MACHINE-TOOLS
Machine-tools
are used to shape metals and other materials. The material to be shaped is
called the workpiece. Most machine-tools are now electrically driven.
Machine-tools with electrical drive are faster and more accurate than hand
tools: they were an important element in the development of mass-production
processes, as they allowed individual parts to be made in large numbers so as
to be interchangeable.
All
machine-tools have facilities for holding both the workpiece and the tool, and
for accurately controlling the movement of the cutting tool relative to the
workpiece. Most machining operations generate large amounts of heat, and use
cooling fluids (usually a mixture of water and oils) for cooling and
lubrication.
Machine-tools
usually work materials mechanically but other machining methods have been
developed lately. They include chemical machining, spark erosion to machine
very hard materials to any shape by means of a continuous high-voltage spark
(discharge) between an electrode and a workpiece.

ROBOTS
IN MANUFACTURING
Today most robots are used in manufacturing operations. The
applications of robots can be divided into three categories:1. material handling
2. processing operations
3. assembly and inspection.
Material-handling is the transfer of material
and loading and unloading of machines. Material-transfer applications require
the robot to move materials or work parts from one to another. Many of these
tasks are relatively simple: robots pick up parts from one conveyor
and place them on another. Other transfer operations are more complex, such as
placing parts in an arrangement that can be calculated by the
robot. Machine loading and unloading operations utilize a robot to
load and unload parts. This requires the robot to be equipped with a gripper
that can grasp parts. Usually the gripper must be designed
specifically for the particular part geometry.
In robotic
processing operations, the robot manipulates a tool to perform a process on the
work part. Examples of such applications include spot welding,
continuous arc welding and spray painting. Spot welding of automobile bodies is
one of the most common applications of industrial robots.
