一种位插补数据生成算法以及位插补误差分析

Data Generating Algorithm of Bit Pattern Interpolation and Error Analyzing of Bit Pattern Interpolation

位模式插补本身不产生特定的运动控制,只是根据上位机下传的位模式数据进行脉冲的发送,整个过程的运动控制以及插补算法误差都来自上位机位模式数据的生成过程.因此,本文对自由曲线位模式插补数据的生成进行了研究并提出一种误差可控的位模式数据生成算法.最后通过实例对算法进行了验证并进行了误差分析.验证结果表明,该算法可行而且有效.

Bit pattern interpolation can＇t generate motion control and only transmits pulses according to the bit pattern data sent by the host computer and both motion control and the algorithm error come from the generating of the bit pattern data. So the generating of the bit pattern data is researched and an error-controllable data generating algorithm of bit pattern interpolation of free-form curves is proposed in this paper. An example is used to testify the validity of the algorithm and the analyzing of the error is carried out.
