Processing Optimization of High Speed Machining in Numerical Control Manufacturing

Abstract

High cost and low efficiency problem has been bothering NC teaching.To lower the cost of practical teaching of higher speed numerical control manufacturing along with improvement in processing efficiency, a multi-objective scheme for optimization of process parameters has been developed here. Various constraint conditions were set and a complex algorithm was employed for optimization. To achieve high production efficiency, lowering processing cost and comprehensive optimization, a mathematical model to calculate optimal cutting parameters with high accuracy is present- ed here. Specifically, basic elements for numerical control manufacturing and different types of cooling manufacturing were analyzed. Optimization of major parameters, such as cutting speed, radial cutting quantity and back engagement of cutting edge are discussed here. These parameters provide a reference for proper selection of processing parameters dur- ing machining. The feasibility of this scheme was validated by application in practical teaching, which improves pro- cessing efficiency and reduces cost of experimental materials.
