A three-dimensional shape measurement system includes an image pickup unit, a storage device that stores image pickup conditions required in imaging for measurement as condition information for each of a plurality of combinations of the material and surface property of an object, and a measurement controller that controls driving of the image pickup unit. The measurement controller identifies the material and surface property of the object, specifies image pickup conditions corresponding to the identified material and surface property of the object based on the condition information, causes the image pickup unit to perform the imaging for measurement under the specified image pickup conditions, and measures the shape of the object based on the obtained image for measurement.

Three-dimensional shape measurement system and machine tool system

Provided is a cell controller for controlling an operation of a machining cell including two or more machines and one or more robots as work resources, the cell controller being configured to control the operation of the machining cell based on a production program recorded with one or more processes to be executed at the time of producing only one article of a corresponding item in the machining cell among production programs prepared corresponding to one or more items produced in the machining cell.

Cell controller

A control device which controls a servo motor of a machine tool in the event of power failure is provided. The control device includes a power failure detecting unit () which monitors an input power supply () and when power failure is detected, instructs servo motor amplifiers () to decelerate and stop servo motors () while maintaining a controlled state, and instructs a spindle motor () to suspend application of electricity, an alarm threshold changing unit () which, in response to a power failure detection signal from the power failure detecting unit (), changes alarm threshold values for direct current voltage reduction abnormality of a power circuit (), the servo motor amplifiers (), and a spindle motor amplifier () from values for a normal operation to values during power failure, and a retraction operation instructing unit () which, in response to the power failure detection signal from the power failure detecting unit (), instructs servo motor amplifiers () to perform a retraction operation by a small distance which is defined in advance.
