Plastic: Composition, Classification, Moulding, Properties, Uses and Biodegradable Plastic

Plastic: Composition, Classification, Moulding, Properties, Uses and Biodegradable Plastic! Brief History of Plastics: The plastic is one of the recent engineering material which has appeared in the market all over the world. Some varieties of naturally occurring thermo-plastics were known to Egyptians and Romans who extracted and used these plastics for various purposes. A number of scientists carried out experiments [...]

Engineering Materials: Properties and Classification

In this article we will discuss about the properties and classification of engineering materials used in industries. Properties of Materials: Material selection should be based mainly upon the properties of material. The designer must decide the properties required of a material for a part under design and then weight the properties of candidate material. There are literally hundreds of properties [...]

List of Metals and their Alloys | Material Engineering

Here is a list of metals and their alloys. An alloy is a substance that has metallic properties and is composed of two or more chemical elements, of which, at least one is a metal. Basically, alloying is done to give strength to metal as the alloying element occupies interstitial space, which create compressive and tensile strength depending on the [...]

Scheduling Procedures for Production | Production Management

There are several scheduling procedures in use. We take the following scheduling example: 1. Shortest Processing Time (SPT) Procedure: A schedule obtained by sequencing jobs for production in non-decreasing order of processing times is called a shortest processing time (SPT) schedule. This schedule minimizes mean flow time F̅. In addition, the SPT rule also minimizes mean lateness and means waiting [...]

Computer Controlled Machine Tools: 2 Types | Industrial Engineering

Two types of configurations of computer controlled machine tools are commonly found (i) where a dedicated small microcomputer is used for control of one machine tool (referred to as computer numerical control or (CNC), and (ii) where a large computer controls a number of separate NC machine tools, (referred to as direct numerical control or DNC). Type # 1. CNC [...]

Power Flow from Motor to Spindle: With Diagram | Lathe | Industrial Engineering

The power flows from the motor in the base to the cone-pulley by means of a belt. The belt can be adjusted to three or four positions to vary the spindle-speed. Fig. 12.15 gives the idea as to how the different spindle speeds can be obtained. Various spindle speeds can be obtained by shifting the belt on different steps of [...]
