Estimating the term…
To include an analysis processing unit that obtains a movement command for moving on a movement path in a machining program, and vibration conditions for vibrating along the movement path, a command-movement-amount calculation unit that calculates a command-movement amount per unit time, a vibrational-movement-amount calculation unit that uses the vibration conditions to calculate a vibrational-movement amount per unit time at a time corresponding to the movement command, and a movement-amount combining unit that combines the command-movement amount with the vibrational-movement amount to calculate a combined movement amount, and that acquires a movement amount within the unit time such that a position, which has moved from a reference position for calculating the combined movement amount by the combined movement amount, is located on the movement path.
A numerical control device by which machining is performed on a machining object while moving a tool and the machining object relative to each other by two or more drive shafts provided in at least one of the tool and the machining object, the numerical control device comprising:
A numerical control device comprising:
