Cutting force data at different cutting depth to cut spacing ratios using a conical pick

This data was obtained by cutting 2 rocks samples at different cutting parameters using a conical pick. Namely UG2 reef and white sandstone samples. The cuts were made using a linear cutting machine.
In the tests the cutting depth, the cut spacing and the skew angle were changed. The tests were performed at cutting depths of 2 mm and 4 mm. The cut spacing was changed so that the cut spacing to cutting depth ratio was 1,2,3,4,5 and 6. The skew angle was changed from −10◦, 0◦ and 10◦. The attack angle was kept constant at 50◦. The cutting speed was the same for all the tests at 50 mm/s and sampling rate of 300 Hz was used for all the tests, for the strain gauge measurements. A cutting sequence consisted out of firstly pre-cutting the surface to simulate a rock face and then nineteen cuts. The first cut was an initial cut then three of each ratio was cut starting at a ratio one to six. After each cut the cut material was collected and weighed. The weighed mass and the density of the material were used to determine the specific energy.
The uploaded files show the results of these cutting experiments.

本数据集通过采用锥形钎具在不同切割参数下切割两块岩石样本获得，具体包括UG2珊瑚礁和白色砂岩样本。切割操作采用线性切割机进行。在实验中，调整了切割深度、切割间距和偏斜角度。切割深度分别为2毫米和4毫米，切割间距以切割深度比1:2、1:3、1:4、1:5和1:6进行变化。偏斜角度在-10°、0°和10°之间调整。攻击角度保持恒定，为50°。所有测试的切割速度均为50毫米/秒，采样频率为300赫兹，用于应变计测量。切割序列首先对表面进行预切割以模拟岩石表面，随后进行十九次切割。首次切割为初始切割，然后从比例1:6开始，对每个比例进行三次切割。每次切割后，收集切割材料并称重。通过称重质量和材料密度来确定比能。上传的文件展示了这些切割实验的结果。
