The conditions under which reamers are used and the results which are desired vary so widely that it is impossible to set up any guide to cover each possible combination. A few of the variables which affect reamer cutting action are:
1. | Speed |
2. | Feed |
3. | Use of guide bushings |
4. | Material |
5. | Condition of machine |
6. | Rigidity of set-up |
7. | Rake of cutting edges |
8. | Reliefs on reamer |
9. | Amount of stock to be removed |
10. | Finish required |
11. | Tolerance of hole |
