钛合金钻削的刀具断屑槽设计与钻削仿真
Tool Chip Breaker Design and Drilling Simulation for Titanium Drilling
摘要
Abstract
In order to meet the accuracy of drilling workpieces of difficult-to-machine materials,such as titanium alloys,while improving processing efficiency and reducing production costs,this paper presents a combination of theoretical analysis,numerical simulation and experiment.he chip breaker structure is designed for the chip breaking problem in the drilling process,and the thrust force,chip breaking process,strain state and chip shape under different machining parameters are studied.The results show that the maximum thrust force error between the experimental and simulated data ranges from 10％to 20％,and the chip fracture morphology aligns closely,confirming the reliability of the finite element model.The chip length decreases as the feed decreases;Under different processing parameters,the thrust force of the drill bit with chip breaker is less than that without groove;The interaction between the chip and the chip surface leads to curling,with both the degree of curl and the stress increasing as the tool feed rate rises.关键词
