Sundaram
Fasteners a Group company
world renowned automobile
accessories manufacturing
TVS Group company with
a 18 Billion US Dollar
turnover mainly concentrating
on Design and Manufacturing
of Special purpose fasteners,
as a pioneer company started
from the year 1966 SFL
is planned to diversify
its plan to invest its
time more towards Value
Product Development (VPD).
One of the fore most steps
in VPD is to automate
its Standard Product Development
(SPD). This project involves
- optimizing the design
process by reducing the
time on Standard Product
Development and focusing
on Valued Product Development.
The Design Process
The
typical design cycles
are as follow
Present
Workflow
Creation of Product
& Process Drawings
Process Sequence drawing
for various stages
Selection of Machine
for the process
Generation of Tool Inserts
drawings
Generation of Tool
Schedule
Pains
in the existed design process
Manual
calculation of
Volume of the Screw
or Bolt
Volume of each stage
process Along with
Tool schedule generation
Grade related parameters
entry
Thread related parameters
entry
Repeated entry of same
parameter value in different
places
Proposed
Workflow
A simple user interface
is available where the
user has to feed the
changing parameters
of the Screw or Bolt
The Software will
first check whether
the same bolt or screw
size is available
in the Database if
that is available
it will reproduce
the old or it will
create the new one
Tool
schedule
Option to generate
Various Tool Drawings
for different Machines
at right click, So
that designers will
concentrate only on
VPD
Utilization of part
numbers which was
generated previously
Even a Person from
Marketing Department
can enter the values
and get the drawings
Built in intelligence
in Database to ensure
that correct part
numbers appear in
Tool Schedule
Parameters which appear
in different places
will get update all
the places like Grade
related parameters
etc.
Reference to manuals
or other parameters
is eliminated completely
Ultimate
Goal of Project Ultimate
Goal of Project
To save
90% MAN HOURS in SPD.
To achieve
90 % Increased productivity
in D & D for SPD,
80 % decrease in time
to start manufacturing.
90 % Time save error
creation
Success

Objective
of the project
To provide accurate
and error free jigs
and fixtures design
in shortest time possible
while minimizing trials
and corrections
To simplify the design
process in the project
planning department
Improve quality of
design by reducing
the errors
Reusability of existing
design to reduce the
design cycle time
of jig and fixtures
To improve overall
efficiency of the
design process
To integrate the costing
within the CAD environment
To manage CAD data
efficiently and securely
Project
