Machine-tools- ameasure of
Man’s progress
2.
The variety and combinationsof machine-tools today are unlimited
3.
Some of them are verysmall and can be
mounted on a work
bench but others are so
large that we have to
construct special
buildings to house them
4.
There are some basicoperations at any
workshop
5.
They are turning,drilling, threading,
etc
6.
The main machine-tool of such aworkshop is the multipurpose lathe
7.
What is a lathe?8.
It is a power-driven machine withspecial tools which can cut or form
metal parts
9.
The metal that cuts anothermetal must be very hard and so
tools should be made of very hard
steel alloys
10.
The tool itself is very small incomparison with the mechanism
that is to direct it
11.
Technological progress improvesaccuracy o f machine-tools
12.
Today's equipment can produceparts with very high accuracy
13.
One can find a number of machinetools that can measure and inspecttheir
production themselves - machinetools that are to handle the parts
mechanically and
automatically
14.
Such machines can hold the partswhich are to be measured and are
able to
indicate precise measurements
themselves
15.
A great many of such "clever"machines can be found today in
our industry.
Automation is one of the main
factors of engineering progress
16.
Automation is one of the mainfactors of engineering progress
17.
Flexible production lines form thebasis for automated workshops
18.
The main principle of such aflexible line is the fact that it can be
switched over
from one product to another, which
has a similar structure but a
different outline,
almost instantaneously
19.
It is equally efficient in conditionsto both mass and small-batch
production
and will serve to increase the
productivity
