What Is CNC Machining

CNC Machining is short for Computer Numerical Control Machining, and these machines can achieve an accuracy and consistency that would be hard to match with a manual process. Using pre-programmed computer software, CNC machines can produce items more quickly and with better surface finishes.

Advantages of CNC Machining

More Accurate and Has No Defects
One of the major CNC machining benefits is accuracy. Because CNC machines receive precise instructions from a computer - and the movements are similarly carried out under computer control - their results will be identical each time and will match the computer model closely.

Offers More Rapid and Effective Production
Another industry-cornering CNC machining benefit is the inherent speed and efficiency of production. CNC machines are capable of producing products much more quickly and efficiently than traditional methods. Many modern units can even load the billet and unload the completed product without human intervention.

Makes Assembly Faster
Products whose components are created under computer numerical control are simpler to assemble. Because CNC machining is so precise and consistent, companion parts will fit together exactly as they do on the computer. And since the process is quicker than manual machining, you'll spend less time waiting for parts to be completed. Unless there is a problem in the computer model, all parts should fit together perfectly.

Uses Little Energy
CNC machining uses less electricity than older processes, thereby reducing energy consumption. In fact, according to the EPA, CNC machining uses about one-seventh of the energy of traditional machining methods. There are multiple reasons; CNC machines not only work quickly but draw less power per minute than most other manufacturing methods.

Reduces Production Costs
CNC machining is an economical, efficient, and precise process of manufacturing parts and products. CNC machining also uses fewer raw materials in comparison to conventional machining. Focusing your shop around CNC technology will drastically reduce errors, production expenditures, and product costs.

CNC Machining Materials

The CNC machining process is suitable for a variety of engineering materials, including:
•Metal (e.g., aluminum, brass, stainless steel, alloy steel, etc.)
•Plastic (e.g., PEEK, PTFE, nylon, etc.)
•Wood
•Foam
•Composites

The optimal material for selection to apply to a CNC manufacturing application is largely dependent on the particular manufacturing application and its specifications. Most materials can be machined provided that they can withstand the machining process - i.e., have sufficient hardness, tensile strength, shear strength, and chemical and temperature resistance.

The workpiece material and its physical properties are used to determine the optimal cutting speed, cutting feed rate, and depth of cut. Measured in surface feet per minute, the cutting speed refers to how fast the machine tool cuts into or removes material from the workpiece. The feed rate - measured in inches per minute - is a measure of how fast the workpiece is fed towards the machine tool, and the cut depth is how deep the cutting tool cuts into the workpiece.

The workpiece will first undergo an initial phase in which it is roughly machined to the approximate, custom-designed shape and dimensions, and then undertake a finishing phase in which it experiences slower feed rates and shallower cut depths to achieve its more precise and accurate specifications.

Types of CNC Machining Support Software

The CNC machining process employs software applications to ensure the optimization, precision, and accuracy of the custom-designed part or product. Software applications used include:

CAD

Computer-aided design (CAD) software are programs used to draft and produce 2D vector or 3D solid part and surface renderings, as well as the necessary technical documentation and specifications associated with the part. The designs and models generated in a CAD program are typically used by a CAM program to create the necessary machine program to produce the part via a CNC machining method. CAD software can also be used to determine and define optimal part properties, evaluate and verify part designs, simulate products without a prototype, and provide design data to manufacturers and job shops.

CAM

Computer-aided manufacturing (CAM) software are programs used extract the technical information from the CAD model and generate machine program necessary to run the CNC machine and manipulate the tooling to produce the custom-designed part. CAM software enables the CNC machine to run without operator assistance and can help automate finished product evaluation.

CAE

Computer-aided engineering (CAE) software are programs used by engineers during the pre-processing, analysis, and post-processing phases of the development process. CAE software is used as assistive support tools in engineering analysis applications, such as design, simulation, planning, manufacturing, diagnosis, and repair, to help with evaluating and modifying product design. Types of CAE software available include finite element analysis (FEA), computational fluid dynamics (CFD), and multibody dynamics (MDB) software.

Some software applications have combined all of the aspects of CAD, CAM, and CAE software. This integrated program, typically referred to as CAD/CAM/CAE software, allows a single software program to manage the entire fabrication process from design to analysis to production.

Application of CNC Machining

Electronics

For the electronics industry, the types of parts required are the opposite of those used by the oil and gas industry and is the reason that CNC machining is a vital part of electronic parts development and production. Most of the parts and components used by the electronics industry are similar to those that motivated the development of Swiss CNC machining. Though accuracy is critical, the main concern is size since much of what is used in electronics is very small but has to be very precise and properly dimensional.

Telecommunications

The accuracy, dependability, and high tolerances of CNC machining are critical to the telecommunications industry since failure can have severe ramifications. The first and most vital factor for telecommunications parts is durability and indestructibility since a breakdown or error can create insurmountable and critical difficulties.

Aerospace

Components produced for the aerospace industry have to endure high speeds, rapid air currents, and high pressure. Every part, piece, and component of an aircraft has to be precisely engineered and designed to meet the demanding conditions. The requirements of the aerospace industry need tolerances of 0.0004 inches. CNC machines meet the demand for high tolerances by machining very durable materials.

Automotive

Of the many industries that use CNC machining, the automotive industry has the greatest need and makes the most use of the efficiency and excellent turnaround times for CNC machined parts. The auto industry is constantly seeking better and more efficient methods for producing components and parts. It has been the leader in developing technological advanced methods, which is the reason that it was one of the first industries to make extensive use of CNC machining.

Understanding CNC Machining

CNC machining is considered a subtractive manufacturing technology, which means that the end product is formed by selectively removing excess material from the workpiece. Every end-to-end CNC machining operation follows a similar four-step production process.

These Four Production Phases Are:

Part Design
Parts produced via CNC machining generally start out as initial designs from Computer Aided Design (CAD) software. In the design phase, engineers give careful thought to all aspects of the desired final product, such as parameters for optimal performance, operating conditions for the end part, and acceptable tolerance variation levels.

Design Conversion

Upon completion of the initial design phase, the CAD model must be converted into a functional CNC program using Computer Aided Manufacturing (CAM) software. CAM software is able to extract the geometrical requirements from the CAD model’s origin file and translate them into a CNC-compatible programming language - such as G-code or M-code - which will dictate the mechanical operations of the machine.

CNC Machine Preparation

The CNC machine operator must set up both the machine and the target material according to the specifications required by the CNC program. The operator will ensure that the correct cutting or drilling tools are properly installed and are matched with the appropriate bits or end mills. The operator must also set up the workpiece, typically either in a stationary clamp or attached directly to the CNC machine.

Executing Programmed Operations

The CNC machine operator executes the desired mechanical processes. During operation, the CNC program precisely controls the movements of the machine tooling.

Is CNC Machining Better Than Conventional

CNC machining and conventional machining aim to achieve the same end, and both start with a raw chunk of metal or plastic and shape it into a part. The most basic difference between the two is the automation of CNC versus the manual nature of conventional. Speed, production rate, and accuracy are some of the main advantages of CNC machining over conventional machining.

With CNC, a skilled employee programs software to cut the part. With conventional, a skilled employee takes all the steps to setup and operate the machine. In the manual situation, a highly skilled operator must also set the gears, whereas CNC machining does not use gears.

Conventional typically costs less and is used for small-quantity projects. CNC machining is normally used for high quantities and is not as cost-effective for smaller ones.

Imagine a hypothetical part, for example. A component needs concave and convex arcs, imperial and metric threads and two tapers of differing degrees. An automated CNC machine would use three tools to cut the part, while the conventional machine would require five tools and no doubt more time.

Among the first things to happen with CNC machining is the use of computer-aided design (CAD) software to produce a two- or three-dimensional model of the final component. The prototype image of that component is then fed into the software, which operates through the computer to command the machining tools to produce items identical to the model.

Once the computer has loaded in a new image for CNC machining, it can pull that model up again and again to produce more of what it is, which is another of the CNC machine advantages. The technology is designed to achieve machining accuracy within 0.0001.
