摘　　要：针对混联机床加工过程中干涉检查、空间刀具半径补偿及编程难等问题,分析了混联机床运动学逆解,提出了一种空间任意面内的刀具半径补偿方法,给出了干涉检查的判断条件。以V is-ual C++为开发环境,应用AutoCAD二次开发工具ObjectARX,建立了由NC代码驱动的混联数控机床加工仿真系统,实现了以真实加工条件为依据的加工过程实时动态模拟,预估加工的过程和结果,为检查NC代码的正确性提供了可靠的依据。Aiming at solving the problems during the processing of a hybrid machine tool, such as inference inspection, spatial cutter compensation and difficult programming, the inverse kinematic solution is analyzed, and a new cutter radius compensation algorithm in any spatial surface and a method for inference checking are presented. Based on the motion control algorithm, a machining simulation system of hybrid machine tool driven by NC codes is implemented using AutoCAD-ObjectARX and Visual C ＋ ＋. The simulatoin system can realize real-time dynamic processing imitation according to the actual cutting conditions and can predict machining process and results which can be used to verify the NC codes.
