A methodical introduction to CNC terminology, a discussion of the differences between standards, an examination of the practical impacts, and some suggestions for businesses are provided in this article by way of the following key points:The initial widespread dissemination of the CNC standard names and backgrounds in China, the United States of America, and EuropeAn examination of the nuances that set apart the three most prominent standards for comparisonCertification according to the criteria established by CNCDiscussion on the specific effects that the implementation of the various standards has, both individually and collectively.





The initial widespread dissemination of the CNC standard names and backgrounds in China, the United States of America, and EuropeThe standard for computer numerical control (CNC) in China is called Interfaces for Numerically Controlled Machine Tool Drives and Motors, and its official designation is GB/T 15173. This standard lays out the requirements that must be satisfied by CNC machine tools with regard to their electrical interfaces, mechanical interfaces, and other interfaces as well. The EIA RS-274, also known as the EIA Recommended Standard for Control Data Exchange Between Numerically Controlled Machine Tools, is the standard for CNC in the United States. Another name for this standard is the EIA Recommended Standard for Control Data Exchange Between Numerically Controlled Machine Tools.


The stipulation of command code formats, transmission protocols, and other related matters for CNC systems are the primary focuses of this standard

1. The European standard for numerically controlled machine tools, numerically controlled systems, and user interfaces is DIN 66025, which is also known as Format for the Exchange of Dialogue Mode Data For Numerically Controlled Machine Tools, Numerically Controlled Systems, and User Interfaces

2. This standard establishes the universal ISO CNC code format that is utilized all over Europe

3. This format is used extensively in the automotive industry

4. An examination of the nuances that set apart the three most prominent standards for comparisonThere is a generally high level of compatibility between the three standards, despite the fact that there are some differences in the implementation of the more fine-grained details between them

5. While the Chinese standard provides extensive provisions for domestic machine tool interfacing, the European standard places a greater emphasis on the principle of universal applicability

6. In contrast, the standard followed in the United States places a greater emphasis on the software code level

7. In general, computer numerical control (CNC) systems can be utilized for international business if they are compliant with any of the standards



Certification according to the criteria established by CNCThe process of obtaining certification in China for CNC productsIn China, the implementation of a system of mandatory product certification is currently taking place. die casting mold is mandatory for CNC systems to have their conformance to safety and electromagnetic compatibility (EMC) standards certified by organizations that have been granted accreditation by the CNCA before they can be marketed, sold, or exported. The certification process requires both the testing of prototypes and the inspection of manufacturing facilities. The GB/T 30041 series is the primary set of certification standards that are currently in use. Certification is required in order to work with CNC in the United States. Even though the United States does not have any mandatory requirements for CNC product certification, any product that is sold in the country or that is imported into the country must comply with US industry standards such as UL, NFPA, and NEC. This is the case regardless of whether or not the United States has any mandatory requirements for die casting mold. The vast majority of situations call for UL certification, with UL 508 being used for electrical equipment and UL 1998 being used for software.

In order for programs to be run on different controllers, the source code first needs to be converted. Definitions of different kinds of coordinate systemsThe XYZ coordinate system is the one that is utilized most frequently in both the United States of America and Europe. On the other hand, the ZXY system is the one that is utilized most frequently in China. Because of this, the directional commands in the programs may not be understood as well as they could be. When working with coordinates, it is essential to take into consideration the various coordinate systems that are available. Programming syntax While standards in the United States and Europe connect commands with letters, GB codes in China connect multi-byte commands with hyphens. This is in contrast to the standards in the United States and Europe. China makes use of the GB code system. When describing the same functions, various programming standards employ different collections of declarative statements. Formats for instrument compensation toolsT codes are used to indicate compensation numbers in China, in contrast to the H codes that are used in the United States and Europe.

Converting files from one format to another is essential for error prevention whenever multiple formats are utilized simultaneously. Specifications for user interfacesThe Chinese standards define the pin layouts and wire orders for a variety of interfaces in a clear and concise manner. On the other hand, these standards differ from those used in other countries, which can have an impact on the connectivity compatibility of devices. Conversion calculations are required whenever the parameter settings are applied because different nations use different units for parameters such as speed and feed rate. There are also subtle differences between the countries in the safety requirements for machine tools, such as the grounding, isolation, and labeling requirements. These distinctions can be observed in the various machine tools. In addition to being application-oriented and pragmatic, the aforementioned key points provide a comprehensive overview of the various national differences in CNC standards.
