In the realm of aviation manufacturing, high-precision five-axis linkage CNC machine tools are an absolute requirement when it comes to high-tech manufacturing equipment

In the realm of aviation manufacturing, high-precision five-axis linkage CNC machine tools are an absolute requirement when it comes to high-tech manufacturing equipment. The NASA NAS979 standard was published in 1969, and at the time of its publication, it was the only test piece standard that was generally acknowledged by the industry. However, a significant amount of experience demonstrates that the test piece is most sensitive to the geometric accuracy of the machine tool and is not at all sensitive to the dynamic accuracy of the tool. This is the case despite the fact that the test piece is not at all sensitive to the dynamic accuracy of the tool. As a direct result of this, the identification and evaluation of the accuracy zinc alloy die casting factory of five-axis machine tools is recognized as a problem on a global scale. Specifically, this is due to the fact that five-axis machine tools are becoming increasingly prevalent. However, the processing of parts by the machinery that was deemed accurate enough to pass the NAS979 standard acceptance test resulted in a significant number of quality issues. These issues arose as a result of the fact that the machinery had a significant number of quality issues.

 

New testing standards needed to be developed in order to address this problem and find a solution, and as a direct result of this need, S-shaped test pieces were developed. A simplified and abstracted version of the test piece that is in the shape of an S has been created by basing it on a summary of the primary characteristics of the surface shape of aircraft structural parts. In order to accomplish this, the machine tool must have a high dynamic performance. It is able to provide a precise illustration of the machining precision that the machine tool possesses.

 

Since the year 2000, the technical agreement for the purchase of imported machine tools has included the S-shaped test piece as a component of the agreement. In order to protect the invention right connected with the S-shaped test piece, Chengfei submitted an application China die casting manufacturer for a national invention patent as well as an application for an invention patent in the United States. At the same time, in 2008, the organization came up with the enterprise standard Machining Accuracy Test Specification for Five-Axis Linkage CNC Milling Machine in order to standardize the application of S-shaped test pieces.

 

 

The establishment of business standards and the widespread adoption of those standards have paved the way for the international standardization of test pieces arranged in an S-shaped configuration. It is necessary to separate the process of developing international standards into five distinct stages, which are the NP stage, the WD stage, the CD stage, the DIS stage, and the FDIS stage. Alongside ISO Sandviken, the meeting was organized and carried out. The committee decided to go ahead and accept the proposal. When a new international standard reaches the WD stage, that marks the point at which the standard is granted its official approval by the international community. This brand-new international standard is also the only international standard that has ever been given my nation's machine tool industry's stamp of official approval in the entire course of its long and illustrious history.

 

The international standardization of test pieces shaped like an S did not, however, proceed without any problems. At the international level, discussions were held on this topic. This is a significant node that should be taken into consideration during the process of international standardization of S-shaped test pieces. On the one hand, the company made use of the fact that it was playing on its own turf by making arrangements for the participating experts to travel to the location in question and examine the implementation of the S-shaped test piece there. The outcomes that have been achieved as a result of these actions are positive.

 

 

During the course of its progression through two significant stages, the process of international standardization of S-shaped test pieces will unavoidably come up against a great number of obstacles. Germany will be in the lead regardless of the outcome of the international effort to standardize S-shaped test pieces, just as the chief engineer of the company, Shuai Chaolin, predicted would happen. Because so many companies in the representative machine tool powerhouse have adopted the S-shaped test piece as an important standard to demonstrate the high level of technical sophistication of their five-axis machine tools, this test piece has effectively become the de facto international standard. This is because so many businesses in the representative machine tool powerhouse have adopted the test piece as an important standard to demonstrate the high level of technical sophistication of their five-axis machine tools.
