  5. 5. Movement of Hammer• Generally the hammer of the rock drill moves 50~120 hertz, which means it finishes 50 to 120 cycles of movement in a second.• We set the cycle is 50, and the amplitude is 0.2 cm.
  6. 6. Key Features & Graph forMovement of Hammer•
  7. 7. Digging Depth• The Rock Drill digs the ground about 0.6cm in a second• However, as time goes, the depth of digging decrease because the ground become harder as it goes deeper
