Checkfluid is an Ontario-based manufacturer of oil-sampling valves, which allow for consistent oil samples to be**taken from machinery that can be used for efficient maintenance scheduling. Recently, the company has observed**quality defects in certain products produced mainly by turning. In this project, U. Waterloo and Checkfluid will**collaborate to investigate the production line using advanced diagnostic tools, such that a solid picture of the**production process in terms of quality and efficiency bottlenecks can be drawn. The data to be collected includes,**tool imaging for tool life cycle analysis, measurement of CNC positioning errors using servo signals for the**determination of servo repeatability, laser interferometric measurements of the motion axes according to ISO**standards for the calculation of drive-axis volumetric errors, investigation of thermally generated errors, spindle**power monitoring for the correlation of power consumption with tool condition and quality outcomes, modal**testing for the characterization of the machine-tool vibration signature and the estimation of the static stiffness.**The data thus collected will be analyzed comparatively to come up with process improvement solutions, which will**be tested on the production floor with the help of Checkfluid staff. The findings from the measurements will be**also shared with other research teams working in parallel on process monitoring research. Apart from immediate**solutions related to their production line, Checkfluid will also utilize the knowledge gained from this project to**evaluate various options regarding future investment in process monitoring and automation technologies in the**Industry 4.0 framework.

Checkfluid 是一家位于安大略省的油样阀制造商，它可以从机器中采集一致的油样，从而用于高效的维护计划。近期，该公司发现某些主要通过车削生产的产品存在**质量缺陷。在这个项目中，U. Waterloo 和 Checkfluid 将合作使用先进的诊断工具来调查生产线，从而可以准确地了解**生产过程中的质量和效率瓶颈。要收集的数据包括**用于刀具生命周期分析的刀具成像、使用伺服信号测量 CNC 定位误差用于**确定伺服重复性、根据 ISO** 标准对运动轴进行激光干涉测量以进行计算驱动轴体积误差的研究、热产生误差的研究、主轴**功率监控以了解功耗与刀具状况和质量结果的相关性、模态**测试以表征机床振动特征以及估计静态刚度。**将分析由此收集的数据相对地提出流程改进解决方案，并将在 Checkfluid 员工的帮助下在生产车间进行测试。测量结果**还将与并行进行过程监控研究的其他研究团队共享。除了与其生产线相关的直接**解决方案外，Checkfluid 还将利用从该项目中获得的知识**评估有关**工业 4.0 框架中过程监控和自动化技术的未来投资的各种选项。
