Over the past 150 years, as technology has developed in many different directions, the exact definition of the word “machining” has evolved. Initially, for the most part, people worked by hand, utilizing techniques like hand-forging and filing metal, as well as, carving wood.

But, in this era, there is strong competition and a broad spectrum of complexity in product demand. The industry has had to implement new machining optimization procedures due to material, size, complex design, and finish factors. These tactics involve implementing new technology, improving process flexibility and efficiency, and even altering the organizational structure.”

Modern production has substituted outdated machinery such as hammers, chisels,s and shaping machines with computer numerical control (CNC) systems. If you are an industrial person, a product creator with new ideas, who turns public demand into reality then you know precision technology isn’t just an option – it’s a necessity.

Now, buckle up your seats, as this blog is the ticket for you on a rollercoaster ride, in which we will uncover a detail on what is CNC machining, how CNC Machining is different from other machining techniques, and how it works. Do you think it going to be boring? Exactly No! Don’t worry! It will not be a historical lecture instead you will learn interesting information on how CNC Machining is ruling in every product manufacturing industry.

So, Are you ready for this ride?  Let’s delve deep into it.

1. Introduction to CNC Machining

Computerized Numerical Control is referred to as CNC. It’s a computerized control manufacturing process where production equipment moves according to preprogrammed software and code. The use of computers for design is known as computer-aided design or CAD. In CNC, CAD/CAM integration is used to design and manufacture the product.

G-code is a unique kind of code used to operate CNC machine equipment. To make a product with the necessary shape and size, components are automatically programmed to work following the sequence of events established by the user.

2. How Was CNC Developed?  

The first “data systems” for machines were imagined by John T. Parsons, vice president of the Parsons Corporation’s Aircraft Division one of the top producers of mechanical parts at the time. He got in touch with MIT’s Servomechanisms Laboratory Professor Gordon S. Brown in the spring of 1949. NCs began to evolve in a modern manner in 1948 or 1949.

The United States Air Force was an important stakeholder in this advancement since it wanted machines for the aircraft industry that could produce complicated parts more quickly, cheaply, and accurately than with traditional methods. Therefore, the Air Force funded research into the viability of automated contour-cutting machines. The MIT Servomechanisms Laboratory and the John Parsons Company led the development of the first milling machine experimental models, which were tested in a few companies by 1951.

3. How Is CNC Machining Operated?

The computer transfers the data from the input and output, evaluates it on the device or in memory, examines the sensor readings, and then comes back to the computer to assess the readings from the sensors and the input till the lowest error rate is achieved, leading to the greatest level of precision and high excellence. In CNC machining the MCU works as the heart of CNC machine. The basic layout of the working principle is shown below.

The CNC machining process contains multiple essential components that operate together seamlessly. The CNC system’s MCU (Machine Control Unit) receives the part program first. The MCU processes all of the data. Then, using the prepared program, it creates exact motion orders and sends them to the drive system.

Components of CNC system

Here are the following components of a CNC machine.

(i) Input Devices:

These units are in charge of feeding the CNC machine’s part design. Three types of device input are frequently utilized: computers connected via RS-232-C protocol, magnetic tape readers, and punch tape readers.

(ii) Machine Control Unit (MCU)

The CNC machine’s Machine Control Unit (MCU) is its brain; it controls every aspect of the machine. It can read and decode coded instructions, produce axis motion commands through linear, circular, and helical interpolation, feed these instructions to amplifier circuits that operate the axis processes, get feedback signals indicating the velocity and position for each drive axis, and perform auxiliary control functions like coolant or spindle on or off and tool changes, among other things.

(iii) Machine Tool:

Machine tools use some kind of tool to perform machining or cutting. The CNC machine tool has a spindle for speed and position control and a slide table. Z-axis control is applied to the spindle, and X and Y-axis control is applied to the machine table.

(iv) Driving System:

 Drive motors, ball lead screws, and amplifier circuits make up the driving system. The amplifier circuits receive inputs from the MCU for each axis, such as position and speed, and then augment or boost the control signals to activate the drive motors. The machine table is positioned by the actuated drive motors rotating the ball lead screw in turn.

(v) Feedback System:

 Transducers are used in this system to function as sensors and measurement tools. It constantly keeps track of the cutting tool’s position and speed at all times. After receiving signals from these transducers, the MCU creates control signals to fix speed and position errors by comparing the reference and feedback signals.

(vi) Display Unit:

 CNC machine projects, commands, and other relevant data are shown on a monitor that serves as a display unit.

4. What Are the Types of CNC Machines?

CNC machines are efficient because of their exceptional precision when handling various kinds of materials. Digital control machines have demonstrated their effectiveness in handling thick materials and their ability to quickly penetrate them, in contrast to other types of machinery. Several kinds of CNC machines have been developed as a result of this versatility: CNC machines can be categorized based on the work function of CNC machines, and the number of axes.

a)CNC Router

In addition to cutting sheet metal, plastic, and wood, CNC routers also provide three-dimensional axes for manufacturing complex and large-scale items. furthermore used to cut various materials along a route. The CNC router’s form is shown in the Figure below.

b) Water Jet Cutting

This cold-cut method, which is used in CNC machines and does not contaminate the environment, cuts over any sort of soft or hard material, including ceramics, glass, and metal, by pumping water through the material. The water jet cutting form is shown in the figure below.

c) 3D printers

One of the most recent techniques for manufacturing is three-dimensional printing, which involves creating a product on a computer, having it printed using a 3D printer, and then fabricating it in a realistic and tactile manner. The 3D printers are shaped like stacks of material, and the printing process involves building layers of material on top of each other to create the desired product.

d) Milling Machine

This kind of CNC machine cuts various materials from produced materials by using rotary cutters. The form of the milling machine is represented by a Figure when it was operating by hand.

e) Plasma Cutters

This kind of CNC machine uses plasma to split steel and other materials, and plasma scissors are used for cutting the material.

Electric Discharge Machine

To cut conductive materials, one uses Electrical Discharge Machines or EDMs. An electrical arc is produced in EDM when a cutting head close to the material emits electrical pulses. The arc here creates a cut after melting and removing the material at the necessary location.

Laser Cutting

A laser beam is utilized for cutting materials. There is no restriction on what materials can be cut using laser cutting—unlike plasma cutting. By modifying the laser’s specifications, beams of light can penetrate any material.

Other CNC Machines  Based  on their Axis of Motion

Here is the other list of CNC machines categorized based on the axis of motion. There are several CNC machines, each with unique uses and characteristics. The most fundamental kind is the 3-axis CNC milling machine, which has three dimensions of linear movement: X, Y, and Z. In contrast, the 4-axis CNC milling machine allows for the cutting of four sides of a product with just one fixture setup by adding a rotational axis (A axis) to the X, Y, and Z movements. The 5-axis CNC milling machine, which has two extra rotating axes (B and C axes), is the most sophisticated kind. The most complex and costly form of CNC milling machine is the 7-axis model, which offers more features for quicker production and more seamless operations.

5. How CNC Machining Process?

Turning raw resources into finished product is the process of manufacturing. Generally speaking, manufacturing is an intricate procedure involving a wide range of tools and techniques. This kind of automated machining technique uses computer numerical control technology to shape an object or a part. There are the following number of steps to consider while doing CNC machining.

    A. Pre-Processing/product design

The initial stage in the manufacturing process is to create a design for the product. The mechanical design of a product is important before it is manufactured because it establishes the tolerances that the product must fulfill to be regarded as appropriate.  There are following software is used for this purpose.

        1. Designing the part in CAD software

 CAD software is used to make sketches of the geometric shapes that need to be made in all dimensions and, if needed, transform them from two dimensions to three. The design of an item is essential before it is manufactured because it establishes the product tolerances for manufacturing. Once the design is complete, it is exported to code languages so that CAM can read it.

        2. Creating toolpaths in CAM software

Mathematical models/GCODE representing two-D or three-D geometrical models are further transferred to CAM software on a computer. There are three possible formats for this mathematical model: wireframe, surface, or solid.  Creating a toolpath involves choosing the machining approach, cutting equipment, and machining settings are all part of this process. Below is the process diagram of the CAM software.

    B. Setup

The setup part involves material, tool selection, and choosing work-holding devices and fixtures. It is very crucial in ensuring the CNC machining process’s accuracy and quality. Therefore, several factors need to be considered before running a CNC program.

        1. Loading materials and tools

It includes choosing the right material and tool for the CNC machining. There is a vast range of materials available that apply to CNC machining. Choose any material that fulfills your requirements in strength, quality, and durability, and most importantly it should be cost-effective as well. For CNC machines, the tools need to be highly interchangeable, very stiff, and quickly changing to minimize non-cutting time.

Tool Selection and Operation Setup

In this section, we choose the appropriate cutting tool according to workpiece selection such as diamond tools are selected for hard materials. Tools are used to cut/ design a material in the desired shape. Three primary material types are utilized for cutting tools: ceramic, tungsten carbide, and high-speed steel.  It is crucial to provide careful consideration to the selection and use of CNC machine tooling, namely tool holders.  We set up the tool in-CNC machine properly to avoid its wearability. In the operation setup, the input is used to control system parameters such as spindle speed, feed rate, tolerance, and coolant on/off.

        2. Securing the workpiece on the machine

Fixture and work holding devices are used to ensure the workpiece sample isn’t misplaced from its original position so that all pieces produced using the fixture will remain replaceable and compatible. This process avoids the uncertain breakage of the sample, and the tool during the process.

    C. Machining Operations

The CNC machine tool equipment carries out operations by attaining linear sliding and turning movements. When the user commands the system to move the cutting tool along the x and y axes, the system will react accordingly.

        1. Running the CNC program

Initially, Conduct a dry run (devoid of any cutting material) to confirm that the tool’s actions, trajectories, and sequences are accurate. Make sure there are no unanticipated motions or crashes.  The cutting tool’s axis or cutting tool reaches the desired position following the program. Every control system is designed to keep the device from automating until the return to zero is carried out.

        2. Monitoring and adjusting parameters

 Make a proper adjustment of required parameters during CNC machining like feed rate, and spindle speed. Make sure to monitor the initial CNC cut carefully to avoid any damage. If anything unexpected failure happens it can be managed carefully.  Continuous monitor the CNC machining process to verify the dimensions and tolerance.

    D. Post-Processing

Post-processing includes ensuring the final quality inspection and removing excess material or deburring and finishing the material. After the machining process check the product quality, surface finish, and required dimensions. If there is any kind of roughness found on the product surface deburr it. Use surface treatments such as anodizing, coating, or polishing the product if needed.

6. Surface Finish

Following CNC machining, surface finish is a crucial factor that influences the machined parts’ functioning, appearance, and performance. Surface finishes are used to modify the look, the degree of hardness, resistance to chemical attack, and texture of components that are processed.  Here are the most common surface finishes.

1. Polishing

It employs buffing tools and abrasive substances to create a mirror-like surface that improves appearance and lowers friction.

2. Bead Blasting

It involves blasting the surface with fine abrasive particles to create a uniform, matte texture. It is the perfect method for getting rid of tool marks and producing a consistent appearance

3. Anodizing

It deposits a thin layer of oxide coating on aluminum parts to improve chemical and corrosion resistance.

4. Plating

 To improve durability against wear, electrical conductivity, and corrosion resistance, a very thin film of metal (such as nickel or chrome) is applied to the surface.

5. Powder coating

This method creates a consistent, superior surface by applying an electrostatically charged powder and heating it to cure, resulting in a long-lasting, beautiful finish.

7. What Are The Most Common Machining Processes?

The machining process involves employing machines that can perform tasks such as lathes, milling machines, scrap machines, and others to carry out facing, roughing, finishing, cutting, slashing forms, and other operations to create workpieces following the intended design.  Here are some machining processes that are commonly used in CNC machining.

CNC Turning

CNC turning is a machining process that is most frequently employed to shape workpieces with a cylindrical shape. But, it might also be used for raw materials with square or hexagonal shapes. 

CNC Milling

  This machining technique is utilized to shape/ cut product material in a diverse range of shapes and sizes as compared to turning.  One of the most widely used kinds of CNC machining procedures is CNC milling. In reality, a lot of expert machine shops frequently switch between the CNC machining and CNC milling processes. Two applications for CNC milling that are most commonly utilized are face and peripheral milling.

Drilling

A rotating cutting tool is used in the CNC drilling process to create round holes in the sample. Usually, the holes are designed to take machine screws or bolts for installation needs. Nevertheless, they may be employed for aesthetic reasons as well using different kinds of drill bits as displayed below.

Boring

Internal machining of a hollow workpiece or in a hole previously created by drilling or other methods. Dimensional errors may result from the boring bar’s deflection.

Broaching

Several teeth are used in broaching to machine flat surfaces, gear teeth, holes, and keyholes on the inside or outside. The broach tool is inserted into the workpiece by pushing or pulling.

8. Materials Selection for CNC machining

The choice of material is based on the requirement of the finished product. CNC machining offers a vast variety of materials, you may choose any kind of material according to your requirements. But choosing the right material is very essential to get great output. Therefore, you must have some knowledge about what kind of material you are going to choose for your project. So,  a common distinction between the materials commonly used in CNC machining is elaborated on below
