Abstract
(EN)
A cutting machine (1) that comprises a machine body (100) and an NC device (200). The NC device (200) has a tool diameter correction amount computation part (201), a processing path computation part (202), and a drive control part (203). The tool diameter correction amount computation part (201): recognizes a non-circular tool path (TP) that is included in processing conditions (CP) and corresponds to a cutting tool that cuts a workpiece (W); determines whether a plurality of processing plane formation locations (MPL or MPR) are on the tool path (TP); and, upon determining that the plurality of processing plane formation locations (MPL or MPR) are on the tool path (TP), selects an arbitrary processing plane formation location (MPL or MPR). The processing plane formation locations (MPL or MPR) are locations on the tool path (TP) at which a tool diameter is greatest. The processing path computation part (202) generates a tool diameter correction control signal (TS). The drive control part (203) controls the machine body (100).

L'invention concerne une machine de coupe (1) qui comprend un corps de machine (100) et un dispositif NC. Le dispositif NC (200) a une unité de calcul de quantité de correction de diamètre d'outil (201), une unité de calcul de trajectoire de traitement (202) et une unité de commande d'entraînement (203). L'unité de calcul de quantité de correction de diamètre d'outil (201) : reconnaît une trajectoire d'outil non circulaire (TP) qui est incluse dans des conditions de traitement (CP) et correspond à un outil de coupe qui coupe une pièce (W); détermine si une pluralité d'emplacements de formation de plan de traitement (MPL ou MPR) se trouvent sur la trajectoire d'outil (TP); et, lors de la détermination que la pluralité d'emplacements de formation de plan de traitement (MPL ou MPR) se trouve sur la trajectoire d'outil (TP), sélectionne un emplacement de formation de plan de traitement arbitraire (MPL ou MPR). Les emplacements de formation de plan de traitement (MPL ou MPR) sont des emplacements sur la trajectoire d'outil (TP) au niveau desquels un diamètre d'outil est le plus grand. L'unité de calcul de trajectoire de traitement (202) génère un signal de commande de correction de diamètre d'outil (TS). L'unité de commande d'entraînement (203) commande le corps de machine (100).

切削加工機(1)は加工機本体(100)とNC装置(200)とを備える。NC装置(200)は工具径補正量演算部(201)と加工軌跡演算部(202)と駆動制御部(203)とを有する。工具径補正量演算部(201)は加工条件(CP)に含まれる工具軌跡(TP)を認識し、工具軌跡(TP)に複数の加工面形成位置(MPLまたはMPR)が存在するか否かを判定し、複数の加工面形成位置(MPLまたはMPR)が存在すると判定された場合に任意の加工面形成位置(MPLまたはMPR)を選択する。工具軌跡(TP)は加工対象物(W)を切削加工する切削工具に相当し、かつ、非円形状を有する。加工面形成位置(MPLまたはMPR)は工具軌跡(TP)において工具径が最大となる位置である。加工軌跡演算部(202)は工具径補正制御信号(TS)を生成する。駆動制御部(203)は加工機本体(100)を制御する。
