Method for turning tensile samples of different feeding profiles by using macro program=

Abstract

The invention discloses a method for turning tensile samples of different feeding profiles by using a macro program. The method comprises the following steps: 1, variable quantities of samples of different shapes are analyzed, design and assignment of macro program variables are completed, and an assigned macro variable contains complete machining parameters of all the samples; 2, according to theassignment macro variable, the turning machining of the macro program is programmed; and 3, according to the turning process of the macro program for the tensile samples, when a specific sample is machined, a program segment corresponding to the missing assigned macro variable in the sample is skipped through a skipping function. According to the method, the macro program can be used for machining the tensile samples with different shapes and sizes, so that a large amount of time occupied by the program during the change of the shapes of the samples is reduced, and the possibility that because multiple programs occupy the system memory, the response speed of a machine tool and wrong debugging of the program is avoided.

Description

technical field [0001] The invention relates to the technical field of metallurgical production, in particular to a method for turning a tensile sample with different cutting contours by using a macro program. Background technique [0002] Metal materials are the main body of engineering materials, and their mechanical properties are very important properties in engineering applications. The sample is used as the carrier of various properties of the metal material, and the test data of various mechanical properties are obtained through tensile tests. Therefore, the processing of samples is the guarantee test. The primary factor in the correctness of the results. Most of the mechanical properties of medium and thick plates and profiles need to be machined into circular cross-section tensile specimens according to the inspection method standards. There are mainly three types of sample shapes commonly used. Compared with the standards of China, the United States, Japan, and th...

Problems solved by technology

[0003] When processing tensile samples by CNC lathe, a general CNC program (constant programming) can only describe a sample of one shape and size specification, even if a macro program (variable programming) is used, it can only solve the same shape but different specifications For the processing of series workpieces, when the shape of the sample changes, it can only be reprogrammed. The development of the program takes up a lot of time, which seriously affects the progress of the application to the actual processing.
