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

<p>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.</p> <p>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.</p> <p>The uploaded files show the results of these cutting experiments.</p>
