Abstract

See full text

A spindle control system for a milling machine is provided. The milling machine includes a column, an overarm, a spindle for mounting a cutter, a first motor mounted on the column for driving movement of the overarm, and a second motor mounted on the overarm for driving rotation of the spindle. The spindle control system includes a distance sensor and a temperature sensor, each to be mounted on the overarm and to be disposed proximate to the end portion of the spindle. The spindle control system further includes a central control unit for determining a compensation parameter based on the displacement sensed by the distance sensor and the temperature sensed by the temperature sensor, and for controlling movement of the overarm by the first motor through a compensation distance based on the compensation parameter to compensate for at least one of the cutter deformation and the spindle deformation.
