Design of a device for precision shaping of grinding wheel macro- and micro-geometry

摘要

The selected modifications to the construction of grinding wheels were described which facilitate an increase in the material removal rate(grinding wheels with conic chamfer and grinding wheels with microdiscontinuities on the active surface).Using these background details,a suggested thesis was put forward regarding the need to develop a device which will allow for the shaping of the macrogeometry of the grinding wheel(cylindrical and conical surfaces) and the microdiscontinuities within the dressing operation simultaneously.The device was presented and prepared in two functional variants(horizontal and vertical mounting of the motor),then a prototype was described.An example of the grinding wheel active surface,shaped by using this device,was also presented.The theoretical analysis and experimental verification performed determine that the error of shaping the conic chamfer angle within the range of 0-1.5o,using the developed device,is approximately ±3%.
