| Difference Between Up Milling and Down Milling
| | Up Milling | Down Milling |
| 1. | There is propensity to lift workpiece so extra clamping forces are required to fix job on table. | Forces are enough on job to press down. Thus clamping difficulty is not so much. |
| 2. | Cutter turns against direction in which the work is being fed. | Cutter turns in similar direction as to in which the work is being fed. |
| 3. | It use of cutting fluid is complicated. | It use of cutting fluid is simple. |
| 4. | Cutting force vary as of zero to maximum. | Cutting forces vary as of maximum to zero. |
| 5. | Job tool movement is in opposite way. | Job tool movement is in the similar direction. |
| 6. | Chip thickness differs as of minimum to maximum. | Chip thickness varies as of maximum to minimum. |
| 7. | It surface finish is improved. | It surface finish is improved, if it is free as of backlash error. |
| 8. | It is feasible. | It is unfeasible. |
