Problems solved by technology

However, the detection equipment is expensive and the process is cumbersome
[0008] Based on the above, every current part size measurement method must rely on external measurement tools, which is time-consuming
In addition, different types of dimensional inspections require different gauges, resulting in higher costs

example 1

[0070] N: "10", MTYPE: "Pstart", MARK: "10", DE: "-0.01", UE: "0.01", SPD: "1", NUM: "3", KFACT: "cur".

example 2

[0072] N: "50", MTYPE: "Pend", MARK: "10", DE: "-0.01", UE: "0.01", SPD: "1", NUM: "3", KFACT: "cur".

[0073] In the above example 1, N: "10" means starting from the 10th line of the first G code, MTYPE: "Pstart" means the starting point of length size evaluation, MARK: "10" means the element to be evaluated is 10mm in length size, DE : "-0.01" indicates that the lower deviation is -0.01, UE: "0.01" indicates that the upper deviation is 0.01, SPD: "1" indicates that the evaluation data sampling mode is mode 1 in Table 1 (that is, continuous fixed-point sampling), NUM : "3" indicates that the total number of sampling points is 3.

[0074] The above example 2 is the same as example 1, indicating the length dimension evaluation, MTYPE: "Pend" indicates the end point of the corresponding length dimension evaluation, and the corresponding relationship between the end point and the starting point is determined by the evaluation element identifier of MARK: "10".

Abstract

The present invention provides a method for evaluating the processing size of parts, including: running the first G code and the second G code at the same time, so as to obtain the processing data of the first G code for the part elements to be evaluated through the second G code, said The first G code is used to control the tool to process the part, and the second G code is used to use the first G code for the processing data of the part element to be evaluated and the information of the part element to be evaluated. Correlate; calculate the actual processing size of the part element to be evaluated according to the obtained processing data; and compare the calculated actual processing size of the part element to be evaluated with the standard specified in the part processing requirements for the part element to be evaluated The dimensions are compared to determine an evaluation result indicating whether the part element to be evaluated of the part meets the processing requirements of the part.

Description

technical field [0001] The present invention generally relates to the technical field of numerical control machining, and more specifically relates to a method for evaluating part machining dimensions and a corresponding device for realizing the method. Background technique [0002] In the field of mechanical processing, the level of processing accuracy is an important indicator for evaluating the quality of parts. Usually, after the parts are processed, it is necessary to use measuring equipment to measure the dimensions of the key or important elements of the parts (such as the length, angle, surface roughness, geometric shape and mutual position error of the parts) to determine whether the parts qualified. [0003] figure 1 is a flowchart illustrating a conventional part size evaluation process 100 . Such as figure 1 As shown, at block 110, the part under test is prepared. At block 120, the elements to be measured are determined. At block 130, the element under test...
