摘　　要：环模是饲料加工机器的核心部件,其钻削加工是制约生产效率和产品质量的瓶颈工序。以钻头工况噪声为测试和研究对象,通过噪声功率谱分析得到钻头的实时磨损状态;融合计算机技术、嵌入式系统技术和短距离无线通信技术,研制了一种环模数控钻床钻头噪声监测系统,并开发了相应的人机交互软件,实现了钻头工作状态的实时检测和自动处理。实验测试表明,钻头噪声功率谱特征变化明显,钻头工况监测系统运行稳定可靠,目前产品已经投入实际生产测试。Annular mould is a primary part of the feed pellet mill machine,and drilling is a key processing for the CNC manufacturing of annular mould.The operating mode noise of drill bits is tested in this paper,in order to distinguish the wear condition of drill bits by the noise analysis on power spectrum.By using the computer,embedded system and short distance wireless communication technologies,a novel drilling noise monitoring system and corresponding and a humancomputer interaction software are achieved for the CNC drilling machine,to distinguish and dispose the worn-out drill bits automatically.The test result shows that the power spectrum characteristic of drill bit noise is distinct,as well as the monitoring system for wear condition of drill bits is reliable,and it has been applied and test in actual productions.
