Machine Design and Factory Automation
The Process of Machine Design
Machine design, as it is applied to Factory Automation, has occupied most of my
professional career.
My exposure to the design of machines, started, at High School (in the U.K.), on
a basic drawing board, complete with 't" square and plastic set square!
Over the years, we have progressed through the beautifully engineered and
manufactured drafting tables to today's 3D CAD systems.
My first 2D Cad system, used a 386 computer and it was very difficult to learn a
whole new concept of designing, but eventually, we succeeded.
Today, 3D CAD, is the accepted format.
I still use 2D CAD, for the initial layout and design of the system, but once
the concept is finalized, we then switch to 3D.
During the process of machine design, it is assumed, the Request For Quotation, the Budget and the Quotation, are all
available, to the designer.

DESIGN PROCEDURE.
- Once the concept is finalized, then the design process can begin.
- Download software, of all the standard parts, that are that are used. Go to the
various vendor's websites and select the correct software for the program you
are using.
- Obtain software of the customer's part (s).
- Start your design, at the part-this could be a holding fixture, or maybe a
gripper finger, for a robot or a pick and place unit. Work your way outwards,
from
this point.
- DEFINE THE PROBLEM!
I have found, over the years, that if the problem is
defined accurately enough-then a solution, can be obvious!
- THE DESIGN CRITERIA-
a. Can the part be manufactured economically?
b. Can the part be assembled and dis-assembled?
c. Does the part possess adequate strength, for the application?
d. Ensure the design satisfies all the points in the R.F.Q. and P.O., giving
acceptable life and is within the Budget.
Do not be surprised if the design procedure has to be repeated.
This happens usually more
than once, before a design meets all of the criteria for an acceptable design.
Unfortunately there is no substitute for experience!
