数控车床仿真系统中指令解释器的设计与实现

Design and Implementation of Command Interpreter in Numerical Control Lathe Simulation System

针对车床仿真系统指令解释器的瓶颈问题,开发设计一种快速、高效、合理的指令解释器,并给出了指令解释器的分析设计过程,结合更合理的指令存储模式,实现了快速有效的词法、语法、语义检查和高精度直线型和圆弧型的解释过程.实验结果表明,该解释器指导的车床仿真系统在执行速率、切割精确度及合理性上都有一定改进.

In view of command interpreter often becoming the bottleneck of the CNC simulation system,the authors introduced the detail process of developing a rapid,efficient,reasonable command interpreter,proposed a more reasonable instruction storage mode,realized the fast and effective lexical,syntax,semantics checking process,and high-precision implementation algorithm for linear,circular explanation process.The experiment shows that the simulation system has been improved in execute speed,incise accurate and also rationality.
