The numerically controlled spiral camber envelope milling method includes: inputting basic parameter from the industrial computer to the data base; contour design and calculation comprising extracting or inputting basic parameter data, establishing screw bolt profile mold and fairing treatment in curve interpolation course and storing the datan into data base; automatically programming the numerically controlled machining course; and performing numerically controlled machining via transmitting the machining program to the motion controlling unit and machining with the driving module. The integrated control system includes control panel, CNC controller, measuring unit, feeding servo unit, servo motor, frequency varying driver, mainshaft motor and electric loop unit.

Description

technical field [0001] The invention belongs to the control technology of a numerically controlled machine tool, in particular to a numerically controlled envelope milling method for a helical curved surface and an integrated control system thereof. Background technique [0002] With the development of the machinery manufacturing industry, complex and precise parts have been widely used in various important industrial fields of the national economy, but the generation of the spiral surface is complicated, the processing process is difficult, and the precision requirements are high, requiring multi-axis linkage CNC machine tools Envelope processing is formed. Since the machining accuracy, production efficiency and surface quality of the workpiece depend to a large extent on the performance and programming accuracy of the control system of the machine tool, this requires the numerical control system of the CNC machine tool to have stronger computing and programming capabilitie...
