Abstract:
This experiment was conducted to identify the lathe machine and its
functionality and identify the axes of the lather machine.
Introduction:
A lathe is made up of multiple parts that function together to achieve the
desired objective of removing
Abstract
In this report the two categories of tools are explained. Hand tools and power tools. Hand tools
use the manual labor of the person operating the tool to function. While power tools require
electricity to function. Also the process of manufacturi
Abstract
The students were given the task of manufacturing a part from a wooding block
using the milling machine. The milling machine is a tool that is designed to
machine metal, wood and other solid materials. It uses rotary cutters to remove

Some of the important properties of solid materials
depend on geometrical atomic arrangements, and
also the interactions that exist among constituent
atoms or molecules.
This chapter considers several fundamental and
important concepts namely:

With the categories of engineering materials firmly
established, we can now begin characterizing these
materials.
We will begin with atomic-scale structure, which for most
engineering materials is crystalline; that is, the atoms of

In Chapter 4, we looked at a wide variety of atomic-scale
structures characteristic of important engineering
materials, but with perfectly repetitive crystalline structures.

Stress and strain: What are they and why are they used instead of
load and deformation?
Elastic behavior: When loads are small, how much deformation
occurs? What materials deform least?
Plastic behavior: At what point does permanent
Materials of all types are often heat treated to improve
their properties.
The phenomena that occur during a heat treatment almost
always involve atomic diffusion.
Often an enhancement of diffusion rate is desired; on
