2. ABSTRACT
• Digital manufacturing is the use of an integrated, computer-based system comprised of simulation,
three-dimensional (3D) visualization, analytics and various collaboration tools to create product
and manufacturing process definitions simultaneously.
• The transition to digital manufacturing has become more popular with the rise in the quantity and
quality of computer systems in manufacturing plants.
• As more automated tools have become used in manufacturing plants it has become necessary to model,
simulate, and analyze all of the machines, tooling, and input materials in order to optimize the manufacturing
process.

5. MODELING SOFTWARE
• This helps in giving a real shape to any problem given and puts everything into perspective. This
also helps in analyzing the model in a variety of ways using the next set of software I am going to
discuss. In addition, with the advent of Rapid Prototyping, models designed properly can be directly
printed, giving an instant physical existence to your brainchild. Good hold on this category of
software is a huge plus point.
• CATIA (Computer Aided Three-dimensional Interactive
Application)
• Solid Works
• Pro-E
• AUTO-CAD ect,

6. ANALYSIS AND SIMULATION
• After the design, the next step is to analyze the design putting in a number of constraints, boundary
conditions and situations and test the design according to the physical demands it needs to fulfill.
Features like Static and Dynamic analysis, Thermal analysis etc. can be easily and very accurately done
with these highly useful and sophisticated software available.
• ANSYS
• COMSOL
• Hyper Mesh etc,

7. TECHNOLOGIES
• FMS, (flexible manufacturing system)
• ASRS, automated storage and retrieval system
• AGV, automated guided vehicle
• Robotics
• Automated conveyance systems etc,

8. FLEXIBLE MANUFACTURING SYSTEM
• A flexible manufacturing system (FMS) is a manufacturing system in which there is some amount of
flexibility that allows the system to react in case of changes, whether predicted or unpredicted. This
flexibility is generally considered to fall into two categories, which both contain numerous subcategories
• The first category, machine flexibility, covers the system's ability to be changed to produce new product
types, and ability to change the order of operations executed on a part
• The second category is called routing flexibility, which consists of the ability to use multiple machines to
perform the same operation on a part, as well as the system's ability to absorb large-scale changes, such
as in volume, capacity, or capability.

9. AUTOMATED STORAGE AND RETRIEVAL SYSTEM
An automated storage and retrieval system (ASRS or AS/RS) consists of a variety of computer-controlled
systems for automatically placing and retrieving loads from defined storage locations.] Automated storage
and retrieval systems (AS/RS) are typically used in applications where:
• There is a very high volume of loads being moved into and out of storage
• Storage density is important because of space constraints
• No value is added in this process (no processing, only storage and transport)
• Accuracy is critical because of potential expensive damages to the load

11. MACHINES IN DIGITAL MANUFACTURING
• Water jet cutting
• Laser beam cutting
• CNC lathe
• CNC milling
• Programmed robots etc,

12. ADVANTAGES
• Optimization of a parts manufacturing process. This can be done by modifying or creating procedures
within a virtual and controlled environment. By doing this the use of new robotic or automated systems
can be tested in the manufacturing procedure before being physically implemented.
• Digital manufacturing allows for the whole manufacturing process to be created virtually before it is
implemented physically. This enables designers to see the results of their process before investing time
and money into creating the physical plant.
• The effects caused by changing the machines or tooling processes can be seen in real-time. This allows
for analysis information to be taken for any individual part at any desired point during the
manufacturing process.

13. CONCLUSION
• From the above method the digital manufacturing method is more efficient than the others.
• The digital manufacturing method will give that more quality and quantity of productions.
• It will reducing that production cost of the products hence that product price reduced it attracts the
customers and it gives that more profits to industries.
