Collaborative Cross functional Team approach will bring Innovative and Low cost Quality Products into LIFE
Design for x : Design for Manufacturing,Design for Assembly Naseel Ibnu Azeez
Concurrent engineering is a contemporary approach to DFSS. DFX techniques are part of detail design and are ideal approaches to improve life-cycle cost, quality, increased design flexibility, and increased efficiency and productivity using the concurrent design concepts (Maskell 1991). Benefits are usually pinned as competitiveness measures, improved decision-making, and enhanced operational efficiency. The letter “X” in DFX is made up of two parts: life-cycle processes x and performance measure
A case study on concurrent engineering in the development of automotive components using DFMA/DFX approach.
DFMA- DESIGN FOR MANUFACTURING AND ASSEMBLY.
“Design for manufacture” means the design for ease of manufacture for the collection of parts that will form the product after assembly.

Final project report on grocery store management system..pdfKamal Acharya
In today’s fast-changing business environment, it’s extremely important to be able to respond to client needs in the most effective and timely manner. If your customers wish to see your business online and have instant access to your products or services.
Online Grocery Store is an e-commerce website, which retails various grocery products. This project allows viewing various products available enables registered users to purchase desired products instantly using Paytm, UPI payment processor (Instant Pay) and also can place order by using Cash on Delivery (Pay Later) option. This project provides an easy access to Administrators and Managers to view orders placed using Pay Later and Instant Pay options.
In order to develop an e-commerce website, a number of Technologies must be studied and understood. These include multi-tiered architecture, server and client-side scripting techniques, implementation technologies, programming language (such as PHP, HTML, CSS, JavaScript) and MySQL relational databases. This is a project with the objective to develop a basic website where a consumer is provided with a shopping cart website and also to know about the technologies used to develop such a website.
This document will discuss each of the underlying technologies to create and implement an e- commerce website.
CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

2. Purpose Statement
To provide an overview of Design for
Manufacturing and Assembly (DFMA)
techniques, which are used to minimize
product cost through design and process
improvements.
3. Design for Manufacturing
Definition: DFM is the method of design for ease of
manufacturing of the collection of parts that will form the product
after assembly.
‘Optimization of the
manufacturing
process…’
DFA is a tool used to select the most cost effective material and
process to be used in the production in the early stages of product
design.
4. Major DFM objectives
1) Estimate the mfg. costs
2) Reduce the costs of components
3) Reduce the costs of assembly
4) Reduce the costs of supporting production
5) Consider the impact of DFM decisions on other
factors.
5. Design for Assembly
Definition: DFA is the method of design of the
product for ease of assembly.
‘…Optimization
of the part/system
assembly’
DFA is a tool used to assist the design teams in the design of
products that will transition to productions at a minimum cost,
focusing on the number of parts, handling and ease of assembly.
6. Differences
Design for Assembly (DFA)
• concerned only with reducing product assembly
cost
▫ minimizes number of assembly operations
▫ individual parts tend to be more complex in design
Design for Manufacturing (DFM)
• concerned with reducing overall part production
cost
▫ minimizes complexity of manufacturing operations
▫ uses common datum features and primary axes
7. Similarities
• Both DFM and DFA seek to reduce material,
overhead, and labor cost.
• They both shorten the product development cycle time.
• Both DFM and DFA seek to utilize standards to reduce
cost
8. Terminology
Design for Manufacturing (DFM) and Design for
Assembly (DFA) are now commonly referred to as a
single methodology, Design for Manufacturing and
Assembly (DFMA) .
11. Design for Manufacturing (DFM) and design for
assembly (DFA) are the integration of product
design and process planning into one common
activity.
The goal is to design a product that is easily and
economically manufactured.
12. The heart of any design for manufacturing system is a
group of design principles or guidelines that are
structured to help the designer reduce the cost and
difficulty of manufacturing an item. The following is a
listing of these rules
13. Reduce the total number of parts
The reduction of the number of parts in a product is probably the best
opportunity for reducing manufacturing costs. Less parts implies
less purchases, inventory, handling, processing time, development
time, equipment, engineering time, assembly difficulty, service
inspection, testing
14. Develop a modular design
The use of modules in product design simplifies
manufacturing activities such as inspection, testing,
assembly, purchasing, redesign, maintenance, service
15. Use of standard components
Standard components are less expensive than custom-
made items. The high availability of these components
reduces product lead times.
16. Design parts to be multi-functional
Multi-functional parts reduce the total number of parts in
a design, thus, obtaining the benefits given in rule 1.
Some examples are a part to act as both an electric
conductor and as a structural member, or as a heat
dissipating element and as a structural member.
17. Design parts for multi-use
In a manufacturing firm, different products can share
parts that have been designed for multi-use. These parts
can have the same or different functions when used in
different products.
In order to do this, it is necessary to identify the parts that
are suitable for multi-use. For example, all the parts used
in the firm (purchased or made) can be sorted into two
groups: the first containing all the parts that are used
commonly in all products.
18. Design for ease of fabrication
Select the optimum combination between the material and
fabrication process to minimize the overall
manufacturing cost. In general, final operations such as
painting, polishing, finish machining, etc. should be
avoided. Excessive tolerance, surface-finish requirement,
and so on are commonly found problems that result in
higher than necessary production cost.
19. Avoid separate fasteners
The use of fasteners increases the cost of manufacturing a
part due to the handling and feeding operations that
have to be performed. Besides the high cost of the
equipment required for them, these operations are not
100% successful, so they contribute to reducing the
overall manufacturing efficiency. In general, fasteners
should be avoided and replaced, for example, by using
tabs or snap fits.
22. Minimize assembly directions
All parts should be assembled from one direction. If
possible, the best way to add parts is from above, in a
vertical direction, parallel to the gravitational direction
(downward).
In this way, the effects of gravity help the assembly
process, contrary to having to compensate for its effect
when other directions are chosen.
