Loyalty Tip: Any carpenter engraving machine, when machining the workpiece, such as machining path setting, machining program preparation, machining tool selection, machine tool problem, clamping problem and workpiece data, etc.
Any carpenter engraving machine, when machining the workpiece, such as machining path setting, machining program preparation, machining tool selection, machine tool problem, clamping problem and workpiece data, etc., the machining accuracy and machining power of the workpiece will be inevitable. As a result, the carpenter engraving machine is a high-precision and efficient processing equipment. The methods used to reduce the processing errors of the workpiece are mainly to reduce the original negligence method, the fault compensation method, the faulty transportation method, the negligence grouping method, the negligence uniform method and the faulty synthesis method.
First, the fault synthesis method to eliminate the fault of the machine tool itself is the most important way to ensure the accuracy of the workpiece. The fault synthesis method requires measurement of the original fault of each axis of the machine tool. The laser interferometer is the primary testing instrument for carpenter engraving machines because of its high measurement accuracy and active use.
Second, the fault compensation method The fault compensation method is to artificially create a fault, to offset the original fault of the process system, perhaps using a primitive over loss to offset another original fault, and then arrive at the carpenter engraving machine workpiece processing accuracy intention . Usually by reducing the machine tool vacancies, the rigidity of the machine tool is traveled, and the pre-loading is selected to make the relevant cooperation pre-tightening force and eliminate the vacancy effect. It is also possible to travel the workpiece and the stiffness of the tool to reduce the overhang of the tool and the workpiece to travel the stiffness of the process system. It is also possible to select a reasonable clamping method and processing method, reduce the cutting force and its modification, reasonably select the tool data, increase the rake angle and the main declination, and perform reasonable heat treatment on the workpiece data to improve the data processing function. Several ways.
Third, direct reduction of the original negligence method Direct reduction of the original negligence method refers to the direct elimination or reduction of the original original negligence factors that affect the processing accuracy. For example, after a long time of use, the carpenter engraving machine is inaccurately positioned and reversed because of the natural wear and tear.
4. Negligence and uniformity The method of negligence uniformity is to compare and correct each other with closely related appearances, perhaps using mutual benchmarking to arrive at the carpenter's engraving machine to eliminate the negligence of processing.
V. Faulty handling method The essence of the negligent handling method is the negligence caused by the assembly process system's assembly fault, force deformation and thermal deformation. If the carpenter engraving machine performs some hole machining, the coaxiality of the workpiece is not guaranteed by the spindle spindle rotation precision, but is ensured by the clamp. When the machine tool spindle and the workpiece are selected for the floating connection, the original fault of the machine tool spindle is not It affects the machining accuracy and is transported to the fixture to ensure machining accuracy.
Sixth, the fault grouping method in the carpenter engraving machine processing, because of the existence of process blank negligence, constitutes the processing fault of this process. There are two main reasons for the impact of rough negligence on this process: reaction negligence and positioning fault.
If the above-mentioned fault is too large, the machining accuracy cannot be guaranteed, and it is not practical to advance the accuracy of the blank or the machining accuracy of the previous process. At this time, the method of negligence grouping can be used, that is, the blank or the upper process standard is subdivided into n groups according to the fault, and the fault of each group is reduced to 1/n of the original, and then the relative orientation of the tool and the workpiece is adjusted according to each group or Adjusting the positioning components can greatly reduce the standard slack size of the entire batch of workpieces. The essence of the fault grouping method is to compensate for the lack of machining accuracy by means of the accuracy of the traveling measurement, and then arrive to eliminate the influence of processing fault.
