light.

radiation.

9. Main Components of LBM
• Laser cutter frame: The mechanical part of the
laser cutter is responsible for the movement in the
X, Y, and Z-axes, including the cutting work
platform. The stability of the machine tool is
crucial for fibre laser cutting machines, as it
directly impacts the cutting precision.
• Laser generator: A device that produces a laser
light source is known as a laser generator. The laser
generator is the main power source of laser
equipment, similar to the engine in a car and is the
most expensive component of fiber laser cutting
machines.
10. • Lenses: The laser lens is the most commonly used component in fiber laser cutting equipment.
Various optical devices contain laser lenses, each serving a different purpose, such as full-reflection
lenses, semi-reflection lenses, and focusing lenses.
• CNC Control System: The control system is the primary operating system of the fiber laser
cutting machine, which mainly controls the movements of the X, Y, and Z axes and regulates the
output power of the laser. Its quality determines the stability of the machine’s operating
performance. The precision and cutting effect can be effectively improved through accurate control
of the software.
• Regulated power supply: The connection between the laser generator, the laser cutter, and the
power supply system serves mainly to prevent interference from the external power network.
• Laser Cutting head: The cutting head is the laser output device of a fiber laser cutting machine,
consisting of a nozzle, a focusing lens, and a focus tracking system. The cutting head drive device,
which consists of a servo motor, screw rod, or gear, moves the cutting head along the Z-axis as
programmed.
11. Working of LBM
• In this process LASER is focused on work
piece by optical lens.
• Used light energy from a laser to remove
material by vaporization.
• Energy is concentrated optically.
• Thermal and Optical energy is used in this
process.
• Light beam pulsed so that the released
energy results in an impulse against the
work surface, producing melting and
evaporation.
12. WATER JET MACHINING
Introduction
• When the water stream strikes a workpiece surface, the erosive force of water removes the material
rapidly
• The water, in this case, acts like a saw and cuts a narrow groove in the workpiece material.
• This method uses high-pressure water to cut materials with precision.
• First, the machine's manufacturer designs the machine for any specific task.
• After that, the manufacturer makes sure all required materials are accessible and cuts them with
water jets.

14. MAIN COMPONENTS OF WATER JET MACHINE
• Water Reservoir: A water reservoir is used to store water which is to be used for the machining
process. The reservoir is generally situated somewhat above the whole setup. This is to ensure a
continuous and uninterrupted flow of water.
• Hydraulic Pump: A hydraulic pump is used to transfer water from the reservoir and supply it further
at a desired pressure. The hydraulic pump is provided with a pressure gauge to measure the pressure
of water being passed.
• Hydraulic Intensifier: Hydraulic intensifier is the main part of a water jet machining setup. This is
responsible for increasing the pressure of water from 5 bars to 3000-5000 bars. Hydraulic intensifiers
are a set of three concentric cylinders that use the weight of inlet water to increase the pressure of
outlet water.
15. • Accumulator: An accumulator is a tank that stores high-pressure water used for machining. It
supplies water whenever there is a pressure drop and more high-pressure water is needed. The
accumulator is an important element as it helps in the smooth running of the water jet machining
process.
• Nozzle: The nozzle is the part of a water jet machining setup that converts the pressure energy of
water to kinetic energy. A nozzle has a decreasing area of cross-section and hence can increase the
kinetic energy of water. The nozzle is made of ruby or diamond so that no cutting action should take
place at the nozzle end.
• Drain System: The drain system collects the water after machining and sends it back to the reservoir
tank. The drain system is connected to a pump which helps in the transfer of water to the supply tank.
16. Working
• When very high-pressure water is passing through the
convergent nozzle the pressure energy is converted into
velocity energy or kinetic energy.
• Therefore the water is coming out from the nozzle at a very
high velocity which is obtained to be 200 to 400 m per
second.
• When this high-velocity water Jet is impinging onto the
workpiece, the continuous impact load is acting onto it.
• In this, the Material Removal Rate(MRR) is directly proportional to the velocity of the water jet and this velocity
depends on the distance between the nozzle tip and workpiece.
• In this, no tool is used and the only nozzle is used and to withstand higher pressures.
• The nozzle is made by using Tungsten Carbide.
17. VERTICAL MILLING MACHINE
Introduction
• VMC typically stands for 'Vertical Machining
Center" which is also a CNC.
• The cutting head in this milling machine is
vertical and is a particular type of milling
machine where the spindle runs in a vertical
axis known as the "z" axis.
• They are typically enclosed and most often
used for cutting metal

19. COMPONENTS OF VMC
• Rotating Spindle: The Spindle, which is perpendicular to the
working surface or table, can hold a variety of cutting tools (or
mills as they are sometimes called). The spindle cartridge is
mounted in a housing that moved up and down—this direction of
motion is called the Z-Axis.
• Table: The Table is a platform on which to mount workpieces—
either directly or through a variety of fixtures like milled
aluminium plates or hard clamping vices. The table has a motion of
left and right, which we call the X-Axis, and front to back, which is
called the Y-Axis. These two axes of motion, coupled with the Z-
Axis, allow for virtually unlimited contouring across the planes of
motion.
20. • Automatic Tool Changers: Automatic Tool Changers are commonly seen in industrial-grade VMCs. It
helps you bridge the delay in changing tools and allows faster processing.
• Coolant System: To keep parts and cutters cool and lubricated, most VMCs employ some sort of
recirculating coolant system; which is usually a mix of soluble oil and water but can be a variety of
other liquids as well.
• CNC controller: CNC controller is one of the major components of a VMC machine. It is the central
processing unit that controls the transmissions of each of the axes. The controller allows you to connect
your machine to a computer. You can even operate it offline on VMCs with a connected pendant.
21. Working of VMC
• Vertical milling operations involves point to point and straight cut motion control systems.
• CAD (computer-aided design) operation is the first step towards making a successful part on a CNC
machine.
• The design is then converted to code using CAM (computer-aided manufacturing) software.
• In the control stage, we use the generated G-code file to control the machine. Control software that
seamlessly interfaces with the CNC controller on VMC is used for this process.
• One should set up the machine tools before running the machine. The setup procedure includes setting
up the table, the cutting tool, and other necessary components.
• The next step is to set up the operation parameters for milling. These include depth of cut, chip load,
feed rate, spindle speed and cutting speed.

25. GEOMETRIC DIMENSIONING & TOLERANCING
• Geometric dimensioning and tolerancing (GD&T) is a system of symbols used on engineering
drawings to communicate information from the designer to the manufacturer through engineering
drawings
• GD&T is an international language used to describe a part accurately.
• It comprises of symbols, rules and definitions for defining a geometry of mechanical part.
• It has many benefits like uniformity in drawings, Better designs, No assumptions, large tolerances
• It is used especially in the manufacturing sector for dimensioning and Tolerancing
• The standard used was ASME Y14.5M-1994 and now, ASME Y14.5-2009 is used
