CNC Machine using Arduino

CNC Machine using Arduino:

Machining is needed to manufacture almost everything that we use today. All the components are manufactured by various machines, but CNC machine in particular is the most widely used one among all. Through this mechanical mini project you will build a fully functional 3 axis CNC machine that can perform the actions like drilling, milling, tooling etc. You will be using an Arduino board to control the operations of the machine and carry out specific set of machining actions. Doing this mechanical mini project will help you understand the machining process in depth and develop a better understanding on the entire process.

What is CNC MACHINE ?
CNC stands for Computerized Numerical Control. CNC Machining is about automating the machine tool operations for more precision and ease in manufacturing. In this project you will build a fully functional 3 axis CNC machine using Arduino which can perform manufacturing operations like drilling, milling and cutting. The tool can be operated with the help of G Codes and Arduino interfacing.

By building this project, you will practically work with stepper motors, Arduino board, G Codes, CNC calibration and programming.

Design & Fabrication of Motorized Scissor Jack

A Scissor jack is mechanical equipment used to lift up heavy loads. The power screw mechanism included in a scissor jack is design to lower the amount of force needed to lift the heavy loads. The operation of a scissor jack starts by using a z shaped crank that is mounted to a small hole on the mechanism. After rotating the crank, the screw jack rotates and acts like a gear mechanism. The lifting section consists of arms. The turning of screw operates the arms in such a way that it lifts up very gently. Now the arm rotates very gently and force needed to lift the vehicle is divided into parts and user can lift very heavy objects with comparatively very less force. Also the weight of the load is not enough to push the scissor down, since it would require very large force. Thus it allows us to life heavy loads like cars by just using human strength, also the system is further improved by making it motorized so user does not need to operate it manually but just press a button for lifting and lowering it.

Electromagnetic Braking System

INTRODUCTION:

Electromagnetic braking means applying brakes using electronic and magnetic power. Here we use the principle of electromagnetism to achieve friction less braking. This tends to increase the life span and reliability of brakes since no friction leads to less wearing out of brakes. Also it requires less maintenance and oiling. This is an upcoming technological replacement for traditional braking systems. The main purpose behind the proposed use of these brakes in vehicles is that it is frictionless. This leads to a sizably less maintenance cost due to no friction and no oiling. Also traditional braking systems are prone to slipping while this one is guaranteed to apply brakes to the vehicle. So without friction or need of lubrication this technology is a preferred replacement for traditional braking. Also it is quite smaller in size compared to the traditional braking systems.
To make electromagnetic brakes work, a magnetic flux when passed in a direction perpendicular to the rotating direction of the wheel, we see eddy current flowing in a direction opposite to the rotation of the wheel. This creates an opposing force to the wheel rotation and in turn slows down the wheel. Thus we achieve electromagnetic braking as a better braking system for future automobiles.

Automated 5 D Robotic Arm Mechanism

Robotic arms are widely used in industries, manufacturing lines and other industrial purposes. Robotic arms are used to implement complex industrial automation functionality which only humans can achieve. These functionalities include picking up a part and placing it horizontally into another machine or picking parts and placing it in packing boxes and more. So here we propose the design and fabrication of a fully automated robotic arm that can automate various industrial tasks. Our system consists of an assembly of mounts and parts designed to hold motors in place in order to achieve desired movement. Also it consists of a gripper designed with gear teeth in order to achieve gripping function as per motor rotation. The system consists of 5 motors needed to achieve the desired movement. A circuit board provided with it allows controlling the movement of the circuit according to the button pressed. This mechanism helps in understanding the working and control flow of industrial robotic arms design and fabrication processes.

Regenerative Braking System

We are slowly reaching the age of electric vehicles. The major issue behind the mass use of electric vehicles is the battery charging time and lack of charging stations. So here we propose a regenerative breaking system. This system allows a vehicle to generate energy each time brakes are applied. The stronger the brakes, the more power is generated. We use friction lining arrangement in a brake drum. As a drum rotates the friction lining does not tough the drum As soon as brakes are applied, the friction lining touches the drum from inside and moves the motors connected to lining in same direction, thus generating electricity using motors as dynamo. Thus this system allows for charging car battery each time brakes are applied, thus providing a regenerative braking system. It moves us another step ahead towards a pollution free transportation system.

 

Components :

  • Brake drum (which is attached to the wheels)
  • Friction lining
  • 2x Generator motors
  • Linking mechanism
  • Supporting Frame
  • Joints
  • Screws & Bolts

 

Advantages:

  • Reduces fuel consumption
  • Increases overall efficiency of vehicle by 33%
  • Cut down pollution related to electricity generation
  • Increases lifespan of friction braking system
