The Problems in the Actual Machining Process
Introduction
With the rapid development of science and technology, the application of mechanical processing technology has become more and more extensive. As an important basis for the development of modern industry, machining technology has made great progress and has been widely used in various industries. However, in the actual machining process, some problems still exist, which are: (1) low finishing accuracy; (2) long cycle time; (3) low machining efficiency; (4) Low surface quality; (5) High energy consumption; (6) Difficulty in machining some complex projects. This article will discuss the problems mentioned above in detail.
Low Finishing Accuracy
It is difficult to obtain the exact size and shape of a part by machining. In the actual machining process, due to the inaccuracy of the machine tool, the advancement speed of the cutting tool is not easy to control, and a certain deformation is generated during the processing of the parts. In addition, the processing time is too long, the surface temperature of the parts is increased, and the size of the parts is also changed. Therefore, the machining accuracy of the parts is very low, which affects the subsequent assembly and use.
Long Cycle Time
In addition to demanding high accuracy, machining technology also requires fast processing speed. When the machining accuracy is too low, the parts need to be re-processed, which will cause the processing time to be prolonged, resulting in a longer machine cycle. In addition, the feeding speed, the feed rate and other factors also affect the cycle time of the processing.
Low Machining Efficiency
The machining efficiency usually refers to the number of machined parts of one hour, which is directly related to the productivity and production level of the enterprise. The low machining efficiency is due to the low speed of the current mechanical structure and the low speed of the cutting tool in the actual machining process. In addition, improper cutting parameters will also increase the cutting time, resulting in low machining efficiency.
Low Surface Quality
No matter what kind of workpiece is machined, its surface quality is essential, which directly affects its performance and service life. During the machining process, due to the occurrence of stomatal and rough cutting surface, the surface quality of the workpiece is not up to standard. In addition, due to the wear of the cutting tool, the sharpness of the cutting edge is gradually reduced, leading to poor surface quality.
High Energy Consumption
In the actual machining process, energy is consumed due to the transfer of mechanical energy and heat energy. Due to the emergence of thousands of sparks between the cutting tool and the workpiece during machining, the amount of heat generated is very large, making the cutting temperature very high. The high cutting temperature will not only consume a large amount of energy, but also cause the accuracy and surface quality of the workpiece to be affected.
Difficulty of Machining Complex Parts
In the actual machining process, complex parts are difficult to machine, especially inclined surfaces and curved surfaces. Due to their complex structure, it is difficult to control the cutting parameters, resulting in inaccurate machining accuracy, poor surface quality, low machining efficiency and high cost.
Conclusion
In conclusion, there are still many problems in the actual machining process, such as low finishing accuracy, long cycle time, low machining efficiency, low surface quality, high energy consumption and difficulty in machining some complex projects. In order to improve the machining technology, we must take effective measures to solve these problems. We need to pay close attention to and actively explore more scientific and advanced machining technology, so as to promote the sound development of the machining industry.
