The system configuration of CNC machine has nearly a thousand parameters to be set. These parameters are set correctly or not directly affect the use of CNC machine tools and their performance. It has been proved that the parameter setting about the CNC machine can bring much convenience to deal with troubleshooting and maintenance of CNC machine, reduce troubleshooting time and improve machine utilization. But for some parameters such as pitch compensation, position of reference points, these parameters settings are not in the same way in different machine. If parts of these parameters or all of these are lost, its unable to restore the precision of the CNC machine. It will bring great losses to the manufacturing enterprise. So the data of protection is particularly critical. This paper describes the function and principle about the machine data protection, and presents the method and step of data backup and recovery for the CNC machine with the typical CNC system, such as FANUC, Siemens and Huazhong CNC system.

To overcome some shortcomings of the linear Acc/Dec approach and the traditional S-curve Acc/Dec method, a novel velocity planning approach is proposed for CNC machine tools in this paper. The velocity planning model based on moving average technology is structured. The presented approach is used to make velocity planning for the CNC system. Comparing with the linear Acc/Dec algorithm, the presented method greatly improves motional smoothness of the linear Acc/Dec approach and reduces the complexity of the traditional S-curve Acc/Dec algorithm, which is more suitable for high-speed and high-precision CNC machine tools. The proposed approach is tested by simulation and experimentation. Simulation and experimental results have shown that the proposed method can significantly improve the motional smoothness and consumes less resource and shortens processing time for the CNC system.

CNC machine tools tend to build their coordinate systems according to the categories of returning reference points. Due to their detecting structures and principles, four distinct styles of reference point returning come into being, that is, Reference Point Establishment based on Incremental Encoder and Mechanical Block, Datum-point style Returning Reference point, Reference Point Returning with Incremental Encoder and no Mechanical Block, Percussion Reference Point Returning based on Absolute Encoder. In this paper, the author tries to probe into the basic requirement, working process and design requirement of the four styles.

The Core

CNC system is the core of CNC Machine Tools, reliability of CNC system is decided in its design stage. Design stage of CNC system can be divided into software design and hardware design. In software design, there is not perfect theories to follow, so every factors should be considered, different factors should have different measures; In hardware design, some methods and experience can be used for reference, and improve these methods and experience. In order to improve the CNC system reliability fundamentality, CNC system need stability base, measures should be done from design stage.

The analysis shows that the development of programming tools for CNC systems is focused on the development of new machine canned cycles, including those for processing complicated surfaces, their complex combinations or complex mutual arrangement, but does not concern such issues as the universalization of cycle parameters. This does not make it impossible to transfer control programs from one CNC system to another. This work proposes an approach to the development of tools for creating universal cycles of typical technological transitions of machining on machines with different CNC systems.
