WIPO Patent Application WO/2022/118709

A1

The present invention makes it easy to estimate the value of a prescribed parameter used in a dynamics simulation for creating or modifying a machining program executed by a machine tool, or for cutting process design. A cloud server 10 for estimating the value of a prescribed parameter used in a dynamics simulation for creating or modifying a machining program executed by a machine tool 20, or for cutting process design, includes a processor 14, wherein the prescribed parameter relates to a tool used by the machine tool 20 or to the equipment of the machine tool 20, and the processor 14 is configured to: (A) transmit trial cutting data for trial cutting of a prescribed test piece for estimating the prescribed parameter; (B) acquire shape data relating to the shape of the test piece after the test piece has been subjected to the trial cutting by the machine tool, on the basis of the trial cutting data; and (C) estimate the prescribed parameter on the basis of the acquired shape data.
