Stability of Milling Process with Variable Spindle Speed

10.02.2021The spindle speed (nominal spindle speed for VSS milling) is 7,000 rpm: (a) = 1 mm, (b) = 0.5 mm, (c) = 0.1 mm, (d) = 1 mm, (e) = 0.5 mm, and (f) = 0.2 mm. RVA = RVF = 0.3 for (d), (e), and (f). To compare the computational efficiency, we refer to Figure 5, which shows the time consumption using RKCDM and SDM.

Stability of Up

The VSS milling dynamics is described by a set of delay differential equations with time varying periodic coefficients and a time delay. A semi-discretization scheme is used to discretize the system over one period, and the infinite-dimensional transition matrix is reduced to a finite-dimensional matrix over this period.

Motors and variable speed drives

Speed control allows motors to be oversized to meet extreme requirements without wasting energy during low demand. Pumps and fans typically have variable torque loads subject to the 'cube law', meaning that reducing motor speed by 20% can reduce power required by 50%. Constant torque loads occur where torque is independent of speed.

Variable speed wind turbine

A variable speed wind turbine is one which is specifically designed to operate over a wide range of rotor speeds. It is in direct contrast to fixed speed wind turbine where the rotor speed is approximately constant. The reason to vary the rotor speed is to capture the maximum aerodynamic power in the wind, as the wind speed varies.
