Processing device

The invention relates to a machining device. A machining device (1, 201) for machining a workpiece (W) supported by a workpiece support member (20, 30, 40, 60, 220, 230, 240) by means of a tool (T, T2) is provided with a processing unit (3, 203) for processing the workpiece (W) supported by the workpiece support member (20, 30, 40, 60, 220, 230, 240) using contact dynamic rigidity data (Cwc, Kwc) between the workpiece (W) and the workpiece support member (20, 30, 40, 60, 220, 230, 240) exhibited by contact between the workpiece (W) and the workpiece support member (20, 30, 40, 60, 220, 230, 240). The state of the workpiece (W) or the tool (T, T2), the shape of the workpiece (W), the shape of the tool (T, T2), and/or the mechanical state of the machining device (1, 201) during machining are estimated. 本发明涉及一种加工装置。在通过工具(T、T2)加工被工件支承部件(20、30、40、60、220、230、240)支承的工件(W)的加工装置(1、201)中，具备处理部(3、203)，其使用由工件(W)与工件支承部件(20、30、40、60、220、230、240)的接触而展现的工件(W)与工件支承部件(20、30、40、60、220、230、240)之间的接触动态刚性数据(Cwc、Kwc)，来进行加工的控制或者推断加工
