernier height gage. It is often used in conjunction with a dial indicator and a precision height gage.

MACHINING: Machining is any of various processes in which a piece of raw material is cut into a desired final shape and sized by a controlled material-removal process. The many processes that have this common theme, controlled material removal, are today collectively known as subtractive manufacturing, in distinction from processes of controlled material addition, which are known as additive manufacturing. Exactly what the “controlled” part of the definition implies can vary, but it almost implies the use of machine tools (in addition to just power tools and hand tools).

Types of Machining Operation:There are many kind of machining operations, each of which is capable of generating a certain part geometry and surfaces texture.

In turning, a cutting tool with a single edge is used to remove material from a rotating work piece to generate a cylindrical shape. The speed motion is provided by rotating the work piece and the feed motion is achieved by moving the cutting tool slowly in a direction parallel to the axis of rotation if the work piece and depth of cut is given my moving cutting tool in direction perpendicular to the axis of rotation of the work piece.

25

Page 26: Internship2

Drilling is used to create a round hole. It is accomplished by a rotating tool that typically has two or four helical cutting edges. The tool is fed in a direction parallel to the axis of rotation of tool into the work piece to form the round hole.

In boring, a tool with a single bent pointed tip advanced into a roughly made hole in a spinning work piece to slightly enlarge the hole and improve its accuracy, It is a fine finishing operation used in the final stages of product manufacture.

In milling, a rotating tool with multiple cutting edges is moved slowly relative to the material to generate a plane or straight surface. The direction of the feed motion is perpendicular to the tool’s axis of rotation. The speed motion is provided by the rotating milling cutter. The two forms of milling are:I. Peripheral MillingII. Face Milling

Other conventional machining operation include shaping, planning, broaching and sawing. Also, grinding and similar abrasive operation are often included within the category of machining.

HEAT TREATMENT :Heat treatment is the process of heating and cooling metals to achieve desired physical and mechanical properties through modification of their crystalline structure. The temperature, length of time, and rate of cooling after heat treatment will all impact properties dramatically. The most common reason to heat treatment include increasing strength or hardness, increasing toughness, improving ductility and maximizing corrosion resistance.

26

Page 27: Internship2

INDUTION HARDENING :

Scope: Applicable to heat treatment of parts/components manufactured from raw materials.

4. PAINTING:Painting is common for all the departments. It is placed with in the MFD but at a suitable location to which the transportation of job from various departments may not be in a problem. Painting of the job as per customer specification is done and then passed on to the processes. In painting section, spray-painting technique is used. During spray painting, the tiny particles of paint in the form of jet is ejected from the gun which impacts on the job which has to be painted. There is a high possibility of these tiny particles spilling out to the atmosphere, which is hazardous to worker in this section. In order to avoid this, the updraft and lower draft is provided through which the continuous water circulation is maintained and this absorb the paint particles from the atmosphere, thereby providing a safe working condition.

31
