A numerical controller is provided with an axis motion control unit configured to control the motions of a table axis and a press axis according to a machining program. The axis motion control unit starts the motion of the press axis for a first block at a first top dead center, if the state of the table axis satisfies a condition adapted for the start of the motion of the press axis for the second block and if the motion of the press axis for the first block is not completed, and the axis motion control unit starts the motion of the press axis for a second block at a second top dead center lower than the first top dead center, thereby overlapping the motions of the press axis for the first and second blocks.

The present disclosure relates to a method for determining the bending angle on a bending machine, wherein the bending machine includes an upper tool and a lower tool for reshaping a workpiece by bending along a bending line. One or more measuring arrangements are positioned on the bending machine, which together include at least one illumination device and in each case at least one image acquisition device. Each measuring arrangement is assigned a different surface portion of the workpiece which lies laterally adjacent to the bending line and extends along the bending line. A light pattern is imaged on the workpiece by means of the at least one illumination device of a respective measuring arrangement onto the assigned surface portion. The light pattern contains a plurality of zones which are arranged side by side along the bending line.

A bending machine with a work area image capture apparatus has a machine frame, a longitudinally extended, fixed machine table, and a longitudinally extended press beam moved by a drive relative to the frame and guided therein. The longitudinal expanse and the press beam movement direction define a working plane establishing a front working and manipulation space and a rear machine space. An image capture apparatus above the machine table in the machine space has a capture region oriented toward the machine space and is connected with a display configured to represent the captured image of the capture region. The capture apparatus is connected with the display by an image processing processor having a coordinate transformation module configured the captured image perspective. The coordinate transformation module is connected with a wireless position determination system configured to determine the machine operator position in the working and manipulation space.

A bending process is controlled for bending a bending body, such as a bending profile. A bending device has a bending unit provided with at least one bending element that executes a defined movement based on a control signal.

A bending method includes acquiring a reference value of an original position of a punch with respect to a die for each processed part before an operation of bending of a workpiece by a bending machine including the punch and the die is started, storing each of the acquired reference values in association with each of the processed parts, reading the reference value associated with the processed part to which the bending is to be executed, acquiring a measurement value of the original position after the operation of the bending of the workpiece is started, calculating, based on the acquired measurement value, a secular change amount from the reference value or a previous measurement value as a secular change correction value for a pushing amount of the punch with respect to the die or the original position of the punch, and resetting, for each predetermined trigger condition, the pushing amount or the original position by using the secular change correction value during an automatic operation of the bending of the workpiece.

A method for operating a press, wherein a relationship between a detected component property (current value) of the final product (e.g. surface quality), the provided material property of the semi-finished product (e.g. sheet thickness), and the detected production parameter (e.g. pressing pressure) is determined, for example, by a self-learning algorithm, on the basis of precedingly determined differential values between target and current values of the component property. The algorithm is subsequently used for targeted selection of samples for quality monitoring.
