A thermal displacement compensation apparatus includes a temperature measuring unit, a thermal displacement estimating unit, a thermal displacement compensation unit, a displacement measuring unit, a data recording unit, a thermal displacement compensation learning unit, and a displacement measurement timing diagnostic unit. The displacement measuring unit measures a displacement of a machine tool after compensating an axis command value. The thermal displacement compensation learning unit determines a thermal displacement estimation formula based on temperature information and the displacement recorded in the data recording unit. The displacement measurement timing diagnostic unit compares the temperature information at a past displacement measurement recorded in the data recording unit with current temperature information obtained from the temperature measuring unit, and determines whether to measure the displacement by the displacement measuring unit or not at a predetermined diagnosis timing.

A spindle motor rotates a spindle to which a cutting tool is attached. A feed mechanism moves the cutting tool relative to a thin workpiece. A machining apparatus repeatedly performs a first process of causing the feed mechanism to feed the cutting tool relative to the thin workpiece in a height direction of a rising wall to perform a plunge process on the thin workpiece, and a second process of causing the feed mechanism to feed the cutting tool relative to the thin workpiece in a width direction or the height direction of the rising wall to perform a finishing process on the thin workpiece.

An apparatus for active contact force control is disclosed. The apparatus can have upper flange on which to mount a production tool. The apparatus can be mounted, via a lower flange, on a multi-axis machine to obtain spatial motion together with the corresponding production tool. The apparatus can comprise a housing inside which can be a linear actuator connected to guides. Mechanical connection between a ball screw and the upper flange can contain a force sensor and at least one spherical joint. The connection between the spherical joint and the upper flange can be formed using a mechanical dissipative element made of elastic dissipative elements and a disc plate positioned between the elastic dissipative elements.
