摘要： A method for calibrating a CNC machine including providing instructions for machining a surface of a distortion-free object, selecting a true axis of movement of a toolhead of the machine using the instructions, instructing the toolhead to travel on an object to be machined along the true axis of movement, but where the toolhead actually travels along an actual axis that is deviated from the true axis as a result of the surface distortions on the object to be machined, selecting multiple points along the actual axis traveled by the toolhead on the object to be machined, comparing the distance of the multiple points along the actual axis from the true axis to determine offset amounts from the true axis corresponding to a lack of straightness of the object to be machined, and modifying the instructions to compensate for the offset amounts before uploading the instructions to a CNC controller.

摘要： A method includes positioning a linear cutting edge inclined at an angle greater than 0° and smaller than 90° with respect to a Z axis at a cutting start position displaced from a position on an X axis along a direction of a Y axis in a three-dimensional orthogonal coordinate system in which an axial line of rotation of a rotation symmetry plane is defined as the Z axis, an axis in a radial direction of the rotation symmetry plane is defined as the X axis, and an axis orthogonal to both of the Z axis and the X axis is defined as the Y axis and machining the rotation symmetry plane by feeding the cutting edge from the cutting start position along a track having an X axis component, a Y axis component, and a Z axis component while the cutting edge is in contact with a rotating machine component.

摘要： A machine tool has a carriage, has a workpiece carriage for carrying a workpiece from which material is removed by a tool carried by a tool carriage. A two-axis scale is attached to one of the carriages, and cooperates with a reading head attached to the other carriage. The output from the reading head is processed by signaling processing means to provide an indication of the position and/or movement of the carriages relative to each other and for generating positional data about one or both of the carriages to assist in controlling their movement in order to perform a machine operation. By directly measuring the relative positions of the two carriages, problems arising from, for example, distortions of the machine frame on which the carriages are mounted are at least mitigated. A preferred embodiment of the machine incorporates a second reading head attached to one carriage and incorporating the scale on another carriage so that the outputs from the two reading heads can be used to determine whether there has been any relative angular displacement of the paths followed by the carriages. There is also provided a method of determining the linear movement of one of the carriages relative to the other, and the machining process achieved using the machine tool.

摘要： A robot for mounting a chip on a printed circuit board includes a body movable along a forward/backward axis, and a chip-carrying head unit movable longitudinally along the body transversely of the forward/backward axis. Due to manufacturing tolerances the longitudinal axis of the body is slightly inclined relative to a leftward/rightward axis oriented perpendicular to the forward/backward axis by an error angle which can be measured. The head unit is intended to be positioned at target coordinates on the forward/backward axis and the leftward/rightward axis, respectively. An operation unit determines, as a function of the error angle, a position of the head unit relative to the body, and a position of the body relative to the forward/backward axis, which would place the head unit at the target coordinates. A controller connected to the operation unit actuates a drive mechanism for moving the head unit and body to those respective positions.
