摘要
磨削技术已广泛应用于最后加工有光滑表面和高精度要求的零件。在过去的 30年里 ,经过广泛的研究 ,对磨削加工的许多方面有了一个较为清楚的了解。本论文的目的在于说明怎样利用我们对磨削过程的理解来预报磨削特性和获得最佳加工条件。一个集成了描述磨削过程中不同方面的分析模块的软件包已被开发出来。这软件包括三个主要模块 :仿真、校准和优化。仿真模块作为一个虚拟磨床来预测磨削过程和零件质量。校准模块通过实测参数如功率、表面粗糙度和椭圆度等对模型的系数进行修正 ,从而对实际磨削特性进行学习。优化模块是以最小化周期时间或以基于服从工件质量约束校正模型后的周期时间为目标来确定磨削和修整参数。本软件已被集成进了PC开放体系控制器 (OAC) ,作为智能磨削系统 (IGS)的基础。
Grinding is widely used for final machining of components requiring smooth surfaces and precise tolerances. Extensive research during the past 30 years has provided a relatively clear understanding of the many diverse aspects of the grinding process. The objective of this paper is to show how our understanding of the grinding process can be utilized to predict grinding behavior and achieve optimal operating conditions. A software package has been developed which integrates analytical models describing various aspects of the grinding process. The software contanis three main modules: simulation, calibration, and optimization. The simulation module serves as a virtual grinder to predict process behavior and part quality. The calibration learns from actual grinding behavior by modifying model coefficients based on measured parameters such as power, surface roughness, and out of roundness. Optimization is used to identify grinding and dressing parameters to minimize or target cycle time based on the calibrated models subject to workpiece quality constraints. The software has been incorporated into a PC Open Architecture Controller (OAC) as the basis for an lntelligent Grinding System (IGS).
