CNC machine tool processing is a very important processing mode in our production industry. In the market, this processing industry occupies a very important part of the middle. It is specially processed for some curved surface parts that are relatively difficult to process. To a certain extent so that it can be reasonably matched with the ontology. This technology is mainly used in the aerospace field, aviation field and military field, etc., all of which have certain authority. In general, five-axis CNC machining can process different sides of the workpiece without changing the position of the workpiece on the machine tool, which can greatly improve the processing efficiency of prismatic parts. The processing steps of three-coordinate measuring machine to measure coaxiality are a method we often use in the process of processing, but sometimes there will be large errors in measurement results and poor repeatability, to a certain extent. It cannot truly reflect the real coaxiality error of the part. So how can we reduce the coaxiality error? Next, let me give you a brief introduction.
1. Establish a common axis as a reference axis. In general, we can use the method of establishing a common axis as a reference axis. This method is more crystallized for the evaluation results than the actual use. The specific operation is actually to measure the mid-section on the reference cylinder and the measured cylinder, then calculate the coaxiality of the reference cylinder and the measured cylinder with respect to the common axis, and then take the difference.
2. Increase the distance between the reference sections. I wonder if you have thought about it. If you increase the distance between the first section and the second section, the proportion of error interference will decrease accordingly. If the datum is long enough and the datum section is adjacent to the tested section, the error caused can be negligibly small.
3. It is a good choice to use a three-coordinate measuring machine to measure the coaxiality by approximating the straightness. However, the axis offset has a great influence on the assembly of the workpiece, and the measurement of the axis offset is actually the straightness of the line connecting the axes. The method works better, and it is easy to make a comprehensive gauge to verify the accuracy of the method.
To sum up, the above is my preliminary understanding of this product. If you want to know more, please call our five-axis linkage cnc processing manufacturer, or you can click the corresponding link in the article to view more relevant knowledge.
