KEY FORMULAS
Confirm the tool geometry, coating, material grade, coolant and machine speed limit. Workpiece diameter is used for turning; tool diameter is used for milling and drilling.
Power is net cutting power estimated from the specific cutting force you enter; it does not include spindle efficiency.
- Use climb milling where the machine and setup permit.
- Confirm tool overhang and holder runout before increasing feed.
- Use suitable coolant or air delivery for chip evacuation.
- Reduce engagement when machining harder materials.
- Monitor wear and validate results on the actual setup.
- Metric milling example: D = 10 mm, Vc = 300 m/min, fz = 0.04 mm/tooth and Z = 4 give n ≈ 9,549 rpm and F ≈ 1,528 mm/min. With ap = 10 mm and ae = 10 mm, Q ≈ 152.8 cm³/min. These inputs illustrate the formula; they are not recommended cutting data.
- Metric turning example: workpiece D = 50 mm, Vc = 150 m/min and fn = 0.10 mm/rev give n ≈ 955 rpm and F ≈ 95.5 mm/min. With ap = 1 mm, Q = 15 cm³/min. Use the workpiece diameter for turning.
- Metric drilling example: tool D = 10 mm, Vc = 80 m/min and fn = 0.10 mm/rev give n ≈ 2,546 rpm and F ≈ 254.6 mm/min. Q ≈ 20 cm³/min. Drilling feed is per revolution, not per tooth.
