If in the process of selection, there is a factor is not selected accurately, then certainly will directly affect the final product effect, so in the selection of each one should be carefully selected, the choice of CNC system function suitability for CNC machine design selection is undoubtedly an important limiting factor. The first thing to consider is its drive capability, different CNC suppliers of solutions in the servo power range and supporting motor range is also different.
First of all, the initial screening should be done from the type of motor that can be matched, the power range. In particular, we should pay attention to whether the CNC machine tool program includes torque motors, linear motors, electric spindles are synchronous electric spindles or asynchronous electric spindles, the rated current requirements of the above motors and overload current requirements, the electric spindle speed requirements.
Five-axis machine tools need to clarify whether five-axis linkage or only requires five-sided processing, the corresponding choice of CNC system features are different. For example, for five-sided box-type processing, usually do not need RTCP, the choice is relatively large. At the same time for the five-axis function may involve CNC system suppliers in the export license, after-sales service, etc. must also be carefully considered.
Most of the CNC machines launched by machine shops, especially large and heavy CNC machines, have fully closed-loop and dual-drive requirements. In the fully closed-loop control scheme, to choose between distance encoding encoder, ordinary incremental encoder, while the CNC system should also support the corresponding feedback signal access.
CNC system networking support to become a necessary condition for the integration of production systems, for to be incorporated into a high degree of automation of the production system of CNC machine tools, it must be clear that the CNC system has the appropriate access solutions, including low-level relying on PLC input and output points directly into the CNC system built-in OPC server, in accordance with the OPC standard to open up the internal data of the CNC system to the user; in addition to production-oriented systems, the Automated online workpiece detection and tool detection is also a function that must be supported.
