Various mechanical equipment and metal tools form the foundation of modern industrial construction and development in our country. Their performance and quality are largely determined by the processing accuracy of metal parts. However, from the perspective of current production practice, the processing accuracy of metal parts is still affected by various factors, such as cutting tools, temperature, stress, etc. In this regard, in order to maximize the processing quality of metal parts and ensure that they fully play their value role in equipment and tools, it is necessary to conduct in-depth research and discussion on the impact of mechanical processing technology on the processing of metal parts, and actively explore feasible paths to reduce the occurrence probability and severity of negative effects.
The significance of controlling the influence of mechanical processing technology on the processing of metal parts
The processing quality of metal parts involves various indicators, such as surface roughness, shape and form, specifications and dimensions. In modern mechanical manufacturing, these indicators all have high-precision and standardized processing requirements. Any abnormal change in any one of these indicators will seriously reduce the functionality and adaptability of metal parts in mechanical structures. From a production perspective, the application level of mechanical processing technology has a direct impact on the processing quality of metal parts. If the technology application is not in place, metal parts are likely to have defects such as excessively high surface roughness, deformation under force, and dimensional errors under abnormal working conditions.
At the same time, the wear resistance, corrosion resistance and other properties of the metal parts will also be negatively affected, which in turn further reduces their practical value. To achieve comprehensive compliance with the quality standards of metal parts and to ensure the mechanical manufacturing efficiency while reducing resource consumption, it is necessary to take a technical approach and conduct comprehensive control over the processing impacts of metal parts.
The main manifestations of the influence of mechanical processing technology on the processing of metal parts
- The external influence of mechanical processing technology on the processing of metal parts
In the process of production and processing, the external influence of mechanical processing technology on the processing of metal parts mainly manifests in the following aspects:
* Force load influence. In the context of mechanical processing, metal parts are subject to the combined effects of various forces, such as the clamping force of machine tools, the cutting force of cutting tools, the compressive force of fixed components, the impact force and frictional force of deburring devices, etc. Mechanical processing has the characteristics of long cycles and strong continuity, and involves a large number of process steps, which means that metal parts need to remain in a complex force state for a long time. Under this circumstance, if any one or more forces experience abnormal fluctuations, or if the actual force level of the metal parts exceeds their load threshold, it is very likely to cause the metal parts to deform, crack, or wear due to uneven force distribution.
* Residual stress influence. In mechanical processing, some forces such as contraction force, expansion force, and pulling force still exert an effect on metal parts after the completion of the processing steps and the removal of the force source. This phenomenon is known as residual stress. Based on this, if metal parts carrying residual stress are directly put into the subsequent processing steps, the residual stress will superimpose with the processing stress, thereby having a serious negative impact on the force structure, performance quality, and other aspects of the metal parts, such as reducing the rigidity of the parts, weakening the fatigue strength of the parts, and causing secondary deformation of the parts.
* Temperature influence. In mechanical processing, processes such as injection molding and welding have the characteristic of high-temperature operations, and cutting, grinding and other processing operations also involve a certain amount of heat release. As a result, if the material of the metal parts has poor heat resistance, thermal deformation effects are likely to occur, and even local melting problems may arise, which will further lead to a significant reduction in the dimensional accuracy and usage quality of the parts. On this basis, if friction generates heat during the cold treatment processing of metal parts, a significant temperature difference will form between the internal structure and the friction surface. Once the temperature difference becomes too large and causes uneven heat stress distribution in the metal parts, the metal parts will undergo severe deformation under the influence of expansion and contraction, and the processing effect will be significantly deteriorated.
- The influence of mechanical processing technology on the internal structure of metal parts processing
Mechanical processing has the characteristic of fixed production, meaning that the processing activities will continue to operate under relatively fixed and preset conditions, thus ensuring that the metal parts of the same batch are produced completely in accordance with the process flow. From a positive perspective, this processing method largely guarantees the standardization and efficiency of the part processing.
However, from another perspective, if the preset process flow and facility conditions themselves have inherent problems, the processing quality of the metal parts will definitely be fundamentally affected. For instance, if the relevant personnel are negligent when setting up the machine tools and installing the cutting tools, causing the tools to be loose, unstable or misaligned, it will result in the tools being unable to move according to the standard cutting angle and cutting path during mechanical processing. The processing accuracy of the metal parts will be seriously insufficient and it will be difficult to achieve the expected completion quality.
For instance, if mechanical processing equipment is constantly operating under high-load conditions and without an effective maintenance and fault repair mechanism to support it, its components are bound to experience certain wear and tear during operation. In this situation, if the wear and tear becomes too severe, the functionality of the components will also weaken, thereby leading to problems such as low processing accuracy and numerous potential hazards.
- Analysis of the Causes of the Impact of Mechanical Processing Technology on Metal Part Processing
Based on industry experience, there are numerous factors that can negatively impact the processing quality of metal parts through mechanical processing techniques. Specifically:
** The technical accuracy is insufficient and the facility configuration is not complete.
** The selection of processing tools is inappropriate.
** Mechanical processing equipment mainly relies on electromechanical control and is equipped with specific control programs.
** The negative effects that metal parts suffer during mechanical processing usually have the characteristics of gradual accumulation and intensification.
** The processing technology is outdated.
In conclusion, in the application of mechanical processing technology, the processing quality of metal parts is influenced by various internal and external factors. These influences are related to multiple aspects such as equipment configuration, tool installation, and control mechanisms. Based on this, in the practice of optimizing mechanical processing technology and improving the processing quality of parts, it is necessary to adhere to the principles of comprehensiveness and dynamics to ensure the maximum elimination of negative impacts and achieve high-quality and stable processing and production of metal parts.
