Slide 1

Dr. Osama Al-Habahbah Automation Chapter 1 Introduction

Slide 2

The economic realities of the modern world that affect manufacturing enterprises are: Globalization. International outsourcing. Local outsourcing. Contract manufacturing. Tend toward the service sector in developed economies. Quality expectations. Operational efficiency.

Slide 3

Globalization. More countries are be coming industrialized, such as China and India, due to their high population and low labor cost. Local outsourcing. International outsourcing. More parts and products are outsourced to companies outside the USA. Within the same country. Due to specialty of the suppliers, cheaper rate in smaller companies, lack of in hoes manufacturing capability

Slide 4

Contract manufacturing. The customer designs product while the supplier makes the product. Quality expectations. Tend toward the service sector in developed economies. Erosion of direct in manufacturing. perfect quality is expected Operational efficiency. used to offset the high labor cost

Slide 5

Some modern manufacturing technology that help to compete : AutomationMaterial handling technologiesManufacturing systemFlexible manufacturingQuality programsComputer Integrated Manufacturing (CIM)Lean production

Slide 6

Reduces labor cost, decreases production cycle time, and improves quality. Include transportation, storage, tracking. Production line, manufacturing cells. Helps to compete in the low-volume/hig-mix product categories.

Slide 7

Such as statistical quality control and six sigma. Includes (CAD) : Computer Aided Design,(CAM): Computer Aided Manufacturing, and integrating computer networks. Accomplish more with less resources increases productivity

Slide 8

It is a collection of people, equipment, and procedures to perform the manufacturing operation they are two categories Factory Equipment Layout Factory Equipment Layout The set of procedures used by the company to manage production,such as product design.

Slide 9

Facilities Manual work system Worker machine Automated Using unpowered hand too ; Using power equipment Automated facility branches out-to: Semi-automated machines and fully automated machines

Slide 10

Functions of Manufacturing support system Business function Product design Manufacturing planning Manufacturing planning control Communicating with customer Either provided by customer or in house if its proprietary Scheduling, Capacity, planning and process planning Shop floor control Inventory control Quality control Product progress Balancing too little and too much inventory Product quality meets standard

Slide 11

Examples include :Automated machine tool that process parts, Automated assembly, industrial robots, Automatic material handling storage, Automatic quality control (inspection).

Slide 12

Type of automated manufacturing system Fixed automationprogrammableflexible High initial investment, high production rate, inflexibility High investment, low production rate, flexibility Minimalchange High initial investment, high production rate, inflexibility

Slide 13

Computer Integrated Manufacturing (CIM) : Such as CAD / CAM

Slide 14

Increase labor productivity. Reduce labor cost. Mitigate the effect of labor shortages Eliminate routine tasks Improves safety Improves quality Reduce manufacturing lead time Accomplish processes that cant be done manual. To avoid the high cost of not automating (competition)

Slide 15

It is still needed. It can be preferred to automation in some cases :

Slide 16

1- Task is technologically or economically too difficult to automate.. 2- Short product life cycle. 3- Customized product. 4- Ups and downs in demand. 5- To reduce risk of products failure. 6- Lack of capital to invest in automation.

Slide 17

Equipment maintenance Plant management. Engineering project work Programming and computer operation

Slide 18

Stand for

Slide 19

1- Specialization of operations: Use of special-purpose equipment for greatest efficiency. 2- Combined operations: Perform more than one operation at a given machine. 3- Simultaneous operations: To reduce processing time. 4- Integration of operations: Linking work-stations together increasing output 5- Increased flexibility: Maximum utilization of equipment Use the same equipment for a variety of products.

Slide 20

6- Improved material handling and storage: reduce work in process and shorter manufacturing lead times. 7- On-line inspection: (of quality) reduce scrap and improves quality. 8- Process control and optimization: process time decrease,quality increase. 9- Plant operations control (of the factory) 10-Computer-integrated manufacturing CIM: ( Design Operations Business ) Computer Network

Slide 21

Moving from manual to automated. Phase 1Phase 2Phase 3 Manual production. Automated production single-station system. Automated integrated production multi-station system.

Slide 22

Shout product introduction time. Gradual automation. Lower risk at the start.
