+Second line sets relative coordinate system (G91) and the retraction mode to R (98), let suppose that the current position is (X=100, Y=200, Z=300), so the cycle makes the below operations:
+1. rapid movement to the position (X=100, Y=200, Z=300+180) 
+2. rapid movement to the position (X=100+400, Y=200+500, Z=480)
+3. move down up to the position (X=500, Y=700, Z=480-60)
+4. rapid tool retraction at the position (X=500, Y=700, Z=480)
+5. repeat from point 2 with current position (X=500, Y=700, Z=480), the cycle is repeated for three times.
