Experimental Study Of Surface Grinding Temperature Field By Cup Wheel Based On Computer Simulation

As a high accuracy, high rigidity, high efficiency processing method, surface grinding by cup wheel is being utilized into variant processing field. Because the contact area is a curve shape, its temperature distribution is more complex than that of the traditional surface grinding method. In this paper, the temperature field of surface grinding by cup wheel has been calculated and simulated based on finite element.Based on workpiece's material properties and operating conditions, a concise differential equation was proposed in a curve moving heating source. With the help of nonlinear finite element software ANSYS, a three-dimensional finite element model of the temperature field for transient state was set up, and the internal temperature field distribution was obtained. These results make it possible to analyses the surface grinding temperature field by cup wheel.In the actual grinding process, various factors are associated with each other and Have a comprehensive effect on the process, so it is difficult to find a chief influencing factor to a special processing phenomenon; Sometimes it is impossible to find it out. This paper uses single factor comparison method to analyze every influencing factor with the aid of computer science and system simulation knowledge. Some useful results are obtained, which are helpful to understand the surface grinding temperature field by cup wheel. Experimental results are also given to verify the theoretical outcome.This paper will surely enrich and widen the study in the field of surface grinding by cup wheel. Furthermore, it is to be an important sense of direction to the engineering practice. At the same time, it is helpful to analyses other problems emerged in mechanical processing such as face grinding and face milling.
