Abstract – Industry is always move fast to produce variety
Main aim of project work is design simulate and development of pneumatic sequential circuit A+B+B-C+C-Aconfiguration. Which is widely used for sheet metal operation like clamping, bending and forming etc.
of products. Sheet metal have wide application in manufacturing industry like automobile, aerospace industry and medical industry. In industry sheet metal operations are carried out by manually or with the use of fluid power. Hydraulic fluid power systems are not suitable for small and medium scale industry. Compressed air is the one of the easiest sources of energy. Pneumatic fluid power system has wide range of feasibility in point of view of industrial applications. Objective of the project work is to Simulate and develop a pneumatic system consist multiple actuators used to perform sheet metal operations clamping, bending and forming.
2 LITERATURE REVIEW 1. Developing Multiple-Actuator Pneumatic Circuits Using the Karnaugh Maps Designing PLC Controlled
Author: AlZahraa N. Fawzi, Maher Y. Salloom Aim of this work is to develop multiple-actuator pneumatic circuits and reduce start-up times by merging various operational sequences into a single process. The Karnaugh maps is a technique for reducing logical equations or transforming truth tables into logic circuits. The method allows for circuit control using a programmable controller (PLC). The study focuses use Karnaugh Maps to develop a pneumatic control system in difficult cases with three different control sequences for five cylinders. Simulation software for pneumatic/electro-pneumatic circuits is utilized to apply the technique (Automation Studio and Fluid Sim).
Key Words: Pneumatics, Simulation, Hydraulic fluid power, Sheet metal.
1.INTRODUCTION Today highly competitive industry needs developing new technologies. Automation plays key role in industry to save material, labour and improving delivering quality product. Sheet metal operations are one of the fundamental operations in metal working. Sheet metal operations are usually carried out by manually or fluid power. In small and medium industry hydra ulic machines are not feasible. Pneumatic power system gained importance in the field of automation. Pneumatics is the branch of technology that deals with use of compressed air to produce motion. In pneumatics air is using as the working fluid. The word pneumatics derived from the Greek pneuma meaning breath or air. Pneumatics is the application of compressed or pressurized air to power machine to control or regulate them. Pneumatics also defined as branch of fluid power that deals with generation, transmission and control of power using pressurized air. An air compressor converts mechanical energy of primover in to pressure energy of compressed air. Pneumatic system consist compressor, FRL unit, direction control valve and actuators. Actuators are either reciprocating actuators or rotating actuators. Actuators convert pneumatic energy into mechanical energy. Simulation always play a vital role in manufacturing industry. Effective pneumatic system requires effective working simulation. Fluid SIM is a software tool for creating simulating hydraulic, pneumatic, electro-hydraulic, electropneumatic digital electronic system.

2. Design and Development of Pneumatic Sheet Metal Cutting Machine Author: Sudarshan. U, Sunil Kumar K, Darshan S. R, Kushal. P, Varshith. N This paper presents an efficient and cost-effective method for shearing sheet metal using a pneumatic actuation system that can be applied in small and medium-scale industries. This work provides a safe and effective way to cut sheet metal with minimal maintenance costs. The cutting thickness range can be increased by arranging a high-pressure compressor and installing more hardened blades.
