Abstract
A numerical control system of a machine tool includes an analysis device. The analysis device includes acquisition portions which acquire chronological speed control data when the work is machined and which acquire spatial machined surface measurement data after the machining of the work, a data-associating processing portion which associates the speed control data and the machined surface measurement data with each other, a machined surface failure detection portion which detects failures on the machined surface of the work, an identification portion which identifies the speed control data of failure locations corresponding to the machined surface measurement data of the failure locations, a failure interval detection portion which detects the interval of the failures and a calculation portion which calculates the frequency of vibrations based on a machining speed based on the speed control data of the failure locations and the interval of the failures.
