INTRODUCTION TO MANUFACTURING SYSTEMS BME

Manufacturing System Definition:

A collection of integrated equipment & human resources, whose function is to perform one or more processing and/or assembly operations on a starting raw materials, part, or set of parts.

 Components of a Manufacturing System

1.       Production Machines

2.       Material Handling System

3.       Computer Control System

4.       Human Resources

A Classification Scheme for Manufacturing Systems

1.       Type of Operations Performed

2.       Numbers of Workstations

3.       System Layout

4.       Automation & Manning Levels

Manufacturing  Equipment includes:

1.       Production machines and tools

2.       Material handling and

3.       work positioning devices  

4.       Computer systems

5.       Human resources: are required either full-time or periodically to keep the system running.

A manufacturing system consists of several components:

1. Production machines plus tools, fixtures & other

related hardware

2. Material handling system

3. Computer systems to coordinate and/or control the

above components

4. Human workers.

Machines can be classified as:

Manually operated: control or supervised by a human worker.

i.e. lathes, milling machines, drill presses

Semi-automated: performs a portion of the work cycle under some from of program control, and human worker tends to the machine for the remainder of the cycle, by loading and unloading it or performing.

 i.e. CNC lathe controlled.

 Fully automated.: operates for extended periods of time with no human attention.

i.e. injection molding machines.

Material Handling System

The following material handling functions must be provided:

1. Loading work units at each station

2. Positioning the work units at each station

3. Unloading work units at each station

4. Transportation of work units between station in multi-station manufacturing systems
