Load inertia(JL)= Ball screw inertia(JB) + table inertia(JT)

JB = (p *p* L*D 4 ) / 32

JT = M *(P/(2*p *R))2 (In case that machine has counter weght JT =( M + Mc)*(P/(2*p *R))2)a) X axis

JB= 1.66x10-4(kg m 2)

JT= 1.37x10-4(kg m 2)

2)

b) Y axis JB= 1.51x10-4(kg m 2)

2)

c) Z axis JB=0.60x10-4(kg m2)

JT=0.76x10-4(kg m2)

3-2).Friction torque

Friction torque Horizontal(Tf)=(9.8*m*M*P)/(2p *R*h )

Friction torque Vertical (Tf)=(9.8*(M-Mc)*P)/(2p *R*h )

1) X axis

2) Y axis Tf =0.17(Nm)

3) Z axis Tf =0.52(Nm)

3-3).Cutting Thrust

The following formula can be used when max cutting torque is substituted for motor rated torque.

Max Cutting torque=Motor load torque at shaft + Friction torque = Motor rated torque

Motor load torque at shaft = P*103/(2*p *h *R) * Cutting Thrust *10-3

↓

Cutting Thrust(Ct) = (Motor Rated torque - Friction torque)*((2*p *h *R)/P)

1) X axis N

2) Y axis N

3) Z axis Ct=1058N
