About Mechanical Engineering.

Introduction.

Meaning Of Mechanical :It is Combination of four words - me+chan+i+cal = Mechanical

-it is branch of a science which is deals with laws & principles of a mechanism and it's application in engineering problems

-Mechanical engineering is a discipline of engineering that applies the principles of physics and materials science for analysis, design, manufacturing, and maintenance of mechanical systems. It is the branch of engineering that involves the production and usage of heat and mechanical power for the design, production, and operation of machines and tools.[1] It is one of the oldest and broadest engineering disciplines.

Different Types of patterns used in Casting Process

Different types of patterns: the types of pattern used depends upon the design of casting, complexity of shape, the number of casting required moulding process, surface finish and accuracy. The common types of patterns are: 1) Single piece pattern 2) Split piece pattern 3) Loose piece pattern 4) Gated pattern 5) Match pattern 6) Sweep pattern 7) Cope and drag pattern 8) Skeleton pattern 9) Shell pattern 10) Follow board pattern Figure 1: Single piece, Split, Match-plate, Cope and Drag Pattern Single piece pattern: This is the simplest type of pattern, exactly like the desired casting. For making a mould, the pattern is accommodated either in cope or drag. Used for producing a few large castings, for example, stuffing box of steam engine. Split pattern: These patterns are split along the parting plane (which may be flat or irregular surface) to facilitate the extraction of the patternout of the mould before the pouring operation.
