Systems Approach to Off-Round Grinding
Off-round grinding performed on CNC cylindrical grinding is a relatively new process. This paper takes a systems approach and discusses the various inputs and outputs and highlights the potential problems that production engineers face in implementing this new process. The effect of the inputs to the off-round grinding process such as the grinding machine, wheel, grinding fluid and the workpiec...
متن کاملAssessment of Working Conditions of Grinding Wheels in the Grinding Process of Hard-To-Cut Materials
Abstract This study here by presents a method for comparative assessment of grinding wheels during the grinding process of hard-to-cut materials. The method in question consists of carrying out a short grinding cut in plunge grinding kinematics using grinding wheels with a customized macro-geometry upon the active surface. The work presents examples of this method’s efficacy when applied to the...
متن کاملSTUDY OF NUCLEAR LEVEL DENSITY AND SPIN CUT-OFF FACTORS
Nuclear level densities and spin cut-off factors have been deduced for nuclei in the mass region 24‹A‹63,from a microscopic theory, which includes nuclear pairing interaction. Single particle levels for both Seeger and Nilsson potentials were used in the calcdations. Level densities extracted from the theory are compared with their conesponding experimental values, It is found that the overall...
متن کاملCut-off Grade Optimization for Maximizing the Output Rate
In the open-pit mining, one of the first decisions that must be made in production planning stage, after completing the design of final pit limits, is determining of the processing plant cut-off grade. Since this grade has an essential effect on operations, choosing the optimum cut-off grade is of considerable importance. Different goals may be used for determining optimum cut-off grade. One of...
