TOOL INSTALLATION STATE ESTIMATION SYSTEM AND MACHINE TOOL

To early detect deterioration of an installation state of a tool to a main spindle.SOLUTION: A tool installation state estimation system 1 comprises: a measurement tool 140 comprising a body part 143 having a tapered outer surface 141 which is common to a tool 150, and a vibration source 144 which is installed on the body part 143 and generates vibration; a sensor 2 which is provided on a main spindle 112 which pulls the tapered outer surface 141 of the measurement tool 140 into a tapered inner surface 112a and brings both into close contact with each other, and detects the vibration which is generated at the vibration source 144 and is propagated to the main spindle 112 side via the tapered outer surface 141 and the tapered inner surface 112a; and an estimation part which estimates an installation state of the tool 150 on the basis of the vibration detected by the sensor 2.SELECTED DRAWING: Figure 1 【課題】主軸への工具の装着状態の悪化を早期に検出する。【解決手段】工具１５０と共通のテーパ外面１４１を有する本体部１４３と、本体部１４３に装着され振動を発生する振動源１４４とを備える測定用ツール１４０と、測定用ツール１４０のテーパ外面１４１をテーパ内面１１２ａ内に引き込んで密着させる主軸１１２に設けられ、振動源１４３において発生し、テーパ外面１４１およびテーパ内面１１２ａを経由して主軸１１２側に伝播してきた振動を検出するセンサ２と、センサ２により検出された振動に基づいて工具１５０の装着状態を推定する推定部とを備える工具装着状態推定システム１。【選択図】図１
