This control device for a machine tool has a display unit that displays an input screen via which machining information regarding machining to be performed on a workpiece is inputted and an input unit via which letters and/or numbers are inputted into machining-information fields on the input screen. When a machining-information field on the input screen is selected, the display unit displays a first input-assistance screen corresponding to said field. Input-support buttons are laid out on said first input-assistance screen. When an input-support button is pressed, a second input-assistance screen is displayed, and via an operation performed in accordance with said second input-assistance screen, the aforementioned field is filled in.

A machining center NC operation panel with a body temperature management function includes a visible range image camera and an infrared detection camera on a front surface of an operation panel. A storage unit has: an operator list; a face image file; and a body temperature management file for machine tool users and body-temperature managed users. A control unit includes: a face authentication processing unit; a work information processing unit that calls a work item assigned to the identified operator and displays it on a display unit of the operation panel so as to allow execution of a selection; and a body temperature acquisition processing unit that assesses whether or not the operator has a fever. When receiving a result of the assessment that the operator has a fever, the work information processing unit locks an operation screen of the display unit to inhibit continuation of an operation.

A method for squaring and edge-banding panels is described, with the steps of: loading a panel onto a member rotatable about a vertical rotation axis; rotating the rotatable member with predefined angular steps until it completes a complete revolution, sequentially stopping the panel in front of N processing work-stations, N>=2, arranged in a circular array around the rotatable member, wherein, during the rotation of the rotatable member, the panel is always held vertical; as the panel is stopped at the N work-stations, processing the panel edges using panel edge processing units installed at the N work-stations; and unloading the processed panel from the rotatable member.

The method enables high production rates in limited spaces.
