Precision manufacturing relies heavily on computer numerical control (CNC) machining, including operations that once used engineers to operate equipment such as routers, molding machines, vertical milling machines and center lathes. Manufacturers in many industries choose CNC machining because it provides efficient, convenient and accurate production capabilities that are well suited for producing large quantities of items that are typically produced using grinders, routers, center lathes or molding machines.
Whereas in manual turning, a skilled technician must be available for each machine, in CNC machining, one skilled person can operate multiple machines. Because of its precision, consistency and intricate cuts, CNC machining can produce a wide range of metal parts used in many industries.
Some examples of these industries are: aerospace, automotive, electronics, firearms, hospitality, manufacturing, metalworking, military, production and transportation. The first CNC machines were developed by U.S. Air Force machinists in the 1940s. These early machines used punched paper technology as the driver and have evolved into the digital software of today. CNC machining has become popular because of its ability to produce detailed and accurate results using computers in large quantities.
Computer numerical control differs from a typical PC in that the software used to control the machine is specifically tailored and programmed using CNC-specific G-code, which allows precise control of speed, position, coordination and feed rate. One person can delegate machine work, which is equivalent to multiple operators working on lathes, grinders, routers, mills and molding machines, which are not always done efficiently by human operators and conventional machines.
The manufacturing sector finds CNC machining very useful because the industry requires a large number of metal and plastic parts, often with complex shapes. Different types of CNC machines have the advantage of multiple axes that can adjust difficult angles and help manage difficult-to-cut materials.
Basic machines have cutting tools along the x and y axes, each working independently and simultaneously. Advanced machines may have up to five axes that perform similarly and are capable of turning and flipping parts. CNC machines can automate jobs that require multiple cuts. A router or spindle turns a cutting tool similar to a drill and cuts the material, while a real drill only cuts at the tip.
The programming in CNC machines combines all the precise, high-speed movements needed to produce objects with detailed customization. CNC machining is becoming increasingly popular for making metal parts and plastic parts because it allows manufacturers to produce complex shapes that are nearly impossible to create manually.
Both CNC and conventional machines start with a piece of unmachined metal or plastic, which is then molded into a part. The main difference between the two machines is the automation of the CNC versus the manual nature of the traditional. Speed, productivity and accuracy are some of the main advantages of CNC machining over traditional machining.
Skilled employees program software to cut parts in CNC machining while employees set up and operate the machine and gears. Conventional is less costly and is typically used for small volume projects. CNC is used for larger volumes and is not as cost effective for smaller projects. CNC machines use three tools to cut parts, while conventional machines require five tools and more time to complete the job.
Most machining jobs can use both conventional and CNC technology. Some of these include drills – where the drill bit rotates to make contact with the material, lathes – where the block of material moves against the drill bit, usually in a transverse motion and mills – where the rotating cutting tool removes material from the stock unit to remove material. Newer CNC machining techniques include fewer common types, such as electro/chemical, in which blocks of material are cut using specific types of machining (e.g., electron beam, electrochemical, electrical discharge, photochemical, and ultrasonic).
Less common CNC machining methods involve cutting media such as lasers, oxy-fuel, plasma and water jets.

Precision parts: CNC’s digital templates and autonomous machining virtually eliminate human error with an accuracy of 0.01mm.
Reliable and durable: CNC machines work 24/7 every day and are only used for repairs or maintenance.
High throughput and scalability: Once design parameters and specifications are entered into the CNC machine, it consistently performs a large number of operations and offers flexible scalability.
More versatility: When used with advanced design software, CNC machines can create output that cannot be replicated by manual machines. Thanks to advanced software, even the most talented engineers cannot achieve the level of CNC machines using conventional machines. These machines can produce any size, shape or texture desired.
Less labor: CNC machining requires fewer people to perform production tasks. A skilled operator can run multiple autonomous CNC machines while another programmer can have them loaded with designs. A manual machine requires at least one skilled operator and one supervisor per machine. The labor you save can be passed on to your customers.
Unified product: When you use a CNC machine instead of a conventional machine, your CNC output matches exactly. Even the most talented machine operator running a conventional machine will have a very slight product from them. CNC machines guarantee perfect parts every time.
Lower cost: CNC machines are faster, more efficient, more accurate, and require fewer man-hours. Saving money or making more money is one of the popular benefits of CNC machining.
Less hassle: Manual machines have many uses, but you won’t be able to produce as well as you can with CNC machines when your operators are not available, or when your employees don’t meet their expectations.
Better safety: While CNC machines still require the use of an operator, they are kept at a distance from sharp tools. Traditional manual lathes, drill presses and punch presses have operators in direct contact with the tools.
Design Retention: Once the design is loaded into the CNC machine software and a perfect prototype is created, the program can easily retrieve the design and recreate the object.
Low maintenance: G-code-based software is automatically updated when needed, and CNC machines typically require little service, requiring only cutting tool changes at appropriate intervals. Professional service is not required for any regular maintenance.
Versatility: CNC machining can create virtually any component. Some models include special features and accessories that can further speed and simplify the production process
