Spatial modeling is widely used to study parts grinding processes to optimize them. Existing geometric models of the process do not take into account the microgeometry of the abrasive wheel surface after its dressing. This paper presents a general modular three-dimensional model of the rough and finish grinding wheel surfaces dressing with diamond pencil grain with two-sided face grinding. The presented model has been created based on unified modules: instrumental, orientation, and shaped ones. The spatial model of the wheel end face shape takes into account the relative motions of its one and the diamond pencil in the dressing process. Based on the developed model, the researches of the shaping accuracy of the tool face roughing and conical calibration sections after its dressing have been carried out. For the improvement of the shaping accuracy of the parts ends, the straightness ensuring methods of the wheels calibration sections when dressed on CNC and without machines are presented. For the first time, the proposed dressing of abrasive wheels with roughing and gauge sections for two-sided grinding of the crosses ends has been offered. It can be used in the processing of various parts. High precision of details ends forming is achieved by the use of wheels with rough and gauge sections, and quality – by the reduction of process heat stress. |
