A method for machining at least one workpiece surface to apply a texture pattern to at least one section of the workpiece surface using a laser, based on image data specifying an image of the texture pattern applied to the at least one section of the workpiece surface and model data specifying a three-dimensional geometry of a surface form corresponding to the at least one section of the workpiece surface. Control data and segment data are generated based on the image and model data. The control data specify one or more segment sequences for each track line. Each segment sequence has track segments where the laser guides the texture pattern application to the at least one section of the workpiece surface; wherein the track segments of a segment sequence include one or more laser track segments where the laser travels in the switched-on state at a constant machining setpoint speed.

A contour accuracy measuring system and a contour accuracy measuring method are provided. The contour accuracy measuring system captures location coordinate data of shafts of a machine tool. The location coordinate data are calculated to obtain a first true round trajectory on an inclined plane as reference information. The contour accuracy measuring system then adjusts parameters of the locations of the shafts based on the location coordinate data of the shafts of the reference information to generate a second true round trajectory on the inclined plane, so as to get to know whether the locations of the shafts after the parameters are adjusted comply with a standard. Therefore, the overall measurement process can be speeded up by automatically measuring the parameters and automatically testing an operating status.

The present application discloses a motion control method for dual-spindle machining and a dual-spindle machine apparatus. A control device performs data reconstruction of segmentation and checkpoint setting according to first and second data, respectively, to correspondingly form first and second instruction sequences, thereby simultaneously controlling two motion control cards, allowing two machining devices coupled at a back end of the motion control cards to perform machining on two opposite sides of a workpiece. With the checkpoints arranged in the instruction sequences, the machining devices each having one machining tool are provided with a collaboration mechanism, so that the control device is allowed to continue sending instructions of the next segment to the two motion control cards upon arrival of both the instruction sequences at the checkpoints. Thus, the simultaneous dual-spindle apparatus not only achieves the feature of high efficiency of single-side separate machining but also provides the feature of dual-side collaboration, solving the issue of damage caused by mutual interference during a synchronous dual-spindle operation.

A linear motor system includes: a stator including first to tenth coils; a mover including a permanent magnet; a switcher that switches one or more power supply target coils; and first to tenth amplifiers provided in one-to-one correspondence with first to tenth coils. One or more amplifiers that serve as new one or more power supply target amplifiers immediately after the switching calculate Δθ (t0), which is a position deviation at time t=t0, based on Δθ (t0)=Δθ (t0−td)+A−B, where A is a difference between an instructed position at time t=t0 and an instructed position at time t=t0−td, and B is a difference between an actual position at time t=t0 and an actual position at time t=t0−td, and supply power to the power supply target coils by the position deviation Aθ (t0).

A control device for controlling a machine tool, wherein the machine tool and the control device are configured such that a tool and/or workpiece disposed on the machine tool can be moved with at least one first speed and at least one second speed. When switching from a movement with the first speed to a movement with the second speed, the tool or the workpiece is at first stopped prior to the execution of the movement with the second speed, if the second speed is greater than the first speed by at least a predetermined factor. The control device has an input device for triggering the movement with the second speed, and the subsequent execution of the movement with the second speed is triggered by an operator input on the input device. A corresponding control method for controlling a machine tool is also described.
