Aluminum alloy refers to non-ferrous metal structural material with a mass fraction below 0.5% and above 0.2%, widely used in the industry. CNC machining of aluminum alloy is a process method for effectively machining aluminum alloy parts on CNC machine tools, which can meet the requirements of aluminum alloy machining for high precision. Aluminum alloy thin wall has the basic characteristics of a complex shape, and most of the shape is curved, which puts forward high requirements on the mutual shape tolerance of the surface, resulting in a very high difficulty factor for its processing. The CNC machining process of aluminum alloy thin walls must be optimized to improve accuracy of CNC machining of aluminum alloy thin walls. By improving the stability and safety of the CNC machining process of aluminum alloy thin wall, the problem mentioned above of the difficulty of CNC machining of aluminum alloy thin wall can be effectively solved.

Due to the NURBS curve equation’s interpolation principle in the quenching process of aluminum thin-wall CNC machining, the quenching process of aluminum thin-wall CNC machining needs to be optimized using aging interpolation. The specific process of aging interpolation for quenching thin-walled CNC machining of aluminum alloy is.
First, determine the type value point of the quenching aging interpolation NURBS curve of aluminum thin-wall CNC machining and the programming of the weight factor; then calculate the coefficient matrix by obtaining the node vector; on this basis, control the quenching vertex of aluminum thin-wall CNC machining by controlling the vertex weight factor; then get the NURBS interpolation curve to start CNC machining. In this process, the quenching aging interpolation error of aluminum alloy thin wall CNC machining must be analyzed to achieve the purpose of aluminum alloy thin wall precision CNC machining.
2 Calculation of aluminum alloy thin wall CNC milling around the standard size of the allowable error
CNC milling around is a key process in the CNC machining process of aluminum alloy thin wall; this paper is optimized by using standard size measurements of aluminum alloy thin wall parts, obtaining the reference size of the bearing of aluminum alloy thin wall parts, presenting the data to the display, adjusting the gray value of the data, mapping it to a new range, highlighting some of the feature values in the edge of the bearing, identifying the raw image grayscale, and equalizing the data in the image so that The edge data histogram presents a consistent direction. As the data in the process of dimensional measurement will be affected by a variety of external factors, the actual collection of data in the sensitive element parts affected by interference will exist internal noise, so the data filtering method is invoked to implement median filtering processing of the data, and extract the standard data set of aluminum alloy thin-walled parts dimensions after filtering processing.

The main purpose of CNC milling through-hole is to determine the final shape of thin-walled aluminum alloy CNC machining, and CNC milling through-hole step length can directly affect the processing results. Combined with the study of the traditional CNC machining process of aluminum alloy thin wall, it is known that the main factors affecting the step length of CNC milling through hole include: the driving curve, driving point, internal tolerance, and external tolerance. The calculation expression of the step length can accurately determine the through-hole step length of CNC thin-walled aluminum alloy milling.
