数控加工仿真中的优化离散矢量模型

Optimized Discrete Vector Model of NC Machining Simulation

数控加工仿真是利用计算机模拟数控加工的过程。采用离散矢量法可以有较好的实时性和观察性。但在采用离散矢量法时,离散模型的建立对仿真的效果有很大的影响。而对于常用的采用均匀离散方式建立起来的仿真模型,对仿真精度与仿真速度的要求无法同时得到满足。本文采用了一种基于非均匀离散的优化模型可以有效地解决此点不足,并将详细论述这种仿真模型的建立、数据更新及其显示等内容。

The NC Simulation is used to simulate of the NC machining process. The Discrete Vector method can achieve the combination of both observability and real-time capacity. However, when using the even discrete method to construct the simulation model, there is a contradiction between the display precision and simulation speed. This essay will introduce and present an uneven discrete method-Optimized Discrete Vector Simulation Model. Using this model can resolve the above contradiction properly. This essay will discuss the construction, the data update and the display of this model in detail.
