Kaiao-RPRT specializes in the creation and processing of thin-walled parts or metal thermoplastic components with walls thinner than 1 mm. These components are renowned for their small size, minimal material energy usage, and lightweight design.
Because of these beneficial characteristics, thin-walled parts made with Kaiao-RPRT are widely used in various industrial applications. However, a number of important variables, like CNC tooling and CNC machining procedures, are involved in the R&D and processing of these parts, which might affect the manufacturing quality. Addressing these factors is imperative to ensure that the parts fulfil the exacting standards and needs of the market.
Factors affecting machining accuracy of thin-walled parts. Thin-walled parts with lightweight processes have superior performance, but ensuring machining accuracy is also challenging. Because of their lack of rigidity, thin-walled parts are easy to deform in CNC machining, which can lead to direct damage to the parts.
In this regard, CNC machining of thin-walled parts is one of the important research directions in CNC machining research, which is of great significance for developing the CNC machining industry. To ensure the ideal effect of thin-walled parts processing and improve machining accuracy, it is necessary to analyze the relevant influencing factors and grasp the relevant precision influencing factors accurately.
Machining accuracy requires the corresponding parts' processing in terms of size, shape, location of the geometric parameters, and specific requirements to be completely consistent to ensure that the workpiece's machining accuracy is in line with the quality standard requirements. The current impact of thin-walled parts on the influence of factors is machine accuracy, stiffness, thermal deformation, stress, and process impact.
Related thin-walled parts in the CNC machining, cutting the workpiece because of high-speed friction operation, will inevitably cause local overheating, coupled with the role of stress, which can easily lead to deformation of the workpiece, increasing the machining accuracy error.
In this regard, it is necessary to do a good job of temperature control, using high-pressure coolant to cool the machining temperature of the workpiece during machining to reduce the error to an acceptable range.
The force in the fixture and tool usually causes force bending. Studies have shown that the error caused by cutting force when machining the workpiece is greater than the error caused by pressure, so the problem of error in the milling process of thin-walled parts will be more severe and should be avoided to reduce the adverse effects of processing this machining process.
In the current manufacturing and processing of thin-walled parts, the tool must effectively contact the spindle. It must strictly control the positioning accuracy, so it is necessary to use a tool that can withstand and effectively control errors and errors.
In addition, using the relevant tool in continuous machining inevitably causes wear and tear, and the resulting error will also cause the deformation of thin-walled parts. The structure of the tool will also affect the machining quality. In CNC machining, the tool consists of a clamping part and a working part, and the clamping part can be divided into two types: hole and threaded.
Among them, the bore tool is mainly used for assembling internal holes. The use of CNC machine tools for processing related thin-walled parts is affected by many external and internal factors, such as hardness, toughness, and tool life, which directly affect machining quality and efficiency.
Some CNC Machining service manufacturers in the processing of thin-walled parts will find it difficult; this is because, in special processing, the long-term continuous operation may lead to the local or whole body temperature of the mechanical equipment, the pressure on the relevant system, coupled with the thin-walled parts itself is a low thickness, easy to deform, coupled with the role of thermal factors, is not conducive to improving the machining accuracy.
In the process of processing and heating, some changes will occur in mechanical operation, which will increase the overall changes in mechanical operation, the need for the relevant processing personnel to carry out the necessary cooling treatment of processing, overheating phenomena such as CNC machine tools and other processing equipment timely inspection and treatment to avoid local deformation problems.
The birth of the CNC milling machine significantly improved the production level and quality of industrial processing. Since then, CNC technology has attracted widespread attention, and its application range has been expanding. CNC machine tools have significant differences in control systems and mechanical structures compared to traditional machine tools.
By analyzing the impact of CNC programming on the machining of thin-walled parts from the perspective of CNC programming, we can see the basic principles of selecting the starting point of programming and understand its impact on the accuracy of thin-walled parts. Machining based on program data also impacts machining accuracy.
This is mainly due to differences in the calculation of unknown programming nodes. From the perspective of the machining system, the machining system is the main content of CNC programming, which will significantly affect the machining accuracy and efficiency.
In the thin-walled parts of the CNC machining of the pre-processing, the need for parts of the CNC machining process quality analysis, taking into account the corresponding process by some thin-walled parts of their structural dimensions and high-precision quality requirements and other factors, coupled with some of the thin-walled parts of their structural rigidity is not enough, prone to deformation, which results in thin-walled parts in the CNC machining of the relevant quality requirements are more stringent.
In carrying out the CNC machining of thin-walled parts, the use of CNC cutting and processing equipment for parts is critical to ensure the quality of CNC machining of thin-walled parts. The choice of tools is also essential. In product selection and application, the user needs to analyze the all-around detailed analysis of the specific working model of the tool used, parts and technical indicators, and other factors to ensure that the use of the tool work progress, speed, size, and so on to meet the process requirements, thereby enhancing the processing efficiency and stability.
Simulation-based CNC machining process quality improvement. We can use simulation CNC machining to improve the process, using the KU = F theoretical formula for thin-walled parts for processing, where K represents the overall strength matrix of the parts, and F represents the load matrix borne by the parts processing.
U represents the specific deformation of the part being machined. The formula's interpretation shows that F and U are negatively correlated; in this regard, to improve the thin-walled parts of the CNC machining process, the K value needs to be adjusted appropriately to effectively reduce the deformation of thin-walled parts and enhance the quality of its processing.
In selecting thin-walled parts processing material, one needs to ensure that the strength of the raw material meets the requirements based on the premise that the primary raw material remains unchanged. One can also choose to increase the relevant filler to strengthen the material strength. Once the parts processing work is completed, the parts can be removed, and the deformation of thin-walled parts effectively alleviates the problems and ensures the quality of processing.
Parts of their own stiffness factors for processing accuracy have a greater impact. A reasonable choice of clamping methods and processes is very necessary to enhance the rigidity of thin-walled parts processing, which has a positive effect on the protection of thin-walled parts processing overall accuracy and effectiveness.
In the processing, you also need to ensure that the overall processing fastness, for easy deformation of the parts, does a good job of quality protection measures to reduce the impact of unfavorable factors. In addition, it is best to use professional clamping, such as construction ring, expansion sleeve, etc. The relevant measures can promote the parts processing accuracy and rigidity enhancement.
In the CNC machining of thin-walled parts, when the number of workpieces processed by the tool reaches a certain value, the tool can be changed in a timely manner, controlling the error caused by tool wear.
Only in the processing of the controllable error can comprehensive control be carried out to avoid an overall processing error increase. In addition, in parts processing, specific processing workpiece process requirements and reasonable tool selection are also needed.
The processing accuracy of thin-walled parts will be affected by the product progress and mold structure requirements. To ensure that the overall machining accuracy of the product meets the requirements, reasonable tool selection is needed.
In the structure of the parts, the degree of coordination of the upper and lower mold also has strict requirements, which need to ensure that the mold parts meet appropriate CNC machining parts accuracy standards. Based on the needs of mass production, ensure that the tool material meets the requirements and that toughness, stiffness, and hardness meet the requirements with a certain degree of wear resistance.
Many elements, such as the workpiece process, instrument error, thermal factors, and CNC machining technology, affect the specific CNC machining process when processing thin-walled parts. It is crucial to base the particular processing on simulation and actual CNC machining process quality improvement to guarantee the benefits and quality of CNC machining of thin-walled parts. Enhancing the clamping of pieces, choosing the best tools, and fine-tuning cutting parameters are essential. Kaiao-RPRT is dedicated to implementing these safeguards to guarantee the best possible processing quality and accuracy.
