WHY THIS PROJECT
From the very beginning of our engineering studies dream is to
envisage our self as a design engineer round the globe. Being an
engineering student we have always been interested towards
drawing and designing various field of engineering , our career
objectives include performing extensive research in engineering as a
design engineer being part of an organization which provide me
ample opportunity to do so .while doing summer training on
UNIGRAPHICS in CTTC, BBSR, we feel that without a design
project work our knowledge over UNIGRAPHICS will remain
incomplete, so we decided to do this project work “DESIGNING
OF CHAFF CUTTING MACHINE USING NX”, with direct
supervision in inspiration of our project guide
Er. Nilima Bhoi. As well as possible we try to explore our views
and ideas over the subject. We may not be certain about what new
design we have done in this project but confirm that what design
we have done is a complete new experience for us and hope the
experience gain by us through this project work will help us to
fulfill our dream. As possible as every effort has been made by us
to give a crystal clear view over the subject on reader’s mind.

ABSTRACT
Throughout the life cycle of engineering products, the uses of computers are prominent
and often have a central role. With the help of Computer Aided Designing, Computer
Aided Manufacturing and the application of various computer software’s in engineering I
analyze the robustness and the performance of the components, which encompasses
simulations, validations and optimization of products and manufacturing tools. This
assignment clearly demonstrates the significance of CAD and CAM solutions.
Hence, we joined the UNIGRAPHICS course to enhance our knowledge about design and
manufacturing.
Being students of UNIGRAPHICS course, only gaining knowledge about design software
was not enough. So we realized it is also important to implement our knowledge into a
project with our knowledge, what we have learn in this course and our innovative ideas.
Hence we came up with the idea of designing of a model of chaff cutter with the available
resources in our work unit. This project on chaff cutter provided us with an excellent
opportunity to brush our knowledge on designing.

INTRODUCTION TO CAD/CAM
The Modern world of design, development, manufacturing so on, in which we have stepped
can’t be imagined without interference of computer. The usage of computer is such that,
they have become an integral part of these fields. In the world market now the competition
in not only cost factor but also quality, consistency, availability, packing, stocking, delivery
etc. So are the requirements forcing industries to adopt modern technique rather than local
forcing the industries to adapt better techniques like CAD / CAM / CAE, etc. The Possible
basic way to industries is to have high quality products at low costs is by using the computer
Aided Engineering (CAE), Computer Aided Design (CAD) And Computer Aided
Manufacturing (CAM) set up. Further many tools is been introduced to simplify & serve
the requirement UNIGRAPHICS, PRO-E, UG are some among many.
This penetration of technique concern has helped the manufacturers to
a) Increase productivity
b) Shortening the lead-time
c) Minimizing the prototyping expenses
d) Improving Quality & better products
CAD, CAM & CAE
CAD:-Computer-aided design (CAD) refers to the use of computer tools to assist
engineers, architects and other design professionals in their design activities. It is the main
geometry authoring tool within the Product Lifecycle Management (PLM) process and
involves both software and sometimes special-purpose hardware. Current packages range
from 2D vector based drafting systems to 3D parametric surface and solid design modelers.
CAD is sometimes translated as "computer-assisted drafting", "computer-aided drafting",

or a similar phrase. Related acronyms are CADD, which stands for "computer-aided design
and drafting"; CAID, for Computer-aided Industrial Design; and CAAD, for "computer-
aided architectural design". All these terms are essentially synonymous, but there are some
subtle differences in meaning.
Basically CAD is not just a drafting tool, its a very accurate and robust design tool too.
Due to the complexity of computations in design methodology, the power of computers is
leveraged to compute solutions to complex problems like stress analysis, shear analysis,
thermal analysis and fluid flow analysis. The CAD offers very simple, easy to use, less
time consuming and clean methods to study and evaluate the design process and arrive at
a close-to-perfect design. CAD and CAM can even be used in food processing.
CAM :- Computer-aided manufacturing (CAM) refers to the use of computer systems
for the control of robotics and tools during the product manufacture. Integrating CAM with
CAD systems provides quicker and more efficient manufacturing processes. This method
is applied in different areas. In CNC manufacturing the CAM system is used to simplify
the machining and designing process. In most cases the CAM system will work with a
CAD design made in a 3D environment. The CNC programmer will just specify the
machining operations and the CAM system will create the CNC program. This
compatibility of CAD/CAM systems eliminates the need for redefining the work piece
configuration to the CAM system. In other words: CAM software usually comes with a
machine such as a lathe or chisel. The entire system tends to be extremely expensive. (A
lathe and computer system with software will cost in excess of $1 million). CAD/CAM
systems offer the advantages of increased programming accuracy, geometric conformance
to design parameters, ability to make minor and often major changes to part configuration
and programming metrics within the same system. CAD/CAM systems utilize either
"wireframe" or "solids" for the part feature generation necessary for post-processing
intermediate code files derived from cutter tool paths into usable "NC" code readable by
numerical control machines. Wireframe geometry can be either in two or three dimensional

planes, while solids are in 3d. CAD/CAM is used widely across the world at schools and
companies who design, innovate and manufacture new products.
CAE:- Computer-aided engineering (often referred to as CAE) is the use of information
technology for supporting engineers in tasks such as analysis, simulation, design,
manufacture, planning, diagnosis and repair. Software tools that have been developed for
providing support to these activities are considered CAE tools. CAE tools are being used,
for example, to analyze the robustness and performance of components and assemblies. It
encompasses simulation, validation and optimization of products and manufacturing tools.
In the future, CAE systems will be major providers of information to help support design
teams in decision making.
In regard to information networks, CAE systems are individually considered a single node
on a total information network and each node may interact with other nodes on the network.
The term CAE has also been used by some in the past to describe the use of
computer technology within engineering in a broader sense than just engineering
analysis. It was in this context that the term was coined by Dr. Jason Lemon, founder of
SDRC in the late 70's. This definition is however better known today by the terms CAx
and PLM.
CAE areas covered include:
• Stress analysis on components and assemblies using FEA (Finite Element
Analysis);
• Thermal and fluid flow analysis [[Computational fluid dynamics]] (CFD);
• Kinematics;
• Mechanical event simulation (MES).
• Analysis tools for process simulation for operations such as casting, molding, and
die press forming.
• Optimization of the product or process.

In general, there are three phases in any computer-aided engineering task:
• Pre-processing – defining the model and environmental factors to be applied to it.
(typically a finite element model, but facet, voxel and thin sheet methods are also
used)
• Analysis solver (usually performed on high powered computers)
• Post-processing of results (using visualization tools)
This cycle is iterated, often many times, either manually or with the use of commercial
optimization software.
Need for CAD, CAE & CAM :-
The usage of CAD CAE & CAM have changed the overlook of the industries
and developed healthy & standard competition , as could achieve target in lean
time and ultimately the product reaches market in estimated time with better
quality and consistency . In general view, it has lead to fast approach and
creative thinking.
ADVANTAGES:-
Cut off of the designing time
Cut off of the editing time
Cut off of the manufacturing time
High & controlled quality
Reduction of process cost.
Consistency
Maintenance of Universal accessing data

DRAW BACKS:-
❖ Requires skilled operators
❖ Initial setting & assumption consumes time
❖ Setting cost is more
❖ Over heads are high and
❖ Applicable if production is high

INTRODUCTION TO Chaff cutter
CHAFF CUTTER
A chaff cutter is a mechanical device used to cut the straw or hay into small
pieces so as to mix it together with other forage grass and fed to horses and cattle.
This improves the animal's digestion and prevents animals from rejecting any part
of their food. Chaff and operation until they were replaced by tractors in the 1940s.
Chaff cutters have developed gradually from the simple machines to commercial
standard machines that can be driven at various speeds so as to achieve various
sizes of chaff with respect to animal preference type. New chaff cutter machines
include portable tractor driven chaff cutters in which cutting of chaff is done in the
field and loaded in trolleys. The present green fodder cutting machine features a
single, only rod-shaped cut green fodder, green fodder cannot cut block. Whether
peasant family, tribunal or farms and sales markets are in urgent need of a new,
practical, functional and greener fodder cutter. The population of cattle in India in
1987 was 274million. For such kind of population, traditional human-powered
fodder cutting machines were used, but due to this, the efforts for running the
machine was physically demanding. And as per today's scenario, the population of
cattle is drastically increased. So to increase the productivity and reduce the
physical effort required for running the machine the motorized types of machinery
came into existence.

WHY WE PREFERD UNIGRAPHICS?
• The main advantages of UNIGRAPHICS that it is very user friendly software.
• From any different software we can import models and can be converted to
UNIGRAPHICS features.
• It has a powerful rendering option to make the object realistic.
• When it is impractical to get the desired shape/geometry in solid design (part
design), it can be easily developed in shape design module. As
UNIGRAPHICS is an interactive software so switching into different modules
can possible at the time of modeling.
• Developed to use in the aerospace, automotive, shipbuilding, and other
industries to design all type of rich &complex design.
• Dynamic view can be store to define different motion in kinematic.
• Bidirectional associativity between assay, modeling & drafting.
• Powerful sheet metal options, surface to sheet conversion & tool design.
• Notable automobile &aerospace industries using UNIGRAPHICS are Volvo,
Fiat, Renault, Toyota, Honda, Ford, , Hyundai, LN&T, TATA motors and
Mahindra ,ISRO ,HAL & ADA.

THE STAGE BY STAGE DEVELOPMENT OF CAD MODELS
In this era, the industries look for cost effectiveness and the man power efficiency
in any product development. This is possible only through the effective usage of
CAE/CAD/CAM software technology. This ensures the reduction in time as well the
manpower used for design and development of a product with improvement in
product quality.
This session deals with the explanation of CAD modeling of each part and the
functionality of those parts in the CHAFF CUTTER ASSEMBLY.
The flow of explanation of modeling of Chaff cutter is as follows:
1. Modeling of each part with the steps followed to generate the geometric
model and their function in the whole assembly.
2. Drafting & detailing of various parts of Chaff cutter assembly.
3. Detailing of each components are being presented.
Different parts of Chaff cutter:
• Flywheel
• Blades
• Main shaft
• Handle
• Worm
• Worm gear
• Shear plate
• Feeding tray
• Feeding roll

GROUP WORK ACTIVITIES
It is very important for an engineer to have a complete knowledge about
the task he is involved in for this, just having a theoretical; knowledge is
not enough. What is more important i.e. to do the work practically? For
this purpose working in a group make the task much easy and effective.
A group must consist of sincere, hardworking, dedicated, and intelligent
individuals.
Our group consists of eight members Er. Rahul Nath, Er. Lilesh Patel,
Er. Maniyar Mohammad Sohail, Rahul Kandi, Sushri Supravat Swain, Kshirod
Kumar Dehury, Srikanta Kumar Nayak, Rajendra Kumar Rath who have worked
very hard and have given their best effort in producing this product, a
project on DESIGNING OF CHAFF CUTTING MACHINE USING NX
Each one showed his active participation and was involved right from
preparing the format, collecting data on chaff cutter and its parts from various
sources, designing these parts and assembling them using UNIGRAPHICS,
producing the project report and presenting it.

CONCLUSION
While working on this project we came across details of both designing and manufacturing.
The designing of the CHAFF CUTTER, has enriched us with knowledge about model
designing, drafting, assembly in the CAD/CAM software’s UNIGRAPHICS. , which has
raised our skill and self-confidence regarding any such type of project in future.
Never the less the designing of this engine enriched is with the technique of operation of
different designing skills. The designing process helped us to gain experience through
designing related activities like designing in 3D views, study of various drawing sheets,
drafting and mechanisms.
And at last we learned how to face and tackle with the problems that arise during the course
of completion of the project.
