摘要： A numerical control apparatus (1) includes: a drive unit (10) controlling a main shaft rotating a workpiece, a first drive shaft feeding to move a cutting tool relatively to the workpiece along a perpendicular direction to a lead direction of a thread formed in a machining process, and a second drive shaft feeding to move the cutting tool relatively to the workpiece along the lead direction; and a vibration unit (482, 483) superimposing, on movement of the first drive shaft, vibration that is a reciprocating feed movement having a period having a predetermined ratio with a rotation period of the main shaft, and performs a thread cutting process for forming a thread on the workpiece by moving the cutting tool and the workpiece relative to each other and performing a cut process more than once on the workpiece. The numerical control apparatus includes a thread-cutting vibration adjustment unit (484) controlling the drive unit to shift phase of the vibration with respect to phase of the main shaft by a predetermined vibration phase shift amount every time in the cut process performed more than once.

摘要： When cutting a workpiece (5) with a cutting tool (6), a sinusoidal voltage (electrical energy) input in a piezoelectric element (9, 10) of an elliptical vibrator (2) transmitting elliptical vibration to the cutting tool (6) is efficiently converted to elliptical vibration (mechanical energy). A body part (7) of the elliptical vibrator (2) is cylindrically formed while a prescribed sinusoidal voltage is individually input in the piezoelectric element (9, 10) provided on the cylindrical body part (7) from a control mechanism (11) for generating elliptical vibration in the elliptical vibrator (2). Thus, the cutting tool (6) is elliptically vibrated for cutting the workpiece (5).

摘要： Die Erfindung betrifft ein Verfahren zur Erzeugung von Bruchspänen bei der Drehbearbeitung von Werkstücken mittels einer sich im Verlauf der Werkstückumdrehung verändernden Vorschubgeschwindigkeit des Drehwerkzeuges. Bei einer bekannten Verfahrensweise dieser Art konnte ein zuverlässiger Spanbruch micht erreicht werden und es war insbesondere nur möglich geradlinige Werkstückkonturen zu erzeugen. Mit der Erfindung soll ein zuverlässiger Spanbruch erreicht werden, auch bei der Bearbeitung von Werkstücken mit nicht geradlinigen Konturen. Dies wird dadurch erreicht, daß das werkzeug entlang der Linie der Vorschubvektoren periodisch schwingt, wobei die Schwingungsamplitude etwa dem halben effektiven Vorschubweg pro Umdrehung entspricht und die Wellenlänge der Amplitude so bemessen ist, daß sie selbst oder ihr ganzzahliges Vielfaches zuzüglich einer halben Wellenlänge stets gleich ist dem jeweiligen momentanen Werkstücksumfang durch den betrachteten Arbeitspunkt.

摘要： A tool holder assembly and method for intentionally inducing modulation in a machining process. The tool holder assembly is configured for mounting in a tool block on a machining apparatus and includes a tool holder body configured to be secured to the tool block of the machining apparatus, a tool holder mounted on the tool holder body and configured for securing a cutting tool thereto, and a device for imposing a superimposed modulation on the tool holder so as to move the cutting tool relative to the tool holder body and thereby relative to the tool. The tool holder assembly is useful in a process for producing chips having a desired shape and size, and particularly to a method of controllably producing nanocrystalline chips.
