Abstract

The invention belongs to the technical field of numerical control machining, and particularly relates to a single-machine automatic alignment calculation-point-free machining method. A self-made measuring head point collecting program is used, and a calculation formula is designed according to different machining requirements. Point position acquisition and automatic calculation of coordinate system offset angle point positions are realized. The technical problems that in the current production preparation process, errors are prone to occurring and efficiency is low due to the fact that offsetis calculated through manual point location alignment are solved. By using the method to process the blank benchmark, the time for manually straightening the product is reduced. At the same time, theadded cross curve intersection angle verification and theoretical point position calibration can effectively discover alignment errors or workpiece lineation errors. The program performs automatic reading without human intervention, so that the error rate is reduced, the time is saved, and the production efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of numerical control processing, and in particular relates to a single-machine automatic alignment and point-free processing method. Background technique [0002] For aviation casing products, many special-shaped parts need to calculate the coordinate and angle offset between the actual coordinate system and the theoretical coordinate system of the workpiece through the position of the hole system. The traditional method firstly uses the lever dial indicator for point alignment, then inputs the theoretical coordinates and actual coordinates through the CAM software, and finally calculates the coordinate offset angle and offset amount. After calculating the output results, it is necessary to manually adjust the parameters of the machine tool. The input and output are manually operated and error-prone, and the whole process is cumbersome. There is a need for a program with the function of automatic collection...
