◆ Cutting conditions of End Mills
● Types of end mill
| Conventional milling | Climb milling |
|
|
|
 |
Cutting speed Tooling point diameter Revolution per minute π :3.14 |
● Method of solving revolution by cutting speed |
|
 |
|
● Method of solving feed of worktable by feed of each tooth |
|
Vf = fz*Z*n (mm/min) |
Feed of worktable (mm/min)
Feed of each tooth (mm/t) Tooth number of end mill |
● Cutting depth |
Revolution per minute. Revolution per minute. |
There is a limit cutting depth according to the required cutting allowance, capability of machine tool, and edge length of end mills. |
|
● Conventional milling and climb milling |
|
Using carbide end mill, making the lifetime of tooling long and getting good surface roughness, recommend climb milling. |
|
When there is sand inclusion in the surface of processed materials and when thermal
cutting surface is rough and uneven, Conventional milling is recommend. |
