To suppress chatter vibration during cutting work.SOLUTION: A working condition determination support device comprises: an input reception part that receives input of tool information including information concerning specification of a tool attached to a machine tool, and work-piece information including information concerning material quality of a work-piece which is cut by the tool attached to the machine tool; a storage part that stores machine tool information including information concerning vibration characteristic of the machine tool; and a recommendation working condition determination part that determines recommendation working condition within a range excluding a working condition range in which forced chatter vibration specified by use of the machine tool information occurs, and within a range of a tool proper rotational speed which has been predetermined for each combination of the tool information and the work-piece information, and outputs information representing the recommendation working condition to an output part.SELECTED DRAWING: Figure 5 【課題】切削加工時のびびり振動を抑制する。【解決手段】加工条件決定支援装置は、工作機械に装着される工具の諸元の情報を含む工具情報と、工作機械に装着された工具により切削加工を施される工作物の材質の情報を含む工作物情報との入力を受け付ける入力受付部と、工作機械の振動特性の情報を含む工作機械情報を記憶している記憶部と、切削加工の切削抵抗の変化に起因する自励びびり振動が生じない加工条件の範囲から、工作機械情報を用いて特定される強制びびり振動が生じる加工条件の範囲を除外した範囲内、かつ、工具情報と工作物情報との組み合わせごとに予め定められている工具の適正回転速度の範囲内で推奨加工条件を決定して、推奨加工条件を表す情報を出力部に出力する推奨加工条件決定部と、を備える。【選択図】図５
