摘要： The table on which a workpiece is put can travel on a guide rail mechanism relative to a working head with a cutting tool mounted thereon. The table is connected through a nut to a ball screw part to move in an axial direction thereof as the ball screw part rotates. One end of the ball screw part is supported by a bearing and the other end is connected to a servomotor to be rotationally driven. A hollow part is provided in the table to receive therein a damper mechanism part, which comprises a spring, a damper, and a weight, the table and the weight being arranged to enable traveling separately on guide rails. Thereby, even when the workpiece is heavy, the weight can move relative to the table to effectively damp vibrations of the table in a feed direction.

摘要： A method for calculating depth of cut without any milling self-excited vibration. An initial value for machining-surface-perpendicular depth of cut is set. A cutting start angle and cutting end angle for a cutting edge is obtained, based on the initial value. A machining-surface-perpendicular depth of cut that causes no self-excited vibration is calculated. The maximum depth of cut that corresponds to the stability limit of a milling self-excited vibration is calculated, by repeating the calculation while modifying the initial value until the difference between the initial value and the calculation result becomes the same as, or smaller than, a given value. As a result, the stability-limit depth of cut is preliminarily analyzed to the milling self-excited vibration in consideration of a pick feed, the gradient angle of a workpiece, and a machining-surface curvature radius, so that man-hours required for creation and modification of NC data can be reduced.
