Title (EN) MACHINE TOOL AND CONTROL DEVICE FOR MACHINE TOOL
(FR) MACHINE-OUTIL ET DISPOSITIF DE COMMANDE POUR MACHINE-OUTIL
(JA) 工作機械及びこの工作機械の制御装置
Abstract:
(EN)  The purpose of the present invention is to provide a machine tool with which entanglement of long, continuous shavings about a workpiece and/or a cutting tool is avoided, and damage to the machined surfaces of the workpiece is avoided, during a thread-cutting process being performed on the workpiece; and a control device for the machine tool. Provided are: a machining device (100) equipped with an oscillation setting means (C1) by which a workpiece (W) and a cutting tool (130) are advanced relative to one another in the machining direction while undergoing relative rotation, and are relatively oscillated in reciprocating fashion in a diametrical direction of the workpiece and subjected to a process of cutting spiral shapes multiple times in order to perform a thread-cutting process, the pattern of oscillation during each cutting process accompanied by reciprocating oscillation being set such that a section cut during a prescribed cutting process partially includes a section that has already been cut in a different cutting process; and a control device (C) for the same.
(FR)  La présente invention a pour but de fournir une machine-outil avec laquelle il est possible d'éviter l'enchevêtrement de longs copeaux continus autour d'une pièce à travailler et/ou d'un outil de coupe, ainsi qu'un endommagement aux surfaces usinées de la pièce à travailler, pendant un processus de coupe-taraudage qui est effectué sur la pièce à travailler; un dispositif de commande pour la machine-outil. Pour atteindre ce but, l'invention concerne : un dispositif d'usinage (100) pourvu d'un moyen d'établissement d'oscillation (C1) par lequel une pièce à travailler (W) et un outil de coupe (130) sont avancés l'un par rapport à l'autre dans la direction d'usinage, tout en subissant une rotation relative, et sont amenés à osciller de façon relative selon un mode en va-et-vient dans une direction diamétrale de la pièce à travailler, et sont soumis à un processus de coupe en spirales de multiples fois afin d'effectuer un processus de coupe-taraudage, le motif d'oscillation, pendant chaque processus de coupe, accompagné d'une oscillation en va-et-vient, étant établi de telle sorte qu'une section coupée pendant un processus de coupe prescrit comprend partiellement une section qui a déjà été coupée dans un processus de coupe différent; un dispositif de commande (C) pour celle-ci.
(JA) ワークに対してねじ切り加工した際に、長く繋がった切屑がワークや切削工具に巻き付くことを回避するとともにワークの加工面を傷つけることを回避する工作機械及びこの工作機械の制御装置を提供すること。 ワーク(W)と切削工具(130)とを相対回転させながら加工送り方向に沿って相対的に送り移動させ、ワークの径方向に相対的に往復振動させて複数回に亘って螺旋状に切り込み加工を行うことでねじ切り加工し、往復振動を伴う各切り込み加工時の振動のパターンを、所定の切り込み加工時の切削加工部分に、他の切り込み加工による切削済みの部分が部分的に含まれるように設定する振動設定手段(C1)を設けた工作機械(100)とその制御装置(C)。
