Testing of High Speed Milling Spindle Ing. Josef Kekula Supervisor: Doc. Ing.Jaroslav Rybín,CsC Abstract: The paper deals with the experimental measurements of power of milling spindle prototype with air-turbine drive by compressed air. An …...In the case of CNC machining, the electrical network passes energy to the spindle 's electric motor, which passes it to the cutting tool. The cutting tool uses this energy to extract material from a workpiece. Assuming the efficiency is , the power required to remove the material is the same as the power used by the machine's motor.

Chip flow is a critical factor in milling cutter selection due to increases in spindle speeds, reduction in machine spindle power, and the increased use of machining centers as opposed to machines that perform milling exclusively. …...The spindle power was monitored and the time series trends were decomposed to study the frequency variation with different severities of tool wear conditions and processing parameters.
