A Comprehensive Evaluation Method for Machining Performance of Materials

Abstract

The invention discloses a comprehensive evaluation method of material machinability. The material is an object of evaluation. The evaluation method comprises a step 1 of determining evaluation indexes of the machinability of the object of evaluation; a step 2 of measuring the evaluation indexes of the machinability of the object of evaluation; a step 3 of dividing, according to the influence of the evaluation indexes of the object of evaluation on the machinability, the evaluation indexes into useful indexes and useless indexes; a step 4 of standardizing the evaluation indexes of the object of evaluation; a step 5 of normalizing the standardized evaluation indexes of the object of evaluation; a step 6 of determining, based on a combination weighting method, weights of the evaluation indexes of the object of evaluation; a step 7 of drawing a radar map of the machinability of the object of evaluation; and a step 8 of evaluating the machinability of the object of evaluation comprehensively according to the radar map.

Description

technical field [0001] The invention relates to a comprehensive evaluation method for material cutting performance. Background technique [0002] With the rapid development of science and technology, various new and high-performance engineering materials have gradually come out. How to apply these new engineering materials to the industry reasonably, reliably, and make the best use of them requires a reasonable processing technology based on specific engineering materials. [0003] The establishment of a reasonable processing technology for engineering materials depends on the cutting performance of the material (that is, the degree of difficulty of the material during cutting). That is to say, to formulate a reasonable processing technology for a new material, we must first correctly understand the cutting performance of the new material. Only the processing technology formulated according to its specific performance is reasonable, correct and effective. [0004] The unde...

That is to compare the machinability of a certain material with that of another material. Generally, the 45 steel in the normalized state is used as the benchmark to evaluate the machinability of other materials. It is relatively simple, clear, convenient and accurate, and it is also At present, the most widely used method can better investigate the cutting performance of materials; however, it cannot reflect the overall cutting performance of materials and the relationship between various performance indicators, and the final conclusions cannot be obtained from the overall Comprehensively reflects the cutting performance of the material, that is to say, it still cannot give a comprehensive, comprehensive and accurate deterministic conclusion, and the reliability and practicability are also lacking.
