Description
Technical Field
The invention relates to the technical field of friction and wear tests, in particular to a friction experiment device for testing friction performance of a cutter coating.
Background
In the global competitive background, in order to improve the production and processing efficiency, the current industry generally adopts a very high cutting speed for the processing of the cutter, and under the severe processing condition of the high cutting state, extremely high mechanical stress and temperature can be generated at the cutting interface and around the cutting edge of the cutter, so that excessive abrasion and even premature failure of the cutter are generated in the production and processing process, and finally, the rejection rate is extremely high. Therefore, to prevent this, it is necessary to build accurate cutting process simulation, determine optimal cutting conditions in terms of tool material, tool geometry, and coating, and the like, and thus maintain high machining operation productivity to reduce rejection rate.
In order to study these tribological phenomena, i.e. mechanical stress problems and temperature problems, occurring at the processing interface, one of the methods of investigation by researchers is through laboratory simulation tests, several friction devices have been present or developed. The most widely known device is a pin-and-disc system, such as a small pin-and-disc contact reciprocating frictional wear test device disclosed in chinese patent No. 201810287951X, unfortunately this type of device cannot simulate the frictional contact conditions in cutting, because in this experimental method, the pin and the disc continuously repeatedly rub, and the friction surface during cutting is a new forming surface, so the frictional conditions (initial shape of the friction surface, temperature, pressure) simulated by the pin-and-disc system are inconsistent with the actual conditions of cutting, and therefore it cannot simulate the frictional conditions of the cutting process well. Furthermore, the contact pressures allowed with these systems are not suitable for heavy duty friction testing because the contact point pressures are difficult to reach 1GPa due to the lack of rigid contact.
Further investigations have been made by those skilled in the art to better simulate the experimental conditions of tool cutting friction, such as Olsson et al, which propose that a pin be placed after the cutting tool, the frictional sliding speed and contact temperature occur similarly in the dry process, but the contact pressure is still very low (about 15 MPa). The high sliding speeds (up to 400 m/min) of the Zemzemi et al design, which simulate higher contact pressures (up to 3 GPa), show that they provide high efficiencies of the relevant friction coefficients, however, the inventive device is very difficult to manage and the manufacture of the work pieces is very long and expensive. Furthermore, the friction duration of the device is very limited (about 10 seconds) and long-term wear testing is not possible. Hedeqvist et al propose a device with a cylindrical geometry in which the pin rubs against the rotating surface, can produce sufficient speeds (hundreds of meters per minute) and can be tested for a long period of time, but cannot provide sufficient local pressure (about 15 MPa) to simulate tribological phenomena occurring during processing.
It can be seen that in the prior art, there is no device that can provide both sufficient contact pressure and long test time for testing the cutting friction of a tool.
