This article discusses a comparative analysis of the wear and quality of planer knife blades used in wood planers. The novelty in this work is the use of a simple coordinate measuring machine with a vision system to assess the wear of the cutting edges of planer knives. The primary objective of the research described in this paper was to verify whether the wear of the cutting edge of planer knives can be measured quickly and accurately using an optical coordinate measuring machine with a vision system. To date, contact profilometry methods have been used for this purpose, which require a specialist apparatus and qualified measuring equipment operators and are expensive and time-consuming. The research presented in this work was conducted on twelve planer knives. The condition and wear of the working surfaces of the tested knives were assessed using an optical digital microscope. The wear of the cutting edge of the knives was measured using two methods: the contact profilometry method and an optical coordinate measuring machine equipped with a vision system. The edge profiles and their parameters obtained by the optical method were compared to the results of measurements with a stylus profilometer. Based on the research and analyses conducted, it was found that the optical method used in this research significantly shortens the time of measuring the wear of the cutting edges of planer knives. In addition, this method has a wider measurement range, and the obtained measurement results are characterized by lower measurement uncertainty.
本文讨论了木工刨床所用刨刀刀片磨损情况及质量的对比分析。这项工作的新颖之处在于使用了一台带有视觉系统的简易坐标测量机来评估刨刀刀刃的磨损情况。本文所述研究的主要目的是验证是否可以使用带有视觉系统的光学坐标测量机快速、准确地测量刨刀刀刃的磨损情况。迄今为止，一直使用接触轮廓测量法来进行此操作，这种方法需要专门的仪器以及合格的测量设备操作人员，而且成本高昂且耗时。本研究对十二把刨刀进行了测试。使用光学数码显微镜评估被测刀具工作表面的状况和磨损情况。刀具刀刃的磨损采用两种方法进行测量：接触轮廓测量法和配备视觉系统的光学坐标测量机。将通过光学方法获得的刀刃轮廓及其参数与触针轮廓仪的测量结果进行了比较。基于所进行的研究和分析发现，本研究中使用的光学方法显著缩短了测量刨刀刀刃磨损的时间。此外，该方法具有更宽的测量范围，并且所获得的测量结果具有更低的测量不确定度。
