鑽孔功率與扭矩計算器
Estimate ideal drilling metal removal rate, net cutting power, input power and spindle torque using a specific cutting energy approximation.
結果是根據上述輸入參數計算得出的；範例數值僅供說明之用，並非針對特定工具的速度／進給建議。.
公式與計算方法
Q = π D² RPM fn / 4000 cm³/min; Pc = Q × kc / 60000 (kW); Pinput = Pc / η; T = 9550 Pc / RPM (N·m).
This simplified engineering estimate starts from the drilling material removal rate and assumes an effective specific cutting force entered by the user. Power and torque are then derived from volumetric cutting work. Tool geometry and actual cutting data can change the apparent specific cutting force substantially; manufacturer drilling-power calculations may use different coefficients and torque models.
重要假設與限制
Approximation only, especially for multi-margin drills, indexable drills, pilot holes and changing engagement. Not suitable as a certified motor-sizing or safety assessment. Enter an appropriate effective kc or independently verified specific cutting energy.
常見問題
Is the kc value universal?
No. It depends on workpiece material, tool geometry, uncut chip thickness and other factors.
Does estimated input power equal the motor nameplate rating?
No. Nameplate selection requires allowances for overload, transient torque and other machine loads.
