(1) the influence of tool wear factors on the machining accuracy of precision cnc turning parts In the process of processing, the tool after a long time to use, there will be different degrees of wear. Cutting tool wear to a certain extent, it will affect the effect of subsequent processing. Tool wear will lead to changes in the diameter of the precision cnc turning parts in the process of machining, which is not conducive to the product to meet the corresponding production standards. Therefore, in view of the problem of tool wear, the operator should be combined with the precision cnc turning parts material properties and its diameter requirements, in the process of setting parameters. In general, the operator should input the opposite value in the tool wear control system, to ensure that the precision cnc turning parts to achieve good processing effect, to ensure product quality.
(2) the influence of force and deformation factors of the process system on the machining accuracy of precision cnc turning parts
System stress deformation refers to the system is affected by various forces in the process of processing, resulting in different degrees of deformation of its structure. When this happens, the relative position of the blade and the precision cnc turning parts will change and then affect the processing effect of the precision cnc turning parts. In view of this situation, the operator needs to reinforce the precision cnc turning parts to improve the accuracy of the precision cnc turning parts processing.
(3) the influence of the thermal deformation of the process system on the machining accuracy of precision cnc turning parts
Numerical control lathe in the process of processing will produce a lot of heat, a lot of equipment and components will be deformed under the action of heat, and then affect the accuracy of precision cnc turning parts , resulting in a decline in processing accuracy. In order to reduce the influence of thermal deformation of the process system on the processing accuracy, the operator can take relevant measures to control the heat in the process of lathe by combining the properties and characteristics of the precision cnc turning parts and the processing process, and can also use relevant equipment to increase the heat dissipation capacity of the lathe itself. In the practice process, the operator can add the corresponding coolant in the relevant links, to achieve the cooling of the lathe, precision cnc turning parts and cutting tools and other equipment, to avoid the system overheating and deformation due to overheating to improve the processing accuracy. In addition, in order to control the impact of thermal deformation on the machining accuracy, the operator can also process the lathe before processing, to ensure that the lathe reaches the thermal balance state, on this basis to carry out the processing operation, which is helpful to improve the machining accuracy.
optimize the numerical control turning processing technology
In order to further improve the machining accuracy of CNC turning workpiece operators to optimize and improve the corresponding processing technology, specifically, is to pay attention to the size of the workpiece itself, shape, and the relative position of the tool and other specific elements, the design of the corresponding processing technology. In order to control the influence of the tool on the machining accuracy, the operator should monitor the use of the tool, replace the tool worn in time, to ensure the processing effect. In addition, the processing process will produce a lot of heat, will also affect the processing accuracy. The operator can choose the material that can withstand high temperature, avoid the influence of temperature change on the processing precision.
