The mechanical shearing machine of the mechanical shearing machine manufacturer has gone through a period of rapid growth. Affected by various international and domestic factors, the market environment of the mechanical shearing machine industry of mechanical shearing machine manufacturers has undergone significant changes: the total demand has dropped significantly, and the demand structure has accelerated upgrading. As an old market for shears, the market for shears of mechanical shears manufacturers is shrinking, but the level and level of demand for shears is rapidly increasing. The mechanical shearing machine companies of the mechanical shearing machine manufacturers provide equipment for the automobile, aircraft, ship, aerospace, power generation and other industries. To meet the industrial upgrading needs of these industries, the mechanical shearing machine product research and development level of the mechanical shearing machine manufacturer must constantly improving.
On the mechanical shearing machine of the mechanical shearing machine manufacturer, due to the reverse dead zone of the drive components (such as servo motor, servo hydraulic motor and stepping motor, etc.) on the feed transmission chain of each coordinate axis, the reverse of each mechanical motion transmission pair The existence of errors such as backlash causes each coordinate axis to form a reverse deviation when it changes from a forward motion to a reverse motion, which is usually also called backlash or loss of momentum. For the mechanical shearing machine of the mechanical shearing machine manufacturer that adopts the semi-closed-loop servo system, the existence of reverse deviation will affect the positioning accuracy and repeat positioning accuracy of the machine tool, thereby affecting the processing accuracy of the product. The reverse deviation of the mechanical shearing machine of the mechanical shearing machine manufacturer will also increase with the gradual increase of the movement pair gap due to wear. Therefore, it is necessary to periodically check the reverse deviation of each coordinate axis of the mechanical shearing machine of the mechanical shearing machine manufacturer. Perform measurement and compensation.
There are usually several addresses in the memory of mechanical shearing machine manufacturers to store the backlash value of each axis. When a certain axis of the machine tool is commanded to change the direction of movement, the numerical control device will automatically read the backlash value of the axis, compensate and correct the coordinate displacement command value, so that the mechanical shearing machine of the mechanical shearing machine manufacturer can accurately Position at the commanded position to eliminate or reduce the adverse effect of the reverse deviation on the accuracy of the machine tool. Generally, the numerical control system has only a single backlash compensation value available. In order to take into account the high and low speed motion accuracy, in addition to doing better mechanically, the reverse deviation value measured during fast motion can only be used as Compensation value input, so it is difficult to achieve balance, taking into account the rapid positioning accuracy and interpolation accuracy during cutting.
