MANUFACTURING ENGINEERING

-
Introduction
Manufacturing engineering may be defined as designing production process for a product. Although there is a large difference of opinion on exactly what is included in the design of a production process, almost all people would generally agree with the above definition. Production or manufacturing engineering includes all considerations pertaining to the process of production. This include such functions as the following:
  1. Evaluating the manufacturability of the product
  2. Selecting processes and setting process parameters such as cutting tool material, size, and shape; cutting speed; dept of cut; and so on.
  3. Designing work-holding devices (jigs and fixtures) to secure and control the position of the workpiece during manufacture.
  4. Estimating the cost of manufacturing the part
  5. Assuring the quality of the part produced
 The rate of technological change in manufacture engineering is phenomenal likely to increase. "Keeping up" is already a very difficult TASK. The future is likely to see a progressive manufacturing engineer spending 15 to 25% of his or her time simply studying new technology. Computerization, integration of controls, robotizations, and coordination of manufacturing activities are areas where change is likely to be most rapid. It is important to note, however, that in spite of the new technology, the basics still apply. For example, the most sophisticated computer controlled machine center still performs its functions according to basic metal cutting theory. It is vital for the manufacturing engineer to know and understand the basics of manufacturing engineering.

Product-Production Design Interaction
Product design requires that a person develop and evaluate the ability of the part to perform its intended function. Part characteristic such as

CODE SWITCHING, CODE MIXING, AND INTERFERENCE

-
CODE SWITCHING, CODE MIXING, AND INTERFERENCE           Code switching is the term used to refer to the situation where two or more codes (languages) are used in the same conversation or utterances. There are several factors influencing code switching, such as the solidarity with the listeners, the choice of the topic, and perceived social and cultural distance. People also switch when there is a new participant, solidarity relationship and status. Other switching is caused by the choice of the topic and affective functions.           Code mixing suggest the speaker is mixing up code indiscriminately or perhaps because of incompetence. It occurs when conversations use both language together in the course of a single utterance. Interference is the use of formal elements of one code within the context of another. It can occur at phonological, morphological, lexical or syntactical levels. ...
