A numerical controller generates movement command data, and performs an interpolation process based on the generated movement command data to generate and output interpolation data. Further, in the case of a state in which a press operation in punch press machining is started from a different position from a position of a preset rising edge, an overlap time is calculated based on a position of a punch head when the press operation is started, and an output timing of interpolation data related to an axis controlling the press operation is controlled based on the calculated overlap time. In this way, even when there is a change in press stroke, a dead time may be prevented from being generated.

An information processing apparatus is capable of reducing a burden on an operator to process data exchanged between systems. An information processing apparatus processes data including a data structure defining a plurality of machining processes selected from a laser cutting process, a punch cutting process, and a non-cutting process and implemented on a plate workpiece. The data structure includes shape information defining positions of machining lines that serve as targets of the machining processes, and machining information defining a type of each machining process corresponding to each machining line among the machining processes.

A method of forming an ice resistant surface includes determining, based at least in part on a desired pattern of frost formation, a vertex angle for a ridge that is to be formed on a substrate. The method also includes determining, based at least in part on the desired pattern of frost formation, a vertex height for the ridge that is to be formed on the substrate. The method further includes forming a plurality of ridges on the substrate, where each ridge in the plurality of ridges has the vertex angle and the vertex height.

Highly accurate press working is performed while responding to mechanical alteration due to thermal expansion. Prior to a series of processing to a workpiece, a servomotor control unit moves a slide to a stop position, and a sensing value detecting unit detects a sensing value of a sensing element at the stop position of the slide, and stores the detected sensing value. Then, in the series of processing, the sensing value detecting unit detects a sensing value of the sensing element at the stop position of the slide, and stores the detected sensing value in the processing sensing value storing unit. A correction value calculating unit calculates a correction value based on the two store values, and a servomotor control unit controls the servomotor based on the detected slide position, the slide position that has been set, and the correction value calculated by the correction value calculating unit.

An accumulated wear amount calculation section calculates a wear amount of a blade edge of a punch and a wear amount of a blade edge of a die when a tool set of the punch and the die has processed a sheet metal once. The accumulated wear amount calculation section calculates an accumulated wear amount of the blade edge of the punch and an accumulated wear amount of the blade edge of the die by accumulating wear amounts of respective times when the tool set has processed the sheet metal multiple times. A tool management information managing section manages a state of the blade edge of each punch and each die by causing a tool management information storage section to store tool management information associating a tool identification code given to each punch and each die with the accumulated wear amounts calculated by the accumulated wear amount calculation section.

A method for forming a stamped component from a blank material with an industrial stamping machine during a stamping process includes measuring a plurality of parameters of the stamping process. The parameters are provided as variables of the stamping process. The method further includes analyzing, by a stamping process model, the plurality of parameters to adjust the stamping process for the blank material, defining, by the stamping process model, a control parameter of the industrial stamping machine for the blank material, and stamping the blank material with the industrial stamping machine based on the defined control parameter to form the stamped component.

The invention notably relates to a method for determining specifications of the input of a manufacturing operation that outputs a part having cut-outs. The method comprises providing specifications of the output part, including a user-designed B-Rep having cycles of edges and modeling the part, the cut-outs being represented by the user with tunnels in the B-Rep, determining the set that consists of all cycles being the one having the smallest length in a respective equivalence class, performing a process on the set that includes iterating replacing a cycle when this reduces the length, and deleting a cycle when a sum results in a boundary cycle, otherwise replacing the cycle by the sum when this reduces the length.

The invention offers an improved solution to detect, in a B-Rep having cycles of edges and modeling a part having cut-outs represented by tunnels, location of at least part of the tunnels.

A display device for punching and/or pressing machines. The display device can be constructed to be modular and of compact size so as to be positioned as desired on new and existing machine designs. The display device is formed with displays, which are configurable to provide a plurality of qualitative and quantitative information. The display device can be configured to be function with consoles of punching and pressing machines so as to be one or more of a supplemental device, an interfacing device, and an interactive device.

There is provided a control system for an apparatus for taking out a molded product, the apparatus performing appropriate operation when a collision occurs while a servo system control section is manually operated. When a collision detection section outputs an operation stop command, a deviation clearing section performs clearing operation to bring deviations in a servo system control section to zero with the servo system control section kept on. Positioning is completed as the deviations are brought to zero, which enables operation to be performed again. When a retracting operation is performed after the operation is stopped, servomotors are operated according to an operation command, which allows smooth retraction from the collision state.

A monitor for maintaining a mold cycle count with an actuator sending a count signal to a processor following a mold operation. The monitor further includes a timer having an active mode and a sleep mode. The processor generates an average cycle time and an activity percentage of the mold taking into account active and sleep periods of the mold.
