Micro-grinding with microscale machine tools is a micro-machining process in precision manufacturing of microscale parts such as micro sensors, micro actuators, micro fluidic devices, and micro machine parts. Mechanical micro-machining generally consists of various material removal processes. Micro-grinding of these processes is typically the final process step and it provides a competitive edge over other fabrication processes. The quality of the parts produced by this process is affected by process conditions, micro-grinding wheel properties, and microstructure of materials. Although a micro-grinding process resembles a traditional grinding process, this process is distinctive due to the size effect in micro-machining because the mechanical and thermal interactions between a single grit and a workpiece are related to the phenomena observed in micro-machining. However, there have not been enough modeling studies of the micro-grinding process and as a result, little knowledge base on t

微粉磨与微型机床是一种微型机械加工过程中的精密制造微型部件,如微型传感器,微致动器,微流体装置,微型机械零件。机械微加工一般包括各种材料去除过程。微粉磨这些进程通常是最后的流程步骤和它提供了一个竞争优势其他制造工艺。的质量,部分这一过程所产生的影响的工艺条件,微型砂轮性能和微观结构的材料。虽然微粉磨工艺类似于一个传统的磨削过程,这个过程是独特的,由于尺寸效应在微机械加工,因为和散热之间的相互作用单一砂砾和工件相关的现象,在微加工。然而,有没有足够的模拟研究微粉磨工艺,因此,了解甚少,这方面的基础上积累了。
在这项研究中,新的预测模型的微粉磨工艺是由巩固机械和热效应的单一砂砾相互作用模型微尺度材料去除。尺寸效应的微加工还包括在拟议的模式。为了评估热效应,热分割比率为实验校准并与哈恩的预测模型。然后,在此基础上预测模型,比较和分析实验数据进行了预测,鉴于整体microgrinding部队在X和Y方向。虽然有偏差的预测微型磨削力低的深度削减,这些差异是降低了切削深度增加。另一方面,优化的微型机床完成的基础上提出的设计战略。单独的数学模型的关键参数,如体积错误,机器的工作空间,和静,散热和动态刚度和补充进行了分析与实验用锤冲击试验。这些计算收益率的最佳大小的微型数控机床的技术资料的其它参数。
