摘　　要：针对逐点比较法、数字积分法等存在的加工精度低的问题,提出了一种新的插补算法——最小偏差法。介绍了最小偏差法的插补原理和插补算法公式。在QuartusII开发平台上,运用硬件描述语言Verilog HDL语言设计了最小偏差法直线插补程序,选用FPGA器件实现了最小偏差法插补器。Due to the point by point comparison method, numerical integral method, etc, there is a low processing precision of defects. This paper proposes a new interpolation algorithm--the minimum deviation method. This method can improve the machining precision of workpiece, make up the defects of the low accuracy. Moreover, this paper details the principle of minimum deviation method of interpolation and the interpolation formula. On the QuartusII development platform, this paper uses the hardware description language Verilog HDL to design the minimum deviation method of linear interpolation program and chooses FPGA device hardening to achieve the minimum deviation method of interpolation. The interpolation device combined with ARM processor to set into a high speed and high precision CNC system.
