Problems solved by technology

However, in the actual processing, since the processing route is set according to the theoretical parameters of the processing material (for example, the coordinates of the theoretical outer contour point), and the actual parameters of the processing material and the theoretical parameters inevitably have certain errors. Processing materials according to the processing route set on the basis of theoretical parameters will definitely lead to processed products that do not meet the processing requirements
[0003] In addition, there is a further problem with the machining method described above, because after cutting a large number of parts, the tool will wear
As the amount of tool wear increases, after exceeding a certain critical value, all the parts processed by the tool will become waste or substandard products
This creates a waste of a lot of resources and increases production costs.

Embodiment Construction

[0018] Such as figure 1 Shown is the operating environment diagram of the preferred embodiment of the processing program compensation system of the present invention. The processing procedure compensation system 10 is applied in the computer 1 . In this preferred embodiment, the computer 1 is connected with the processing equipment 2 and the image capturing device 3 . The computer 1 can also be a server, a host or other devices. Described processing equipment 2 can be all kinds of tool 20 (such as figure 2 shown) machine tools, such as cutting machines and other equipment.

[0019] The image capture device 3 may be a separate device connected to the computer 1 , or a charge-coupled device (CCD, Charge-coupled Device) image sensor installed on the processing equipment 2 . The image capturing device 3 can be used to photograph the working platform 21 placed on the processing equipment 2 (such as figure 2 The image of the product or material to be processed on the ) can al...

Abstract

A method for applying accuracy compensation to a computer numerically controlled (CNC) machine can compensate control program that controls the CNC machine. The method recognizes an actual outline of the product using an image of product produced by the CNC machine controlled by the control program, and further obtains an ideal outline of the product. The method obtains compensation values by computing coordinate differences between points of the actual outline and points on the ideal outline, and compensates the control program using the compensation values.

Description

technical field [0001] The invention relates to processing technology, in particular to a processing program compensation system and method. Background technique [0002] In the field of CNC machine tool processing in the prior art, automatic control is adopted. After setting the processing route (also known as "movement path") and processing amount of the tool, the tool executes the processing process of the part according to the established program, for example, cutting the material cut. The processing route is often determined according to the parameters of the material to be processed, for example, the outer contour of the processed material. However, in the actual processing, since the processing route is set according to the theoretical parameters of the processing material (for example, the coordinates of the theoretical outer contour point), and the actual parameters of the processing material and the theoretical parameters inevitably have certain errors. Processin...
