CNC control system is an important part of high speed machining center, which determines the speed, precision and surface quality of machine tool to a great extent. Therefore, the performance of the CNC system is of special significance for the high-speed machine tool with the free surface of the die.
High precision machining of freeform surface, the tool path is composed of micro segment of line and arc caused by large parts of the program, the flow of data to storage and processing, the machine tool control system so the block processing time is an important indicator to determine CNC control system efficiency. At present, the processing time of the program segment of the high grade CNC control system is generally up to 0.5ms, while the processing time of the individual numerical control system has been shortened to 0.2 ~ 0.4ms.
It is applied and can work with nanometer resolution to obtain high machining precision and surface quality in high speed machining.
At present, the high-end CNC system can also be connected with CAD/CAM systems of different manufacturers. Data is transmitted to the control system from CAD/CAM system at high speed through Ethernet. CAD/CAM integrated into the control system, to a large extent, can make the machining of the complex contour of the mold achieve good results, and make a very important contribution to shortening the adjustment time and programming time. The modern CNC CNC system for high speed machining of die and mould has Nurbs and spline interpolation functions besides the very short processing time needed to ensure high-speed feed speed.
