Introduction of Manufacturing Process
DDJ 3003 : MANUFACTURING PROCESSES
CHAPTER 1 : INTRODUCTION
MANUFACTURING - derived from Latin
It is converting raw materials into Products using machinery and operations through a well-organized plan
It has the function of adding value.
Discrete or Continuous products
1. DEFINITION OF MANUFACTURING
1. The application of physical and chemical processes to alter the geometry, properties, and/or appearance of a given starting material to make parts or products.
2. The transformation of materials into items of greater value by means of one or more processing and/or assembly operations.
3. The making of goods and articles by hand or machinery, often on a large scale and with a division of labor.
2. FIVE (5) MAIN TYPES OF MANUFACTURING PROCESSES
1. Metal casting -melting and cooling of metal, pouring a fluid into a shape and then freeze it. (ex : Plastic)
2. Deformation of material ; squash into the shape we want.
Particulate processes (powder metallurgy)
3. Material removal - cut into a desired shape.
4. Permanent joining metal - parts together as added value to the products.
5. Parts dimensioning & surface coating
3. TERM OF SPECIFICATION
1. A detailed, exact statement of particulars, especially a statement prescribing materials, dimensiond, and quality of work for something to be built, installed, or manufactured.
2. A single item or article that has been specified.
3. TERM OF STANDARDISATION
1. Standardization - the condition in which a standard has been successfully establishe; “standardization of nuts and bolts had saved industry millions of dollars”.
2. Standardize cause to conform to standard or nom evaluate by comparing with a standard
4. IMPORTANCE OF SPECIFICATION, STANDARDIZATION, TOLERANCE, LIMIT & FIT IN MANUFACTURE
SPECIFICATION :
1. Improved efficiency in specifying
2. Expanded decision-making capability
3. Stabilized office practice and make markets work better
4. Easier updating of specification data
5.
