Automatic control has become an important and integral part of modern
manufacturing and industrial processes .Automatic control provide means for attaining
optimal performance of dynamic systems, improve the quality and lower the cost of
production, expand the production rate, relive the drudgery of many routine, repetitive
manual operations, etc.. In this paper it has been designed a control system which
controlled the operation of punch machine .As shown in Fig. (1) this system consists of:
(1) the programmable logic controller (PLC) which is used to control time and regulate
the sequence. (2) The Hydraulic system receives and implements the logical commands
of PLC. (3) Electrical interfacing circuits which are very important to compromise in the
stages of system. In order to avoid mistakes of direct design and implementation in the
industrial and production processes and what follows from high material cost, therefore
Automation Studio Software has been used to design the hydraulic system according to
the required giving's by using Simulation software before the machine is fabricated, also
it is distinguished in the simplicity of using ,have a very good specification in design and
the ability of exposing the parts of the system in one screen and show the connection
between them ,this led to have expected programmable results.
