How to Streamline Part Design for Computerized Numerical Control Machining

Experts believe that computerized numerical control technology has transformed the production and component designing space. While computerized numerical control machining technology has existed for a while, it provides high-quality precision machining and several more advantages in manufacturing components. Nevertheless, designers must understand and learn specific manufacturing rules to maximize the utilization of computerized numerical control machining technology. These rules will be crucial in streamlining component designs for computerized numerical control machining. Spending quality time enhancing and assessing the component design for computerized numerical control machining will lower the production cycle, decrease cost and improve efficiency and component quality. This blog tries to answer the question of how to streamline component design for computerized numerical control machining by discussing some rules below.

Selecting the Right Material

The kind of machining substances for computerized numerical control machining will affect the performance and cycle times. Regarding selecting suitable materials, factors like the component's use, component design, entire machining structure, durability, and load to machining need to be considered. This will help manufacturers produce high-quality components after manufacturing. Also, these qualities of substances and tooling behavior would affect machining tool factors. These encompass spindle motor torque, highest spindle speed, motor power, and feed rate.

Overall, to determine the qualities you need, describe the function of computerized numerical control milled components, the atmosphere it would work in, and the material's stress load endurance. This would let you streamline the component design for computerized numerical control machining. A broad range of materials are available for CNC milling machining; the most common are plastics and metals.


In the computerized numerical control machining space, makers utilize different metals for computerized numerical control machining components. These encompass copper, steel, stainless steel, brass, aluminum, and others. Many makers prefer aluminum and other soft metals due to their ease of machining. Furthermore, these computerized numerical control materials are machined in less time. They have a lesser weight and are usually less costly.

Nevertheless, these materials cannot tolerate much stress compared to sturdy metals like stainless steel and carbon steel. Hard metals such as steel are of significant consideration where strength is needed. The disadvantages of these kinds of metals are that their weight is greater and consumes more time to machine, which significantly adds to the project's cost.


Plastics fail to provide the strength and rigidity of metals; they are cost-efficient options for a project. Regardless of this, the use of plastic material depends on the components' utilization. Thus, a manufacturer must streamline their component's design. Plastic materials are simple to machine at a lower cost, but it's tough to attain tight tolerances and more prone to warping.

Consider Design Constraints

Regarding streamlining a component design for computerized numerical control machining, manufacturers need to consider their designs' complexity. This will let them plan what kinds of tools they need for computerized numerical control machining operations. Access to computerized numerical control machining instruments is an ideal limitation for computerized numerical control manufacturing. This is because reaching numerous faces on a workpiece is dependent on how much a machining instrument could simply revolve respectively in a short time. If manufacturers find their component design complex, they should continuously recalibrate to adjust their equipment by employing a new coordinate system. This consequently increases the cost and time a manufacturer needs to complete a project. To deal with this constraint, there should be easy access to various machining instruments such as 5-axis,4-axis, and 3-axis computerized numerical control machining instruments. Of these kinds, the 5-axis can deal with complicated designs simply.

In streamlining their component designs for computerized numerical control machining, revolving a workpiece four or less than four times must not be difficult. Manufacturers can simply machine complicated component designs using a five-axis computerized numerical control machine. Whereas it is efficient for complicated design, the instruments cannot deal with internal geometries. Thus, manufacturers should employ specialized tools to deal with internal geometries. After the availability of these tools, people can simply streamline their component design for computerized numerical control machining. 

Consider Magnitude Constraints

The magnitude of the component design poses a constraint making the entire part size an important consideration when designing it. The size of a component could be limited through equipment capabilities available for production coupled with the cut's depth required for developing a high-quality part. Designers must keep these factors in their minds, particularly if the plan is to utilize milling or lathe machines. For milling, magnitude is an important consideration. Whereas equipment could penetrate thirty-eight inches alongside the Y axis, machining a component to that level or height might be tough. This tells us that the feature and magnitude of the workpiece should be a little lesser than thirty-eight" to permit for the depth of the tool and cut tolerance. Thus, a design magnitude is another essential factor in streamlining their component design for computerized numerical control machining.

Be Careful of the Accuracy

To streamline their component's design for computerized numerical control machining, manufacturers need to take care of the precision and accuracy. Maintaining precision and accuracy is dependent on the following procedures and processes, which should be prioritized.

Working Atmosphere

Your component's accuracy is dependent on the working atmosphere that provides stable conditions, encompassing pressure, temperature, humidity and many more.

Machine Condition

Computerized numerical control machining needs constant preventive upkeeping to let manufacturers keep all their machining equipment in ideal running condition.

Equipment Calibration

Recalibrating computerized numerical control machining regularly is an ideal method to guarantee precision and accuracy in producing parts.

Tool Monitoring

Manufacturers must monitor all computerized numerical control machining machines as they simply wear out. Then appropriate replacement and maintenance must be guaranteed. 

Work Holding

To attain precision and accuracy, manufacturers should minimize vibration by utilizing appropriate work-holding setups to secure their workpieces for the machining procedure. 


Manufacturers must employ qualified production engineers who comprehend how to utilize various tools with various approaches and speeds to efficiently make accurate computerized numerical control milled components. 

Machinist Experience

Engineering professionals with more computerized numerical control machining experience will more probably grasp the subtle differences that can help guarantee accurate component production.

What is The Typical Tolerance for Injection Molded Parts?

An immense number of plastic products are produced every day in the world. From a bottle cap to an entire plastic tank, thousands of products are manufactured with the help of plastic injection methods in the plastic industry. It seems so simple because of the metallic molds that are used in this process. All you need to do is add polymers in the injection and fill the mold with high temperatures to get the shape you want. But the casting needs a precise mold for that. Without that mold, you can’t produce thousands of plastic products a day. This is what we are going to learn in this blog. How these metallic molds get accurate designs and shapes is what you need to know here.  With the help of CNC machines, you can make any metallic mold to operate the plastic injection process. How do these CNC machines produce such sharp and detailed molds for any kind of unique plastic product? That is only possible if you have highly efficient CNC machines. Even if you don’t have that, you can get metallic molds from a CNC plastic parts factory. You will be able to get durable metallic molds to process plastic injection production easily. Let’s see what makes these CNC machines perform this task with much efficiency. Tolerance Level for Plastic Injection Molded Parts Tolerance level is the main factor here, which makes the mold sharp. The tighter the tolerance level, the sharper the edges are. Normally, an average tolerance ranges between +/- 0.002 inches and +/- 0.005 inches for plastic molds. Each production type has a different level of tolerance. If you go for tighter tolerance for injection molding, it will be +/- 0.002 inches. Moreover, if you further go for the tightest tolerance, it reaches +/- 0.001 inches. This is the minimum tolerance level to design a complicated mold for the plastic injection process. As a result, you will have to choose the tolerance extreme to meet unique designs and shapes of molds. Due to detailing this is a very important part of this method. However, there is a cost issue. Tighter tolerance causes a higher cost of production and also more time consumption. Resultantly, you will get the complex design of the mold, but its cost will be higher than a simple one. That is a crucial thing you need to keep in mind while using a CNC machine in mold manufacturing.  Ways to Achieve that Tolerance Level There are some simple ways to achieve a tolerance level for plastic injection molds. Since these molds need to be very smooth and precise in terms of design, they need a strict tolerance level. You can achieve that level by using these simple tricks with your CNC machines.  High Spindle Speed The spindle motor is a very important component in speed management. You can get a very high accuracy through it. Normally, the spindle motor’s speed ranges between 24000 RPM and 30,000 RPM. In addition, the spindle motor’s speed has different ranges according to the type of material and handling. For plastic molds, we can go for this range. Having a speed of around 24000 RPM will be ideal in this case. It will keep the precision level at an accurate mode. Make sure you don’t cross this speed range because the spindle motor has a limit, and different sizes of spindle motors are used for it. If you are going for less precision, you need an average motor for basic speeding.  Carbide Type When it comes to milling, drilling, and cutting in a CNC machine, carbide has to do this task. In this way, carbide has to be tough enough to meet all the requirements. Normally, each carbide type has a different grade in this process. Each Grade has different levels of endurance and performance. For plastic injection molds, we use C2-grade carbides. This C2 Grade helps to meet detailing with smooth results. You can use C2 or even C1 Grade for that purpose. Mostly. C2 Grade of carbide is used for it.   Wall Thickness Level Another factor is the wall thickness level. In CNC machining, this factor has to be ensured for high accuracy of injection molding of plastic parts. The wall thickness is between 0.5 mm to 27 mm, usually for plastic parts molds. Plastic types like ABS, acrylic, polyethylene, polyester, etc., are used for this range of wall thickness. You can make molds with CNC machines by maintaining the wall thickness level as per your requirement. Some plastic types need wall thickness levels between 0.5 to 0.7 mm, some need 1 mm to 2 mm, and so on. You need to decide what kind of mold you need to manufacture and what kind of plastic-type will be injected into it. According to that, you will be able to produce the best standard of mold.  That’s all you can have here. If you can produce your own molds, you need a CNC machine for that. Otherwise, you can order molds from a bulk supplier.
