Chapter 3 Manufacturing Systems,Unit 1 Introduction to Manufacturing Systems Unit 2 Advanced Manufacturing Systems Unit 3 Manufacturing Support Systems,Unit 1 Introduction to Manufacturing Systems,The Definition of Manufacturing System Components of Manufacturing System Classifications of Manufacturing Systems,Definition of Manufacturing System,We define a manufacturing system to be a collection of integrated equipment and human resources, whose function is to perform one or more processing and/or assembly operations on a starting raw material, part, or set of parts.,Definition of Manufacturing System,The integrated equipment includes production machines and tools, material handling and work positioning devices, and computer systems. Human resources are required either full time or periodically to keep the system running.,Components of a Manufacturing System,Production machines Material transport Systems Computer Control System Human Resources,Production machines,Manually operated production machines Semi-automated production machines Fully automated production machines,Material transport System,Three functions: (1)Loading-involves moving the work units into the production machine or processing equipment from a source inside the station. (2)Positioning-provides for the part to be in a known location and orientation relative to the workhead or tooling that performs the operation.,Material transport System,(3)Unloading- When the production operation has been completed, the work unit must be unloaded, that is, removed from the production machine and either placed in a container at the workstation or prepared for transport to the next workstation in the processing sequence.,Computer Control System,Communicate instructions to workers Download part programs to computer-controlled machines Material handling system control Schedule production Failure diagnosis Safety monitoring Quality control Operations management,Human Resources,Human perform some or all of the value-added work that is accomplished on the parts or products.,Classification of Manufacturing System,Type 1: Single Stations Type 2: Multi-Station Cells Type 3: Production Lines,Unit 2 Advanced Manufacturing Systems,Group Technology (GT) Flexible Manufacturing Systems (FMS) Computer Integrated Manufacturing Systems (CIMS) Lean Production (LP) Agile Manufacturing (AM) E-Manufacturing,Group Technology (GT),Two Major Tasks: (1)Identifying the part families (2)Rearranging production machines into machine cells,Benefits of Group Technology,Promotes standardization Material handling is reduced Process planning and production scheduling are simplified Setup times are reduced Work-in-process is reduced Worker satisfaction improves Higher quality work is accomplished,Flexible Manufacturing Systems (FMS),Content of FMS: (1) Process equipment (2) Material handling equipment (3) A communication system (4) A computer control system,Advantages of FMS,(1)Increased productivity (2)Shorter preparation time for new products (3)Reduction of inventory parts in the plant (4)Saving of labor cost (5)Improves product quality (6)Attracting skilled people to manufacturing (7)Improved operators safety,Computer Integrated Manufacturing Systems (CIMS),Activities of CIMS: (1)Identifying a need for a product (2)Designing a product to meet the needs (3)Obtaining the raw materials needed to produce the product (4)Applying appropriate processes to transform the raw materials into finished products (5)Transporting products to the market (6)Maintaining the products to endure proper performance in the field,Benefits of CIMS,(1)Product quality increases (2)Lead times are reduced (3)Direct labor costs are reduced (4)Product development times are reduced (5)Inventories are reduced (6)Overall productivity increases (7)Design quality increased,Lean Production (LP),Ten Rules of LP: (1)Eliminate waste; (2)Minimize inventory; (3) Maximize flow; (4) Pull production from customer demand; (5) Meet customer requirements;,Lean Production (LP),Ten Rules of LP: (6) Do it right the first time; (7) Empower workers; (8) Design for rapid changeover; (9) Partner with suppliers; (10) Create a culture of continuous improvement.,Agile Manufacturing (AM),AM is a New Manufacturing Strategy AM is a Production Mode of the 21st Century,E-Manufacturing,What is E-Manufacturing? What is the Future of E-Manufacturing?,Unit 3 Manufacturing Support Systems,CAD (Computer-Aided Design) CAM (Computer-Aided Manufacturing) CAPP (Computer-Aided Process Planning) CAE (Computer-Aided Engineering),Chapter 4 Service Systems,Unit 1 Introduction to Service Systems Unit 2 Service Quality,Unit 1 Introduction to Service Systems,Definition of Service Classifications of Service Characteristics of Service Operations,Unit 2 Service Quality,Dimensions of Service Quality Measuring Service Quality,Dimensions of Service Quality,Reliability Responsi
