1. TITLE OF THE PROJECT;
FABRICATION OF AUTOMATIC DRILLING AND
REAMING ATTACHMENT
OBJECTIVE;
· To develop industrial automation and assist with CIM environment.
To promote the unmanned industry.
· To promote the unmanned industry.
Project Background;
In the present global rationalization and competitive world most of
the industries set up unmanned industry in order to eliminate labour cost
and to increase productivity.
SYNOPSIS;
The main aim of this project is to acquire practical Knowledge in the field of
automation using PLC. . In this project “FABRICATION OF AUTOMATIC
DRILLING AND REAMING ATTACHMENT ” the job is feeded, drilled and
reamed automatically.

2. Initially the job is loaded manually. The job , drilling, reaming feed
movements done by the separate DC motors through the lead screw and nut
mechanism .These motors are controlled by the PLC .
These movements are stopped at particular position using magnetic
sensors which sends the signal to the input of PLC .The entire operation is
done automatically by using PLC, the components are manufactured with less
time and the production rates are increased.
