FANUC is a group of companies, principally FANUC Corporation of Japan, Fanuc America Corporation of Rochester Hills, Michigan, USA, and FANUC Europe Corporation S.A. of Luxembourg, that provide automation products and services such as robotics and computer numerical control systems. FANUC is one of the largest makers of industrial robots in the world. FANUC had its beginnings as part of Fujitsu developing early numerical control and servo systems. The company name is an acronym for Factory automation numerical control.In 1972, the Computing Control Division became independent and FANUC Ltd was established.FANUC is listed on the first section of Tokyo Stock Exchange and is a constituent of the TOPIX 100 and Nikkei 225 stock market indices. It is headquartered in Yamanashi Prefecture.The company's clients include US and Japanese automobile and electronics manufacturers. Use of industrial robots has allowed companies like Panasonic in Amagasaki to run factories which produce 2 million television sets a month with just 25 people.FANUC has joint ventures, subsidiaries, and sales offices on 5 continents and over 22 countries. It is the largest maker of CNC controls by market share with 65% of the global market. and is the leading global manufacturer of factory automation systems. Wikipedia.

A management system of injection molding machines includes molding cells, each of which including at least an injection molding machine and a temporary storage device configured to store data from devices in each molding cell at prescribed intervals, and a management device that is connected with the molding cells through communications lines and stores the data stored in the temporary storage device. The temporary storage device overwrites the data sequentially from the oldest data to the newest data in cycles, and stores the data for a prescribed number of cycles. A signal that is selected in advance from signals generated by the devices in each molding cell or by the management device is input to the temporary storage device as a trigger signal, and when the temporary storage device receives the trigger signal, the temporary storage device outputs the stored data to the management device.


An optical fiber connection unit able to efficiently remove heat generated in the optical fiber connection unit. The optical fiber connection unit includes a closed circulation path, through which coolant for eliminating heat generated in the optical fiber connection unit by a laser beam propagating through the optical fiber connection unit circulates, and a coolant circulation device for causing the coolant to flow and circulate in the circulation path.


An apparatus for generating a control program for sequence control. The sequence-control programming apparatus includes a storage section configured to store plural types of given ladders respectively describing plural types of commands separately from each other by ladder logic, the commands related to a specific operation to be executed by the operating system; a selection input section configured to receive a selection input for selecting a plurality of desired given ladders from the plural types of given ladders; and a program generating section configured to extract the plurality of desired given ladders from the storage section in accordance with the selection input, and combine the extracted desired given ladders to convert the extracted desired given ladders into a single system-compatible ladder configured to make the operating system execute the specific operation, so as to generate the control program.


A selection device which can reduce labor involved in the setting operation of a controller. The selection device includes an information reception part which receives a machine condition, a storage which stores specification data, a selection part which compares the machine condition received by the information reception part with the specification data stored in the storage to select the electric motor system that meets the machine condition, and a parameter generation part which generates a controller parameter configured to allow a controller which controls the electric motor system selected by the selection part to set in the controller, an operation parameter involved in operating the electric motor system.

A low-cost laser power sensor having sufficient measurement accuracy with respect to received light intensity of the power sensor. The power sensor has a sensor substrate which receives monitor light, and a filter which attenuates the intensity of the laser beam before being received by the sensor substrate. The filter is constituted from a material having a laser transmissivity equal to zero, and has a plurality of openings within an irradiation range where the monitor light is irradiated. A summation of opening areas of the openings is equal to or more than 50% of the irradiation range. A part of the laser beam, which is irradiated to the filter and passes through the openings, is directly received by the sensor substrate.

A wire electric discharge machine according to invention prevents occurrence of failure beforehand and prevents machining stop. This can be effected by acquiring an image of a part using an image information collection unit such as a visual sensor with respect to matters, which requires inspection management of the amount of a wire accumulated in a wire electrode storage box, a remaining amount of a wire of a wire bobbin, a level of a machining liquid of a water reservoir and the like, and issuing warning when it is determined, based on the obtained image information, that the failure is highly likely to occur as the wire deposition amount is close to a limit of the wire electrode storage box, the wire remaining amount is small, or the machining liquid level falls below a set value to deal with the state based on this warning.


A wire electrical discharge machine is configured to perform removal machining of a workpiece by applying a voltage to a machining gap between a wire electrode and the workpiece through a feeder to generate electrical discharge and is provided with a feeder deterioration detection unit configured to detect deterioration of the feeder. The feeder deterioration detection unit includes a detection unit configured to detect a machining current value during the machining and a detection unit configured to detect the number of electrical discharges during the machining.
