OBJECTIVE : TO DESIGN A COMPOUND

DIE FOR BLANKING AND PUNCHING

USING AXIOMATIC DESIGN APPROACH

AXIOMATIC DESIGN

Axiomatic design is a system

design methodology using matrix methods to

systematically analyze the transformation of customer

needs into functional requirements, design parameters,

and process variables. Specifically, functional

requirements (FRs) are related to design parameters

(DPs) .

The Design principles used here are the Design Axioms

governing the analysis and decision making process in

developing high quality product or system designs.

Two axioms used in design are :

1. The Independence Axiom : Maintain the

Independence of the Functional Requirement .

2. The Information Axiom : Minimize the information

content of the design.

Functional requirement

Functional requirements (FRs) are a minimum set of

independent requirements that completely characterize the

functional needs of the design solution in the functional

domain.

Some Functional Requirement of a Compound Die Design

are :

• Minimise Burrs.

• Minimise Rollover.

• Economy of material

Design parameters :-

Design Parameters are the elements of the design solution

in the physical domain that are chosen to satisfy the

specified Functional Requirements.

Some of the design parameters in compound die are

1. Clearance in punch and die

2. Material selections.

COMPOUND DIE

A die designed to simultaneously perform more

than one operation in each stroke of the press.

Compound die is more economical in mass

production as compared to single operation dies.

Application : Automobile Industry, Aerospace

Industry .

COMPONENTS OF COMPOUND DIE

COMPOUND DIE HAVE VARIOUS CRUCIAL

COMPONENTS SUCH AS :

1. DIE BLOCK

2. PUNCH PLATE

3. BLANK PUNCH

4. PIERCE PUNCH

5. STRIPPER PLATE

6. BLANKING DIE

7. PIERCING DIE

1.Clearance

2.Material used

3.Cutting force for punching

4.Cutting force for blanking

5.Economy of material

6.Design of spring used in stripper

OPERATIONS PERFORMED ON COMPOUND DIE

BLANKING : BLANKING IS THE OPERATION OF

CUTTING A FLAT SHAPE FROM SHEET METAL.

THE ARTICLE PUNCHED OUT IS CALLED BLANK

AND IT IS THE REQUIRED PRODUCT OF

OPERATION .

PUNCHING : IT IS A CUTTING OPERATION BY

WHICH SHAPED HOLES ARE MADE IN SHEET

METAL . PUNCHING IS SIMILAR TO BLANKING

EXCEPT THAT IN PUNCHING THE HOLE IS THE

DESIRED PRODUCT.

WORK PLAN

7th Semester

• Literature Review

• Determining Customer requirements.

• Determination of Functional Requirements and

corresponding Design Parameters.

• Implementation of Design Parameters in Designing the Die.

8th Semester

• Design of the prototype in Computer Software.

• Design is based upon the design parameters from previous

semester work.
