CONTACT DYNAMIC STIFFNESS CALCULATION SYSTEM, MACHINING ESTIMATION DEVICE, AND PROCCESSING SYSTEM

WIPO Patent Application WO/2024/075284

A1

This contact dynamic stiffness calculation system (130) calculates contact dynamic stiffness data (Ci, Ki) between a workpiece (W) and a tool (T) exhibited via contact between the workpiece (W) and the tool (T) when machining in a machining device (2) for machining the workpiece (W) using the tool (T). The contact dynamic stiffness calculation system (130) has a correspondence relationship storage unit (103) that stores a correspondence relationship between the contact dynamic stiffness data and a machining condition index that changes according to the condition of the machining of the workpiece (W) by the tool (T), a machining condition index acquisition unit (124) that acquires the machining condition index, and a contact dynamic stiffness calculation unit (121) that calculates the contact dynamic stiffness data on the basis of the acquired machining condition index and the correspondence relationship. Moreover, in the correspondence relationship, the degree of change of the contact dynamic stiffness data relative to the machining condition index varies.
