Introduction to manufacturing automation and CIM (Computer Integrated Manufacturing)
Automation:
set of all measures aiming at replacing human work through machines (e.g. automation is applied science)
the technology used for this purpose (e.g. this company has an automation department)
replacement of human work through machines (e.g. the automatisation of the textile factory caused uproar of the workers)
replacement of conscious activity by reflexes (e.g. drill of the sailors allows the automatisation of ship handling)
The use of computers and machines instead of people to do a job

4. CIM history (Continued… )
CIM scope within the enterprises:
Marketing
Product Design
Planning
Purchase
Manufacturing Engineering
Factory Automation Hardware
Warehousing
Logistics and Supply Chain Management
Finance
Information Management
Marketing: The need for a product is identified by the marketing division. The
specifications of the product, the projection of manufacturing quantities and the
strategy for marketing the product are also decided by the marketing department.
Marketing also works out the manufacturing costs to assess the economic viability
of the product.
ii. Product Design: The design department of the company establishes the initial
database for production of a proposed product. In a CIM system this is
accomplished through activities such as geometric modeling and computer aided
design while considering the product requirements and concepts generated by
the creativity of the design engineer. Configuration management is an important
activity in many designs. Complex designs are usually carried out by several
teams working simultaneously, located often in different parts of the world. The
design process is constrained by the costs that will be incurred in actual production
and by the capabilities of the available production equipment and processes. The
design process creates the database required to manufacture the part.
iii. Planning: The planning department takes the database established by the
design department and enriches it with production data and information to
produce a plan for the production of the product. Planning involves several
subsystems dealing with materials, facility, process, tools, manpower, capacity,
scheduling, outsourcing, assembly, inspection, logistics etc. In a CIM system,
this planning process should be constrained by the production costs and by
the production equipment and process capability, in order to generate an
optimized plan.
iv. Purchase: The purchase departments is responsible for placing the purchase
orders and follow up, ensure quality in the production process of the vendor,
receive the items, arrange for inspection and supply the items to the stores or
arrange timely delivery depending on the production schedule for eventual supply
to manufacture and assembly.
v. Manufacturing Engineering: Manufacturing Engineering is the activity of carrying
out the production of the product, involving further enrichment of the database
with performance data and information about the production equipment and
processes. In CIM, this requires activities like CNC programming, simulation and
computer aided scheduling of the production activity. This should include online
dynamic scheduling and control based on the real time performance of the
equipment and processes to assure continuous production activity. Often, the
need to meet fluctuating market demand requires the manufacturing system
flexible and agile.
vi. Factory Automation Hardware: Factory automation equipment further enriches
the database with equipment and process data, resident either in the operator or
the equipment to carry out the production process. In CIM system this consists
of computer controlled process machinery such as CNC machine tools, flexible
manufacturing systems (FMS), Computer controlled robots, material handling
systems, computer controlled assembly systems, flexibly automated inspection
systems and so on.
vii. Warehousing: Warehousing is the function involving storage and retrieval of
raw materials, components, finished goods as well as shipment of items. In
today’s complex outsourcing scenario and the need for just-in-time supply of
components and subsystems, logistics and supply chain management assume
great importance.
viii. Finance: Finance deals with the resources pertaining to money. Planning
of investment, working capital, and cash flow control, realization of
receipts, accounting and allocation of funds are the major tasks of the
finance departments.
Information Management: Information Management is perhaps one of the crucial
tasks in CIM. This involves master production scheduling, database management,
communication, manufacturing systems integration and management information

7. Automation (21541), Session # 3
Introduction to manufacturing automation and CIM (Computer Integrated Manufacturing)
Computer Integrated Manufacturing (CIM) encompasses
The entire range of product development and manufacturing activities with all the functions being carried out
With the help of dedicated software packages.
The data required for various functions are passed from one application software to another in a seamless manner
CIM considers
All activities from the design of the product to customer support in an integrated way,

8. CIM Database management
The information required for manufacturing cover a wide range of disciplines and serving a multitude of inter-related yet vastly differing needs.
A database can be defined as a collection of data in a single location designed to be used by different programmers for a variety of applications.
A database is a collection of logically related data stored together in a set of files intended to serve one or more applications in an optimal fashion.
Database must also have a predetermined structure and organization suitable for access, interpretation, or processing either manually or automatically

9. CIM Database management
The CIM database comprises basically four classes of data:
Product Data: Data about parts to be manufactured. It includes text and geometry data.
Manufacturing Data: The information as to how the parts are to be manufactured is available in production data.
Operational Data: Closely related to manufacturing data but describes the things specific to production, such as lot size, schedule, assembly sequence, qualification scheme.
Resource Data: This is closely related to operational data but describes the resources involved in operations, such as materials, machines, human resources and money

10. CIM Database management
Varied tasks one might expect to accomplish in a CIM environment:
Designing assemblies and performing tolerance analysis on those assemblies.
Preparing production drawings of assemblies, individual parts, tooling, fixtures and other manufacturing facilities.
Preparing part lists and bill of materials (BOM).
Preparing process plans for individual part manufacture and assembly.
Programming CNC machines for processing complete parts (CAM).
Designing work cells and programming the movement of components in those cells using work handling devices like robots, conveyors, AGV’s/ RGV’s.
Preparing inspection programs including programs for CNC machines.

11. Make your own CIM database !!
To understand the necessities of a CIM data base:
Groups with 5-6 students will be established
Each group starts the essential activities for forming a CIM database in the class theoretically
The implementation of theoretical activities will be conducted during the weeks in manufacturing laboratory
The implementation results will form the groups CIM databases during the course
