摘　　要：金刚石等超硬磨料砂轮抗磨损能力强,磨削性能优良,本文以ARM激光修整超硬磨料砂轮为研究对象,设计了其自动平衡控制系统,包括TTL电平输出硬件模块、主控硬件模块、信号采集处理硬件模块,并分析了激光CCD位移传感器的抗干扰处理和PCB设计方面的抗干扰处理,实现了上位机和下位机的一体化运行,满足了超硬磨料砂轮修整精度的要求。在处理器S3C2440上构建Linux操作系统软件环境,选用金刚石砂轮进行金刚石砂轮修整实验。结果表明,修整后砂轮圆跳度误差约为25.5μm,结合剂在砂轮表面去除非常明显,地形地貌和容屑空间良好,符合激光修整超硬磨料砂轮要求的精度。Laser trimming ARM super-hard abrasive grinding wheel based on the automatic balance control system is designed. The TTL level output hardware module,main control hardware module,signal processing module and the hardware are designed for its automatic balance control system. The analysis of anti-jamming processing of CCD laser displacement sensor and PCB design are carried out to realize the integrated operation of the upper and lower machines,which meets the super abrasive grinding wheel dressing precision. The software environment of Linux operating system is built on the processor S3C2440,and the diamond grinding wheel dressing experiment is carried out. The results show that,the wheel round jump error is about 25.5 m after dressing,the binder removal is very obvious on the surface of the grinding wheel,ultra-hard abrasive particles are uniformly distributed,and meets the super abrasive grinding wheel precision.
