Embodiment Construction

[0052] First move the probe to the approximate middle position of the hole to be aligned

[0053] Call the self-made probe program in MDI

[0054] Siemens system:

[0055] Extern L910 (REAL, REAL, REAL)

[0056] L910 (measure diameter, speed, input offset zero)

[0057] Then measure two points. For example, the first point A is input to G54 and the second point is input to G55. The measured aperture is 50, and the speed is 100.

[0058] Then the two-stage measurement procedure is

[0059] L910(50,100,1)

[0060] L910(50,100,2)

[0061] The self-made subroutine executed in the background is as follows:

[0062] PROC L910 (REAL CRD, REAL JGF, REAL LDG) SAVE defines subroutine parameters

[0063] R2=CRD; celiang banjing assigns value to variable

[0064] R3=JGF; sudu assigns value to variable

[0065] R4=LDG; lingdian assigns value to variable

[0066] R2=R2 / 2 assigns value to variable

[0067] R60=$AA_IM[X] Use system variables to extract the current coordinates

Abstract

The invention belongs to the technical field of numerical control machining, and particularly relates to a single-machine calculation-point-free automatic alignment 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. The numerical control machining center uses the measuring head for alignment and then directly inputs the measuring head into a specific area of an equipment operation system, needed parameters are automatically generated, programs are automatically read, human intervention is not needed, the error rate is reduced, time is saved, and production efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of numerical control processing, and particularly relates to a single-machine automatic alignment processing method free of calculation. Background technique [0002] For aircraft casing products, many special-shaped parts need to calculate the offset of the coordinates and angles between the actual coordinate system and the theoretical coordinate system of the workpiece through the position of the center point of the hole system. The traditional method is to first use a lever dial indicator for point alignment, then input the theoretical and actual coordinates through the CAM software, and finally calculate the coordinate offset angle and offset. After calculating and outputting the results, it is necessary to manually adjust the parameters of the machine tool. The input and output are both manual and error-prone, and the whole process is cumbersome. A program with automatic point collection and calculatio...
