A calibration area has a rectangular area and a peripheral area. The rectangular area includes a center area provided in the center portion and a first corner area, a second corner area, a third corner area, and a fourth corner area that are set at four corners sequentially in the circumferential direction. The center area has a line symmetry with respect to each of the two orthogonal axes passing through the center of the rectangular area. The heights of the areas are different.

A movable gantry system is described. In an example, the movable gantry system is configured to interface with jigs of different types or sizes and/or with different positions of a same jig and/or to perform operations on different parts mounted in such jigs. To do so, the movable gantry system includes an end effector, a gantry, and a computing system. The end effector is mounted within the gantry and provides at least rotational movement to perform operations on a part. The gantry is movable and interfaces with a jig holding the part. Further, the gantry provides translational movement to the end effector. The computing system identifies the gantry and the part and controls the gantry and the end effector, thereby facilitating the operations on the part.

A terminal device for assisting operation of a plurality of eyeglass manufacturing apparatuses which are used for performing different processes in manufacturing eyeglasses includes: a communicating device configured to communicate with the plurality of eyeglass manufacturing apparatuses; a processor; and memory storing computer readable instructions, when executed by the processor, causing the terminal device to execute: a setting instruction for setting, according to a process, a specific eyeglass manufacturing apparatus from the plurality of eyeglass manufacturing apparatuses as an eyeglass manufacturing apparatus of which the operation is assisted; and a controlling instruction for controlling the communicating device to send an operating signal input in the terminal device to the specific eyeglass manufacturing apparatus set by the setting instruction or controlling the communicating device to receive an input signal input in the specific eyeglass manufacturing apparatus set by the setting instruction.

Disclosed is a method of producing an assembly tool for assembling a first system comprising one or more components. The method comprises: for each component, determining, when the first system is attached to a second system, a position and orientation of that component relative to the second system and positions and orientations relative to the second system at which that component is to be supported; providing a frame; attaching, to the frame, a reference structure; providing a plurality of pickup devices each having a receiving element for receiving a component; and securing each pickup device to the frame such that a position and orientation relative to the reference structure of each receiving element is the same as a position and orientation at which a component is to be supported.

Provided is a processing apparatus where the exchange of an operating program for an apparatus body is not required each time a jig unit is exchanged. The processing apparatus includes an apparatus body and a jig unit. A master control device is mounted on the jig unit. Operations of the jig unit and the apparatus body are controlled by an operating program in the master control device.

The computing system stores, in a data store, information about an operation upon performed by the end effector after a datuming process based translational data and on rotational data.

A position calibration system and method are disclosed, in which a control unit is provided to control a positioner sensing module to scan a circular positioner provided on a positioning substrate in a first direction and a second direction so as to acquire midpoints of two scanned line segments and acquire an intersection of lines extending from the two center points in a direction perpendicular to the first and the second directions as a calibration reference point, which correspond to a centroid (a center) of the circular positioner. The calibration reference point functions as a reference point for positioning the positioning substrate with respect to the positioner sensing module and is stored in a memory unit. The calibration reference point can be used as a positioning point during installation of a machine and can also be used for calibration of a position of the machine.

Methods, systems, and apparatus, including computer programs encoded on computer storage media, for determining portions of an item that would be unsupported during three-dimensional printing. One of the methods includes obtaining data representing a three-dimensional model of an item to be created by a three-dimensional printer, processing data representing discrete portions of an upper layer of the three-dimensional model that are labelled as unsupported to place supports for at least some of the discrete portions that are labelled as unsupported, processing data representing any remaining discrete portions of the upper layer that are labelled as unsupported and for which a support for the remaining discrete portion would intersect with a lower portion in the three-dimensional model, generating, for each of the discrete portions labelled as a portion at which to generate a support, a support for the discrete portion in the three-dimensional model.
