Machining is a manufacturing process whereby a desired shape or part is achieved by the controlled removal of material from a larger piece of raw material by cutting; most often performed with metal material. These processes are collectively called subtractive manufacturing, which utilizes machine tools, in contrast to additive manufacturing, which uses controlled addition of material.
Machining is a major process of the manufacture of many metal products, but it can also be used on other materials such as wood, plastic, ceramic, and composites. A person who specializes in machining is called a machinist. As a commercial venture, machining is generally performed in a machine shop, which consists of one or more workrooms containing primary machine tools. Although a machine shop can be a stand-alone operation, many businesses maintain internal machine shops or tool rooms that support the business's specialized needs. Much of modern-day machining is carried out by computer numerical control (CNC), in which computers are used to control the movement and operation of mills, lathes, and other cutting machines. This increases efficiency, as the CNC machine runs unmanned, reducing labor costs for machine shops. So far, CNC milling machines that combine turning and milling have even been developed, called CNC turning-milling compound centers.
From engines to appliances to all kinds of mechanical products, parts made via machining are everywhere in our daily lives.Machining processes involve precisely cutting material into a desired shape to create parts that meet specific functional needs. These common processes can be performed manually or programmed on a computer-as in CNC (computer numerical control) machining.
CNC machining is a form of automation that enables a repeatable sequence of multiple, precise machining processes, making high-quality workpieces in far less time than they take to make manually.
The major downside to CNC machining is that you need some serious dough to purchase these machines. Even then, you will likely need to machine your initial fixtures on a manual machine.
The price for your two basic pieces of CNC equipment-a CNC milling machine and a CNC lathe-can be upwards of a hundred thousand dollars for two high-quality machines and all the tooling required to run them. Meanwhile, you can get two manual machines for just a few grand.
Keep in mind that all the machining processes are a form of subtractive manufacturing, meaning they work by removing material. Think of it as precision sculpting-uncovering the part inside the material.
On the other hand, additive manufacturing techniques also are gaining popularity. This approach involves creating a part layer by layer from a digital model. Additive machining is basically a type of 3D printing, so we’ll continue to focus here on the traditional subtractive machining processes.
Unlimited Materials
Machining techniques can work on all types of materials. This is a major advantage over additive manufacturing techniques which work only on a limited set of materials.
Surface Finish
Machining processes create a very smooth surface on the workpiece. An even greater smoothness can be achieved with processes like grinding. Processes like etching can further push the boundary of what is possible in terms of surface finishing.
Precision
CNC machining has some of the lowest tolerances in industrial manufacturing processes. In fact, many CNC machining processes come under the umbrella term of ‘precision machining’. Machining tolerances can be as low as +/- 0.001″.
Production Rate
CNC machining is a high speed process. Therefore, it can easily meet the demands of mass production. Additionally, techniques like multi-axis machining further speed up the production rate.
Consistency
Machining processes are highly consistent in terms of outcome. Consistency is a major requirement for most industries. Machining techniques always produce identical parts.
Less Labor Intensive
A CNC machine is highly automated equipment. It frees up most of the human labor for other high-priority tasks. A CNC machine generally requires labor only for loading and unloading of parts. Besides that, only one operator is enough to oversee the machine operation.
Automotive Industry
There are various parts in a vehicle which require the precision of machining. From engines to steering and transmission systems, you can find machined components all over. This is why automotive industry is one of the largest users of machined components.
Consumer Goods
Competing with automotive industry for the consumption of machined components are consumer goods. From light fixtures to laptops and mobile phones, from different kitchen appliances to smart home equipment, there are various metallic as well as non-metallic consumer goods utilizing the precision of machining.
Aerospace Industry
One of the reasons for the overall adoption of machining technology in standard production in the 1900s was because of the use of the tech to facilitate spare parts production for military vehicles and planes during the second world war. And that heritage of using machined components in planes and flaying machines has not gone even. Even more so now as consumer drones are utilizing the technology to construct long lasting and sturdy machines.
Medical Industry
The thing with medical instruments are they need to be extremely reliable and produced in a controlled environment. While there are ways to sterilize equipment, most doctors prefer machined parts for their tools whether it is operating on a patient or just simply taking care of them in the ward. You can also find machined components in surgical machines, beds and other hospital equipment.
Machining is the process of removing material on a workpiece in order to create a precise object or part. The following are the primary processes used to cut and subtract material in a machine shop by a machinist.
Turning
Turning is a process that rotates the workpiece as the primary method of moving metal against the cutting tool. Lathes are the principal machine tool used in turning.
Milling
Milling uses a rotating cutting tool to bring cutting edges to bear against the workpiece. This is the most versatile tool and technique used in a machine shop.
Drilling
Drilling creates a new hole or refines an existing hole using a rotating cutter. Drilling is most commonly done using drill presses, but sometimes drilling tools will be attached to compatible lathes or mills to create holes.
Boring
Boring is one of the most widely used techniques in machining, as it is one of the most reliable ways to finish and enlarge pre-existing holes. This technique provides accuracy and is easily replicated on a workpiece.
Reaming
Reaming is a process that uses a rotary cutting tool to smooth an existing hole in a workpiece. This is a cutting process that removes material, and its primary purpose is to even out the walls of a hole.
What Materials Can be Machined?
At times it can be difficult to decide which type of machining materials you need to use for your product. Does it need to be malleable? Must it possess properties that are resistant to corrosion? These are the types of questions that should be asked in the beginning stages of production for your application or equipment.
Brass
Brass, known for its stability and low strength, is one of the easiest and most cost-efficient materials to machine. This type of machining is used across a wide variety of applications and industries. some of which include medical, consumer goods, and electrical. Due to the low friction coefficient and high corrosion resistant properties of brass fittings, they can also be used for applications in engineering, or plumbing & steam work industries. Bearings, pipe fittings, compression fittings, musical instruments, and several other custom parts are also created by machined brass materials.
Copper Alloys
Recognized for being the best electrical conductor, copper is suitable for products like cooling systems and heat exchangers in the automotive industry. Copper has high corrosion resistant properties that make it difficult for this type of material to rust. Its thermal conductivity properties allow for easier shaping during CNC machining. Machined copper parts are often used for engineering applications such as valves, hydraulic tubing, and radiators.
Aluminum
CNC machining for aluminum parts can be completed quicker than other metals, making them the most economical machined material. These particular parts form an extra protective layer when exposed to the atmosphere which provides for extra strength and corrosion resistance. Aluminum is best used when creating aluminum gears, spline shafts, worm gears, and other similar parts.
Steel
Most steel alloys (1018, 1215, 12L14, 1215 Bi) are case hardened and are designed for excellent machinability. This material is typically used for parts that require better formability and stronger welds, such as commercial products. Steel alloy 1137 is directly hardened and is frequently used for higher stress applications including gears, shafts, and studs.
Alloy Steel
Many steel alloys are machined for high-stress applications, as well as bearing applications. This material is subject to both direct hardening and case hardening. Depending on the type of steel alloy, this material can also be heat treatable.
Stainless Steel
There are several stainless steel alloys and many can be heat treated and possess corrosion resistant properties. While some stainless steel alloys are machined for surgical equipment and electronic hardware, others are useful for applications that require more formability and weldability. This material is also a top choice for components in the aerospace and automotive industries.
Titanium
Titanium’s high melting point makes this material a perfect option for numerous industries and applications. This material is also resistant to corrosion and protects against ductile and salt and water. While bio-compatible and lightweight, titanium is a strong and sturdy material frequently machined for aircraft and medical implants.
Plastics
There are three forms of machined plastics: PVC, nylon, and Delrin. All three types can be machined for insulators. Bearings and short-run products for injection moldings are made from nylon. While very similar to nylon in color and properties, Delrin provides for better machinability.
Stages of the Machining Process
The machining process for any component goes through these steps in this very order.
Creating Blueprints
Firstly, it is important to create a conceptual idea of the part that is required. This is done through engineering drawings and blueprints of the part, with the intended dimensions mentioned on the blueprints. When specifying the dimensions, it is important to keep in mind the workability of materials and their mechanical strength. For instance, a wall should have a minimum thickness or the part can collapse in the machining stage itself.
Creating CAD Models
Once the blueprints of the part are ready, it needs to be converted into a digital 3D model. This is done by using Computer Aided Design (CAD) software. This is the job of a programmer. More complex parts require complex CAD programs. The CAD models are converted to Computer Aided Manufacturing (CAM) programs. The CAM program is the language that the CNC machine understands. CAD programs can also tell if there are any issues with the design that will give errors in the machining process.
Machine Setup
The machine setup is carried out by the operator and involves adjusting the tooling and mounting the workpiece materials on the CNC machine. The setup can vary based on the type of machining process that will undergo. Setup also includes transferring the CAD instructions to the machine.
Program Execution
Once the machine is ready, the operator executes the program. The machine then works on shaping the program to the final part. It can be done in a number of ways, depending on the particular machine being used. After execution, the final part is ready and unmounted by the operator. Based on the requirement, it can be then sent for secondary machining processes.
Kinds of Cutting Tools Used in Machining
Lathe
If you have ever wondered how to turn stairway posts, a lathe is the answer. The lathe of a machinist functions like a wood-burning table, but gives the power and precision for milling metal. Mount the material at each end to the lathe, then turn the lathe and press the cutting edges against the material as it rotates. You can also manually press cutting edges against the material, or program and operate the cuts via computer input.
Drill Press
The drill press bores precision holes, reams openings and cuts threads. The drill press features an arm that suspends a drill over a stationary base. Put the material at the base, then activate the drill and lower it through the material. Drill presser lower on a fixed axis; they cut precisely straight up and down.
Milling Machine
A machine otherwise known as metal mills; milling machines refer to a variety of metal cutting and shaping machines that can be specially built, commercially available or proprietary. Programmable milling machines that perform numerous cutting operations on various axes are called CNC machines. Most milling machines feature mobile, rotary cutting tools that pierce, cut and shape a piece if fixed material.
Handheld Rotary Tools
The spin attachments of rotary tools, called bits, are used for carving, cutting, reaming and de-burring. Handheld rotary tools usually weight less than a pound and, because their attachments are small, can be used to complete detail or precision work by hand.
Welders
Welding tools use ultra-hot, concentrated flame to cut through material. A welders flame can melt its way through hard and thick materials without physical resistance. However, this usually results in rough or dirty edges.
Grinder
A handheld power tool that spins abrasive or sharpened discs to grind, shape and cut materials. The portability of the grinder allows it to cut and shape in areas where stationary cutting tools cannot.
Chop Saw
The chop saw is a stationary rough cutting tool that can be used to cut materials to length. A chop saw features a spinning abrasive or sharpened blade suspended from an arm above a stationary base. When lowered, the blade cuts through material resting on the base in a chopping motion.
