End Mill Cutting Conditions
Calculate end mill spindle speed, feed rate, and machining time. When you select the workpiece material and tool, standard guidelines from the "Cutting Conditions Table" below will be entered automatically. As you change values, the results update right away. The values you enter are used only within this browser and are not sent anywhere.

| 回転数 n | min⁻¹ | |
|---|---|---|
| 送り速度 Vf | mm/min | |
| 加工時間 |
計算式
- 回転数 n ＝ 1000 × Vc ÷（π × D）
- 送り速度 Vf ＝ fz × z × n
- 加工時間 ＝ L ÷ Vf（L を入れたときだけ）
切削速度と1刃送りは、被削材と工具を選ぶと、このページの「切削条件表」の目安（範囲なら真ん中）が入ります。値は目安です。工具のカタログと機械の条件で確かめてください。
Cutting Condition Guidelines
Cutting speed is in m/min, and feed per tooth is in mm/tooth. Feed per tooth is a guideline for tool diameters around φ10; make it smaller for smaller diameters. For values given as ranges, the middle value is used.
| Workpiece Material | Tool | Cutting Speed | Feed per Tooth | Notes |
|---|---|---|---|---|
| Structural steel (SS400) | Carbide end mill | 80–120 | 0.03–0.06 | |
| Structural steel (SS400) | HSS end mill | 20–30 | 0.02–0.04 | |
| Carbon steel (S45C) | Carbide end mill | 70–100 | 0.03–0.05 | |
| Carbon steel (S45C) | HSS end mill | 18–25 | 0.02–0.03 | |
| Stainless steel (SUS304) | Carbide end mill | 50–80 | 0.02–0.04 | Work-hardens easily, so do not stop the feed |
| Stainless steel (SUS304) | HSS end mill | 10–15 | 0.01–0.03 | |
| Cast iron (FC250) | Carbide end mill | 80–120 | 0.03–0.06 | |
| Cast iron (FC250) | HSS end mill | 15–25 | 0.02–0.04 | |
| Aluminum (A5052) | Carbide end mill | 200–400 | 0.05–0.10 | |
| Aluminum (A5052) | HSS end mill | 60–100 | 0.04–0.08 |
