Embodiment Construction

[0012] In order to make the technical means, creative features, work flow, and use methods of the present invention achieve the purpose and effect easily understood, the specific implementation of the present invention will be further elaborated below in conjunction with the accompanying drawings and specific examples. Similar extensions are made under the connotation of the invention, so the present invention is not limited by the specific embodiments disclosed below.

[0013] There are two types of on-line measurement methods of the CNC system: one is to directly call the basic macro program program without the computer, such as figure 1 shown; the other is that the user develops the macro program by himself. Different macro programs can be written according to the specific detection requirements, and uploaded to the numerical control system by using the computer-aided system for measurement control such as figure 2 As shown, both measurement methods can measure the incline...

Abstract

The invention provides a key online inclined hole measuring method through a numerical-control machine tool, and machining and measuring are conducted on the same equipment. By the adoption of the method, secondary swivel-clamp errors can be effectively avoided, a machine tool measuring head is added and installed in a tool magazine system of a numerical-control system, in the workpiece machining process, a measurement macroprogram is edited in advance, measurement of a machined workpiece can be conducted at any time according to technological requirements, and the effect that machining and measuring are conducted at the same time is achieved indeed. Discarded products can be found as early as possible, labor cost is reduced, productivity is liberated, and machining waste is reduced.

Description

technical field [0001] The patent of the invention relates to a key method for online measurement of inclined holes by a numerical control machine tool, which belongs to the field of machinery, and in particular relates to a method for online measurement of inclined holes. Background technique [0002] Due to the serious backwardness of my country's mechanical processing technology, there is a lack of core key technologies, especially in terms of hardware. It is even more difficult to develop an online measurement method on a five-axis machine tool. The deviation of the accuracy of each key part will cause a series of errors in the measurement of the workpiece. The method of the invention is to analyze the practicability and feasibility of on-line measurement of the five-axis numerical control machine tool by using the multi-body system kinematics theory and error modeling, and the analysis of the motion error of the five-axis machine tool. Contents of the invention [00...
