To provide a machining condition setting support system for enabling more appropriate machining conditions to be determined by enabling stability limit diagrams to be represented more highly accurately.SOLUTION: A machining condition setting support system 1 comprises: a stability limit diagram generation unit 13 capable of generating stability limit diagrams SD1 to SD4, corresponding respectively to cutting depth sections Aa1 to Aa4 which are a plurality of sections into which a cutting depth that can be determined to be included in machining conditions is divided, the stability limit diagrams SD1 to SD4 each defining a relation between a rotation speed of a tool T or a workpiece W, and a maximum cutting depth at which chatter does not occur; and a chatter occurrence determination unit 14 configured to determine, by using stability limit diagrams SD1 to SD4 corresponding to an evaluation object cutting depth as the machining conditions, out of the plurality of stability limit diagrams SD1 to SD4 that may be generated, whether the chatter occurs in the case with the evaluation object cutting depth and an evaluation object rotation speed included in the machining conditions.SELECTED DRAWING: Figure 3 【課題】安定限界線図をより高精度に表すことができるようにすることで、より適切な加工条件を決定できるようにするための加工条件設定支援システムを提供する。【解決手段】加工条件設定支援システム１は、加工条件として取り得る切込量が複数の区間に分割されており、分割されたそれぞれの切込量区間Ａａ１～Ａａ４に対応する安定限界線図ＳＤ１～ＳＤ４であって、工具Ｔまたは工作物Ｗの回転速度とびびりが発生しない最大切込量との関係を定義したそれぞれの安定限界線図ＳＤ１～ＳＤ４を生成可能に安定限界線図生成部１３と、生成され得る複数の安定限界線図ＳＤ１～ＳＤ４のうち、加工条件としての評価対象切込量に対応する対象の安定限界線図ＳＤ１～ＳＤ４を用いて、評価対象切込量、および、加工条件に含まれる評価対象回転速度の場合に、びびりが発生するか否かを判定するように構成されたびびり発生判定部１４とを備える。【選択図】図３
