摘要： A numerical control device (1) includes a phase-difference calculation unit (481) that, when machining with vibrations is performed on a movement path, calculates a phase difference that is a difference between a vibrational forward-moving position that is a movement path relative to time generated based on a command block and a vibrational backward-moving position obtained by subtracting a vibration amplitude from the vibrational forward-moving position, from a vibration amplitude-to-feed ratio that is a ratio between amplitude of the vibrations and a feed speed of a tool to a workpiece, a movement-path generation unit (482) generating the vibrational forward-moving position and the vibrational backward-moving position as the movement path for each drive shaft by using the phase difference, a vibration-waveform generation unit (483) generating a reference vibration waveform to be superimposed on the movement path for each drive shaft by using vibration conditions, a vibrational-movement-amount generation unit (484) calculating a vibrational-movement amount on the movement path for each drive shaft by using the reference vibration waveform, and a movement-amount combining unit (485) generating a combined movement amount for each drive shaft by adding the vibrational-movement amount to the movement path.

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.
