To study the multiple parameters of the wood peeling process, a micro-lathe peeling machine was developed to correlate high-speed camera observations of the cutting zone with the measured cutting forces. Such an experiment requires a high level of synchronization between the camera and the force measurements, not only in terms of acquisition timing but also regarding the bandwidth of the force measurement system. However, the embedded dynamometer in the experimental micro-lathe was found to have a limited bandwidth, exhibiting internal resonances starting as low as 500 Hz. This study first aims to characterize the vibratory behavior of the dynamometer and the overall structural response to dynamic loading. Secondly, it seeks to extend the usable frequency range (band-width) of the force measurements using dynamic compensation methods, to match the acquisition frequency of the cutting forces with that of the video camera. This step is a prerequisite for addressing further challenges, such as performing inverse identification of process parameters.

摘要

To study the multiple parameters of the wood peeling process, a micro-lathe peeling machine was developed to correlate high-speed camera observations of the cutting zone with the measured cutting forces. Such an experiment requires a high level of synchronization between the camera and the force measurements, not only in terms of acquisition timing but also regarding the bandwidth of the force measurement system. However, the embedded dynamometer in the experimental micro-lathe was found to have a limited bandwidth, exhibiting internal resonances starting as low as 500 Hz. This study first aims to characterize the vibratory behavior of the dynamometer and the overall structural response to dynamic loading. Secondly, it seeks to extend the usable frequency range (band-width) of the force measurements using dynamic compensation methods, to match the acquisition frequency of the cutting forces with that of the video camera. This step is a prerequisite for addressing further challenges, such as performing inverse identification of process parameters.
