数控雕刻机常用齿轮齿条进给伺服传动，存在无限不循环小数π引起脉冲当量误差的问题。在分析已有解决方案优缺点的基础上，提出利用355/113代替π，同时减速部分中步进电机采用细分驱动并搭配使用齿轮减速机构的方案，降低了进给伺服系统制造精度的要求，并减小了π因子引起的误差。

CNC engraving machine often use gear-rack feed servo system to transmit,and there are pulse equivalent error dued to infinite non-repeating decimal π.In this paper, we analyzed the advantages and disadvantages of previous solutions,and based on the analysis, we used 355/1 13 to replace π.At the same time,we used subdivided driving stepper motor with gear deceleration collocation,making the manufacturing precision of servo system is feasi-ble,and reducing the error caused by the factor of π.
