The success or failure of aerospace operations depends on the accuracy, precision and quality of the components used. For this reason, aerospace companies utilize advanced manufacturing techniques and processes to ensure that their components fully meet their needs. While new manufacturing methods such as 3D printing are rapidly gaining popularity in the industry, traditional manufacturing methods such as machining continue to play a key role in the production of parts and products for aerospace applications. Such as better CAM programs, application-specific machine tools, enhanced materials and coatings, and improved chip control and vibration damping - have significantly changed the way aerospace companies manufacture critical aerospace components. However, sophisticated equipment alone is not enough. Manufacturers must have the expertise to overcome the material processing challenges of the aerospace industry.





Material requirements


The manufacture of aerospace parts first requires specific material requirements. These parts typically require high strength, low density, high thermal stability and corrosion resistance to handle extreme operating conditions.

Common aerospace materials include:

1. High strength aluminum alloy

High-strength aluminum alloys are ideal for aircraft structural parts because of their light weight, corrosion resistance and ease of processing. For example, 7075 aluminum alloy is widely used in the manufacture of aerospace parts.

2. titanium alloy

Titanium alloys have excellent strength to weight ratio and are widely used in aircraft engine parts, fuselage components and screws.

3. Superalloy

Superalloys maintain strength and stability at high temperatures and are suitable for engine nozzles, turbine blades and other high-temperature parts.

4. Composite material

Carbon fiber composites perform well in reducing structural weight, increasing strength and reducing corrosion, and are commonly used in the manufacture of casings for aerospace parts and spacecraft components.





What are the process characteristics of aerospace parts processing?


Process planning and design

Process planning and design are required before processing. At this stage, it is necessary to determine the overall processing scheme according to the design requirements of the parts and material characteristics. This includes determining the process of processing, the choice of machine tool equipment, the selection of tools, etc. At the same time, it is necessary to carry out detailed process design, including the determination of cutting profile, cutting depth, cutting speed and other parameters.

Material preparation and cutting process

In the process of aerospace parts processing, the first need to prepare working materials. Usually, the materials used in aviation parts include high-strength alloy steel, stainless steel, aluminum alloy and so on. After the material preparation is completed, the cutting process is entered.

This step involves the selection of machine tools, such as CNC machine tools, lathes, milling machines, etc., as well as the selection of cutting tools. The cutting process needs to strictly control the feed speed, cutting speed, cutting depth and other parameters of the tool to ensure the dimensional accuracy and surface quality of the parts.

Precision machining process

Aerospace components are usually very demanding in terms of size and surface quality, so precision machining is an indispensable step. At this stage, it may be necessary to use high-precision processes such as grinding and EDM. The goal of the precision machining process is to further improve the dimensional accuracy and surface finish of the parts, ensuring their reliability and stability in the aviation field.

Heat treatment

Some aerospace parts may require heat treatment after precision machining. The heat treatment process can improve the hardness, strength and corrosion resistance of the parts. This includes heat treatment methods such as quenching and tempering, which are selected according to the specific requirements of the parts.

Surface coating

In order to improve the wear resistance and corrosion resistance of aviation parts, surface coating is usually required. Coating materials can include cemented carbide, ceramic coating, etc. Surface coatings can not only improve the performance of parts, but also extend their service life.

Assembly and testing

Do parts assembly and inspection. At this stage, the parts need to be assembled in accordance with the design requirements to ensure the accuracy of the match between the various parts. At the same time, rigorous testing is required, including dimensional testing, surface quality testing, material composition testing, etc., to ensure that parts meet aviation industry standards.





Process characteristics


Strict quality control: The quality control requirements of aviation parts are very strict, and strict testing and control are required at each processing stage of aviation parts to ensure that the quality of parts meets the standards.

High precision requirements: Aerospace components typically require very high accuracy, including dimensional accuracy, shape accuracy and surface quality. Therefore, high-precision machine tools and tools need to be used in the processing process to ensure that the parts meet the design requirements.

Complex structure design: Aviation parts often have complex structures, and it is necessary to use multi-axis CNC machine tools and other equipment to meet the processing needs of complex structures.

High temperature resistance and high strength: aviation parts usually work in harsh environments such as high temperature and high pressure, so it is necessary to choose high temperature resistance and high strength materials, and carry out the corresponding heat treatment process.

Overall, aerospace parts processing is a highly technology-intensive, precision demanding process that requires strict operating processes and advanced processing equipment to ensure that the quality and performance of the final parts can meet the stringent requirements of the aviation sector.





Processing difficulties


Aerospace parts processing is challenging, mainly in the following areas:

Complex geometry

Aerospace parts often have complex geometrics that require high-precision machining to meet design requirements.

Super alloy processing

The processing of superalloys is difficult and requires special tools and processes to handle these hard materials.

Large parts

The parts of the spacecraft are usually very large, requiring large CNC machine tools and special processing equipment.

Quality control

The aerospace industry is extremely demanding on part quality and requires rigorous quality control and inspection to ensure that every part meets the standards.

In aerospace parts processing, precision and reliability are key. A deep understanding and fine control of materials, processes, precision and machining difficulties is the key to manufacturing high-quality aerospace parts.

Thread machining is one of the very important applications of CNC machining center. The machining quality and efficiency of thread will directly affect the machining quality of parts and the production efficiency of machining center.With the improvement of the performance of CNC machining center and the improvement of cutting tools, the method of thread machining is also improving, and the accuracy and efficiency of thread machining are also gradually improving. In order to enable technicians to reasonably select thread processing methods in processing, improve production efficiency and avoid quality accidents, several thread processing methods commonly used in CNC machining center are summarized as follows:1. Tap processing method


1.1 classification and characteristics of tap processingUsing tap to process threaded hole is the most commonly used processing method. It is mainly applicable to threaded holes with small diameter (d30) and low requirements for hole position accuracy.
In the 1980s, the flexible tapping method was adopted for threaded holes, that is, the flexible tapping collet was used to clamp the tap. The tapping collet can be used for axial compensation to compensate the feed error caused by the non synchronization between the axial feed of the machine tool and the spindle speed, so as to ensure the correct pitch. The flexible tapping collet has complex structure, high cost, easy damage and low processing efficiency. In recent years, the performance of CNC machining center Gradually, the rigid tapping function has become the basic configuration of CNC machining center.
Therefore, rigid tapping has become the main method of thread machining.That is, the tap is clamped with a rigid spring collet, and the feed of the spindle is consistent with the spindle speed controlled by the machine tool.Compared with the flexible tapping chuck, the spring chuck has the advantages of simple structure, low price and wide application. In addition to holding the tap, it can also hold the end milling cutter, drill bit and other tools, which can reduce the tool cost. At the same time, the rigid tapping can be used for high-speed cutting, improve the use efficiency of the processing center and reduce the manufacturing cost.
1.2 determination of threaded bottom hole before tappingThe processing of threaded bottom hole has a great impact on the life of tap and the quality of thread processing. Generally, the diameter of threaded bottom hole drill is close to the upper limit of the diameter tolerance of threaded bottom hole,For example, the bottom hole diameter of M8 threaded hole is 6.7 0.27mm, select the drill bit diameter as 6.9mm. In this way, the machining allowance of tap can be reduced, the load of tap can be reduced, and the service life of tap can be improved.
1.3 selection of tapWhen selecting taps, first of all, the corresponding taps must be selected according to the processed materials. The tool company produces different types of taps according to different processing materials, and special attention should be paid to the selection.
Because the tap is very sensitive to the processed materials compared with the milling cutter and boring cutter. For example, using the tap for processing cast iron to process aluminum parts is easy to cause thread dropping, disorderly threading and even tap breaking, resulting in workpiece scrapping. Secondly, pay attention to the difference between the through-hole tap and the blind hole tap. The front-end guide of the through-hole tap is long, and the chip removal is the front-end chip. The front-end guide of the blind hole is short, and the chip removal is the front-end It is the back chip. Machining the blind hole with a through-hole tap cannot guarantee the thread machining depth. Moreover, if a flexible tapping collet is used, it should also be noted that the diameter of the tap handle and the width of the four sides should be the same as that of the tapping collet; the diameter of the tap handle for rigid tapping should be the same as that of the spring jacket. In short, only a reasonable selection of the tap can ensure the smooth machining.
1.4 NC programming of tap machiningThe programming of tap machining is relatively simple. Now the machining center generally solidifies the tapping subroutine and only needs to assign values to various parameters. However, it should be noted that the meaning of some parameters is different due to different NC systems and different subroutine formats.For example, the programming format of Siemens 840C control system is g84 x_y_r2_r3_r4_r5_r6_r7_r8_r9_r10_r13_. Only these 12 parameters need to be assigned during programming.
2. Thread milling method2.1 characteristics of thread millingThread milling adopts thread milling tool and three-axis linkage of machining center, that is, x-axis and y-axis arc interpolation and z-axis linear feed.
Thread milling is mainly used to process large hole threads and threaded holes of difficult to process materials. It mainly has the following characteristics:(1) high processing speed, high efficiency and high processing precision. The tool material is generally cemented carbide, with fast tool walking speed. The manufacturing precision of the tool is high, so the milling thread precision is high.(2) the milling tool has a wide range of application. As long as the pitch is the same, whether it is left-hand thread or right-hand thread, one tool can be used, which is conducive to reducing the tool cost.
(3) milling is easy to remove chips and cool, and the cutting condition is better than that of tap. It is especially suitable for thread processing of difficult to process materials such as aluminum, copper and stainless steel, especially for thread processing of large parts and components of precious materials, which can ensure the thread processing quality and workpiece safety.(4) because there is no tool front-end guide, it is suitable for machining blind holes with short thread bottom holes and holes without tool return grooves.2.2 classification of thread milling tools
Thread milling tools can be divided into two types, one is the machine clamp cemented carbide blade milling cutter, and the other is the integral cemented carbide milling cutter. The machine clamp cutter has a wide range of applications. It can process holes with thread depth less than the blade length or holes with thread depth greater than the blade length. The integral cemented carbide milling cutter is generally used to process holes with thread depth less than the tool length.2.3 NC programming of thread millingThe programming of thread milling tool is different from that of other tools. If the processing program is wrong, it is easy to cause tool damage or thread processing error. The following points should be paid attention to during programming:
(1) firstly, the threaded bottom hole shall be processed well, the small diameter hole shall be processed with a drill, and the larger hole shall be bored to ensure the accuracy of the threaded bottom hole.(2) when cutting in and cutting out the tool, the arc path shall be adopted, usually 1 / 2 turn, and 1 / 2 pitch shall be traveled in the z-axis direction to ensure the thread shape. The tool radius compensation value shall be brought in at this time.(3) the x-axis and y-axis circular arc shall be interpolated for one week, and the main shaft shall travel a pitch along the z-axis direction, otherwise the threads will be buckled disorderly.
(4) specific example program: the diameter of thread milling cutter is 16. The threaded hole is M48 1.5, the depth of threaded hole is 14.The processing procedure is as follows:(the procedure of threaded bottom hole is omitted, and the bottom hole shall be bored) G0 G90 g54 x0 y0g0 Z10 m3 s1400 m8g0 z-14.75 feed to the deepest thread G01 G41 x-16 Y0 F2000 move to the feed position, add radius compensation G03 x24 Y0 z-14 I20 J0 f500 cut in with 1 / 2 circle of arc G03 x24 Y0 Z0 I-24 J0 F400 cut the whole thread G03 x-16 Y0 z0.75 I-20 J0 f500 cut out with 1 / 2 circle of arc G01 G40 x0 Y0 return to the center and cancel radius compensation G0 Z100M30
3. Snap method3.1 characteristics of snap methodLarge threaded holes can sometimes be encountered on box parts. In the absence of tap and thread milling cutter, the method similar to lathe pick-up can be adopted.
Install the thread turning tool on the boring bar to bore the thread.The company once processed a batch of parts with m52x1.5 thread and 0.1mm positional degree (see Figure 1). Because of the high positional requirements and large thread hole, it is impossible to process with tap and there is no thread milling cutter. After the test, the thread picking method is adopted to ensure the processing requirements.3.2 precautions for buckle picking method
(1) after the spindle is started, there shall be a delay time to ensure that the spindle reaches the rated speed.(2) during tool retraction, if it is a hand ground thread tool, because the tool cannot be grinded symmetrically, reverse tool retraction cannot be adopted. The spindle orientation must be adopted, the tool moves radially, and then the tool retraction.(3) the manufacturing of the cutter bar must be accurate, especially the position of the cutter slot must be consistent. If it is inconsistent, multiple cutter bars cannot be used for processing, otherwise it will cause disorderly buckle.
(4) even if it is a very fine buckle, it cannot be picked with one knife, otherwise it will cause tooth loss and poor surface roughness. At least two knives shall be divided.(5) the processing efficiency is low, which is only applicable to single piece, small batch, special pitch thread and no corresponding tool.3.3 specific procedures

There are instances where we are asked to CNC machine parts, product or a prototype that are either hard to machine, too complicated geometrically, will not yield great accuracy or simply cannot be machined. What do we do? For these scenarios, 3D printing the parts can be a great solution. So why not substitute CNC machining with 3D printing every single time? Well, there are advantages and disadvantages, pros and cons for each machine and process. So, which one is best for our needs? In which circumstances do we prefer one over the other? And is there another solution that might combine these two together to create a combo part? The basic difference between the two processes is that with CNC machining we are reducing material as we start with a foam block for example, carving it away; while with 3D printing we are layering on and adding material until we receive the final product, therefore called additive manufacturing. The 3D printer uses the same materials that make up the part it is creating, for instance ABS PLA and nylon, but it cannot switch between materials, whereas in CNC machining we can use several types of materials, often adding additional materials at the end. However, machining can be messy - Sometimes we need to use a dust collector while operating a CNC router machine to catch all that excess made in the drilling, carving and milling process, while there is less waste material produces in printing and the whole process is less noisy. CNC machining can be more precise providing more accuracy because the machines have a higher tolerance for heat. It can also result in a much smoother polished surface finish given the materials to be machined. 3D printers can actually distort a part, bend and warp if using too much heat on the layered material, so if exceptional smoothness is required the 3D printing will fall short. 3D printing is generally an easier more convenient process and not as labor-intense as CNC machining, since with machining we need to program, write a G-Code, set up different tools and speed, decide on cutting path and clean up after. However, the part size plays a role, as larger parts take longer to be printed adding layer by layer. Overall, 3D printing can assist in some cases of prototyping of high geometric complexity where the router tool cannot reach inside the shape. 3D printers can only use the area of the printer bed itself to fabricate the parts. Therefore, if large scale parts are needed they might not be able to fit in there. It is also not recommended for mass production as the materials are much more expensive and take much more time to fabricate. Therefore, 3D printing is more appropriate and more cost-effective for low volume production. CNC machining can rarely run unattended and requires skilled operator, while with 3D printing we can easily run the process unsupervised and it requires minimal training for its operator. However, CNC machining is an older practice (started in the 40's) and currently still has a stronger position in the manufacturing industry. 3D printing is relatively new and still evolving to be more useful and adaptable and still cannot be a full replacement for machining. In summary, the most appropriate technique to use will be determined by the material, geometric complexity, manufacturing volume and our budget. As a general guidance, we would switch to 3D printing mostly if fast turn-around in critical, if the part is too complex to be machined, for prototyping small volumes and if we need to use certain materials that cannot be easily machined. Having named most of the pros and cons for each technique, apparently there is a good solution that actually combines the two together to create one part. We often machine parts of the desired product using a CNC router, while fabricating other small yet more complex parts in the 3D printer, we then glue all parts together to make one unit. Another option is then to coat all glued combined parts with hard coat such as Polyurea, Styrospray or epoxy, then smooth and paint them. That way we both save time using the CNC machining process as well as being able to manufacture more complex parts combining the best of the two worlds together to create a hybrid.
