Problems solved by technology

However, no matter which method is used, it is calculated point by point according to the order. The calculation speed of such calculation can only depend on the calculation speed of the computer itself. Obviously, due to the limitation of technical conditions and cost, the calculation speed of the computer is Limited, which restricts the improvement of high-speed and high-precision CNC machining

Description

technical field [0001] The invention relates to a computing device for CNC running data. Background technique [0002] CNC machining is one of the basic processes of contemporary mechanical manufacturing. CNC machining requires the help of CNC machine tools. The CNC system is one of the core components of the CNC machine tool. At present, CNC numerical control is the only form of modern numerical control system. High-speed and high-precision CNC system is the fundamental guarantee for improving processing efficiency and quality. The new reconfigurable technology represented by field programmable gate array FPGA not only changes the traditional CNC interpolation calculation process but also changes its calculation mode. However, no matter which method is used, it is calculated point by point according to the order. The calculation speed of such calculation can only depend on the calculation speed of the computer itself. Obviously, due to the limitation of technical condit...
