This document summarizes a seminar on design for manufacturing and assembly processes. It discusses how design for manufacturing (DFM) aims to minimize production costs and time to market while maintaining quality. DFM strategies include reducing part counts and selecting appropriate manufacturing methods. Design for assembly (DFA) specifically focuses on minimizing assembly costs by reducing assembly operations and making individual parts easier to assemble. The document provides guidelines for DFA, such as reducing part counts, standardizing parts, simplifying assembly, and designing self-locating and self-fastening parts to streamline the assembly process.
A major cost factor in the production of and component or assembly is its assembly. This section looks at some commonly used techniques which a designer can employ to ensure that assembly is cost effective and efficient. This is then linked to the use of jigs and fixtures for this purpose.
CAD is one part of the whole Digital Product Development (DPD) activity within the Product Lifecycle Management (PLM) processes, and as such is used together with other tools, which are either integrated modules or stand-alone products, such as:
• Computer-aided engineering (CAE) and Finite element analysis (FEA)
• Computer-aided manufacturing (CAM) including instructions to Computer Numerical Control (CNC) machines
• Photo realistic rendering and Motion Simulation.
• Document management and revision control using Product Data Management (PDM).

Design for Assembly (DFA) is a vital component of concurrent engineering – the multidisciplinary approach to product development. You might think it strange to begin by thinking about the assembly before you have designed all the components, but you can often eliminate many parts at the conceptual stage, and save yourself a lot of trouble.

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
Design for Manufacturability power point presentation,
This PPT improve the study of design for manufacturability.
DFM is utilized in many industries ranging from industrial products, microelectronics, scientific instruments, and the aerospace industry
To design a product that can be easily, efficiently, and cost effectively be manufactured
To reduce overall cost of a product – warranty, engineering changes, factory floor space, unnecessary parts, and service
Using modules simplifies the manufacturing process
Allows for the use of standard components
Allows for tests to be conducted prior to the product being assembled
Using parts for the same or different operations multiple times in a product
Reduces the number of parts that need to be developed
Less machines - Less usage of factory floor space
Optimal assembly of a product occurs in one direction
Preferred direction is from above using gravity to assist in the manufacturing process
Errors in insertion due to positioning and dimensional variability cause damage to parts and to machinery
Use tapers, chamfers and moderate radii to ease insertion
Example – utilization of a rigid base and tactile and visual sensors in assembly
Positioning, orienting, and fixing a part are time consuming and costly
Use external guiding features to orient the part
Ideally the part should be placed one time
The process of designing the product and the manufacturing process simultaneously to increase the efficiency and reduce the time to launch a product

2. • Design for manufacturing (DFM) is design
based on minimizing the cost of
production and/or time to market for a
product, while maintaining an
appropriate level of quality. The strategy
in DFM involves minimizing the number
of parts in a product and selecting the
appropriate manufacturing process.
Design for Manufacturing
3. 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
4. DESIGN FOR ASSEMBLY
“A PROCESS FOR IMPROVING PRODUCT
DESIGN FOR EASY LOW-COST ASSEMBLY,
FOCUSING ON FUNCTIONALITY AND ON
ASSEMBLABLITY CONCURRENTLY.”
-VINCENT CHAN &FILIPPO.
Design of components taking into account how they will
be assembled together to ensure that assembly costs are
minimized.
DFA is the method of design of the product for ease of
assembly
5. Manual
Most flexible & Most expensive
Skill of workers effects assembly times
Hard Automation
Custom tooling – only make one product
Soft Automation
Robots
Types of Assembly
6. Concept Design
Design for
Assembly
Design for
Manufacturing
Detailed Design
Optimize Design for
Part Count and
Assembly
Optimize Design for
Production Readiness
Sequence of Analysis
7. Product Information: functional requirements
Functional analysis
Identify parts that can be standardized
Determine part count efficiencies
Step 2
Step 1
Analyze data for new design
Step 3
Identify handling (grasp & orientation) opportunitiesStep 4
Identify insertion (locate & secure) opportunitiesStep 5
Step 6 Identify opportunities to reduce secondary operations
Identify quality (mistake proofing) opportunities
Benchmark when possible
Determine your practical part count
Step 7
DFA Process
8. 1. Reduce number of parts
2. Reduce number of different parts - Standardize parts
3. Simplification of assembly
4. Reduction number of processes
5. Less fasteners especially screws & bolts
6. Design parts with self-locating features
7. Design parts with self-fastening features.
8. Minimize reorientation of parts during assembly
9. Ensure access & visibility
10. Easy part handling
11. Assemble from top
12. Reduce locating/alignment operations – manual/time
consuming
DFA Guidelines
10. The following change could easily be made:
the powder metal bushings are unnecessary because the part can be
machined from an alternative material with the right frictional characteristics,
such as Nylon
The following are difficult to justify:
separate stand-offs
end plate
cover
the six screws
We started with this.
18. Asymmetric Part Symmetry of a part
makes assembly easier
Symmetry eliminates reorientation
1. Critical orientation – obvious – see & fit
2. Non-critical orientation – fit in any direction
Question: What do we do first…..Design for Manufacturing or Design for Assembly?
Answer: We do DFA first, then DFM. That way you’re not wasting your time optimizing the manufacturing processes on component parts that you might end up eliminating from the assembly.
