What Is The CNC Machining Process ?
CNC Machining is a common form of manufacturing process which the material is cutting away to create a variety of desired shapes on the part as per CAD model clients provided .The machining process is that firstly the CNC programmer makes program with the 3D design data .The machinists import the program into machine ,put the original material piece on the platform of machine as well as setting up the fixtures to keep the correct position ,then ,fix the cutting tool ,and start running machine .Any materials almost are available that can be machined ,including Plastic ,Aluminum ,Titanium ,Stainless Steel ,Brass ,Copper etc ,even Foam material if the part shape is not complex .
The advantage of CNC Machining is that the machines can be pre-programmed, so that a certain operation can easily be repeated hundreds or even thousands of times. But each manufactured part will be exactly the same. Moreover, it can be run very precisely, based on pre-made programming which is making from a CAD model, is sent from the computer to the machine. then it knows exactly what object needs to be done .So this process can be a significant to reduce production costs and increase efficiency of manufacturing.
Best-in-class CNC Machining Services
CNC machining is a manufacturing process that employs computerized controls to operate and manipulate machine and
cutting tools to form stock material—for example, metal, plastic, wood, foam, composite, and so on—into custom parts and designs.
Although the CNC machining process provides various capabilities and activities, the basic concepts of the process remain relatively consistent across all of them. The following stages get included in the basic CNC machining process:
- Designing the CAD model
- Converting the CAD file to a CNC program
- Preparing the CNC machine
- Executing the machining operation
Rapid CNC Machining is usually the best method, short of tooling, to fit proposed production-part properties for prototype and low volume manufacturing of custom metal and plastic parts. We use your 3D CAD model to generate precision CNC machining paths that guide our equipment to follow every contour and hole. The result is a precisely replicated component that exactly matches your initial CAD model design. At the same time, 3D printing is becoming increasingly common, limited to most materials. It is not printable. As a result, CNC machining is a solution to the problem. It can machine the original materials that clients need.
Key Advantages Of CNC Machining
The benefits of CNC machines over traditional machining methods are numerous; these machines use higher levels of automation and eliminate potential errors while increasing overall efficiency and cost-effectiveness. Here is a list of the critical benefits of CNC machines:
Productivity
Since we can program a CNC mill or other computer to perform a complex series of acts, you can often step away as the machine gets to work. It can involve after-hours automated machining in some setups, which can significantly increase the efficiency and rate of output. It is especially true for precision engineers who run several CNC centers, such as ours.
Cost-Effectiveness
CNC machines more than makeup for their initial costs due to their high production rate and lower number of errors in resulting parts. Operators often need less instruction to use a CNC machine and learn how to use the machine virtually, reducing the need for training workpieces. The cost of these devices will continue to fall as they become more common and widespread.
Consistency
Since a CNC almost removes human error, CNC machines generate highly reliable and precise work, providing clients with standardized and faultless goods. CNC machining is necessary for areas where quality is vital because the reliability and quality in work generated are much higher.
Safety
Unlike standard open guard machining, any dangerous safety problems, such as a jam or other machining mistake, are only harmful to the machine and do not pose a safety risk to the user.
Versatility
We can quickly reprogram CNC machines to create an entirely new product, making them suitable for short or long production runs. We can change programming without being time-consuming or expensive.
CNC Machining Tolerances
Learn about the consequences of tightening the tolerance range and how your current tolerance range is affected by different factors to expand your awareness of tolerances for CNC machining.
- Tolerances are the acceptable ranges for dimensions, which get usually expressed as “+/-.” Usually the designers set it up according to the actual request of the object’s shape , fit ,and function.
- The tighter the tolerance, the more money it will cost because there will be more setup requirements, longer cycle times, and more fixturing or specialized equipment.
- If you request a tighter tolerance than the standard tolerance, you might be altering the best manufacturing process for your part.
- Be aware that the feature will get subjected to an inspection process when additional tolerances get set on your components.
- The material used may affect the complexity of producing a component to a given tolerance.
CNC Turning Services
CNC turning is the most efficient method of removing large quantities of material from rounded stock. When combined with an automated bar feeder that provides an uninterrupted supply of raw material into the process, this machining method is also suitable for larger production runs.
When producing large quantities of concentric shapes or threaded features, CNC turning is the only industrial method to use. Furthermore, because of the solid structure of a CNC lathe, there is slight vibration, allowing CNC turning to provide high levels of dimensional precision with excellent surface finishes.
EDM Machining
EDM is a nontraditional precision machining method in which features get produced by the controlled erosion of material using electrical discharges on a normally conductive material workpiece (sparks). Electrical Discharge Machining get based on the separation of two electrodes (one of which is the workpiece) by a dielectric liquid, usually deionized water or oil.
As the field strength between the two electrodes becomes too strong, the dielectric breaks down, current flows through, and material gets extracted from both electrodes. The current flowing between the electrodes is NOT constant; instead, it is instantaneous, generating debris washed out by the fluid. It can replicate this several times to erode a finely controlled feature that would be difficult to produce with conventional machining methods.
CNC Machining Materials
CNC machines can cut almost any material which may resource in the market to meet your specifications. Although numerous materials can get used in a CNC unit, the most widely used materials in industry are as below :
- Plastics— numerous choices such as ABS,Acetal, Acrylics, Polycarbonate (PC), and Polypropylene (PP), to name a few
- Metals — such as steel, aluminum, titanium, magnesium,or brass
- Wood — commonly plywood, hardwood, softwood
- Foam — lightweight but durable. The two main types are rigid foam and carving foam.
CNC Machining Finishes
In short, a post-processing finish, such as anodizing or powder coating, would most likely be a viable choice for pieces that do not need to be picture-perfect but must retain their original dimensions. Anodizing can help protect or reinforce an aluminum or titanium component. Powder coating is an efficient alternative to anodizing if the element cannot be anodized and needs strength and impact resistance. Finally, if cost-effectiveness is more critical than resistance and does not need a glossy finish, bead blasting might be the best option.

Custom Low Volume CNC Machined Parts
Modern low-volume manufacturing is not the same as mass production. With an increased demand for custom parts, this form of manufacturing is becoming increasingly common, so much research and development is aimed at improving the efficiency of flexible manufacturing systems.
CNC machine tools play a significant role in component creation versatility. Just 10-15 years ago, producing a component with some complex surfaces needed a lot of additive manufacturing (i.e., creating a template for the machine tool to follow required manual labor). So difficult parts were get manufactured for mass production or manual labor, which was time-consuming and costly. All of those elements are now get replaced by a CNC application. Furthermore, advanced computer-aided manufacturing systems get created, significantly reducing the time needed to make such a program. Modern tool mechanisms allow the manufacturer to mount many tools on the lathe, reducing the time taken to adjust them during the machining process.
