Abstract: A vibration-cutting condition setting device capable of facilitating a selection of a tool and a setting of parameters. The vibration-cutting condition setting device for a machine tool includes a display unit and a control unit. The control unit accepts a setting for controlling an object to be fed with an vibration. The setting includes a feed speed without the vibration (F) of the object, a first parameter (A) regarding a cycle of the vibration, and a second parameter (E) regarding an amplitude of the vibration. The control unit calculates a maximum feed speed (Fmax) of the object according to the feed speed without the vibration (F), the first parameter (A), and the second parameter (E) and then displays a value representing the calculated maximum feed speed (Fmax) on the display unit.

Abstract: A machine tool capable of facilitating the setting of the vibration cutting conditions. A control unit acquires a feed speed of a object to be fed without a vibration (Fa), a number of rotations of a spindle required for a single cycle of the vibration (K), and a returning amount (R) representing a distance of a returning feed per the single cycle of the vibration. According to the acquired parameters, the control unit decides at least one parameter among a cutting amount (D) representing a distance of a change in a position of the object per the single cycle of the vibration, a cutting feed speed (F) of the object, and a returning feed speed (B) of the object. The control unit controls the position of the object to be fed with the vibration at least according to the decided parameter.

Abstract: A drawer control apparatus capable of precisely discriminating whether the drawer open state is triggered by the drawer open command process or otherwise. The drawer control apparatus includes a command receiving unit, a drawer connection detecting unit, a command processing unit, a drawer open/closed signal receiving unit, and an open trigger discriminating unit. The command processing unit executes a drawer open command process upon receiving a drawer open command. The drawer open command process includes sending a drawer open signal and setting a process execution flag upon detecting presence of drawer connection. The drawer open command process ends upon detecting absence of drawer connection. The open trigger discriminating unit discriminates whether the drawer open state is triggered by the drawer open command process or otherwise according to a set state of the process execution flag upon receiving a signal representing the drawer open state.

Abstract: Provided is a machine tool capable of facilitating switching moving ranges of the moving unit. A moving-side cover provided on the moving unit covers part of a position of the driving apparatus in the moving direction. A supporting-side cover is provided in a position on a side of the first moving range of an end of the moving-side cover on a side of the second moving range in the moving direction to continuously cover the part of the position of the driving apparatus in the moving direction in cooperation with the moving-side cover in the first use state. The supporting-side cover forms a clearance in the moving direction with respect to the moving-side cover in the second use state. A slide cover is mounted on one of supporting-side cover and the moving-side cover slidably in the moving direction to close the clearance when slidably drawn out in the moving direction.
