CAD DEPARTMENTMAJOR SOFTWARE RESOURCE:-

(a) Pro- Engineer:

PTC Creo, formerly known asPro/ENGINEERis a parametric, integrated 3D CAD/CAM/CAE solution created by Parametric Technology Corporation (PTC). It was the first to market with parametric, feature-based, associative solid modeling software.

(b)CATIA:

Itis a multi-platform computer-aided design (CAD)/computer-aided manufacturing (CAM)/computer-aided engineering (CAE) software suite developed by the French company Dassault Systmes.

(c)AutoCAD:

AutoCADis a computer-aided design (CAD) program used for 2-D and 3-D design and drafting.AutoCADis developed and marketed by Autodesk Inc. and was one of the initial CAD programs that could be executed on personal computers.

CAD DEPARTMENTANSYS:ANSYSis a general purpose software, used to simulate interactions of all disciplines of physics, structural, vibration, fluid dynamics, heat transfer and electromagnetic for engineers.Creo 3.o: Creois a family or suite of design software supporting product design for discrete manufacturers and is developed by PTC. The suite consists of apps, each delivering a distinct set of capabilities for a user role within product development.

Siemens NX:NX, formerly known asNX Unigraphicsor usually justUG, is an advanced high-endCAD/CAM/CAE software package originally developed bySiemens PLM Software.

It is used, among other tasks, for:Design(parametric and direct solid/surface modelling)Engineering analysis(static, dynamic, electro-magnetic, thermal, using thefinite element method, and fluid using the finite volume method).Manufacturing finished design by using included machining modules.

CAD DEPARTMENTBenefits of the CAD Software:1) Increase in the productivity of the designer:The CAD software helps designer in visualizing the final product that is to be made, it subassemblies and the constituent parts. The product can also be given animation and see how the actual product will work, thus helping the designer to immediately make the modifications if required. CAD software helps designer in synthesizing, analyzing, and documenting the design. 2) Improve the quality of the design:the CAD systems offer greater accuracy, the errors are reduced drastically in the designed product leading to better design. Eventually, better design helps carrying out manufacturing faster and reducing the wastages that could have occurred because of the faulty design.

CAD DEPARTMNT3) Better communications: The next important part after designing is making the drawings. With CAD software better and standardized drawings can be made easily. The CAD software helps in better documentation of the design, fewer drawing errors, and greater legibility.4) Creating documentation of the designing: Creating the documentation of designing is one of the most important parts of designing and this can be made very conveniently by the CAD software. The documentation of designing includes geometries and dimensions of the product, its subassemblies and its components, material specifications for the components, bill of materials for the components etc.6) Saving of design data and drawings: All the data used for designing can easily be saved and used for the future reference, thus certain components dont have to be designed again and again.

CAD DEPARTMENTPRODUCT DEELOPMENT AND LAUNCHING:

The creation of products with new or different characteristics that offer new or additional benefits to the customer.

Product development may involve modification of an existing product or its presentation, or formulation of an entirely new product that satisfies a newly defined customer want or market niche.

CHAPTER : 2TOOL DEPARTMENT

HEAD OF DEPARTMENT : Mr. PATRA SIR NO.OF EMPLOYEE : 10 (APPROX)

TOOL DEPARTMENTCIPET has elite collection of conventional and non conventional machine of high grade under same roof which is widely spread in area.In this workshop, dies and mould are prepared on CNC machine which are used by processing department further. all machine are operated by student and technical officer.

TOOL DEPARTMENTMAJOR CONVENTIONAL AND NON CONVENTIONAL MACHINE :(1) SURFACE GRINDING MACHINE:-Surface grindingis used to produce a smooth finish on flat surfaces. It is a widely usedabrasive machiningprocess in which a spinning wheel covered in rough particles (grinding wheel) cuts chips of metallic or nonmetallic substance from a workpiece, making a face of it flat or smooth.Principle :It is a finishing process that uses a rotating abrasive wheel to smooth the flat surface of metallic or nonmetallic materials to give them a more refined look or to attain a desired surface for a functional purpose.

TOOL DEPARTMENT IMAGES OF SURFACE GRINDING MACHINE:

TOOL DEPARTMENT(2) SHAPER MACHINE:-Ashaperis a type ofmachine toolthat useslinearrelative motion between the workpiece and asingle-point cutting tool to machinea linear tool path. Its cut is analogous to that of alathe, except that it is linear instead ofhelical.

TOOL DEPARTMENT(3) DRILLING MACHINE:-Drillingis acutting process that uses adrill bitto cut a hole of circularcross-sectionin solid materials. The drill bit is usually a rotary cutting tool, often multipoint. The bit ispressedagainst the workpiece and rotated at rates from hundreds to thousands ofrevolutions per minute. This forces the cutting edge against the workpiece, cutting offchips (swarf)from the hole as it is drilled.

TOOL DEPARTMENT(4) CNC MILLING MACHINE:-CNCmillsuse computer controls to cut different materials. They are able to translate programs consisting of specific numbers and letters to move the spindle (or workpiece) to various locations and depths. Many useG-code, which is a standardized programming language that many CNC machines understand, while others use proprietary languages created by their manufacturers.

TOOL DEPARTMENT(5)CNC LATH MACHINE:The design of a CNC lathe varies with different manufacturers, but they all have some common elements. The turret holds the tool holders and indexes them as needed, the spindle holds the workpiece and there are slides that let the turret move in multiple axis simultaneously. The machines are often totally enclosed, due in large part tooccupational health and safety issues.

TOOL DEPARTMENT(6) ELECTRIC DISCHARGE MACHINE:Electrical discharge machining(EDM), sometimes colloquially also referred to asspark machining,spark eroding,burning,die sinking,wire burningorwire erosion, is a manufacturing process whereby a desired shape is obtained using electrical discharges (sparks).[1]Material is removed from the workpiece by a series of rapidly recurring current discharges between twoelectrodes, separated by adielectricliquidand subject to an electricvoltage. One of the electrodes is called the tool-electrode, or simply the "tool" or "electrode", while the other is called the workpiece-electrode, or "workpiece".

TOOL DEPARTMENTBENEFITS OF UNCONVENTIONAL MACHINE OVER CONVENTIONAL MACHINE: LONG TOOL LIFE: Conventional machining process involved tool wearing as there is a physical contact between the tool and the work piece. In non-conventional process, this is not the case.ACCURACY:Non-conventional tools are more accurate and precise than the conventional tool.NOISE FREE:No noise pollution is created as a result of non-conventional methods as these tools are much quieter.AUTOMATION:Non Conventional Machine can be operated automatically once the programme is feed in to the CPU of machine and job is clamp.

Chapter 3PROCESSING DEPARTMENT

PROCESSING DEPARTMENTABOOUT PROCESSING DEPARTMENT:Processing is the Department in CIPET where the product are made by the different process under major precautions, in processing there are different type of materials which are used according to product requirement.Some of the plastic material which are used in processing are: Polyethylene terephthalate (PET), High density polyethylene (HDPE), Polyvinyle chloride (PVC), etc. In PROCESSING DEPARTMENT we got to observe many things like how a die is fixed in the mouding machine, how the raw materials are treated before taking use of it, how heavy parts are displaced within processing department with the help of chain and pully system.

PROCESSING DEPARTMENTMACHINE IN PROCESSING DEPARTMENT:(1) INJECTION MOULDING MACHINE:Injection mouldingis amanufacturingprocess for producing parts by injecting material into a mould. Injection moulding can be performed with a host of materials, including metals, (for which the process is calleddiecasting),glasses,elastomers, confections, and most commonlythermoplasticandthermosettingpolymers. Material for the part is fed into a heated barrel, mixed, and forced into a mould cavity, where it cools and hardens to the configuration of the cavity.After a product is designed, usually by anindustrial designeror anengineer, moulds are made by amouldmaker(or toolmaker) frommetal, usually eithersteeloraluminum, andprecision-machinedto form the features of the desired part.

PROCESSING DEPARTMENTIMAGES OF INJECTION MOULDING MACHINE:

PROCESSING DEPARTMENTADVANTAGES OF INJECTION MOULDING:-(1) Detailed Features and Complex Geometry:The injection molds are subjected to extremely high pressure. As a result the plastic within the molds is pressed harder against the mold compared to any other molding process. Due to this excessively high pressure, it is possible to add a large amount of details into the design of the part.Furthermore, due to high pressure during the molding process, complex and intricate shapes can easily be designed and manufactured which otherwise would have been too complicated and expensive to manufacture.(2) High Efficiency:- Once the injection moulds have been designed according to the customers specifications, the actual molding process is very quick compared to other methods of molding. Plastic injection molding process hardly takes times and this allows more parts to be manufactured from a single mold.

PROCESSING DEPARTMENT The high production output rate makes plastic injection molding more cost effective and efficient.(3) Enhanced Strength:-In plastic injection molding, it is possible to use fillers in the injection molds. These filler reduce the density of the plastic while it being molded and also help in adding greater strength to the part after it has been molded. In fields where parts need to be strong and durable, plastic injection has an option that other molding processes do not offer.(4) Automation to Save Manufacturing Costs:-Plastic injection molding is an automated process. A majority of the injection molding process is performed by machines and robotics which a sole operator can control and manage.

PROCESSING DEPARTMENT Automation helps to reduce manufacturing costs, as the overheads are significantly reduced.Furthermore, with reduced labor force the overall cost of manufacturing the parts is reduced and this cost saving can easily be passed on to the customer.(5) The Bottom Line:-Using injection molding also ensures the parts manufactured hardly require any work after the production. This is because the parts have more or less a finished appearance after they are ejected from the injection molds.

PROCESSING DEPARTMENT (2) EXTRUSION MOULDING:-Extrusionis amanufacturingprocess used to make pipes, hoses , drinking straws,curtaintracks,rods, andfibre. The granules melt into a liquid which is forced through adie, forming a long 'tube like' shape.The shape of the die determines the shape of the tube. The extrusion is then cooled and forms a solid shape. The tube may be printed upon, and cut at equal intervals. The pieces may be rolled for storage or packed together. Shapes that can result from extrusion include T-sections, U-sections, square sections, I-sections, L-sections and circular sections.One of the most famous products of extrusion moulding is theoptical fiber cable.

PROCESSING DEPARTMENTExtrusion is similar toinjection mouldingexcept that a long continuous shape is produced.Process showing extrusion process

PROCESSING DEPARTMENT(3)STRETCH BLOW MOULDING:-In stretch blow moulding PET bottles can be manufactured by using two production techniques: The single-stage (Injection Stretch Blow Moulding) and two stage processes (Reheat Stretch Blow Moulding).

Injection Stretch Blow MouldingIn the single-stage process the preform is injection moulded from PET resin in the same machine which will stretch and inflate it to form a finished bottle. Two distinct production stages are incorporated in one machine, with the preform being transferred from one stage to the other while still warm.

PROCESSING DEPARTMENTPARTS OF STRTCH BLOW MOULDING:-1.Preform(made from injection moulding)2.Mould3.Infrared heater4.Clamp5.Control panel6.Injection pinAdvantages:Very high volumes are produced.Little restriction on bottle design.Preforms can be sold as a completed item for a third party to blow.Disadvantages: High capital cost. Floor space required is high, although compact systems have become available.
