To provide a control panel for machine tools that improves operability and enables even an unskilled person to easily grasp a procedure for moving a screen to a target screen. A plurality of screen data are classified into a plurality of groups and classified into main screen data and sub-screen data associated with the main screen data in each of the groups. A control section displays the main screen data and displays the sub-screen data on a display section according to a type of an input to a plurality of main screen corresponding buttons.

Control panel for machine tools and management system for machine tools

A numerical control unit is provided that can change an override value according to various workpiece materials and can extend the tool life. A numerical control unit includes a variation storage unit that stores a variation in override value of a feed speed or a spindle speed for each workpiece material, an override value setting unit that sets the override value based on the variation in override value according to the material of a workpiece being machined; and a control unit that changes the feed speed or the spindle speed based on the override value.

There is provided a flexible manufacturing system that can reliably place a workpiece that isn't defective piece in a state where the workpiece will be machined again. After a pallet is conveyed to a standby position and before machining of the workpiece attached to the pallet is started, controllers determines whether machining of the workpiece with a corresponding machining device is possible. When it is determined that machining is possible, the controller starts machining with the machining device. When it is determined that machining is impossible, the controller make a conveyor convey the pallet from the standby position to a pallet storage room, and stores the machining status information on the conveyed pallet as the machining-waiting state.

Flexible manufacturing system

An NC program creating device is provided that can automatically insert in an NC program a code that can be executed simultaneously with feeding in a non-cutting state. If it is determined by a determination unit that there is a standard code M03, M06, M10 before or after a non-cutting feed code G00 or G30 in an NC program, a new code placement unit places, instead of the standard code M03, M06, M10, a simultaneous execution code M103, M805, M110 corresponding to the standard code M03, M06, M10 before the non-cutting feed code G00 or G30, and places after the non-cutting feed code G00 or G30 a code that performs at least a prescribed operation of the standard code M03, M06, M10 other than an operation of the simultaneous execution code M103, M805, M110.

A flexible manufacturing system that makes it possible to give a higher priority to machining of a workpiece that is a super-urgent item is provided. When a pallet to which a workpiece, which is a super-urgent item, is attached is loaded on a loading station, a second controller gives a command to a conveyor to convey a pallet to which a workpiece, which is a normal item, is attached and which is located at a standby position of a pallet changer to a pallet storage room. Then, the second controller controls the conveyor to convey the pallet to which the workpiece, which is the super-urgent item, is attached and which is loaded on the loading station to the standby position.
