To provide a processing device that enables the economical use of dresser boards. [Solution] The processing apparatus includes a holding means for holding the dresser board 12, a cutting means that rotatably supports a rotating shaft on which a cutting blade 26 is mounted, an X-axis moving means for moving the holding means in the X-axis direction, a Y-axis moving means for moving the cutting means in the Y-axis direction, a Z-axis moving means for moving the cutting means in the Z-axis direction, and a control means. The control means calculates the width of the cut formed in the dresser board 12 from the outer diameter (d) of the cutting blade 26 and the amount of cut (t) into the dresser board 12 as ω = 2(dt-t 2 ) 1 / 2 The calculated (ω) is used as the basis to set the index amount (Xi) of the cutting blade 26 in the X-axis direction relative to the dresser board 12.

The application discloses a state-aware electrode cap self-adaptive dressing method and system, relates to the dressing processing technical field, acquires a process signal sequence in an electrode cap dressing process, and is segmented to obtain a plurality of discrimination windows; signals in each discrimination window are processed to obtain signals in each discrimination window after processing; a feature vector is constructed based on the signals in each discrimination window after processing; the feature vector is compared with each threshold value, a current dressing state is discriminated in combination with a state discrimination rule; and based on the current dressing state, a corresponding parameter update rule is combined to automatically update control parameters of equipment. The control parameters are automatically adjusted according to the discriminated dressing state, so that the end face quality stability is improved and the probability of adhesion is reduced without increasing complex hardware.

This invention relates to a dressing method for a multi-threaded grinding worm (1) for gear grinding, the grinding worm (1) comprising multiple worm threads (2, 3), each worm thread being dressed by a dressing tool (4) having at least one dressing stroke (H1, H2, H3) to provide the desired profile for the grinding worm (1). To improve the method and obtain more reliable information on whether the dressing of the grinding worm is adequate by improving monitoring of the dressing, the method of the present invention includes: a) dressing the first worm thread (2), measuring and recording at least one process parameter (P1) during the dressing; b) dressing another worm thread (3), measuring and recording the process parameter (P1) during the dressing; c) after dressing all worm threads: combining the recorded process parameter (P1) data; d) comparing the combined data of the process parameters (P1) with the data stored in the machine controller, and checking whether the combined data is within a predetermined acceptable range; e) if the combined data is not within the predetermined acceptable range, outputting a signal.

This invention relates to the field of precision grinding and polishing technology, specifically to a dressing device and method for damping cloth polishing pads. The dressing device includes a lifting arm mounted on a grinding and polishing machine. At the end of the lifting arm is a rotary dressing component integrating suction, blowing, rinsing, and scraping functions. The dressing component is connected to an air pump and a liquid storage device via a valve assembly. It also includes a detection device for real-time monitoring of the polishing pad surface morphology. The detection device, lifting drive, rotary drive, and valve assembly are all electrically connected and centrally controlled by a control system. The dressing method, based on the dressing device, obtains the surface cleanliness of the polishing pad through real-time detection and automatically starts and stops rotation and corresponding dressing function combinations according to different cleanliness levels, achieving closed-loop intelligent dressing. This application realizes online, real-time sensing and on-demand, precise, and integrated dressing of the surface state of the damping cloth polishing pad, significantly improving the degree of automation, process stability, and polishing pad lifespan.

The application discloses a micro-groove network structure ball head dressing device and method based on magnetic field enhanced force rheology, wherein the dressing device comprises a polishing tank containing polishing liquid, a jig is arranged in the polishing tank, a workpiece is fixed in the polishing tank by the jig and is immersed in the polishing liquid, and the dressing device further comprises a magnetic ball head connected with a driving device through a rod. The dressing method is applied to the dressing device and comprises the following steps: fixing the workpiece; setting a ball center of the ball head on a rotary center line of the workpiece, adjusting an oblique plane of the rod relative to a tangent plane of a concave surface of the workpiece, and forming the same gap between the ball head and the workpiece at different positions of the concave surface; preparing the polishing liquid and pouring the polishing liquid into the polishing tank until the workpiece to be processed is immersed; and driving the ball head to feed and process by the driving device, so that the polishing medium in the polishing gap generates local thickening and solidification and other rheological effects, under the action of flow pressure effect, "particle cluster" containing abrasive grains micro-cut the surface of the workpiece, the surface material of the workpiece is removed, and then the dressing is realized.
