Introduction
A drilling machine, called a drill press, is used to cut holes into or through metal, wood, or other materials. Drilling machines may be used to perform other operations.They can perform counter sinking, boring, counter boring,spot facing, reaming, and tapping. In this arrangement we presented a concept of control for automated micro-drilling, “cluster” type, in which several miniature robots, piezoelectric trained, are used to transport the piece of work to hold and to permit the micro-borer introduction.

What Is Drilling Machine.. ?
• Drilling machine can actually be defined as a power operated machine tool which consists of a drill in its spindle that rotate and when moved in a linear motion against on to the workpiece can produce circular hole on it.
• A drilling machine normally consists of a part like base to support the machine, a work table to support the workpiece, drilling head which revolves the cutting tools and a radial arm. This machine employes a gearing mechanism to drill a hole into the workpiece.

Hardware Components
1. Microcontroller ATMEGA8 :
The Atmel ATmega8 is a powerful microcontroller that provides a highly-flexible and cost-effective solution to many embedded control applications . The ATmega8 is supported with a full suite of program and system development tools, including C compilers, macro assemblers, program simulators, and evaluation kits. It has 23 Programmable I/O Lines.

2. L293D Motor Driver IC:
L293D is a dual h-bridge motor driver, so with one IC we can interface two DC motors which can be controlled in both clockwise and anticlockwise direction.L293D has output current of 600mA and peak output current of 1.2A per channel.

3. Brushed DC Motor : Brushed DC motor types have some performance advantages
over direct-current, excited, synchronous types, and have become predominant in fractional horsepower applications. They are smaller, lighter, more efficient and reliable than other electric machines. In this research, one DC motor is used for drill. The motor selected for MSR is the 12V DC motor.

Types of Drilling Process
1. Reaming :
A reamer enters the workpiece axially and enlarges an existing hole to the diameter of the tool.
Page 12
2. Countersinking : A countersink tool enlarges the top portion of an existing hole
to a cone-shaped opening.
Countersinking is performed after drilling to provide space for the head of a fastener, such as a screw, to sit flush with the workpiece surface.

3. Counterboring :
A counterbore tool enlarges the top portion of an existing hole to the diameter of the tool.
Counterboring is often performed after drilling to provide space for the head of a fastener, such as a bolt, to sit flush with the workpiece surface.

Advantages
Intelligent PCB drilling machine can be used continuously 24 hours a day,365 days in a year and need to switch on occasional maintenance.
Less skilled/trained people can intelligent PCB drilling machine unlike manual lathes/milling machine ,etc which need skilled engineers.
Modern design software allow the designer to simulate the manufacture of his/her idea .There is no need to make a prototype.

Application Of Robotics Drilling System
Drilling machines may be used to perform other operations like it can perform countersinking, boring, counterboring, spot facing, reaming, and tapping.
• Drilling machine also used for small scale circuit designing industries.
• Drilling machines may be used to perform other operations like it can perform countersinking, boring, counterboring, spot facing, reaming, and tapping.

Future Scope
• The drilling head assembly with slide can be replaced by other equipment like to weling gun /gas welding equipment thus making it a multifunctional machine.
• The drilling machine can be made more advanced automated by using advanced motors ,software technologies ,controllers, etc.
• The introduction of dedicated automation equipment improved productivity, reduced defect rate, and reduced quality dispersion.

Conclusion The prototype developed is a technical platform that enables
the development of some accuracy studies of micro positioning with a large impact on the design of new command and control hardware units.
The introduction of dedicated automation equipment greatly reduced the potential for safety accidents from tasks.
The introduction of dedicated automation equipment improved productivity, reduced defect rate, and reduced quality dispersion.
