Test method for testing cutting performance of diamond saw blade

The invention belongs to the technical field of diamond tool testing, and discloses a test method for testing the cutting performance of a diamond saw blade, which solves the problem in the prior art that existing test methods for testing the cutting performances of diamond cutters are not accurate and not uniform. The test method comprises the following steps of 1, obtaining a set load parameter value: controlling the feed quantity of a diamond saw blade, finding a load value K of the diamond saw blade when the feed quantity of the diamond saw blade on a cutting object is maximal, and setting M= 0.70K-0.85K, wherein M is the set load parameter value; 2, during the cutting process, controlling the cutting load value of the diamond saw blade to be 0.9M-1.1M by means of a servo system. According to the technical scheme of the invention, the unification of three cutting elements, namely a machine tool, an object and a feed thrust, is realized. Meanwhile, the cutting performance of a diamond cutter can be automatically and accurately tested. Therefore, a unified and standard testing standard is formed for the industry and the perfect development of the diamond tool industry is ensured.
