Abstract


Deep hole processing is an important process in the machining method. The maindeep hole machining tool is twist drill for deep hole drilling. At present, thetraditional design method is used as the main method of twist drill for deep holedrilling design, which is difficult to meet current design requirements, because of theheavy workload, low design accuracy and long design cycle. Based on3D parametricmodeling methods, the design process can be simplified and the design accuracy canbe further improved. Integrated use of CAD and CAE technologies in productdevelopment and design process, which can replace part of the actual test, the staticand dynamic performance of tools can be comprehensively analyzed and improvedbefore the sample produced.When the twist drill for deep hole drilling is cutting the workpiece (especiallyhigh-strength materials), the drill tip would surfer greatly cutting force, which couldpeel off or collapse the blade and blade tip. Therefore, the geometry parameters ofdrill tip should be reasonable to minimize the cutting force and the strength of thematerial of the twist drill for deep hole drilling should be ensured, which could reducedamage of the twist drill for deep hole in the process of cutting and prolong its life.Based on the3D parametric design module of twist drill for deep hole drilling, thegeometric parameters of twist drill for deep hole drilling were selected as optimizingroles and the optimization target is to let drilling force to a minimum. Integrated useof Finite element simulation and muti-orthogonal nonlinear regression test designmethods, the mathematical model of the drilling force was established andoptimization was reached by using genetic algorithm.The3D parametric design module applied technology of database and solvedproblems of the traditional design process, such as low efficiency, heavy workloadand poor accuracy. The modules can quickly and accurately generate3D model oftwist drill for deep hole drilling. Used3D parametric design and finite elementsimulation technology to achieve the optimization of geometrical parameters of twistdrills for deep hole drilling, the number of tests and the cost of optimization weregreatly reduced.
