Actuated disc cutting (ADC) is one of the latest developments in rock cutting. While there have been significant developments in understanding its mechanics, the ADC induced rock fragmentation remains poorly understood. In efforts to improve the current understanding, this paper evaluates the cutting fragments and the relationship between fragments and force dynamics. Rock cutting tests were performed on two types of sedimentary rocks using a CSIRO customized ADC unit, known as Wobble. Wobble is equipped with force, torque, and displacement transducers to monitor the cutting process. This paper studied the dynamics of force signals, and as a result of these analyses, the concept of chipping to the crushing ratio ( $R_{cc}$) was introduced. The force drop distribution was also evaluated together with the specific energy ($SE$). The rock fragments generated were examined through two sets of the laser-scanning machine. Characterization of rock fragments explored the particle size distribution, fractal dimension ($D_s$), and coarseness index ($CI$) based on the fragment minimum width. Evaluation of the distribution profile indicated both force drops and fragment sizes follow a type of distribution known as Generalized Extreme Value (GEV) distribution. GEV is often associated with brittle failure of a structure. Correlation analyses further emphasised the previous observations that ADC key variables—the geometry factor $\epsilon$, the actuation factor $2\pi \upsilon$, and the penetration rate $p$, are the major controlling factors of $R_{cc}$, $SE$, $D_s$, and $CI$.

驱动盘切割 (ADC) 是岩石切割的最新发展之一。虽然在理解其力学方面取得了重大进展，但对 ADC 引起的岩石破碎仍知之甚少。为了提高目前的认识，本文评估了切割碎片以及碎片与力动力学之间的关系。使用 CSIRO 定制的 ADC 装置（称为 Wobble）对两种类型的沉积岩进行岩石切割测试。Wobble 配备了力、扭矩和位移传感器来监控切割过程。本文研究了力信号的动力学，作为这些分析的结果，碎屑与破碎比的概念（${\mathrm{电阻}}_{CC}$) 的介绍。还评估了力降分布以及比能（$秒乙$）。产生的岩石碎片通过两组激光扫描机进行检查。岩石碎片的表征探讨了粒度分布、分形维数（$D_{秒}$) 和粗糙度指数 ($C\mathrm{一世}$) 基于片段最小宽度。分布曲线的评估表明，力下降和碎片大小都遵循一种称为广义极值 (GEV) 分布的分布类型。GEV 通常与结构的脆性破坏有关。相关性分析进一步强调了之前的观察结果，即 ADC 关键变量——几何因子$\epsilon$, 驱动因子 $2\pi ü$, 渗透率 $磷$, 是主要的控制因素 ${\mathrm{电阻}}_{CC}$, $秒乙$, $D_{秒}$， 和 $C\mathrm{一世}$.
