Collet turning and milling composite processing technology is an advanced processing method that integrates turning and milling. It can complete the processing of copper parts with complex shapes and high precision requirements in one clamping through the precise control of CNC machine tools. The advantage of this technology is that it reduces the error accumulation caused by multiple clamping, improves processing efficiency and accuracy, and reduces production costs.
In the chuck turning and milling composite processing, accurate calculation of the cutting parameters of each process is the key to ensuring processing accuracy. Cutting parameters include tool path, feed speed, spindle speed, etc., which directly determine the key factors such as cutting force, cutting temperature, surface roughness, etc. in the processing process, thereby affecting the processing accuracy and product quality.
Tool path planning: The tool path is the movement trajectory of the tool relative to the workpiece during the cutting process. Reasonable tool path planning can reduce the empty stroke during the cutting process, improve processing efficiency, avoid collision between the tool and the workpiece, and protect the safety of the tool and the workpiece. In the chuck turning and milling composite processing, due to the complex processing shape, tool path planning is particularly critical.
Feed speed setting: Feed speed refers to the speed of the tool relative to the workpiece during the cutting process. The size of the feed speed directly affects the cutting force, cutting temperature and surface roughness. In the chuck turning and milling composite processing, the feed speed needs to be reasonably set according to factors such as the hardness of the copper material, cutting depth, and tool material to ensure the stability and efficiency of the processing process.
Spindle speed adjustment: Spindle speed refers to the rotation speed of the spindle during the cutting process. The high and low spindle speed directly affects the cutting force and cutting temperature, and then affects the processing accuracy and tool life. In the chuck turning and milling composite processing, the spindle speed needs to be reasonably adjusted according to the processing requirements and tool characteristics to achieve the best cutting effect.
In order to ensure the high-precision customization of copper parts in the chuck turning and milling composite processing, it is necessary to use scientific methods to accurately calculate the cutting parameters.
Theoretical calculation and simulation analysis: First, based on the principles of cutting mechanics and thermodynamics, the cutting parameters are theoretically calculated to obtain a preliminary cutting parameter range. Then, using computer simulation technology, the cutting process is simulated and analyzed to evaluate the cutting force, cutting temperature, surface roughness and other indicators under different cutting parameters, and further optimize the cutting parameters.
Experimental verification and optimization: Based on theoretical calculation and simulation analysis, cutting experimental verification is carried out. By comparing the processing effects under different cutting parameters, the rationality and feasibility of the cutting parameters are evaluated. According to the experimental results, the cutting parameters are fine-tuned and optimized to achieve the best processing effect.
Intelligent cutting parameter optimization: With the development of artificial intelligence and big data technology, intelligent cutting parameter optimization has become possible. By collecting and analyzing a large amount of cutting experimental data, a mathematical model between cutting parameters and processing effects is established. Then, the cutting parameters are optimized using intelligent algorithms to achieve intelligent setting and adjustment of cutting parameters.
The precise calculation of cutting parameters has an important impact on the high-precision customization of copper parts in chuck turning and milling composite processing.
Improve processing accuracy: Accurate cutting parameters can reduce the accumulation of errors in the cutting process and improve processing accuracy. By optimizing cutting parameters such as tool path, feed speed and spindle speed, it can ensure that the copper parts maintain stable shape and dimensional accuracy during processing.
Improve product quality: Accurate cutting parameters can control the cutting force and cutting temperature in the cutting process, reduce thermal deformation and surface damage of the workpiece, and improve surface roughness and finish. At the same time, reasonable cutting parameters can also extend tool life and reduce the impact of tool wear on machining accuracy, thereby improving product quality.
Reduce production costs: Accurate cutting parameters can reduce waste and loss in the cutting process, improve machining efficiency and material utilization. At the same time, by optimizing cutting parameters, it is also possible to reduce cutting force and cutting temperature, reduce machine tool wear and energy consumption, and thus reduce production costs.
Chuck turning and milling composite processing technology has broad application prospects in the field of customized copper parts processing due to its high efficiency and high precision. However, to ensure high-precision customization of copper parts, it is necessary to accurately calculate the cutting parameters of each process. Through theoretical calculation, simulation analysis, experimental verification and intelligent optimization, the precise control and optimization of cutting parameters can be achieved.
