为了解决抛物线轴类零件数控加工参数远程调试执行时间与显示时间差异较大、调试精度低的问题,设计了抛物线轴类零件数控加工参数远程调试系统。将抛物线轴类零件特征参数化,设定精度和时间约束条件,进行远程调试参数精度优化;通过加工轴类零件的一阶数学模型、二阶数学模型、一阶离散控制模型、二阶离散控制模型,建立了参数调试的时间优先级函数,计算优先级反转概率,获得多队列轴类零件参数调试时间最优解,完成抛物线轴类零件数控加工参数远程调试。实例验证结果表明,该系统的参数读取、传输速度及执行速度较快,执行与显示的时间差为9.02 ms,参数远程调试精度均在90%以上。

In order to solve the problem of remote debugging execution time between CNC machining parameters and poor debugging accuracy,the remote debugging system of CNC machining parameters is designed.Parameterize the features of parabolic shaft parts,set the accuracy and time constraints,and optimize the accuracy of remote debugging parameters;by processing the first-order mathematical model,second-order mathematical model,first-order discrete control model,and second-order discrete control model,establishes the time priority function of parameter debugging,calculates the priority reversal probability,obtains the optimal solution of parameter debugging time for multi-queue shaft parts,and completes the remote debugging of NC machining parameters for parabolic shaft parts.The example results show that when the number of parameter queues gradually increases,the system reads,transmits and performs faster,the time difference between execution and display is 9.02 ms,the interval is short,and the parameter remote debugging accuracy is above 90%.
