摘要： 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.

摘要： A freeform surface included collimation lens is provided, which is designed through a freeform surface design process to provide an integrally-formed unitary structure. The design method includes a step of identifying an optic field pattern of light source, a step of performing graphic analysis of freeform surface tangential vector formula, a step of acquiring freeform surface control point, a step of constructing a three-dimensional model, and a step of performing geometric processing. Through these steps, tangential vectors of control points of each freeform surface are determined and an approximating process or an exact solution process is adopted to determine the coordinates of the points of the freeform surface. Three-dimensional modeling software is then employing to construct an ellipsoid collimation lens, which realizes an optic collimation performance of at least 88% when tested with a circular disk set at a distance of 200 meters and having a diameter of 35 meters.
