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 involves a calculation device for CNC running data. Background technique [0002] CNC processing is one of the basic processes of contemporary machinery manufacturing.CNC machining needs to be used for CNC machine tools.CNC systems are one of the core components of CNC machine tools.At present, CNC CNC is the only form of modern CNC systems.High -speed and high -precision CNC systems are the fundamental guarantee for improving processing efficiency and quality.The new type reconstruction technology represented by the on -site programming door array FPGA not only changes the process of traditional CNC interpolation calculation, but also changes its calculation mode.However, whether it is that way, it is calculated according to the order in order. This calculation speed can only rely on the computing speed of the computer itself. Obviously, the technical conditions and cost limits, the computing speed of the computer is the computing speed of th...
