PREFACE

Nowadays we are depending more on computers due to their speed in

data processing, visualization capabilities, data storing in documentation as

well as numerical calculations etc. They have become an integral part of one

daily life. They find applications in communication, entertainment,

accounting, and scientific research and in production industries.

In production industries, computers are used from designing,

controlling manufacturing operations, etc, increasing efficiency and

productivity. This particular field of application being called Precise

Engineering Cycle which is further classified into Computer Aided Designing

(CAD), Computer Aided Engineering (CAE) and Computer Aided

Manufacturing (CAM).

In CAD, the design capability is dependent on the flexibility of the

software, the hardware configuration as well as designers imagination and

experience. There are of many application packages which all particularly

strong in specific areas of CAD. But there are also ones that have good all-

round capabilities like Pro/ENGINEER, CATIA, Solid Works etc. For the

time being NX CAD has established itself as one of the most widely used, due

to its advanced modeling capabilities, production of complex assemblies &

easy user interface as well as stability of models and photo-realistic images.

ABOUT PRO-E

Pro/ENGINEER is 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. The application

runs on Microsoft Windows platform, and provides solid

modeling, assembly modelling and drafting, finite element

analysis, and NC and tooling functionality for mechanical

engineers. Versions for UNIX systems were discontinued with the

release of version 4.0

The Pro/ENGINEER name was changed

to Creo

Elements/Pro on October 28, 2010, coinciding with PTCs

announcement of Cero, a new design software application suite.

Creo Elements/Pro will be discontinued after version 2 in favour of

the Creo design suite.

Pro-e advanced assembly enhances the

productivity of distributed for design criteria management ,top-

down assembly design, and assembly process planning .benefit

include more flexible design, improved technical documentation

,and accurate fabrication instructions. it also used in sheet metal

design and real time rendering its advanced assembly with a host

of specialized functions make designing and managing of even the

most complex design much easier

Summary of capabilities

Like any software it is continually being developed to include new

functionality. The details below aim to outline the scope of

capabilities to give an overview rather than giving specific detailson the individual functionality of the product.

Creo Elements/Pro is a software application within the

CAID/CAD/CAM/CAE category, along with other similar

products currently on the market.

Creo Elements/Pro is a parametric, feature-based modeling

architecture incorporated into a single database philosophy with

advanced rule-based design capabilities. It provides in-depth

control of complex geometry, as exemplified by the trajpar

parameter. The capabilities of the product can be split into the

three main headings of Engineering Design, Analysis andManufacturing. This data is then documented in a standard 2D

production drawing or the 3D drawing standard ASME Y14.41-

2003.

Engineering Design

Creo Elements/Pro offers a range of tools to enable the generation

of a complete digital representation of the product being designed.

In addition to the general geometry tools there is also the ability to

generate geometry of other integrated design disciplines such as

industrial and standard pipe work and complete wiring definitions.

Tools are also available to support collaborative development.

A number of concept design tools that provide up-front Industrial

Design concepts can then be used in the downstream process of

engineering the product. These range from conceptual Industrial

design sketches, reverse engineering with point cloud data and

comprehensive free-form surface tools.

a square cube

Analysis

Creo Elements/Pro has numerous analysis tools available and

covers thermal, static, dynamic and fatigue finite element analysis

along with other tools all designed to help with the development of

the product. These tools include human factors, manufacturing

tolerance, mould flow and design optimization. The design

optimization can be used at a geometry level to obtain the optimum

design dimensions and in conjunction with the finite element

analysis.

Manufacturing

By using the fundamental abilities of the software with regards to

the single data source principle, it provides a rich set of tools in the

manufacturing environment in the form of tooling design and

simulated CNC machining and output.

Tooling options cover specialty tools for molding, die-casting and

progressive tooling design.

Pro-E helps in 2D Drafting, 3D modeling (Part modeling,

Surface modeling, Detailing, Sheet metal modeling) with minimum

time duration.With this we can easily do the parametric constraints

solving, editing any feature at any time and update the changes

without any difficulty.And with this we can create different views

of models in detailing without disturbing the assembley

ABOUT THE PROECT

PLUMMER BLOCK:

To ensure effective sealing, plummer blocks are available

with a variety of special sealing options and end covers. Benefits

include a facility for easy mounting and dismounting of pre-

assembled shafts.

Plummer block housings can be used with high-capacity sphericalroller bearings or self-aligning ball bearings. They are

manufactured from high-strength cast iron as standard but are also

available in cast steel or spheroidal graphite cast iron. The

housings have a re-lubrication facility and can be used with either

oil or grease lubrication.

Features

1.Split plummer block design allows for easy mounting and

dismounting of pre-assembled shafts.

2.Sealing options - NSK offers a range of sealing options

including oil seals, labyrinth seals, or heavy-duty taconite

seals.

3.

Case end covers are available.

4.Multi-relubrication points are provided to ensure

relubrication of the bearing depending on orientation.5.Housing are supplied with spacer rings in order to provide

axial location. Those can be omitted for "free end" axial

front.
